Solar Car Battery Charger With Charge Controller

Trickle charge your 12v battery and extend battery life no electricity needed.

Solar car battery charger with charge controller.

Mppt maximum power point tracking and pwm pulse width modulation. 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. The main function of a charge controller or regulator is to protect your battery from excess current and voltage. They are made to charge regular car batteries and can also power any 12 volt devices.

There are 2 main types of charge controllers. It s important to use a charge controller as it improves the efficiency of a solar powered system by up to 50 can prevent the batteries from being overcharged and will extend the battery s life when used correctly. That also means the less time the charger has to be out in the open cutting down on times it can be damaged by weather or something similar. In the simplest of terms a solar charge controller regulates the power that is transferring from a solar panel to a battery.

What makes a good solar car battery charger efficiency the more efficient a solar charger is the more light energy will be transferred into battery energy. 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.

2 4w solar charger harness the power of the sun with the schumacher sp 200 2 4w 12v solar battery maintainer. If the system continues to apply a charge the battery voltage and temperature rises. When a battery reaches full charge it can no longer store incoming energy. Solar charge controllers also prevent battery drainage by shutting down the system if stored power falls below 50 percent capacity.
