100 ah 5 hrs 20a this means charging your battery at 12v and 20a will take 5 hrs to fully charge a 100ah battery 20a x 12v 240 watts.
Simple formula for solar panel charging.
There are 3 sets of terminals.
There are many different types of solar regulators the ones i would recommend sit as a central controller in the system.

For example if your solar panel is 300w and you want to charge a 12v battery you d divide 300 by 12 to get 25 amps.

You can use an electric fence charger for the outside of your solar facility.
In that case you d get a charge controller rated for 30 amps.
Alternatively you may choose to purchase a pre configured solar panel kit.

If you are trying to set up a solar panel system that can provide enough energy to fuel your electric car you will need this type of setup.
Input from solar panels.
Solar kits normally come with solar panels a charge controller and z brackets for mounting.
The combination of a solar panel system and ev charging station brings several benefits and provides a cost effective way to produce and make use of your solar energy.
Solar panel and ev charging system.
If we assume a roughly ten hour daily optimal sunshine the specifications for the solar panel could be simply and quickly calculated as explained in the following expression.
It is responsible for taking the fluctuating power from the solar panels and converting it into usable power both for direct use and for charging the battery bank.
To counteract overcharging a battery pack the charging current must not be greater than one tenth its amp hr capacity.
When the wattage of your 18v panel is 10watts the current is 10 18 0 55 amps 550ma.
In particular a 2 000mahr group of cells must not be charged at a level beyond 200ma for 14 hours.
