Commercial battery storage can help businesses reduce electricity costs, improve solar self-consumption and better manage energy usage. But choosing the wrong system can lead to unnecessary costs, poor performance and a longer return on investment.

Whether you operate a warehouse, factory, retail store, office, hospitality venue or other commercial property, there are several important factors to consider before investing in battery storage.

Here are 10 common mistakes businesses make when buying a commercial battery — and how to avoid them.

1. Choosing a Battery Based Only on Its kWh Capacity.

A common mistake is assuming that a larger battery automatically means greater savings.

For example, a 200kWh battery isn’t necessarily better than a 100kWh battery for every business.

The right size depends on factors such as:

• Your electricity consumption
• Solar generation
• Operating hours
• Evening and overnight consumption
• Peak demand
• Electricity tariff structure
• Available solar capacity
• Your business’s load profile

A properly sized system can often provide better financial returns than simply choosing the biggest battery available.

Tip: Your battery should be sized around your actual energy usage, not just your property’s available space.

2. Not Looking at the Business’s Electricity Usage

Your electricity bill contains valuable information that can help determine whether battery storage makes financial sense.

Businesses should look at:

• Total electricity consumption
• Peak demand
• Usage patterns throughout the day
• Energy rates
• Solar exports
• Evening consumption
• Seasonal variations

Two businesses with the same building size can have completely different battery requirements.

Before purchasing a battery, review your electricity bills and consumption profile.

3. Buying a Battery Without Considering Solar

Commercial batteries and solar systems often work best when designed together.

If your business already has solar, the battery can potentially store excess solar generation for use later in the day.

For businesses considering a new system, combining:

Solar + Battery + Energy Management

can provide a more complete energy strategy.

However, simply adding a large battery to a solar system doesn’t guarantee maximum savings. The system needs to be designed around how your business actually consumes electricity.

4. Ignoring Peak Demand

For some commercial customers, reducing peak electricity demand can be just as important as reducing total energy consumption.

A battery may be able to discharge during periods of high demand, depending on the tariff structure and system configuration.

This is why looking only at your total kWh usage can give you an incomplete picture.

A commercial battery assessment should consider both energy consumption and demand patterns.

5. Choosing the Cheapest Quote

Price is important — but the cheapest commercial battery quote isn’t always the best investment.

When comparing quotes, businesses should consider:

• Battery chemistry
• Usable capacity
• Inverter capacity
• Warranty
• System efficiency
• Installation requirements
• Monitoring
• Safety features
• Scalability
• After-sales support
• Expected operating conditions

A cheaper system may have different specifications that make direct price comparisons misleading.

Always compare the complete system, not just the advertised battery capacity.

6. Not Checking Battery Usable Capacity

Battery manufacturers may advertise a particular nominal capacity, but the amount of energy that can actually be used can be different.

Businesses should ask about:

Nominal capacity vs usable capacity

For example, two batteries advertised as “100kWh” may not necessarily provide the same usable energy.

Other important specifications include:

• Depth of discharge
• Round-trip efficiency
• Charge/discharge power
• Operating temperature
• Expected cycle life

These details can make a significant difference to long-term performance.

7. Forgetting About Inverter Capacity

The battery isn’t the only important component.

The inverter determines how much power the system can deliver or absorb at a particular time.

For example, a large battery paired with an undersized inverter may not be able to deliver the required power during periods of high demand.

That’s why commercial battery design should consider both:

kWh = energy storage capacity

kW = power output

You need the right balance between the two.

8. Not Thinking About Future Energy Requirements

Your business may grow.

You could add:

• EV chargers
• Refrigeration
• Machinery
• Air conditioning
• Additional production equipment
• Larger premises
• More solar panels

A battery system that works today may not necessarily be ideal five years from now.

When comparing systems, ask whether the solution can be expanded or integrated with future energy upgrades.

Planning for future requirements can prevent expensive system changes later.

9. Assuming a Battery Automatically Provides Backup Power

Another common misconception is that installing a commercial battery automatically means the business will have backup power during a grid outage.

That’s not always the case.

Backup functionality depends on the system design, inverter configuration, switchboard requirements and the loads that need to remain operational.

If backup power is important to your business, discuss it during the initial system design.

For some businesses, keeping critical equipment running during an outage can be a major consideration.

10. Getting a Battery Quote Without a Proper Energy Assessment

Perhaps the biggest mistake is purchasing a system based on a basic phone conversation or a generic battery package.

