Oh No ! I bought a Mppt Solar Controller
I don't believe it ! I bought it and I don't really even want it ! I was sure this would go for more than 12 bucks. Fooled me, oh well. Whats w/ links not working ?

Here is the efficiency chart for the Rogue 3024 along with a quote from the manual.
"Typical efficiencies range from 95-97% under most conditions. As a rule of thumb, higher efficiency occurs as PV voltage increases (which causes a corresponding decrease in current for a given amount of power), and as the difference between PV and battery voltage decreases."
I'm at the beginning of learning curve yet, but from the voltage on display it looks like you are running very high loads at this moment. I am not sure whether Rogue manual meant the battery voltage in absence of loads - which is not the case here - or "any" battery voltage.
It says PV voltage so it's talking about the panel or input voltage. The first two examples were heavy load with high battery SOC. The last example was after several days of lousy weather and the bank was lower so it was mostly charging battery. I don't think the controller can/does differentiate between output used for battery charging or other load. A load is a load.
