Voltage In Parallel Vs Series. Since a parallel connection will compound the amperage of a battery and a series connection will compound the voltage of a battery we can arrange cells in combinations of series and parallel to achieve our desired voltage and amperage. Since the two 5a 40v series strings are then wired in parallel we add the amps while not changing the volts because parallel wired solar panels or series strings get their amps added while their volts remain the same.
Another difference in a series circuit vs a parallel circuit is that in a parallel circuit the voltage across all legs of the circuit is the same. Since the two 5a 40v series strings are then wired in parallel we add the amps while not changing the volts because parallel wired solar panels or series strings get their amps added while their volts remain the same. In contrast batteries connected in a parallel configuration are able to increase the amp hour capacity of your batteries at the same voltage.
And the more work you have a series circuit do the more your current will decrease.
Returning to our 12 volt example. Using our same example of 5 panels each rated at 12 volts and 5 amps if you connected them in parallel you d still have 12 volts but now 25 amps. For example if i hooked up 5 20 amp circuit breakers in parallel would it take 100 amps to trigger them all. Parallel circuits are a bit trickier allowing multiple circuits to connect while operating individually as part of a larger circuit.
