The batteries are parallel, so if one cell dropped and a BMS opened the other would still be online you would think. He’s reporting that the DC and AC drops so I would *think* it’s more of a current...

I completely agree that monitoring the shunt current during the run up to shutdown is a great plan, as is monitoring the fridge or unplugging it. Feeling cables for heat could be interesting too,...

Because the dc side is shutting down too I would guess bms too.

Low voltage cutoff could do it and it could be undersized wiring, imbalanced wiring or poor connections that are heating up and...

Victron 100v/30a times 2 (~$220 each) for charge controllers and redundancy.., They’re pretty great. They make 60a units too.

Familiarize yourself with the battery monitor that I would assume is on the bus first.

Lithium batteries can last a really long time if treated right and your usage may be different than the prior...

Yes, or get a solar charger that you can leave attached if the bus is stationary.

The consensus seems to be to air chisel the solid rivets as it saves boatloads of time. I took the Angle grinder to the sheet metal below the window, also a time saver.

It’s really hard to make any conclusion about battery state or what’s high or low without understanding the load on the battery and the loss across the wiring.

You can probably wedge 1.5” between the ribs on the ceiling if you take the ceiling down, which I definitely would do, then maybe .5” over all of that so you have a barrier between the ribs and your...

I would guess that nothing bad happened if you didn’t charge it all the way. You really need to keep the voltage lower than 14.6 to keep it safe but there’s a good chance if you have a built in bms...

I’d have to do the math a bit but I think this calculus may be changing. I can get 250w panels for $50-75 used as much as I want where I am. The hydronic panels are expensive and heavy, although I...

If you look at electrodacus bms and the diversion feature of the charge controllers it’s really interesting. Essentially you can automatically only use excess solar with charging as the priority. ...

I did some photography work for them when they were on Long Island. Awesome people, amazing product, but I would be surprised if they were under $10k, more like $20k+ I would guess.

At least on my bus I would say ‘doesn’t matter’ and move on! Best guess I have would be to run a coolant circulator or fan for a specified time after shutdown but it’s an absolute guess.

Dc kills ac contacts if they’re not rated for dc.

Your ac thermostat is not likely rated for dc and will likely die if you run the dc through it.

If you run ac through the thermostat and use...

I’m no expert in this but it seems like a good idea to me. A single 100 gallon tank is 800 lbs so 50s are way more manageable. Sloshing forces are real. Let’s just say a guy I know might’ve...

Look at your inverter and find the model number. If it’s an “inverter/charger” then it’s usually gonna charge your batteries when it’s plugged in and you may or may not have a choice about that.
