About Off Grid RV Solar System

There are five components of the Off-Grid RV Solar System. The first component is RV solar panels. The second one is the charge controller. Third one is your battery bank. Fourth one is the inverter. Fifth and last one is the battery monitor.

Solar panel grabs the energy from the sun and convert it into electrical energy. Charge control then helps it maintaining the right amount of charge. The right amount of charge is then sent to the battery bank for storage. An inverter converts electricity from DC to AC. The battery monitor shows the stats about the battery.

These are the main five components of an Off-Grid RV Solar System. Managing and keeping the components the right way matters so much. At the time of installation, one must know the right number of batteries to be attached based on the usage of electric appliances In the RV. The batteries must be stored rightly and not so close.

The RV Solar System Wires Order:

The wire’s order is important. Spark or fire can occur if the wirings are not done correctly. The wiring must be done by a professional electrician or under the supervision of an electrician. Double-check all the wiring which are done. Following is the right order to do the wire connection.

The RV Solar System Wires Order

  1. First, connect the two 12V batteries through a series connection method, and then connect to the battery terminal of the Charge Controller.
  2. Connect four 18V solar panels in two strings and two parallel, and then connect them to the solar terminals of the Charge Controller.
  3. Finally, connect the Inverter to the Inverter line of the Charge Controller.

RV Solar System Working Principle:

The working of the solar systems in RVs is a really interesting procedure.

The sun hits on the surface of the solar panel placed on the top of the RV. The solar panel absorbs the sunlight. Thus the light energy is converted into electric energy. With the help of an inverter, light energy is converted into electric energy. Which is then stored in the battery.

The direct output voltage of solar energy is generally 12V, 24V, and 48V. Thus, to provide 110v electric energy for electric appliances in RV. The DC current is converted into AC current. If the consumption is much and more electricity is needed, then on some occasions multiple voltage load is required. For this, a DC-DC inverter is also used. Such as converting 24V electrical energy into 5V electrical energy. The converted electric energy can be used directly or stored in a battery for emergency needs.

How much solar power do I need for my RV?

Most people prefer at least having two solar panels on the roof of their RV. The RV needs at least 120 Watts to run basic electrical appliances. It is important to know a single solar panel is not enough for the RV.


This power is enough for very basic use. It will be enough if you want to use a table lamp, a radio, and a torch. Going for a 100W is a very reasonable choice if you don’t want to spend much money on solar panels and your requirements are very basic.


For this one must install two solar panels on the RVs Roof. This will provide power for a table lamp, a radio, a torch, and a table fan. 150W of energy is enough for basic requirements.


As the number of Watts increasing, the number of solar panels is also increasing. 200W is enough for normal use. This covers the power for a table lamp, a radio, a torch, a table fan, smartphone charging, laptop charging, and a small screen. 200W of energy is enough for the normal or moderate requirements.


An estimated thirteen small-sized solar panels are able to provide 300W energy for the RV. It is the right amount of energy to run electric appliances for a couple of hours. It can run a table lamp, radio, torch, table fan, mobile devices, laptop, screen, toaster, gaming console, DVD players, and many more devices.


400W is a pretty strong power supply. A small house can run by using 400W power. For RVs, this power is more than enough. Plus this power allows the dishwasher and vacuum cleaner to run in the RV. However, having 400W by using a solar power system is an expensive method.


15 to 30 solar panels are required to obtain 450W of energy. The number of solar panels truly depends on the quality and size of the solar panels placed on the top of the RV. It covers the whole roof of the RV with solar panels. It can run all the electric appliances for several hours. A large number of batteries are also required to store the energy obtained from solar panels.

C7 RV can be taken as an example

C7 RV is calculated according to the body length of 6 meters and the width of 2 meters. The overall area of the C7 RV roof is about 6 × 2 = 12 square meters.

It does not include the overhead forehead area, air conditioner outdoor unit, and overhead sunroof.

In addition, there is an extra space of 5 square meters left after the space occupied by the satellite antenna. That 5 square meter space is still available for installing additional solar panels. This totally depends on the electricity requirement of the user.
