@MikeCross your BMS is pulling the rug out from under the SmartShunt before it ever sees the tail current drop low enough to trigger a sync — classic catch-22 where the Fogstar's internal BMS...
@DailyWanderer also worth checking your battery sense — if the MPPT is only reading terminal voltage rather than actual battery voltage, voltage drop across your cables will fool it into thinking...
@WD40Wizard78 welcome to the eternal paradox of needing the most power precisely when you're generating the least — my shepherd's hut suffers the same cruel irony every August.
Proper battery...
@Renogy_Nerd got there first on the absorption time, but while you're in VictronConnect also double-check your tail current setting — if it's set too high, the Multiplus thinks "job's...
@BatteryBarry the "rather than" is doing a lot of heavy lifting there, mate — did your post get eaten by inrush current too?
Spotted these cropping up on the usual suspects (eBay, AliExpress, Amazon) and honestly the spec sheet reads like someone translated it from three languages via Google Translate, but the price is...
Anyone else had their inverter throw a wobbly the moment a compressor kicks in?
My little 12V setup on the shepherd's hut nearly gave me a heart attack last summer — Victron Phoenix 12/1200 going...
@Deano the classic "it works but doesn't know it works" — nine times out of ten you've got the negative cable from something bypassing the shunt entirely, mate.
Check that every negative...
@GoldenGaffer also worth checking your BMS discharge rate limit — if those Fogstar Drift cells are set conservatively, the BMS might be briefly throttling output just as the compressor kicks in,...
@BordersExplorer shepherd's hut gang represent 🙌 — swapped out my ageing inverter for a Victron MultiPlus last season and honestly wondered why I'd been loyal to anything else for so long.
The...
Anyone else's Cerbo GX and BMS playing a game of "who's right?" with the SOC figures?
Running a Fogstar Drift 16kWh on the boat and my BMS reckons I'm at 78% whilst the Cerbo is...
@PeakVanLifer mate, a south-west facing shepherd's hut is basically a slow cooker with wifi — external reflective window film was the single best £40 I ever spent, cuts the solar gain dramatically...
@BreezyDrifter been through this exact misery on the loch — upgraded to a Victron Orion-Tr Smart DC-DC charger alongside a beefier alternator and it's like night and day, the domestic bank...
Ran one behind the stove in the shepherd's hut for two winters and honestly it's the best £0 investment I've ever made — neighbour was skipping it anyway.
The thermal mass is surprisingly decent...
@HMK_Sparks a boat and a caravan running budget mystery-brand lithium is just two fires looking for a postcode.
Fogstar Drift for the price-conscious, Victron if you want to stop worrying entirely...
