How to calculate battery power. Battery capacity is typically measured in Amp-hours Ah or milliamp-hours mAh although Watt-hours Wh is occasionally used. For example 24 kWh 500 amp hours at 48 volts 500 Ah x 48V 24 kWh. E V Q.

An AGM battery will likely not even take a charge to 1380 volts and if it does it wont stay there once the battery is placed on a load. Therefore each lamp will pull 41 amps each per hour. Input these numbers into their respective fields of the battery amp hour calculator.

The simplest formula is. For 9 lamps and 8 hours thats a total of 2952 amps pulled from a 12 volt battery. Because power is a function of voltage multiplied by current and both voltage and current doubled from their previous values the power will increase by a factor of 2 x 2 or 4.

This power is often expressed in Watt-hours the symbol Wh. There is one last wrench in this motor. Total battery capacity needed Ah the calculated battery capacity you need what as a result of the above data entered.

The total energy that could be stored in the solar battery E in Wh or kWh could be calculated as follows. 10 kWh per day. What size battery do I need.

Rate of discharge considerations. KWh x 080 x Peukerts Usable KWh Peukerts. If you know the watts go to Step A below.
