Buy backup power by the numbers.
Compare capacity, inverter output, solar input, warranty and battery-cycle claims—and use federal outage and electricity-price data to understand reliability and recharge cost.
Backup power is an engineering decision.
Watt-hours determine runtime. Inverter watts determine simultaneous load. Recharge power determines whether your system can recover during a long outage.
