Help me choose a fuse and shunt
Four 6v golf cart batteries connected together with 2AWG wire, then 4/0 wire used to connect to the inverter posts. Inverter posts also connect to PD9270 converter/charger. According to wiring gui...

Okay, going through the key drivers here.
1. Inverter is by far the largest potential user. It has it's own LCD monitor for amps and volts that I should be able to remote inside the cabin area. Covers all 120v appliances, including microwave. Check.
2. Battery charger/converter (PD9270) is the largest potential "reverse user" which can be inferred to some degree by voltage. Inverter also measures this in the same display. Check.
3. Propane furnace fan is a big user. No way to monitor it right now. Need monitor.
4. Most lights are converted to LEDs. I will finish doing so soon. The draw of any/all is negligible. Check.
5. Electric side of DHW is unmonitored. Need lockout/relay/indicator.
6. A/C is unrestricted (electric heat strip also). Need lockout/relay.
7. Remaining battery level and time unknown. Need voltmeter as 'poor man's state of charge monitor'
Perhaps I don't *need* too much right now? If I were going to use just voltage to monitor batteries and remaining state of charge, what chart of voltages should I use? I've seen a number of them, but not very detailed.
Maybe my daughter and I can slowly play with an Arduino based monitor in the future as a project ;)
So if you only had VOLTAGE to work with, what would you use as your guide?
