A solar charge controlleris a device which is placed between a solar panel and a battery. It regulates the voltage and current coming from your solar panels. It is used to maintain the proper charging voltage on the batteries. As the input voltage from the solar panel rises, the charge controller regulates the charge to the batteries preventing any over charging. Usually, the solar power systems uses 12 volt batteries, however, solar panels can deliver far more voltage than is required to charge the batteries. In essence, converting the excess voltage into amps, the charge voltage can be kept at an optimal level while the time required to fully charge the batteries is reduced. This allows the solar power system to operate optimally at all times. We have PWM and IP 68 MPPT solar charge controllerrange from 5A to 60A for 24 hours solar system or solar street light. Customers could choose suitable model according to detailed demand. For example, calcualte the load working power one day to chooose the suitable panel power and battery capacity. Then choose the right solar controller.
Advances in off grid solar system technology means it’s now cheaper and more efficient than ever to start living off the grid with electricity generated by stand alone solar and battery power. If you don’t have access to the grid for power, then an off grid solar system is a great solution as a stand alone power system or complete energy system for your home, shed, boat, granny flat, remote/rural property or any other off grid application.
