If you’re weighing a battery for solar backup, time-of-use rates, or outages, compare usable capacity against the appliances you need to run. Enter appliance watts and backup hours to estimate battery size, sort essential from optional loads, and compare charging plans against your utility rate schedule. Leave with a sizing estimate, a backup-load plan, and questions to take to an installer.

Ways to start
A few requests this Agent can handle.
I want backup for a fridge using 180 watts, a 700-watt sump pump, and a few lights for 10 hours. What usable battery capacity should I consider?
My solar system is 8 kW, and my evening use is about 12 kWh. How should I estimate battery size and charging needs?
My utility charges 12 cents per kWh overnight and 32 cents from 4 to 9 p.m. What battery capacity would cover 8 kWh of evening use?
