Choose your GoodWe ESA capacity
All five packages use the same 9.99kW single-phase ESA platform. Choose storage around your evening consumption, solar surplus, backup expectations and likely future loads—not simply the largest number.
| Capacity | Battery modules | Normal price | Sale price | Good starting point for |

| 16kWh | 2 × 8kWh | $9,790 | Efficient and moderate-use homes wanting meaningful overnight storage. | |
| 24kWh | 3 × 8kWh | $12,490 | Medium homes with stronger evening loads and more solar to retain. | |
| 32kWh | 4 × 8kWh | $14,990 | Larger households seeking substantial overnight coverage and backup runtime. | |
| 40kWh | 5 × 8kWh | $17,790 | High-use homes with EV charging, pool equipment or heavy evening demand. | |

Why consider the GoodWe ESA platform?
One coordinated ecosystem
Hybrid inverter, battery management, storage and monitoring are designed to operate together rather than being assembled from unrelated brands.
Useful 8kWh capacity steps
The family runs from 16kWh to 48kWh in clear 8kWh increments, making it easier to match the system to real household consumption.
SEMS monitoring
GoodWe’s SEMS app and portal provide a central view of solar production, household consumption, battery operation and grid exchange.
Backup without vague promises
The ESA can form part of a backup-capable design, but backup performance depends on the switchboard, essential circuits, starting currents and the loads expected to operate together. Pumps, air conditioners, compressors and other inductive loads must be assessed before whole-home or extended backup is promised.

Frequently asked questions
Is 48kWh the usable battery capacity?
Yes. This package is based on 6 × 8kWh usable GoodWe battery modules, providing 48kWh total usable storage.
Does the sale price cover every installation?
No. It is an installed-from offer for a suitable standard on-grid site. Backup design, switchboard work, difficult access, long cable runs, travel and other non-standard requirements are confirmed in writing.
Can it back up the whole home?
Potentially, but only after the actual loads, phase, switchboard and starting currents have been assessed. A large battery does not by itself guarantee that every appliance can operate together during a blackout.
Why is the inverter described as 9.99kW?
9.99kW is the package’s listed GoodWe ESA single-phase inverter rating. It is commonly described as approximately 10kW.
