Calculate total Watt-hours per day needed from the PV modules. Multiply
the total appliances Watt-hours per day times 1.3 (the energy lost in the
system) to get the total Watt-hours per day which must be provided by the
panels.

INVERTER SIZING
choose an inverter that is much larger
TOTAL WATTAGE: 220 than the computed load (Watts)

REMARKS:

The inverter must have the same nominal voltage as your battery.
For stand-alone systems, the inverter must be large enough to handle the total amount o
you will be using at one time. The inverter size should be 25-30% bigger than total Watt
