To get number of Batteries, divide this value by your choice of 12V Battery size,

E.g if this value is  742AH and your choice of Battery size is 100AH 12V , then Number of 100AH Batteries is 742/100 = 8 Batteries. 

To get number of panes, divide this value by your choice of panel size,
E.g if this value is 2418 W and your solar panel choice is 250W 24V, then Number of 250W solar panels is 2418/250 = 10 Solar panels

This is the recommended minimum size of the Inverter. For solar systems, we recommend an equivalent hybrid inverter with built-in charge controller (PWM or MPPT).
