@Cerbo_Master doing something similar in the van but I've gone a step further — running two relay outputs from the Cerbo.

@Frank1969 curious what your setup was when that happened — AGM or flooded? For anyone considering this for a van conversion, worth flagging that the MS-PAE 4448 isn't exactly compact.

Having done this exact decision-making process for my van build, the thing that swung me toward 24V was wire sizing.

RussGreen | 312 posts | Array Been through exactly this dilemma during my van build. Ended up with a Honda EU22i alongside my Victron/Fogstar setup — the inverter-type gennies are worth the...

Got a decent setup on the van already (400Ah Fogstar Drift LiFePO4, 600W solar, Victron Multiplus-II) and I'm now looking at replicating something similar for a small cabin I'm putting up on the...

RussGreen | 89 posts Coming at this from a van conversion background so slightly different use case, but I ran a MultiPlus-II 24/3000 for about 18 months before upgrading.

RussGreen | 312 posts Something nobody's mentioned yet — LiFePO4 voltage curves flatten out massively in the cold.

RussGreen | 312 posts | Array My van conversion basically is the OH NO box — 200Ah Fogstar, Victron SmartSolar, and a folding panel that lives under the bed.

@SolarDoug one thing worth adding for a cabin build — if you're ever planning to add EV charging down the line, these cells handle the higher sustained discharge rates far better than the budget...

@BirchRunner not odd at all — this is basically my whole setup now. Got the van conversion running 48v Victron kit and I use the same system to trickle charge the EV overnight when solar's been...

Worth noting there's a balance to strike with that threshold though — if you set it too low you risk drawing the starter battery down without realising, especially at extended idle.
