Not really

Still $1,000 for the group 27 equivalent.

That's a lot of Trojan T-105 golf cart batteries in trade for one Li Ion. $1050.00

I love my BATTERY MONITOR PANEL... i can monitor each battery bank for their 12VDC levels and a master DC current flow of whats connected to the battery bank.

I can tell at a glance what is happening long before it gets into a dark situation.

I also can run on one battery or all batteries by switching in and out each battery as required. This allows me to charge one battery by itself and run off the others at the same time...

Great PLAN B thing... One hiccup will not put me into the dark...

You sound like you used to be a cruising boater. I had a system like that. So sensitive it would respond to the volume of the stereo.

To the OP, get in the habit of turning the fridge, water heater & microwave circuit breakers off BEFORE turning the inverter on. Surprising how much a fridge takes on AC & how little on propane.

Keep saving and you will be getting Li-Ion by the time those give up in 5+ years ;)

Chris Bryant suggested to unplug the wires in the board going to the eyebrow and clean and that fixed the problem.

Took me a while to figure out who that was.

Yeah, they're going on 5 years and I want AGM's anyway!

Even though the batteries were too low to run the inverter, the DC-DC converter kept the house voltage at 12.5. That was a nice surprise.

But at least you will be warm with the lights on to figure out the issue.

Was boondocking yesterday and couldn't figure out why my batteries were draining. The inverter shut down last night from low voltage.

Turns out the Dometic refer switch to gas was not actually switching. Played with it a few times and it seems ok now. Heads up for anyone with similar "where's the juice going?" issues.

I don't know how common this problem is but when this happened to me it would not switch from gas to electric even though I was plugged in and on auto. Chris Bryant suggested to unplug the wires in the board going to the eyebrow and clean and that fixed the problem.
