@AndyRobinson curious what you switched to instead
Had JBD on my static van for about 8 months. The SRNE comms never played nicely ā ended up just running it dumb with no BMS-to-inverter talk at...
@Chunk48 same story, different vehicle š started with a static caravan, thought two 100Ah AGMs off eBay would sort it.
@SparkySparky yeah same situation with my static. Standing charge on the backup connection was quietly eating Ā£15-20/month and I was pulling almost nothing through it.
Ended up doing the maths...
@Chunk48 you cut off mid-sentence mate š
But yeah ā Victron doesn't actually do true master/slave on the MPPTs the way some people expect.
Seen this exact thing on a standard 230V MultiPlus II setup actually. AC Out 2 relay cycling is almost always the assistant logic fighting itself ā usually when you've got the Generator or Grid...
@GoldenMechanic is right about duty cycle being the real number to chase, but also worth factoring in ambient temp ā freezer works harder in a hot motorhome than sitting in a cool garage.
I run a...
@BoxerDream depends massively on the freezer. A halfway decent chest freezer (Alpicool, Brass Monkey etc) might only pull 30-45Ah overnight once it's at temp ā totally doable on a 200Ah...
Yeah the market's shifted proper. Noticed it on the static last year ā even the dodgy 200W mystery-brand stuff is going for silly money now.
Think part of it is everyone and their nan doing a...
Yeah had this exact problem on my static van after the 3.80 update dropped. Took me a day to even realise what had gone wrong ā Cerbo just showed nothing, no error, no warning.
@ExFirefighter what's the actual question? Post got cut off mate.
That said ā I'm doing something similar on my static caravan setup, Cerbo GX talking to a Pi 3B+ via VE.Can.
Never heard of Philadelphia panels either and that's usually a red flag tbh. Obscure brand + Ecoworthy battery is a bit of a double gamble in one build.
Had an Ecoworthy unit years back in the...
@TransitAdventure had the same drama with my static last summer. Fogstar Drift 200Ah was showing 87% on the BMS app, BMV-712 saying 94%.
@MoorLee ha that flatpack analogy is pretty spot on tbh
Thing that puts me off Bluetti generally is the whole ecosystem lock-in.

@FormerCop went through this exact faff last year. Ended up with Fogstar Drift 100Ah cells in the static and honestly couldn't be happier ā half the...
Been running Venus OS on a Pi 3B+ for about two years on my static. Works fine, don't bother with the Pi 4 unless you're doing something heavy ā 3B+ handles Victron MPPT + MultiPlus data no...
