They are usually wired in parallel to preserve the voltage of each panel but you can also wire sets of them together in series to increase the voltage to conform to the voltage of the battery bank if need be.
Connecting solar panels to battery bank.
We are taking our new home off the grid.
Here are a few of the terms that are important to know when solar charging two battery banks.
In the first step you are going to wire the battery to a charge controller.
Connect the panels of a solar bank together if there are more than one.
If we connect in series we could have 2 6 volt 800 amp hour giving us a 12 volt battery system with 800 amp hour capacity.
We need 768 amp hours for our 12 volt solar installation.
Connecting my off grid solar battery bank.
If we connect in parallel we could have two 12 volt 400 amp hour batteries giving us 800 amp hours but keeping our 12 volt system.
Connect battery to charge controller.
Solar charge controller keeps the solar panel from over charging your battery or batteries.
