GoodWe ESA Series
The ESA Series is an all-in-one solar and battery system. The inverter sits in the top module and your battery modules stack underneath it. You can start at the size your home needs today, and add more when that changes.

Why we fit the ESA

Arrives as one stack
Inverter, battery and backup switching come pre-wired, so one unit goes on your wall.
Add to it later
Your next module drops onto the one below it on a die-cast frame, and a blind-mate connector makes the electrical join as it lands.
Your home stays on
When the grid goes down, your home moves onto the battery in under 4 ms, through a 63 A bypass inside the unit.Sized to your home
What your home draws overnight decides the size of your battery. That number moves as your home does. An EV in the driveway, a heat pump, one more person home during the day. The ESA can follow it.

Sized in 8 kWh steps, from two modules to six.
Every battery module holds 8 kWh usable, and a column takes up to six of them. We size yours to what your home actually draws overnight.
Adding an EV or a heat pump? Add a module underneath.
A column takes more modules, up to 48 kWh. An electric car or a flat in the back yard is one more module below the ones already there. Same system, and nothing new beside it on your wall. Ask for a quote and we'll size it against what your home actually uses.
Watch the ESA at work
GoodWe's own film of the ESA. Solar on the roof, the stack in the garage, the grid dropping out and the power staying on.
Solar battery rebate
See how the Cheaper Home Batteries discount applies to four GoodWe stacks. An accredited retailer takes any eligible discount off your purchase price on the day, so there is no separate claim afterwards. The discount per kWh reduces as your storage capacity increases, and the rate steps down every six months until 2030.

GoodWe ESA specs, single phase and three phase
The single phase GoodWe ESA Series is an all-in-one solar and battery system. The inverter sits in the top module, and 8.0 kWh usable battery modules go underneath it, up to 48 kWh in one column. Backup runs through a 63 A bypass inside the unit, so no gateway is mounted beside it on your wall, and the changeover measures under 4 ms. The three phase ESA is the same idea on a three phase supply. It runs 5 to 30 kVA, takes the same 8.0 kWh module, and accepts up to 60 kW of DC solar. All capacity figures on this page are usable capacity.
