Battery monitor comments

My wife ordered this meter for me recently.

I've been talking about getting something like this for quite a while and she just decided to pull the trigger for me. Figured I'd offer some thoughts here in the event it helps someone else out.

Installation was very easy - once I decided where I wanted to mount it, that is. Ideally, I would like to have mounted it next to the factory meter on the bulkhead. But the thought of trying to fish 4 small wires down thru that very small and tight space was enough to make me put it elsewhere. Eventually, I decided to mount it very near the floor just below the door to the bathroom. Proximity to the batteries was very close which made running wires super easy. I installed the shunt just outside the battery box accessible via one of the factory exterior doors. Once a location was finalized, I had the wiring completed in about 45min.

The meter works exactly as advertised. I am now able to monitor and precisely determine how much juice is being consumed at any one time. This obviously means I can determine the exact amount of power each of my loads draw. Here are some of my observations so far (for those that are curious) on my AF811.

All lights and appliances off, LPG detector on, battery monitor running: .40 amp

Refer on, propane: .2 amp
Furnace: 3.7 amp

Stock florescent bulb over sink: 2.5 amp
Over-dinette dual LEDs: .4 amp
Over-dinette single LED: .2 amp

Hood fan, high: 1.3 amp
Hood fan, low: .6 amp

Fantastic fan, low: 1.0 amp
Fantastic fan, medium: 1.3 amp
Fantastic fan, high: 1.7 amp

Bathroom exhaust fan: 1.4 amp

Water pump: 5-6 amps

Raising camper with all 4 electric jacks: ~45 amp
Lowering camper with all 4 electric jacks: ~16 amp

The monitor does NOT show total cumulative amp-hours used -- that's my one big complaint. It does, however, show total cumulative power used (in Watt-hours). So with a little bit of arithmetic, I can easily calculate amp-hours. So not a huge deal there.

Being able to monitor my power like this will be very, very nice. We ALWAYS boondock when we're camping. And some of our trips can be 4, 5, or 6 nights. I have 3 young kiddos so we run the furnace at night -- just enough to keep it around 50-60 degrees inside. BTW, I have dual 6V Trojan T-105's in my camper.
