Motorhome Solar Panel Wiring

Once you have planned out the routing of the cables the wiring of a solar panel is a fairly simple task.

Motorhome solar panel wiring.

You will likely need to purchase a battery inverter fuses and wires separately. So if you wire together a 100 watt solar panel and a 175 watt solar panel in parallel you ll get a total of 275 watts. To lead the cable securely through the roof of your motorhome use a sunworks roof cable gland. The first step in installing a solar kit is mounting your rv panels.

Wiring rv solar panels in parallel. If we have two solar panels with same voltage and power the connection will be very simple. Romex cable comes with multiple conductors encased in a second insulated covering. For my installation of rv solar panels 10 gauge household romex wiring was chosen for a few reasons.

This is easily done using sunworks pvc solar panel mounts. The connection to your battery must be fused correctly. When you hook multiple solar panels together you must observe these limitations as too much current will create heat insulation could melt and a short could cause a fire. This prewired for solar rv included the installed charge controller but it did not have any solar panels installed from the factory.

Solid wire passes electricity at a capacity 1 size greater than stranded wire. In some of the newer instances that use this form of wiring the charge controller is already present the only piece that needs to be added is the solar panels themselves. That means if you wire panels with different wattages the overall outcome won t be affected. As clearly visible in the picture it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one.

From the solar panel i connected the cables to the inlet of the double pole switch then 2 short red and black cables from the outlet of the switch to the panel connections on the solar charge controller. Wiring your solar panels in parallel increases the amperage while keeping the voltage the same. The process will differ depending on what type of panels you have. Wiring tips for your rv solar power system.

Each size of wire has a different current rating. That means the 10 gauge wire works as if i had used 8 gauge automotive wire. Rigid panels typically must be affixed to the roof with screws. You must allow a small gap underneath the solar panel to allow air to circulate.
