The EcoBridge 30.3 kWh Battery System, paired with the Alpha ESS SMILE-S5 G3 5 kW Hybrid Inverter (supporting up to 10 kW of solar PV input), delivers a premium, high-capacity energy storage solution designed for large homes, households with significant evening energy consumption, EV owners, and those seeking enhanced energy independence or partial off-grid capability.
Engineered to maximise solar self-consumption, this advanced EcoBridge energy solution stores excess solar energy generated during the day for use at night, during peak electricity pricing periods, or during grid outages. By reducing reliance on the grid, homeowners can lower electricity costs while ensuring uninterrupted power to essential household circuits.
This system enables homeowners to:
- Maximise solar energy usage both day and night
- Reduce electricity bills through increased solar self-consumption
- Maintain essential household power during blackouts
- Take advantage of available Australian federal and state battery rebate programs
Featuring 30.3 kWh of usable battery storage and a 5 kW hybrid inverter, this package provides:
- Efficient charging from solar arrays up to 10 kW
- Seamless integration with single-phase residential electrical systems
- Intelligent automatic switching between solar, battery, and grid power
Under typical operating conditions, this system can support substantial household loads — including air conditioning, EV charging, pool pumps, lighting, refrigeration, and everyday appliances — for approximately 24 to 36 hours, depending on energy consumption patterns.
Backed by a 10-year product warranty, advanced Alpha Cloud smart monitoring, and professional CEC-accredited installation through EcoBridge, this high-performance energy storage solution delivers exceptional reliability, enhanced energy security, and long-term savings for Australian homeowners.
