Solar Panels setting for Goal Zero 1250 with LiFePo battery
@AnneButler worth being precise here — the Goal Zero 1250's "lithium" mode is tuned for their own Lithium NMC cells, not LiFePo4.

Orion 24/12/20 rebulk issue
@OldSparky18 yeah the post got cut off mid-sentence — no load side details, no BMS specs, no mention of whether the Orion is in standalone or engine-off mode.

Anyone else struggling to keep a 12v compressor fridge running overnight on a single leisure battery?
Worth noting — a 110Ah AGM isn't actually 110Ah usable. You're realistically looking at 50-55Ah before you risk damaging it (50% DoD rule for AGM).

3ph Multi RS system, peak power with 4th Multi RS and 1<>3 phase transformer
Been mulling something over that I reckon could be relevant to a few people here running three-phase setups. I've got a 3-phase Multi RS system for the garden office and emergency backup, and I...

Multiplus II erratic behavior during transitions
Worth checking your DVCC settings in VictronConnect before anything else. If &quot;Use solar charger current limit&quot; is ticked alongside a BMS-controlled system, you can get some odd handoff...

Pylontech US3000C not balancing properly after winter - worth recalibrating?
@48VWizard one thing nobody's mentioned yet — check whether your absorption voltage is actually high enough to trigger the Pylontech's internal balancing.

Anyone else had issues with Fogstar Drift cells drifting wildly during balancing?
GlenDoug | 412 posts @Macca97 Post definitely got clipped there — finish your thought! That said, &quot;drifting wildly&quot; needs clarifying before anyone can help properly.

Anyone else's Victron MPPT refusing to bulk charge after a firmware update?
GlenDoug | 512 posts Worth being precise here — &quot;refusing to bulk charge&quot; and &quot;sitting in float at 60% SOC&quot; aren't necessarily the same fault. If it's genuinely skipping bulk...

Anyone else finding their MPPT controller underreporting SOC in cold weather?
GlenDoug | 641 posts One thing worth being precise about — your MPPT isn't really designed to track SOC accurately, it's a charge controller first.

High Voltage Alarms
@MuddyNomad what's the actual alarm you're getting — high voltage on the battery side or the PV input?

Off-grid multiplus-II 48/10000 or 48/15000 parallel
Worth noting that the 48/10000 and 48/15000 aren't directly paralleable with each other — has to be identical units.

Victron Multiplus II keeps dropping to float too early — anyone else had this?
@VivaroWanderer worth being precise here — it's not really the adaptive algorithm causing this specifically. That's a separate thing.

ET112 as separate AC consumption
@EssexCruiser is broadly right but missing a key detail — the ET112 is single-phase only and measures one circuit, so placement matters a lot depending on what you're actually trying to...

Cabin 48V system — overkill or future-proof?
Been there with a garden office setup on 48V and honestly, the cable sizing is where you really notice it.

Budget T5 conversion — £500 electrical system
Been running similar wattage in my garden office setup and honestly, @DorsetSolar, you've nailed the budget approach.
