A solar charge controller is a device that regulates the flow of electricity from a solar panel array to a battery. It can automatically identify battery system and support multiple battery types, therefore, ensuring that the battery is not overcharged. It also prevents the battery from discharging back into the solar panel array. Solar charge controllers are used in off-grid solar systems, such as those used in remote cabins and RVs, and in grid-connected systems, such as those used in residential and commercial solar installations. MPPT tracking efficiency can reach up to 99.9% with fan cooling. A solar charge controller is attached with load overcurrent protection, short circuit protection, and overtemperature protection to keep user safe.
