How Do You Wire A Solar Panel To A Battery

To wire two or more solar panels and batteries in parallel simply connect the positive terminal of solar panel or battery to the positive terminal of solar panel or battery and vise versa respectively as shown in the fig below.

How do you wire a solar panel to a battery.

Connect the negative wire of the solar panel to the negative terminal of the battery. Divide the wattage of the solar panel by the voltage of the battery to get the number of amps your charge connector needs to handle. Solar panels are wired in series when you connect the positive terminal of one panel to the negative terminal of another. To charge a battery with a solar panel connect a charge connector to the solar panel.

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. Step 1 connect the panels of a solar bank together if there are more than one. Connect the positive wire from the solar panel to a battery cable with a fusible link between the battery and the solar panel. When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same.

Then run wires from the battery to the charge connector making sure to match the positive and negative poles. This will help prevent a fire or battery explosion in the event of a short in the wiring. 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.
