We get asked all the time which battery someone should be putting in.
Price per kilowatt-hour is the easy answer. It's rarely the right one.
Here's why Goodwe ESA keeps coming up. It's modular, it grows with you, and it takes fire safety to another level.
Start there, because it's the part nobody thinks to ask about. AI thermal monitoring, aerogel insulation, smoke and gas sensors, and an aerosol extinguisher built into every individual battery pack, not just the cabinet around them. Protection that acts, not protection that only contains.
The battery is built in layers, so when your usage changes you add another module to the stack that's already there. No second system, no more wall space.
The PV inverter sits in that same stack, which matters more than it sounds. Normally that's a separate box doing its own thing next to the battery. Here it's one unit, one app, one company to call, and solar charges the battery directly instead of being converted twice.
There's a slot for an EV charger when you want one, and it makes for a tidier install: fewer boxes, fewer conduits, fewer joints sitting out in the weather.
Add optional full three-phase backup and the whole house rides through an outage, not just a couple of circuits.
Work out the sizing. That's the part we'll help with.
