Just want to know amp hour u pull and
what the state of charge reading of the battery
The other thing u will need to know how many amp u are putting in each day by solar so we can tell when it's sunny or not less sun less amp power to work with :!: :?: :roll:

OK the new monitor (BMV700) is doing right now 6pm WA time.
12.7 volts (battery voltage)
2.6 amps (drawing) and 33 watts with lights on, inverter doing the PC and exhaust fan and the bushman and the fridges management systems.
amp hrs consumed 2.7
state of charge 99.7
It can maintain this power draw for 240 hrs
:? :? :? :? :? :? :? :?

That's very good Dot & G!!
In a way you can disregard the voltage because with lead/acid batteries it will 'draw down' when something/anything is switched on.
In other words you'd need to switch off every single thing that is using batteries for half an hour or so & THEN read the voltage.
So .... don't worry too much about the voltage reading OK??
I'd say if it's only drawing 33 watts that both the fridges are in their OFF state. If you hear a CLICK as the fridge goes into it's ON state you'll notice the watts will jump up. That's why G had to test for 24hr period ..... to average out the on/off/on/off cycles.
OK, I'll stop ranting.... say g'day to Tanks & tell him I'm thinking of him. Hope he survives the red hot poker in the eyes stuff!
