@DaiYoung56 good point about the SmartShunt generally being more reliable, but worth adding — it's only as good as its calibration.
Worth adding to what @SaltyMaker said — you can actually disable adaptive absorption in VictronConnect if you want fixed-duration absorption every time.
Interesting price point, though I'd be a bit wary jumping on an ECO-WORTHY LiFePO4 without knowing more about the BMS internals.
Something that hasn't been mentioned yet — check your absorption time settings in VEConfigure. In ESS mode the MultiPlus can be told to use a fixed absorption time, and if it's set too short (even...
Had this exact situation in the van last winter parked up in the Fens — brutal cold snap, woke up to nothing.
One thing nobody's mentioned yet: your heating being the thing that needs power is...
Been going back and forth on this for a few weeks now. Converting a Sprinter and trying to keep costs down — proper Fogstar or CALB cells would obviously be ideal but I'm looking at £400-600 just...
@MidlandsBoater worth checking whether your Victron PWM has temperature compensation enabled — the BlueSolar PWM-Light does support a temp sensor accessory but it's not always wired in out of the...
Another option worth considering if the Cerbo feels like overkill — the Victron SmartShunt paired with a cheap Android tablet running VictronConnect locally.
Fair bit of crossover between van and boat electrics so hopefully useful — I run 280Ah of LiFePO4 in my van and condensation is absolutely a killer if your battery compartment isn't ventilated...
Running a Victron Orion-Tr Smart 12/12-30A in my Transit MK7 (2009, about 180k miles). Been working brilliantly for about 8 months, then last week the unit just stopped charging mid-drive.

Had almost identical symptoms in my Transit last January — turned out the Victron was hitting the absorption voltage earlier than expected because the panels were...
@RogerJackson I run a Cerbo GX in my van and the scheduled charging/sleep schedules via VRM are worth looking at — you can set the Cerbo to reduce polling intervals which shaves a bit off the idle...
Insulation really is the first move though. I've got 50mm rockwool in my van roof and proper window shutters—made a ridiculous difference to how hard the heating has to work.
