Battery Charge Controller Solar Panel

For example your solar panel delivers 18 volts dc and 5 8 amps to the charge controller and the wire length is 40 feet.

Also you can use mppt charge controllers with strings of solar panels but not pwm controllers. This helps preserve the life and health. A solar charge controller is a component that helps manage the power that is going into the battery store from the solar panel. 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.

Voltage drop in a single panel system as you can see in the calculation the voltage drop is 4 09 which will reduce the overall power delivered to the charge controller. A charge controller or charge regulator is basically a voltage and or current regulator to keep batteries from overcharging. However the same 40a charge controller used with a 48v battery can be used with a much larger solar array up to 2080w.

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. Solar charge controllers also prevent battery drainage by shutting down the system if stored power falls below 50 percent capacity. Most 12 volt panels put out about 16 to 20 volts so if there is no regulation the batteries will be damaged from overcharging.

It regulates the voltage and current coming from the solar panels going to the battery. If you connect your solar array to batteries without overcharge protection you could compromise the life of your batteries. As listed below a 40a solar charge controller used on a 12v battery can be used with a maximum 520w solar array. The charge controller closely monitors the battery voltage and automatically reduces the flow of energy to the battery bank.
