However the same 40a charge controller used with a 48v battery can be used with a much larger solar array up to 2080w.
Battery charge controller solar panel.
Solar charge controllers also prevent battery drainage by shutting down the system if stored power falls below 50 percent capacity.
The charge process is performed in a smart or intelligent way.
A charge controller or charge regulator is basically a voltage and or current regulator to keep batteries from overcharging.
Most 12 volt panels put out about 16 to 20 volts so if there is no regulation the batteries will be damaged from overcharging.
This involves varying charge stages voltages and current depending on the type of battery and other factors.
This helps preserve the life and health.
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.
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.
The charge controller closely monitors the battery voltage and automatically reduces the flow of energy to the battery bank.
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 charge controller is designed to receive power from a solar panel or array of panels and use it to charge a battery or bank of batteries.
If you connect your solar array to batteries without overcharge protection you could compromise the life of your batteries.
