We produce and supplement a good amount of solar charge regulators that play important role in prevention against overcharging and overvoltage, thus maintaining the battery performance. The most advantageous fact of a charge regulator is that it keeps the load ‘ON’ in 24 hours time. It is widely used in solar or wind power generator systems, off-grid home battery storage system etc. Our device owns an individual code representing its feature of electrical parameters. The rated capacity of our device in terms of voltage includes 12V, 24V, 48V and 10A, 20A, 30A, 40A, 45A, 50A in terms of current.