Every business has different:

• Energy consumption
• Operating hours
• Solar generation
• Electricity tariffs
• Peak demand
• Available installation space
• Future energy requirements

A proper assessment can help determine whether battery storage is suitable and what system size makes sense.

Thinking about installing solar but unsure whether you should stay connected to the electricity grid or become completely energy independent?

Choosing between Off-Grid Solar vs Grid-Connected Solar depends on your location, energy consumption, budget, battery requirements and how much independence you want from the electricity grid.

For some homeowners, a grid-connected solar system with battery storage can provide excellent savings while keeping the grid available as a backup. For remote properties, farms and homes where grid access is limited or expensive, an off-grid solar system may be a better solution.

What Is Off-Grid Solar?

An off-grid solar system operates independently from the electricity grid.

A typical system includes:

• Solar panels
• Battery storage
• An off-grid or hybrid inverter
• Battery management equipment
• Backup generation where required

The solar panels generate electricity during the day, while batteries store excess energy for use at night or during periods of low solar production.

Because there is no grid available as a backup, the system needs to be carefully designed around your household’s electricity consumption.

What Is Grid-Connected Solar?

A grid-connected solar system remains connected to the electricity network.

Solar panels generate electricity during the day, and your home can use that energy directly. Excess electricity can be exported to the grid, depending on your electricity plan and local requirements.

Adding a battery can allow you to store surplus solar energy and use it later when your panels aren’t producing enough electricity.

This can provide a balance between energy savings, battery storage and grid reliability.

Off-Grid Solar vs Grid-Connected Solar:

• Feature Off-Grid Solar Grid-Connected Solar
• Electricity grid Not required Required
• Battery Essential Optional
• Energy independence Very high Moderate to high
• Backup during grid outage Built into system Depends on system design
• System complexity Higher Generally simpler
• Upfront investment Usually higher Usually lower
• Suitable for remote properties Excellent Depends on grid availability
• Generator backup Sometimes recommended Usually unnecessary

Which System Costs More?

An off-grid system generally requires more equipment because it needs enough solar generation and battery capacity to meet your electricity requirements without relying on the grid.

The cost can increase further if you need:

• Larger battery storage
• Additional solar panels
• High-capacity inverters
• Generator backup
• Special installation requirements
• Larger backup reserves for periods of poor weather

A grid-connected solar system can often be smaller because the electricity grid remains available when solar production isn’t enough.

However, the cheapest system isn’t necessarily the best system.

The right solution should be based on your actual electricity consumption and energy goals.

How Much Battery Storage Do You Need for Off-Grid Solar?

Battery sizing is one of the most important parts of an Off-Grid Solar vs Grid-Connected Solar .

A home using relatively little electricity may require a smaller battery bank, while a larger household running air conditioning, pumps, refrigeration, electric hot water or other high-consumption appliances may require significantly more storage.

You also need to consider how many hours or days of backup energy you want.

For example, designing a system only around average daily consumption may not provide enough energy during several cloudy days.

That’s why professional system design should consider:

Daily consumption + peak demand + solar production + battery capacity + backup requirements.

What Happens During Cloudy Weather?

This is one of the biggest considerations when going off-grid.

Solar production can fall significantly during periods of heavy cloud or poor weather. An off-grid system therefore needs enough battery storage and solar generation to maintain reliable power.

Some properties may also benefit from a backup generator.

A properly designed system should account for seasonal changes rather than relying only on average summer solar production.

Who Should Consider Off-Grid Solar?

Off-grid solar can be particularly attractive for:

• Rural properties
• Farms
• Remote homes
• Properties with limited grid access
• New developments where grid connection is expensive
• Homeowners seeking greater energy independence
• Properties where extending the electricity network isn’t practical

If your property already has a reliable and affordable grid connection, completely disconnecting from the grid may not always provide the best financial return.

Who Should Choose Grid-Connected Solar?

Grid-connected solar may be more suitable if:

• You already have a reliable grid connection
• You want to reduce electricity bills
• You don’t want to manage a completely independent energy system
• You want solar without a large battery investment
• You want the grid available during periods of low solar generation

You can also add battery storage later if your energy needs change.

What About Solar + Battery Instead of Going Completely Off-Grid?

For many homeowners, this can be the middle ground.

A grid-connected solar + battery system can provide significant energy independence while maintaining access to the electricity grid when required.

During the day, solar can power your home and charge the battery. At night, stored energy can be used instead of purchasing as much electricity from the grid.

Depending on the system and installation, battery backup can also provide power to selected loads during a grid outage.

So, Which One Is Right for You?

