Hey you guys,
I measured with my "real" multimeter. When I switch my inverter/charger off, there is 0 load on the battery. Checked on both scales -- 20A and milliamp. Zero. And because I used the "calibrate to 0" function on the BMV-712, I now know it's giving me an accurate current indication. That's the good news.
The bad news: I was blown away by the load with the inverter switched on. When I'm inverting to feed the "parasitic" 110 volt loads, the draw is 1.5 - 1.6 amps. Since I wired the inverter to a dedicated sub-panel, I can get a fair idea of where the drains are by opening all breakers, then switching them each back on while looking at current flow.
It looks like the inverter is drawing 1.2 - 1.3 amps. The spec-sheet says 1.125 (.67 in power-saver mode). Not sure why I'm not seeing that. Could be the meter is just not accurate?
I've got separate circuits for 1) TV and powered recliners 2) Microwave 3) bedroom 4) GFCI. The first 3 all draw about .1 amps each. I still need to discover the particular devices that are resulting in these unexpected loads. The only load I expected was the Microwave's LED display, but .1 amps seems high for that -- to me.
Long story short, the way I wired it up, I now know that I *must* turn the inverter off before leaving the trailer unattended for any length of time.
