How much capacity does this kit have?

The station starts at 3.84kWh, and the included expansion battery raises that. Adding more batteries takes it to a maximum of 26.9kWh.

Can it run a whole house?

It delivers 6,000W of AC output at 120V and 240V, expandable to 12,000W with a second unit. That covers critical circuits through a transfer switch, not every load at once.

How does it charge from a gas generator?

It accepts a 240V gas generator and passes up to 6,000W through a bypass, so you can run loads and recharge during long outages.

What solar array can it take?

Up to 3,200W of solar input through two MPPT controllers that accept 11-165V each.

Can it charge an EV or RV?

Yes. It has NEMA TT-30P and L14-30 ports for direct EV and RV charging.

How long do the batteries last?

The LFP cells are rated for 10+ years of use, and the station carries a 5-year warranty.