There isn’t one answer for every property.

Choose off-grid solar if your priority is maximum energy independence and your property is remote or unsuitable for a practical grid connection.

Choose grid-connected solar if your priority is reducing electricity costs while keeping the grid available as a reliable energy source.

Consider solar + battery if you want to reduce your reliance on the grid without completely disconnecting from it.

The most important step is understanding how much energy your property actually uses before deciding on system size.

Choosing a commercial battery is not simply a matter of picking the biggest system that fits your budget.

For Australian businesses, the right battery size depends on how much electricity you use, when you use it, how much solar you generate, your peak demand, available space and how you want the battery to operate.

A 50kWh battery may be more than enough for one business, while a larger warehouse, factory or hospitality business may benefit from 100kWh, 200kWh or considerably more.

So how do you know which option makes sense for your business?

In this guide, we compare 50kWh, 100kWh and 200kWh+ commercial battery systems, what each can potentially be used for, and the factors you should consider before investing.

Why Are Businesses Installing Commercial Batteries?

Solar panels can significantly reduce the amount of electricity a business purchases from the grid during daylight hours.

But there is a problem for many businesses:

Your electricity usage doesn’t always match your solar production.

A business may generate plenty of solar around midday but still consume electricity:

• Early in the morning
• Late in the afternoon
• In the evening
• Overnight
• During periods of high production or demand

A battery allows excess solar generation to be stored and used later, helping businesses increase the amount of generated energy they can consume themselves.

For some businesses, battery storage can also form part of a broader strategy to manage periods of high electricity demand.

The Australian Government’s energy guidance notes that commercial batteries can help businesses store solar energy for later use and potentially reduce electricity purchases and peak demand, depending on the business and tariff structure.

50kWh vs 100kWh vs 200kWh+: What’s the Difference?

There isn’t one battery size that is right for every business.

Think of battery capacity as the amount of energy the battery can store.

For example:

• 50kWh = up to 50kWh of stored energy
• 100kWh = up to 100kWh
• 200kWh = up to 200kWh

Actual usable capacity, charge/discharge limits and system performance depend on the battery technology, inverter, configuration and operating conditions.

Here’s a simplified comparison:

Battery size Often worth considering for Typical objective
50kWh Small businesses, offices, retail, smaller commercial sites Solar self-consumption
100kWh Medium commercial sites, larger retail, hospitality Greater solar utilisation + peak management
200kWh+ Large facilities, warehouses, factories, high-energy businesses Large-scale energy management

These are general categories rather than strict rules. A business shouldn’t select a battery purely based on its size.

Is a 50kWh Commercial Battery Enough?

A 50kWh battery can be a practical starting point for businesses that have moderate electricity consumption and a suitable solar system.

It can be particularly relevant for businesses that want to:

Store excess solar

Instead of exporting surplus solar generation during the day, the battery can store some of that energy for later use.

Increase solar self-consumption

If your business has electricity demand outside the strongest solar-generation hours, stored energy can potentially be used later.

Reduce grid reliance

Using stored energy when appropriate can reduce the amount of electricity purchased from the grid.

Keep the system relatively compact

A smaller battery generally requires less physical space than a larger commercial installation, although installation requirements vary considerably between products and sites.

Who might consider 50kWh?

Examples could include:

• Small offices
• Retail stores
• Cafés and restaurants
• Professional practices
• Small warehouses
• Workshops
• Smaller commercial buildings

But the important question isn’t simply:

“Do I need 50kWh?”

It’s:

“How much energy does my business actually need to store?”

When Does a 100kWh Battery Make Sense?

A 100kWh battery provides roughly twice the nominal storage capacity of a 50kWh system.

For businesses with higher daytime solar generation and greater electricity consumption, this can provide more flexibility.

A 100kWh system may be worth investigating when a business has:

• A larger commercial solar system
• Significant daytime electricity consumption
• Meaningful electricity usage after sunset
• Higher daily energy consumption
• Greater surplus solar generation
• A need for more substantial energy storage

For example, imagine a business produces substantial excess solar energy during the middle of the day but continues operating well into the evening.

A larger battery may allow more of that solar energy to be shifted from the middle of the day into later operating periods.

However, bigger doesn’t automatically mean better.

If your business regularly has insufficient excess solar to charge a 100kWh battery, installing additional storage may not provide the expected financial benefit.

What About 200kWh+ Commercial Batteries?

Once you move into the 200kWh+ range, you’re generally looking at substantially larger commercial energy-storage applications.

