# How do I calculate what size inverter I need?

Calculations for solar inverter sizing

Size of Inverter=Total Load+(1+Af) / Ie VA. Size of Inverter= 475+(1+20%) / 80% Size of Inverter= 712 VA.

Also Know, how many batteries do I need for a 2000 watt inverter? If you max out the inverter at 2000 watts, you are pulling 2000 watts /12 volts = 166.6 DC amps per hour. If you use a 200 amp 12 volt battery you would divide 200 amp battery / 166.6 amps = 1.2 hours of run time.
