1. Due to the limited installation area of solar panels at the top of RVs, camper, caravan , solar controllers are required to have higher charging efficiency. solar controllers used in RVs are MPPT controllers, which can effectively improve the charging efficiency of 10-30%.

       2. The solar panel controller of the RV has the function of charging two batteries at the same time. One is the living battery and the other is the car starting battery. The car starting battery is usually charged with a small current, and the living battery is charged with a large current.

       3. In order to see the charging status in a timely manner, an external monitor is usually connected to it.

       4. At present, there are two kinds of living batteries on the RV: lead-acid battery and lithium battery, so the controller is preferably compatible with both batteries at the same time.
