Battery Charge Controller Solar Panel

If you connect your solar array to batteries without overcharge protection you could compromise the life of your batteries.

Battery charge controller solar panel.

As listed below a 40a solar charge controller used on a 12v battery can be used with a maximum 520w solar array. A solar charge controller is a component that helps manage the power that is going into the battery store from the solar panel. A solar panel battery charger is a device contains a photovoltaic solar panels solar charge controller and a solar battery generally portable that allows the photovoltaic solar energy to be converted into electrical energy that can be used by many electrical devices. 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.

It safeguards the deep cycle batteries from being overcharged during the day. This helps preserve the life and health. 20a solar charge controller 50ah 150ah battery 12v 20a 100v mppt 12v battery 250w max solar 1 x 250w. Solar charge controllers also prevent battery drainage by shutting down the system if stored power falls below 50 percent capacity.

Also you can use mppt charge controllers with strings of solar panels but not pwm controllers. A charge controller or charge regulator is basically a voltage and or current regulator to keep batteries from overcharging. 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. However the same 40a charge controller used with a 48v battery can be used with a much larger solar array up to 2080w.

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