Victron MPPT keeps dropping to float too early — anyone else had this?
Had this exact issue last summer with my 100/30. Kept hitting float by mid-morning even on decent days, which made no sense with the batteries only sitting at maybe 60-70% SOC. Turned out my...

Phoenix 12/375 blown fuse?
@NeilBurns91 the Phoenix 375 has a built-in fuse on the DC input side — think it's a 40A blade fuse tucked near the terminals.

Anyone else running a Renogy 40A DC-DC charger alongside solar on a split system? Curious about priority/charging conflicts
@Martin1962 yeah I ran a DCC40S for about 18 months before switching to Victron kit. The short answer is there's no real "conflict" — the DCC40S handles both inputs simultaneously and...

Anyone else had their BMS cut out in cold weather? What temps are you seeing?
Seen this exact thing with my setup last winter. The Drift's low-temp cutoff is around 5°C from memory — so 3°C overnight you were always going to trigger it. Worth adding a small self-heating mat...

Shed office solar setup — worth going bigger on the battery from the start?
JimKelly | 312 posts @BigAl31 went through exactly this two years ago with my 5x3 office. Skimped on battery initially and regretted it within the first November. Ended up with a Fogstar Drift...

Anyone else running Fogstar Drift lithium in a camper? Seeing weird BMS dropouts
Been running a 200Ah Fogstar Drift LiFePO4 under the bed in my Transit for about 8 months now. Generally happy with it but getting occasional BMS cutouts at around 20% SOC — Victron Cerbo is...

Anyone else noticed Fogstar prices creeping up lately?
Used to be the go-to for cheap LiFePO4 cells but had a look last week and the 280Ah Grade B cells are noticeably pricier than this time last year.

Anyone else running a split-charge relay alongside a DC-DC charger? Wondering if it's worth keeping both
@DriftKing had the same setup for a bit — kept the old split-charge relay "just in case" after fitting the Orion-Tr Smart. Honestly? Pulled it out after a month.

Anyone else finding their MPPT controller readings wildly off this winter compared to summer?
@HollyGraham83 yeah North Wales in winter is brutal for generation, not a fault thing. Low sun angle means your panels are rarely hitting anything close to rated output — 200W panels realistically...

Charging current in dvcc, and ESS
@FZ_Builds with flooded LA you probably don't even want DVCC's BMS_CCL capping your charge current too aggressively — those Rolls cells genuinely need a decent absorption phase to gas a bit and...
