How To Connect Multiple Solar Panels To Battery

Parallel connection of two identical solar panels.

How to connect multiple solar panels to battery.

The wedgetail camper has two solar inputs via red anderson plugs. Connect the negative wire of the solar panel to the negative terminal of the battery. I spoke to the people at wedgetail campers about how the two solar inputs were wired. 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.

To meet high power charging requirements several solar controllers can be connected in parallel to a battery bank with each controller connected to its own separate pv subarray. Following this example where there are two 12v 200ah batteries connected in series we will have a total voltage of 24v volts and an unchanged capacity of 200ah ampere hour. The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected. In off grid wind and solar power systems the greater the direct voltage for charging the batteries the lesser energy is lost along the cables.

If we have two solar panels with same voltage and power the connection will be very simple. The first is on the roof. To wire solar panels together for charging a battery connect the panels in a parallel circuit. The same voltage of 13 8 from the charge controller can charge all the battery connected in parallel.

There are 3 ways to connect solar panels. How to connect two solar panels to one battery it s all in the wiring. Same applies to two or more solar panels. In the event you have more than one battery connect them in parallel.

Large off grid solar and battery backup pv systems often require greater charging than a single controller can provide. Parallel series and a combination of parallel and series.
