I have a simple 80W solar
system setup, and I have determined that there is something draining my battery
when it is hooked up and not in use. It has killed a lead acid battery
and drained a lithium iron one down pretty low before I was able to recharge it. And I do have diodes attached in line with the solar panels
to prevent the battery from draining back into them. But, I'm not really sure what is going on with the panels
when there is very little sunlight, and the SunSaver says it is charging
, but the voltage from the panels
is too low.
So, I have looked into how I can use solid state relays to disconnect the solar panels
when they aren't producing power above 10V using this solid state relay

I'm not sure if my SunSaver would do this if I hooked it up to the load terminals though? It will disconnect loads if the battery voltage goes below 10.5 or something. So in the picture, the one for the inverter
won't be needed.
Are there any obvious flaws to this idea that you can see?
