GoodWe ESA Battery

Yes, the GoodWe ESA is CEC-approved and fully eligible for the federal Cheaper Home Batteries Program. The battery system must have a nominal capacity between 5 and 100 kWh, and rebates are only applicable to the first 50kWh. We handle everything and provide the rebate as an upfront discount on your quote.

GoodWe ESA is manufactured in China. The company is headquartered in Suzhou, China, and has operated since 2010.

The ESA has a serious safety package, including six layers of battery protection, and integrated aerosol fire-extinguishing protection. Compatible hybrid systems also feature AI-driven AFCI 3.0 arc-fault protection, and integrated heating for colder operating conditions. The system is also IP66 rated, allowing an appropriately selected indoor or outdoor installation. As with any battery, correct siting, clearances, switchboard work and installation by an accredited professional remain essential - we will ensure all of this is covered when you get your GoodWe ESA installed with us.

Lithium Iron Phosphate (LFP), like pretty much every modern home battery. LFP is safer, more thermally stable, and lasts longer than older NMC chemistries. GoodWe publishes a cycle-life rating of at least 8,000 cycles for its listed 5 and 8 kWh modules and at least 10,000 cycles for its listed 6 and 9 kWh modules. That's roughly 5-27 years of daily use.

Yes. GoodWe offers three-phase ESA inverter options from 5 to 30 kW. The three-phase platform supports 5, 6, 8 and 9 kWh nominal battery modules and can reach 108 kWh nominal capacity across twelve 9 kWh modules. That places the largest ESA systems at the top end of residential storage and into small-commercial territory. Bear in mind that the maximum 108 kWh configuration is above the federal battery program’s 100 kWh nominal eligibility limit.

Yes, and the ESA is more flexible than most. You can add modules to an existing stack as your energy needs grow, mix old and new batteries in the same stack (rare), and mix the 5 kWh and 8 kWh module sizes. Single-phase scales to 48 kWh (6 modules per column), three-phase scales to 108 kWh (12 modules across two columns). We do recommend future-proofing and sizing correctly the first time, though, as this can save you a fair bit of money down the road.

Two warranties, actually. A 10-year product warranty (covering manufacturing defects) and a 10-year performance warranty. The performance side guarantees the battery will retain at least 70% of its usable energy at the 10-year mark, or deliver 3.65 MWh of throughput per usable kWh, whichever comes first.

Yes, it can support whole-home backup or essential circuit backup. Compatible single-phase ESA models provide an internal bypass of up to 63 A without requiring a separate backup gateway. Hybrid models can switch to backup in under 4 milliseconds, while the single-phase AC-coupled version is rated at under 10 milliseconds. Whether every circuit gets backed up depends on the inverter size, battery output, switchboard, air conditioners, pumps, ovens and other large loads in the home. Some properties are perfect candidates for full-home backup. For others, an essential-circuits design is the smarter and more reliable option. We work that out before installation rather than making a blanket promise.

Yes. The ESA comes in both hybrid (DC-coupled) and AC-coupled flavours. The hybrid version replaces your existing solar inverter; the AC-coupled version sits alongside your current system. Which one's right depends on whether this is a retrofit or new install with solar, and your storage goals. We'll work it out in your free quote.

It depends on the storage size you go with (anywhere from a single 5 kWh module up to 48 kWh single-phase, or 108 kWh on three-phase), the inverter, your existing solar, and your location. The ESA sits at an accessible price point relative to the rest of the residential battery market.
