Small Solar Panel Charge Controller

Most 12 volt panels put out about 16 to 20 volts so if there is no regulation the batteries will be damaged from overcharging.

Small solar panel charge controller. The safest way to figure out if you need a charge controller is to take battery amp hour capacity and divide this by the solar panel max. It protect the battery from being over charged by the solar modules and over discharged by the loads. And if you need batteries you ll need a charge controller. Maximizing the energy from solar panels to charge your system.

It regulates the voltage and current coming from the solar panels going to the battery. If the number is less than 200 than you need a controller. If you are looking for a low cost solar charge controller for your small solar system we highly recommend the allpowers pwm controller. With a max input voltage of just 50v and current input limit of 20a it s far from some of the powerful mppt systems available online.

It is a device which most importantly properly charges a battery or battery bank enabling as long a life as possible. We categorize charge controllers based on amp size. The charge process is performed in a smart or intelligent way. Yes charge controllers are a critical part of solar installations.
