Yes, the shunt is quite stable where it is, due to the heavy cable up to the negative post of the battery. The two heavy black lines on the left side also stabilize it. One of those goes to the 1000 watt inverter, the other to the 12 volt
(yes 12 volt) microwave I have in the rig.
At this point I have no reason to go to a Tri Metric unit. On an all solar system where you are totally dependent on batteries for a long time period, and only have solar to recharge, I think they make sense, but in my opinion, they are not necessary on the RV system.
BTW, this meter also measures the charge from my small solar system I have on the Argosy, (about 3 to 4 amps) and in addition, it tells me the charge from the TV into the batteries. On a morning when the batteries have been run down from overnight furnace and lights use, I find my TV charge current, on startup, runs about 6 amps. That is not especially great, but I expect it is similar to what a lot of AS/TV combinations run, due to the long distance from the TV alternator combined with the resistance of the TV plug and all other connections involved.
My biggest draw is the 12 volt microwave, which takes close to 60 amps when I use it. I would never buy another, I think an inverter running a small regular 120 volt household unit would be a much better setup. Live and learn. Even at 60 amps, it is a very slow microwave.
