How to wire solar panel to 12v battery.

The following solar panel wiring diagram shows that a 12v 120w pv panel is connected to the solar charge controller panel negative terminal of panel to the negative terminal of mppt charge controller and vice versa for positive terminal. When you have the proper guidelines on how to connect a solar panel to a 12 volt battery it will be easy to operate your solar cell. A solar panel is only going to deliver charge during the sunlit hours and when not in shade so let s assume that we chase the sun all day by moving the solar panel around and get 8 hours of sunlight. These can be an inverter 12 volts dc box or both.

So at 6 65 amps for 8 hours a 120w solar panel can potentially deliver 53 2ah of chargeback into our battery 6 65amps x 8hours 53 2ah. We will directly connect them to the charge controller battery and dc loads. Connect battery to charge controller in the first step you are going to wire the battery to a charge controller. Connect the panels of a solar bank together if there are more than one.

They are usually wired in parallel to preserve the voltage of each panel but you can also wire sets of them together in series to increase the voltage to conform to the voltage of the battery bank if need be. The following wiring diagram shows that the two 12v 10a 120w solar panels connected in parallel will charge the two 12v 100ah parallel connected batteries as well as power up the ac load through batteries and inverter during the day in normal sunshine. During shading night when there is no generating power from solar panels the battery stored energy will be used as a backup power and it.