These systems may be relevant for businesses such as:

• Manufacturing facilities
• Large warehouses
• Distribution centres
• Shopping centres
• Large hospitality operations
• Agricultural businesses
• Cold storage facilities
• High-energy commercial sites
• Businesses operating for extended hours

A larger battery can provide considerably more stored energy, but the economics become increasingly dependent on the site’s actual electricity profile.

For these projects, battery sizing should generally be based on detailed energy data rather than a simple rule of thumb.

The Biggest Mistake: Choosing a Battery Based on Solar Size Alone

One of the most common mistakes businesses can make is thinking:

“I have a 100kW solar system, so I need a 100kWh battery.”

That’s not necessarily correct.

Solar capacity and battery capacity are two different things.

A 100kW solar system describes the potential power output of the solar array under appropriate conditions.

A 100kWh battery describes its nominal energy storage capacity.

Your battery should be assessed alongside:

• Solar generation
• Electricity consumption
• Load profile
• Peak demand
• Operating hours
• Electricity tariff
• Export arrangements
• Battery power rating
• Available installation space
• Future energy requirements

Your Electricity Bill Can Tell You a Lot

One of the easiest ways to start assessing battery requirements is to look at your business electricity bills.

But the total bill isn’t enough.

A proper assessment should ideally examine interval electricity data where available.

This can show:

• When are you using electricity?
• How much electricity are you using?
• When does your demand peak?
• How much solar are you currently exporting?
• What happens outside your solar-generation hours?

These answers are much more useful than simply looking at your monthly electricity spend.

Battery Size vs Battery Power: Don’t Confuse the Two

This is particularly important for commercial systems.

kWh = energy capacity

kW = power

A 100kWh battery doesn’t automatically mean it can deliver 100kW of power.

For example, depending on the system configuration, a battery could have:

100kWh capacity + 50kW power

or another power-to-energy ratio.

Why does this matter?

Imagine a business has a large short-duration power requirement.

Having plenty of stored energy isn’t necessarily enough if the battery and inverter cannot provide the required power at that moment.

That’s why commercial battery design should consider both energy capacity and power requirements.

How Long Can a Commercial Battery Run My Business?

This is one of the most common questions businesses ask.

The answer depends on your actual load.

A simplified example:

If a business was consuming an average of 25kW, then a 100kWh battery could theoretically provide around:

100 ÷ 25 = 4 hours

However, this is only a simplified calculation.

Real-world operation depends on factors such as:

• Usable battery capacity
• Battery state of charge
• Inverter efficiency
• Maximum discharge rate
• Simultaneous loads
• Operating conditions
• System controls

Therefore, you shouldn’t assume that a 100kWh battery will automatically provide four hours of backup or operation.

Should I Choose 50kWh, 100kWh or 200kWh+?

Here’s a simple way to think about it.

Consider 50kWh if:

Your business has moderate energy consumption and you’re primarily looking to increase solar self-consumption and shift some excess solar into later periods.

Consider 100kWh if:

You have a larger solar installation, higher electricity consumption and enough surplus solar or suitable operating economics to justify additional storage.

Consider 200kWh+ if:

Your business has substantial energy consumption, large solar generation, significant peak demand or extended operating hours that can make larger-scale storage worthwhile.

But don’t make the final decision from a generic table.

Your electricity data should determine the system.

What Does a Commercial Battery System Cost?

There isn’t a single price for a 50kWh, 100kWh or 200kWh commercial battery.

The installed cost can depend on:

• Battery brand and technology
• Inverter capacity
• Number of battery modules
• Switchboard upgrades
• Electrical infrastructure
• Installation complexity
• Site access
• Monitoring and control systems
• Backup requirements
• Civil works
• Compliance requirements
• Network requirements

That’s why comparing batteries purely on $/kWh can be misleading.

A cheaper battery may not provide the same power output, warranty, integration capabilities or installation requirements as another system.

Is a Bigger Commercial Battery Always Better?

No.

The objective isn’t to install the largest battery possible.

The objective is to install a battery that makes sense for the business.

For example, if a 200kWh battery frequently sits partially charged because there isn’t enough excess solar or suitable evening consumption, the additional capacity may not provide the expected return.

On the other hand, if a business consistently has substantial excess solar and significant electricity consumption later in the day, a smaller battery could leave valuable solar energy unused.

The right system is about matching storage to your energy profile.

What Information Do You Need to Size a Commercial Battery?

Before recommending a commercial battery, an installer or energy specialist will typically want information such as:

1. Electricity bills

Ideally, several recent bills.

