OK folks, I am having issues with my transfer switch or a Gremlin is loose in my home. So with a little help from wiseacre, I was able to figure out how to set the setpoints for low and high voltage switch points and so I brought it home and hooked everything up and for a week I enjoyed suspiciously great battery performance. I decided to up the amount of power I was using in an attempt to get the battery voltage down enough to switch over to power and even when I ran a 400 watt ceramic heater for hours the battery voltage stayed above 12.8 volts. I was concerned that my solar panels were not outputting enough power but the reason for that is because the batteries we full. So I decided to wire up my larger inverter with blue tooth phone app and put an even bigger 1200 watt heater into the test now I have a phone I can easily control and measure the voltage and power and of course it was measuring the voltage but would not measure power....hmmmmm, so, I use the phone to turn off the inverter and the heater was still running. I double checked that the transfer switch was telling me that it was using the batteries. So I said screw it and I unplugged the house power and the heater turned off. So even though the transfer switch was telling me it was using battery power, it was using house power. I double and triple checked my wiring and it was fine. So I figure OK screw it, and I simply reversed the connections from house and inverter and that took care of the problem. It was reversed but it was now working. This morning I wake up and see that the battery has dropped down to 12.2 volts and the switch is telling me that the power is now coming from the house. Nope, it was still using the inverter power even though the switch is telling me house power. So....I reversed the house and inverter wires and am now back to normal operation. What the hell guys? Seriously, what in the hell is going on? Oh, and I do not have the set up grounded, just using line and neutral from both my wall and inverter outputs.
