an easier option

yep give it all the dreaming and research to find the easiest way...

my circuit is in parallel , after the sun goes down, i can put the battery wiring from one solar charge controller from the main battery onto the spare battery with the 1000watt inverter

without wiring another inverter trying to think this through

...you know, need all i can get, with the electricity production....after a while of using the back up battery at night, the main batteries voltage might go up, and then it can work more efficiently.

an air filter in the yard is good thing, keep that system in, no matter how out of habit you are.

left alone the system is good, as long as the wires don't fall out or off,

more panels and i'll have to be attentive, it's good though these working hobbies are great

anyway see how good that works when i get another panel in.
