How Much Solar Panel To Charge 4 Batteries In Series

So you could use a solar module that has a vmp of 26 28v.

How much solar panel to charge 4 batteries in series. A single solar panel of 280 watts will do the work for you. Then add 10 of the charging time. Charging time 40 hours 10 of 40. You generally want to have the vmp of the solar panels 10 20 higher than the battery voltage.

You should use a charge controller to protect the equipment. If you connect the four 6 volt batteries in series then its like one 24 volt battery. This is less than ideal due to the wasted energy. The next step involved in sizing your system and also in determining how to calculate solar panel battery and inverter is to size your charge controller but before then we have to understand some components which you probably have not encountered and so do not understand this will give you a better understanding of the calculation.

So you need 1200 250 4 8 hours of bright sunlight. If you have a 50 volt and 10 amp current coming from your solar panels but only want 15 volts the pnw charge controller will send a 15 volt 10 amp current into your battery.
