The main role of a controller is to protect and automate the charging of the battery.
Solar panel controller function.
It does this in several ways.
Solar charge controllers regulate the energy flowing from the pv array and transfer it directly to the batteries as a dc coupled system which is the most efficient and effective manner he said.
Open circuit voltage of a battery is a direct function of the specific gravity of the electrolyte at the place in the battery where the chemical.
This is important as overcharging the batteries can potentially ruin them.
I ordered a renogy 4 panel 400watt solar kit with the 40 amp controller.
The controller is designed for 12 24volt which is an automatic match for 0 600w for solar panels and 0 800w for wind turbines.
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.
Taking care that the battery bank is not getting overcharged during the day.
It regulates the voltage and current coming from the solar panels going to the battery.
This device has an mppt function that manages the system to work normally at low wind speed.
I am assuming that i do not need any fuses on the panels or between the panels and controller because the amperage and voltage will probably be well below the limits of the charger.
That s it this is my own explanation on how to set my own off grid solar charge controller.
The main purpose of the controller is to prevent the batteries from over charging.
The controller directly reads the battery level and once the battery is full it knows to slow down the rate of solar charge to a float keeping is from charging the batteries past 100.
Here are listed the main functions of the charge controller in a solar panels system.
Giving batteries as long of a life as possible is an important function of a charge controller.
I am going to wire in series parallel.

In this video ryan teaches you how to test your solar panels.
The charge controller connects the solar panel trough the storage battery it controls the power coming from the solar panel so that it will not overcharge the battery.
Without a controller between a solar panel and a battery the panel would overcharge the battery by generating too much voltage for the battery to process seriously damaging the battery.
Reducing the voltage of your solar panel.
