Depending on the time of use when power cut off long or short that we choose the capacity of battery by the following formula:
Battery Capacity(Ah) = P(Power Consumption-Watts) x T (Operating time - h) / 0.7 (using coefficient) x U (Voltage of the battery-volt)
Assuming you use a machine with DC voltage is 24V and the power you need to work in 5 hours is 1KW: Battery capacity is 1000x5/0.7x24 = 297.61 Ah (equivalent to 4 accu 12V/150Ah)
Note:
- The formula is calculated for the ensure quality battery.
- The maximum let out curent of battery’s not more than 3 times the amount of battery operating time in this mode is not more than 3 minutes continuously. It is usually choosed to battery capacity to work 2 hours or more.
