HOW TO CALCULATE BATTERY BACK UP TIME CALCULATION” 1) House Load = 300WATTS 2) Battery volts = 12 V (given on battery) 3) Battery Capacity (AH) = 180 AH (given on battey). 4) FORMULA USE = Watts (W) ` = volt (V) X Ampere (A) = V X A Ampere (A) = watts (W) / Volts (V) 5) ACTUAL use Amepere (A) = 300 watts / 12 V Battery volts = 25 A 6) Battery Back up Time = Battery Capacity AH / Actual current USE (Ampere), 7) 180 AH Battery Capacity / 25 A actual use current = 7.20 HOURS Battery Back time 8) Note: Battery time also depands on Battery Age , Temperature and Load types
