Your ideal solar charge controller in any case must first have sufficient capacity to handle the amount of voltage and current produced by your RV’s solar system. While a solar charge controller might have a voltage rating of anywhere between 6 and 60 volts, the most common ratings are 12 volts, 24 volts and 48 volts.
Dry camp/ Shore power switch: Some RV solar charge controllers have a special switch to change the battery’s charging voltage points between maximum power during off-grid trips and standby mode when you are plugged into shore power at a campground.
Set the absorption charge voltage, low voltage cutoff value, and float charge voltage according to your battery’s user manual. Adjusting these settings helps prevent battery damage and promotes efficient charging. Start Charging: Your solar charge controller is ready to go once all these settings are adjusted!
A solar charge controller can handle different battery voltages, usually between 12 volts and 72 volts. The standard settings are made for either a 12-volt or a 24-volt maximum input. Before using your charge controller, make sure to set the voltage and current correctly by adjusting the voltage settings.
A typical solar charge controller can provide a charge between 10 and 90 amperes to the battery banks. Larger solar systems would require larger charge controllers, so if your system expands, you might need to upgrade to a charge controller with a higher capacity.
A charge controller is needed to convert this energy into usable electricity, as well as distributing the current and voltage supplied by your solar system in the most productive way. This way, the best RV solar charge controller allows you to get the most available power while maximizing your battery health and lifespan.
