10 kW battery per inverter. 5kW per battery, up to 2 per inverter.
The ARO is expensive, but for my desires it’s good choice. Once you wire it up, it’s hands off. It takes completely care of itself- none of the myriad of settings and close monitoring necessary with all of the lower end batteries. Also well contained in a enclosed cabinet safe for random people to wonder by - unlike a server rack.
It protects itself electrically and just works, my first one was 20 months ago and has been completely hands off, not a single hickup. 6 separate cabinets now, all will ever need. They should outlive me by a mile
