EcoRenovator - View Single Post - 2 Charge controllers on same battery bank!?

That's sort of what I was thinking.

What if I just left the solar charge controller connected and simply UNPLUGGED the UPS from wall power when I wanted to exclusively use solar?

Then the UPS isn't charging the batteries, the voltage is lower, and the solar sends power to the batts.

If I want, at night, I could just plug the UPS back in.

Granted, it's manual, but there are plenty of times that I might want several days of solar, and then just use the UPS to top the batteries off.
