Battery Charge Controller Solar Panel

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

Battery charge controller solar panel.

There are 2 main types of charge controllers. Both will regulate the maximum voltage that the solar panel can send to the battery but an mppt charge controller can be up to 30 more effective at storing and transferring energy than pwm models. Mppt maximum power point tracking and pwm pulse width modulation. Solar charge controllers also prevent battery drainage by shutting down the system if stored power falls below 50 percent capacity.

The solar charge controller sits between the solar panels and battery bank and prevents overcharging of batteries by limiting the amount and rate of charge to your batteries. It regulates the voltage and current coming from the solar panels going to the battery. Solar panel charge controllers are an essential part of your off grid system. Free shipping by amazon.

Too much charge can lead to overheating a rapid loss of water and an excess release of hydrogen gases which can build up ignite and cause an explosion. Generally a fully discharged 12 volt 100ah battery needs 1200 watts of energy to be 100 recharged.
