One System, Everything Included
The GoodWe ESA Series removes the guesswork from home energy storage. Unlike traditional setups where you need to separately source an inverter, battery, and monitoring system and pay for each to be installed individually the ESA comes pre-wired as a single modular unit. That means faster installation, fewer points of failure, and a simpler monitoring experience through one app. For homeowners looking to maximise solar self-consumption and reduce reliance on grid power during peak tariff hours, the ESA is designed to work straight out of the box.
Start Small, Scale When You Need To
Not every household needs maximum storage from day one. The GoodWe ESA lets you start with a single 5 kWh or 8 kWh module and expand as your energy needs grow mixing module sizes and adding up to 12 modules per stack for a maximum capacity of 108 kWh. This modular approach means you’re not over-investing upfront. As electricity prices rise and your household consumption increases, you can add capacity without replacing the entire system. Ideal for growing families, homeowners adding an EV, or anyone planning ahead for rising energy costs.
Whole-Home Backup Without the Extra Hardware
Most home battery systems require a separate gateway device to provide backup power the GoodWe ESA doesn’t. It delivers UPS-level, full-house backup built in, switching to battery power in under 4 milliseconds fast enough that your devices won’t even notice the grid went down. For homeowners in areas prone to summer storms, bushfire-related outages, or unreliable grid infrastructure, this means your lights, fridge, internet, and essential appliances keep running without interruption no manual switching, no extra equipment, no extra cost.
Built for Maximum Solar Performance
The GoodWe ESA is engineered to get the most out of your solar system, not just store energy. With a 1C charge and discharge rate, the battery can absorb and release energy quickly important for households with high daytime consumption or time-of-use tariffs where speed of charging matters. Support for 20A input per string and up to 200% PV oversizing means the ESA works efficiently even on cloudy days or in suboptimal panel orientations a practical advantage for rooftops where conditions vary significantly by season and location.

Yes. The GoodWe ESA provides UPS-level, full-house backup with no gateway required. It switches to battery power in under 4 milliseconds fast enough that your appliances, lights and internet stay running without interruption during a blackout or grid outage.
The GoodWe ESA comes with a 10-year product and performance warranty. Before installation, we recommend confirming labour and transport coverage in writing with your installer, as GoodWe handles these on a case-by-case basis.
The cost depends on the system size, number of battery modules and installation requirements. The ESA starts with a single 5 kWh or 8 kWh module and scales up to 48 kWh (single phase) or 108 kWh (three phase). Contact Easy Solar for a free quote tailored to your home.
Yes. The GoodWe ESA is compatible with both new and existing solar installations. It integrates the hybrid inverter and battery into one unit, so it can be added to your current setup without replacing your panels.
The single phase ESA supports 3–10 kW inverter output and up to 48 kWh storage (6 modules per stack). The three phase ESA supports 5–30 kW and scales up to 108 kWh (12 modules per stack), making it better suited for larger homes or small commercial properties with higher energy demands.
