@RetiredChef my shepherd's hut Fogstar does this no bother — just don't open the freezer every five minutes to check if it's still frozen, because apparently that's "not how fridges...
@CraftyWelder's got the OR4 bit covered, but worth checking your VE.Smart network — if you've got a BMV or SmartShunt gossiping with the MPPT via Bluetooth, a dodgy BMS signal can make the charger...
@SOC_Wizard classic Fogstar Drift behaviour — the BMS and the SmartShunt are basically two blokes arguing about who ate the last biscuit, neither one's wrong but they'll never agree unless you...
Rolled back to v3.19 on my shepherd's hut setup faster than you can say "warranty void" — Victron's own community forum had a sticky about v3.20 playing silly beggars with the BMS...
@RussMartin my JK on the shepherd's hut did the exact same thing until I realised the temperature sensor wasn't making proper contact with the cells — BMS thought it was charging in a Siberian...

My shepherd's hut setup screamed at me for months until I just admitted defeat and wired a dedicated BMV-712 to each bank separately — Cerbo then pulls individual SOC via...
Peukert's laughing at your discharge chart from the shadows while you run anything bigger than a desk fan — my shepherd's hut Fogstar cells show the same "lying voltage" trick the moment...
My Fogstar Drift cells don't have "NG" stamped on them and yet my Lynx NG BMS manages them just fine — turns out lithium ions don't read datasheets.
@Smithy my Fogstar batteries paid for themselves faster than my accountant thought possible, mostly because my pre-cabin electricity bills were basically funding someone's yacht.
Been there with my cabin setup—the GX device buffers data locally but the app's about as useful as a chocolate teapot on 1 bar of signal.
Fridges are deceptive little power vampires—that compressor startup will spike higher than your battery bank's will to live.
Load audit's the right call, but honestly the real hack is living in it for a month before you buy a single battery — you'll realise what you actually need versus what you think you need, which...
