I have a MPPT 75/15 and I'm having issues with setting the load output. I select a user defined algorithm and set the low to 12.1v and the high to 12.8v (assuming that then Vbatt goes below 12.1v the load will shut off and when Vbatt goes above 12.8v it will turn back on). However, the next morning shortly after the MPPT turned on it shut off the load, it was 12.45v when the load turned off, Vbatt low in the log for the day is 12.44v. Why did the load go off?
I switched the high voltage to 12.4v (while battery is at 12.8v) and waited for the load to turn back on but it never did. I had to use AlwaysOn to switch the load (which has worked fine for the last few months). Am I misunderstanding how to use the load control?
