How to calculate battery capacity for solar panels?

Calculation of battery capacity for solar panels. The minimum reserve of battery capacity, at night. For example, i f 3 kW*h of energy is consumed at night, then the batteries must have su ch a reserve of energy. If the battery is 12 volts 150 A h, then the ene rgy in it will f it 12 * 150=1800 watts (1.8 kW).

How do I use the energy consumption calculator?

Select an appliance from the list or enter one manually. If you select an appliance from the list, the calculator will estimate the power usage of the chosen appliance, and if the appliance operates on a duty cycle, the calculator will take that into consideration when calculating its energy consumption.

What is the global capacity of 2 batteries in series?

The global capacity in Wh is the same for 2 batteries in serie or two batteries in parallel but when we speak in Ah or mAh it could be confusing. - 2 batteries of 1000 mAh,1.5 V in series will have a global voltage of 3V and a current of 1000 mA if they are discharged in one hour.

How to get voltage of a battery in a series?

To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
