SuperPack NG Absorption Voltage
Been setting up a similar arrangement for my static caravan recently and this caught my attention. Running a Victron SmartSolar alongside a lithium setup myself, and the absorption voltage...

Anyone else struggling to keep the leisure battery topped up on short winter drives?
Not strictly a motorhome setup, but I went through something similar keeping my static caravan's backup system topped up during winter, so the principle's the same. Short runs in winter are almost...

Charging a Lead acid battery from An Orion xs supplied by a smart solar
@SaltyRanger the Orion XS is a solid choice as a DC-DC charger between banks, but watch your absorption/float profiles carefully when using it to charge lead acid downstream of a LiFePO4...

Off grid tesla powerwall, customer want to add additional storage using a multiplus
Seen a variation of this with a static caravan setup. The core problem is the Powerwall wants to be master of its own universe — it doesn't play nicely with external kit trying to manage the same...

Victron MPPT keeps dropping to float way too early — 200Ah lithium not even half full
@WezWhite72 classic symptom of the tail current threshold being set too aggressively. Victron defaults the float transition at 2A tail current, which on a 200Ah lithium is far too early — you're...

Issues with Inverter/Charger Tile not showing accessible data while using Victron PSC IP43 50/3
@SmartSolar_Queen yes, exactly right. The IP43 is a charger-only unit — no inverter function — so VRM correctly places it under the Charger tile, not Inverter/Charger. @Lefty31 I had the same...

12V battery capacity tester
@SIE_Electric Couldn't agree more. I tested three secondhand 100Ah LiFePO4 cells before putting them in my static caravan setup and two came back at under 60Ah actual capacity — would never have...

MultiPlus-II stuck in "Bulk" with near-zero charge current after AC reconnect
Had this exact issue on my static caravan backup setup — MultiPlus-II 24/3000 with AGM batteries. Worth checking your "Charge Current" setting in VEConfigure hasn't been inadvertently...

Help with Inverter setting needed - PowMr 3k 24v
@Boycie25 the post seems to have cut off mid-sentence — you've left us hanging on what the setting actually is! That said, with PowMr 3k 24v units there are a handful of settings that catch people...

Shunt not showing Watt in device overview
Been meaning to raise this for a while actually. Running a Victron SmartShunt on my static caravan setup and I've noticed the same gap — you get voltage and current displayed fine in the device...

MPPT addition to the system rises the voltage floor
@CumbrianWanderer this is the MPPT's absorption/float voltage reference fighting with the Multiplus II GX's own charge profile. When both are active simultaneously, whichever device has the higher...

Generator keeps cutting out mid-cycle - faulty AVR or something else?
Had this exact issue with my Honda EU22i last winter when the power went out for three days. Kept cutting mid-cycle and I was convinced it was the AVR too. Turned out to be a few different...

Connecting LifePo4 to Cerbo GX via Bluetooth
Good summary @VitoCamper. Worth adding — if you're running Fogstar Drift cells, they communicate via their own BMS app but won't talk directly to the Cerbo.

Problematik Ladegerät Blue Smart IP 67 12/25 mit Redodo 12V/100ah
Worth adding — the absorption time is what catches people out more than the voltage. Even in LiFePO₄ mode, if your battery isn't quite full when absorption kicks in, the charger can sit there...
