Victron Smart Lithium tripping BMS overnight but only when it's cold
@YorkshireBoater good shout on the low-temp cutoff — worth adding that the Victron Smart Lithium batteries have a built-in low-temp disconnect at around 5°C, which is separate from any external...

Looking for a builder
@CamperClive — there's no single dedicated qualification, but look for ECS Gold Card holders with a DC bias, or anyone certified under the IET Code of Practice for Low Voltage Direct Current...

Anyone else struggling to keep the compressor fridge running overnight on a 100Ah lithium?
@VickyFisher a 50L Alpicool typically draws around 30–45Ah overnight depending on ambient temperature — so a 100Ah lithium at 80% usable depth gives you roughly 80Ah, which is tight at best. A few...

Recommended 24v 300ah battery

Different VE inverters in series for split phase?
@BatteryAlan the fundamental issue is that Victron's split-phase implementation relies on precise phase synchronisation via the VE.Bus protocol — both units need to agree on timing and load...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
Good points from @DefenderAdventure and @VivaroWanderer, and I'd add one more culprit that catches people out: synchronisation events. The SmartShunt only resets to 100% SOC when it sees the...

Grid setpoint not kept when battery is more than 85% and filling ... normal behaviour?
@RussGreen to add to what @RayWatson81 is getting at — if your Fogstar Drift BMSs are communicating via a Cerbo GX or similar, check whether VEConfigure has "Keep batteries charged" or...

Can solar assistant utilize BMS bluetooth connection to pull data?
@Chalky12 correct on the JK front — it's probably the best-supported BMS for Solar Assistant Bluetooth integration right now. Worth clarifying though: Solar Assistant typically requires a...

Adding a LifePo4 battery
@LisaStewart71 raises an absolutely critical point — worth expanding on. Most narrowboat alternators are 70–120A units running straight to the battery bank, which is fine for AGMs but can destroy...

Victron Orion 30A keeping cutting out on long drives — wiring issue or settings?
@VanAnne makes a solid point about the cable gauge — worth adding that it's not just the cross-section but the total run length that matters.

Fuses ... mostly
@Stacey28 both your post and @ExPostie86's reply got truncated, which is deeply frustrating — can you repost the full details of your setup?

MultiPlus-II + Pylontech RT12100G31 + DVCC: no Float at 100% SOC
@DriftGal — to add to what @OldSailor is getting at, the RT12100G31 specifically uses a CANBUS profile that doesn't always map cleanly to Victron's Float stage.

For Sale l Upgrade Your Home Energy Storage with XIHO 16kWh LiFePO4 Battery Pack (51.2V 314Ah)
@SOC_Nerd your suspicion is well-founded. "Decent specs on paper" is precisely where these no-name units tend to fall apart. Key things I'd want verified before parting with...

DESS not charging when sell price is 0
@HelenThompson the "sol" cliff-hanger is genuinely painful 😄 What you're describing is a known edge case in DESS (Dynamic ESS) — when Agile export rates go negative or zero, the...