2. Interval data

Where available, this can provide much better insight into your consumption pattern.

3. Solar system details

Existing or proposed solar capacity, inverter specifications and expected generation.

4. Business operating hours

A business operating 24/7 has a very different energy profile from one operating 8am–5pm.

5. Site details

Roof area, switchboard configuration and available battery installation space can all matter.

6. Your objective

Are you primarily looking to:

• Reduce electricity costs?
• Increase solar self-consumption?
• Manage peak demand?
• Reduce grid reliance?
• Add energy resilience?
• Prepare for future electrification?

The answer can influence the ideal system configuration.

What About Battery Backup?

If you’re considering a battery because you want protection during a grid outage, make sure you specifically discuss backup capability.

Not every commercial battery installation automatically provides whole-business backup.

The required system may depend on:

• Essential loads
• Switchboard configuration
• Inverter capability
• Battery power output
• Automatic transfer equipment
• Generator integration
• Site electrical design

A business might therefore choose to back up only critical equipment rather than the entire facility.

The Right Commercial Battery Is About Your Business, Not a Number

A 50kWh battery isn’t necessarily better than a 100kWh battery.

And a 200kWh system isn’t automatically the best investment.

The right solution depends on the relationship between:

Solar generation → Business consumption → Battery storage → Grid usage

The goal is to design a system that works with your actual operating profile.

For some businesses, that could mean 50kWh.

For others, 100kWh may be more appropriate.

And for high-energy commercial facilities, a 200kWh+ system may be worth investigating.

Want to Know What Size Battery Your Business Actually Needs?

Rather than guessing between 50kWh, 100kWh and 200kWh+, get your business’s energy usage assessed against its solar generation and operating profile.

A commercial solar and battery assessment can help determine:

• Recommended battery capacity
• Required inverter power
• Solar system size
• Potential energy savings
• Battery utilisation
• Potential payback
• Suitable financing options

Submit your business details and electricity information for a commercial solar + battery assessment.

FAQs: What Size Commercial Battery Do I Need? (50kWh vs 100kWh vs 200kWh+)

1. How do I know what size commercial battery my business needs?

The right battery size depends on your daily energy consumption, peak power demand, backup duration requirements, and whether you’re using solar. Review your electricity bills and identify how much energy (kWh) your business uses during the hours you want battery support.

2. Who is a 50kWh commercial battery best for?

A 50kWh battery is ideal for small businesses such as retail stores, cafés, offices, clinics, salons, and small workshops. It can provide backup power for essential loads or reduce electricity costs during peak tariff hours.

3. Is a 100kWh battery enough for a medium-sized business?

Yes. A 100kWh battery is a common choice for medium-sized businesses, including restaurants, supermarkets, warehouses, schools, and manufacturing units with moderate energy needs. It offers longer backup time and greater savings through peak shaving.

4. When should I consider a 200kWh or larger battery system?

Choose a 200kWh+ battery if you operate a large commercial facility, factory, data center, hotel, hospital, or logistics hub with high energy consumption. These systems support larger loads, longer backup times, and integration with larger solar installations.

5. What’s the difference between kWh and kW?

• kWh (kilowatt-hour): Measures how much energy the battery stores.
• kW (kilowatt): Measures how much power the battery can deliver at one time.

A battery may store 100kWh but have a power output of 50kW or 100kW, depending on its design.

6. How long will a commercial battery provide backup power?

Backup time depends on the connected load. For example:

Battery Size	Approximate Backup
50kWh	~5 hours for a 10kW load
100kWh	~5 hours for a 20kW load
200kWh	~5 hours for a 40kW load

Actual backup duration varies based on battery efficiency and depth of discharge.

7. Can I use a commercial battery without solar panels?

Yes. Commercial batteries can charge from the electrical grid and provide backup during outages or reduce demand charges. However, pairing a battery with solar usually increases long-term savings.

8. Can I expand my battery system later?

Many commercial battery systems are modular, allowing you to add additional battery units as your energy needs grow. Check compatibility with your inverter and battery management system before expanding.

9. How much can a commercial battery reduce electricity bills?

Savings depend on your tariff structure and usage pattern. Businesses can reduce costs through peak shaving, time-of-use energy shifting, solar energy storage, and avoiding high demand charges.

10. What factors affect the battery size I should choose?

Consider:

• Daily energy usage (kWh).
• Peak demand (kW).
• Required backup duration.
• Critical equipment that must stay powered.
• Solar system size (if applicable).
• Future business expansion plans
