Minimum Battery Bank

0
Ampere Hours (AH)

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.

Minimum PV System Size

0
Watts

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

Recommended Inverter

0
Watts (W)

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).
