Why GoodWe
What makes GoodWe ESA stand out
All-in-one unit
The hybrid inverter and battery modules come together in one integrated unit, with a tidy, compact installation.
Whole-home backup built in
The ESA can back up your whole home during a blackout, with no separate backup gateway needed.
Fast switchover
Designed to switch to battery power almost instantly, so most appliances keep running through an outage.
Expandable
Battery modules stack, and multiple units can be connected for larger homes, so you can add capacity later.
Built for outdoors
A weatherproof design suited to outdoor installation on a wall or in a garage.
LFP battery chemistry
Uses lithium iron phosphate (LFP) cells, a long-lasting and stable choice for homes.
Single-phase and three-phase
GoodWe options for every home
Single-phase
Most homes
The single-phase ESA suits most Australian homes, with whole-home backup built in and no separate gateway.
Three-phase
Larger homes and businesses
The three-phase ESA (approved for Australia in 2026) brings the same all-in-one design to three-phase homes and small businesses.

GoodWe FAQs
Can the GoodWe ESA power my whole home in a blackout?
Yes. Whole-home backup is built into the ESA, with no separate gateway. Very large loads may need to be managed during an outage, and we will explain this for your home.
Can I add a GoodWe ESA to my existing solar?
Usually, yes. The ESA includes its own hybrid inverter, so it typically replaces your existing solar inverter while keeping your panels. We'll check your system first.
Does the GoodWe ESA work with three-phase power?
Yes. GoodWe now offers a three-phase ESA alongside the single-phase model, so both single-phase and three-phase homes can have an all-in-one ESA system.
