Charging RV batteries – use solar panel in 7 easy steps
Solar panels have been the sensational appeal to the world of charge and power and what can be a better way to conventionally charge RV batteries? With about $600-750 investment on some tools and supplies, you can meet most of the basic requirements of power. We will be discussing the basic steps to make a rechargeable setup of RV batteries with solar panels.
Step 1: Setting up the batteries
Once you get the batteries, connect to a charger and charge it up. Well, you may have a new battery but it is never all full charge. New batteries may only be filled up to 60% of their capacity. After you charge it through the charger for some time, it will confirm that the batter is filled to full capacity and can now be used to set up the system.
Step 2: Setting up the solar panels
The next thing you need to do is set up the panels. It may take some time for your battery to reach full capacity. This gives you time to complete this step in the meantime. All you need to do is arrange the solar panels and wire them up for connectivity. It will save up time later and get you instant access to charging your RV battery. Wait for the battery to charge up after you are done with the solar panel setup and you are ready to start with.
Step 3: Placement of the batteries
After charging you are required to arrange the batteries in a container. Ensure that the arrangement has the entire positive (+) and the negative (-) terminals arranged in a unidirectional pattern. You need to measure the distance in between the terminals to prepare the jumpers.
Step 4: Preparation for the jumpers
You need to create some jumpers to make the parallel connection between the batteries. The size of the cable must be dependent on the power of the inverter. For a 1200 watts/12 volts setup giving out 100 Amps, one 2 AWG cable can do the job. For a system that generates 200 Amp current use 2 cables. Cut the cable as per the measured length and fix it to the mechanical lugs.
Step 5: Lid preparation
To run the inverter and the charging controller wires, you need to make some holes with a drill or any means on the lid. You can either have the charge controller concealed in the container or have it outside. Make sure the holes are not too big or not too small for the wires.
Step 6: Connection of the batteries to inverter and charge controller
For the penultimate step, you are required to connect the batteries to the inverter along with the charge controller. Do not forget to check two things. Confirm that the charge controller is not connected to the solar panels. The inverter should be turned off as well. Make the connections and secure them with holders and tape.
Step 7: Getting done with the final setup and testing the system
After you are done with all of the above steps, all that is left to be done is connecting the solar panels to the charge controller and turning on the inverter. Do it and the setup is complete. Check to confirm the system is working.
Depending on how you are planning to use this RV battery, you can select the size for your battery. While the setup is not that cheap, it can serve the purpose and the worth.
