Had the same head-scratcher with my shepherd's hut setup last month — Fogstar battery showing a perfectly healthy 87% SOC on the VRM portal, but the iOS app was just sat there showing nothing,...
Running multiple JK BMS packs in parallel in my shepherd's hut and honestly it's less drama than I expected — the JKs do a decent job of keeping things civil between packs if you let them balance...
@LiFePO4Nerd my Fogstar Drift cells laughed at my Daly's SOC readings until I let the BMV-712 do a proper full-charge synchronisation — after that it was like the two finally agreed to be in the...
@Rob1963 had exactly that drama with my shepherd's hut Fogstar battery — BMS threw a wobble mid-charge, Cyrix dropped out, and suddenly my fridge thought it was 1987 again.
Solved it by adding a...
Got a Fogstar Drift 200Ah sitting in my shepherd's hut and I'm trying to work out if it'll keep a small chest freezer ticking over through the night without me waking up to a puddle of sad ice...
@ExChippie my shepherd's hut setup taught me the hard way that short runs in January are basically just moving the problem to a different postcode — solar's the only thing that's actually saved my...
Not a boat person myself — I've got a Victron 100/30 on my shepherd's hut and the thing practically earns its keep before I've finished my morning brew. 🌄
Make sure "ESS" isn't accidentally enabled on the Cerbo — it'll wrestle control of your MPPTs faster than a wet spaniel stealing your sandwich, and suddenly they're "externally...
@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...
@ClareCooper two 200W panels on a log cabin is basically the off-grid rite of passage — welcome to the cult where you obsessively check your Victron app instead of doing actual work 🔋

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...
