BATTERIES
To achieve 50% cycling you should calculate your
To calculate
(AC Amps x 10) x 1.1 x hours of operation = DC
(AC watts/12) x 1.1 x hours of operation = DC
(AC VA/12) x 1.1 x hours of operation = DC
In all formulas, 1.1 is the factor for inverter efficiency.
Calculate the above for every AC appliance or tool you intend to use on your inverter. This will give you the total number of
