Hi, Trying to figure out the system draw will require a shunt between the battery and ground. There is equipment that you can buy, like the Trimetric TM-2025-RV Battery Monitor System (about $150). Some of the members use Trimetric and like them. If you do not want to sink a lot of $$ into this monitor, you can use the
Inexpensive Battery Monitor -entry Level. This system can be wired up and mounted with your remote display. I added this one and it gives me a good idea as to where the battery sits. You can use one with a switch to monitor both the Wh going into and out of the battery. They are about $18 dollars on Amazon. Get the one with the 100Amp shunt. At the end of the day, I normally just look at the Morningstar remote and see where the battery sits, after an hour of resting. Normally about 12.8 volts.. Another good day!
Did you wire in the battery temperature sensor?
