JakeShaw96 | 47 posts @NeilSmith yeah had almost the exact same thing happen last October with my 8s setup.

Running a small off-grid tiny house and trying to work out the best way to charge my 100Ah lithium (Fogstar Drift) from the van's alternator when I'm moving the structure.

Roger1983 | 1,247 posts Worth mentioning engine run time as part of your overall strategy too. On my boat I've got a 100A alternator with a split charge relay, and even a 45-minute cruise every...

HeatherGazer | 312 posts @SimonPalmer cold actually boosts panel efficiency — lower cell temp means higher Voc.

@HollyGraham83 North Yorkshire winters are brutal for solar — low sun angle kills output more than cloud cover does tbh. Few things that helped on my motorhome setup: Tilt your panels if you can...

Fitted a MultiPlus-II 24/3000/70 in my narrowboat about three months ago, running off a 200Ah lithium bank (two 100Ah Battle Born cells in parallel).

Running a 200Ah 12V LiFePO4 bank in the garden office using four Fogstar Drift 50Ah cells I picked up last year. Paired with a Victron SmartSolar 100/30 and a Multiplus 12/1200.

Running a 24V system in my van conversion — 280Ah of Fogstar Drift LiFePO4 cells wired in 2P configuration, paired with a Victron MultiPlus-II 24/3000 as the main inverter/charger.

@BrianKnight86 makes a solid point on voltage — worth running the numbers properly, not just guessing. On the mixing question itself: I've done similar with my setup and the main thing people...

Good points from everyone already. One thing worth adding — check your cable run between the panels and the controller.

@Jess1972: Ha, @Boycie25 I'm going to guess @OffGridJulie is about to say something unprintable 😄 Anyway, I've got a proper mixed bag of experiences with Facebook batteries.

@DucatoSolar also worth thinking about alternator charging from the engine — narrowboats run their engine way more than vans do, often daily for heat and water pumping.

@VitoProject one thing I'd add — check your DC input low voltage thresholds in VE.Configure. If they're set conservatively (easy to do with LiFePO4 cells), the Multiplus can start throttling...

Jim1985 | 847 posts @Tommo10 Yeah, had almost identical grief with a cheap shunt before I upgraded. The issue with those budget units is often the shunt resistor itself — the tolerance goes right...

Finally got the hut positioned on the south-facing slope of the field last autumn and have been slowly piecing together a system ever since.

@VanLiam classic problem — the Cerbo is brilliant until you plug in something it can't talk to, then it sulks like a teenager 😄 A few options depending on your inverter: If it has a RS232/RS485...

Last summer I rewired my Transit-based van and fitted a Victron Orion-Tr Smart 12/12-30A DC-DC charger to handle the alternator-to-leisure charging properly, especially since the van has a smart...
