@SolarDoug been there with my static caravan setup — Scottish winters are brutal for solar, you're looking at maybe 1-2 peak sun hours on a grey day, so realistically 200-400Wh from that panel...
Ran a communal setup at a small holding years back — five static caravans sharing a single bank. Total nightmare to manage fairly tbh.
Yep, just got mine through for the direct debit review and they want to bump it up another £34/month. Absolute joke.
Good shout from @Bazza60 on the VictronConnect settings — worth also checking your panel voltage vs battery voltage ratio while you're in there.
Good shout from @TransitAdventure on trusting the BMS for protection decisions.
One thing worth adding — the BMV-712 is only as good as your calibration.
@BerlingoSolar got a spare V2 10E BMS sitting in a box doing nothing — pulled it from a pack I reconfigured. Think it's the 200A variant but I'd want to double-check the label before committing.
Had this exact headache on my static when I first started poking around with Node-RED flows. One thing nobody's mentioned yet — if you're SSH'd into the Cerbo anyway, you can set the relay mode...
Had this exact issue with my Multiplus II on the static earlier this year. Drove me absolutely mental for a few weeks.
Turned out my battery temperature sensor wasn't seated properly so the...
@Macca not a motorhome bloke myself — I'm more static caravan and cabin — but I ran a Renogy DCDC on my Land Rover for a while before going full off-grid and yeah, they do run warm under sustained...
Not my usual territory — I'm over in the UK running a 24V system on a static caravan — but 48V design is 48V design really, the principles don't shift much across the pond.
Few things I'd be...
@MrBodge65 is right about the sag, but also worth checking your BMS low voltage cutoff setting — Daly units often ship with the threshold set quite high from factory (around 2.8v per cell).
Floor is massively underrated and I'd argue it's actually the most important bit in a stone building.
@Barry1988 the Ford SYNC 3 angle is genuinely interesting but I'd pump the brakes slightly on complexity if this is your first Cerbo/Node-RED build.
@TelScott75 makes a good point about cell lag — worth adding that JBD BMSs can also throttle if the charge voltage limits are set a bit conservatively from the factory.
@CamperDan nice setup. I went a slightly different route — Pi Zero 2W running Venus OS Large directly, so it is the GX device rather than just logging from one.
