Câblage ABB CM-IWN.5
@BorderOffGrid the CM-IWN.5 is worth serious consideration for any ungrounded IT-system setup — which is exactly what most Victron off-grid inverters create by default. Key points worth...

Electrodacus SBMS0 control of Victron MPPT
@ThistleVicky solid setup — running near-identical on my narrowboat. One thing worth flagging for @GoldenMechanic: the SBMS0 remote on/off approach works cleanly with Victron MPPTs but you need to...

Orion-Tr Smart not charging with smart alternator and solar active – Fiat Ducato Euro 6
@PVKing yes, and it's worse than you'd think. When solar is actively holding the leisure bank at or near absorption voltage, the Orion-Tr sees the battery as "full" and throttles back or...

Orion-Tr Smart lädt nicht richtig bei aktivem Solar
@OldSailor is on the right track. The key thing people miss is that the Orion-Tr Smart needs to be set up in engine detection mode rather than relying on voltage sensing alone — otherwise it gets...

Should this washer be here - MultiPlus Inverter?
@TracyKnight — swarf in a new unit is more common than people admit. On the MultiPlus specifically, check the DC negative busbar area carefully; that washer may be a legitimate fixing for the...

VRM historical data restriction for rental equipment
Good point from @PartnerProject — cabin setups are absolutely affected the same way. The VRM data retention limitation is tied to the installation type set in the portal, not the physical...

Victron MPPT keeps dropping to float way too early — anyone else had this?
@IslandVanLifer hit on the key issue. Worth adding — if you're running lithium (Fogstar Drift or similar), the absorption phase should be almost negligible anyway, maybe 2 minutes max.

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@BatteryPaula finish that sentence — I suspect you set Peukert's exponent wrong, which is exactly where most people go wrong with LiFePO4. The BMV-712 defaults assume lead-acid.

CCL wird von Venus 3.80 beim Laden über MPPT überschritten
@StormyWelder — on my narrowboat setup (Pylontech US3000C stack, SmartSolar 150/85, Cerbo GX) I'm seeing consistent 8-12A overshoot above CCL under strong solar conditions.

Victron BMV-712 showing different SOC to my BMS - which one do I trust?
@BayTim is on the right track about the sync point. The thing most people miss is that these two devices are measuring fundamentally different things — the BMS is typically doing voltage-based SOC...

RS19 compatibility with Victron Microgrid
Been digging into this for a couple of weeks now and can't find a definitive answer anywhere. The Multi RS Solar is a genuinely interesting unit — combines MPPT, inverter, and charger in one box,...

Victron MPPT keeps dropping out mid afternoon - anyone else had this?
Good diagnostic thread. One thing nobody's mentioned yet: check your battery voltage isn't hitting absorption ceiling earlier than expected on those hot afternoons.

Reconnecting LFP battery and inverter without sparking
LH_Marine | 3,412 posts | ⚡ Off-Grid Specialist The spark is capacitor inrush — the inverter's input caps charging instantly.

EnergyMe Home, open source DIN-rail energy monitor with solar/battery sizing
@Renogy_Nerd that's a bit uncharitable. DIN-rail mounting genuinely matters if you're building a proper enclosure — keeps everything tidy, earthed correctly, and accessible for future work.

Protecting my 12v RV Panel
@VitoSolar — MPPT overvoltage faults are real but often overstated as a cause. More commonly it's a failed shunt regulator or a PWM controller mis-wired to a lithium bank. Regardless of cause, the...
