I installed the 712 and it appears to be working fine. The only thing is, when I am hooked to shore power, or my engine is running, my ah and watts still show negative numbers. I flipped the shunt and the numbers displayed were only positive regardless of weather or not I was on shore power, and the battery never dropped below 100%.
I have since switched the shunt back as per the install instructions. Cant figure out why the numbers are negative while charging.
My settings are:
Battery Capacity :148 Ah
Charged Voltage: 13.2
Tail Current: 2.00%
Charged detection time: 3m
Peukert exponent: 1.25
Charge efficiency factor: 95%
Current Threshold: 0.10A
Time-to-go av period: 3m
