Solar Controller Battery Draw Amount?
This is a confused sort of post because I am confused. I was trying to get to the minimum amps for knowing when my AGMs were truly full and to do that I tried to get all the other draws down to ne...

Like many solar controllers, no doubt many inverter/chargers need to initially draw power from the battery to power up their control circuits and become operational. But, once they start charging (using either solar or AC power input), they're powering themselves, and what's left goes to the battery.
I probably got what Doug said confused too. Here is what he said:
"..... Inverter/Chargers supply power TO THE BATTERIES, then the batteries supply power to the RV 12 volt systems. ........"
And, as long as everything is wired through the shunt as it should be, the Trimetric will only see what's actually going into/out of the battery. It doesn't know or care about anything connected to the "load" side of the shunt.
Again, what size is your inverter?
