Finally got my Cerbo GX wired up properly last weekend after it sitting in a box for two months. Running it alongside a Renogy 40A MPPT and a Fogstar Drift 200Ah lithium, neither of which talk to...

Interesting thread — I've got a JK BMS on my garden office build and noticed something similar last winter.

Hey @OwenYoung83, classic inrush current issue this one. Induction hobs are notorious for pulling 3-4x their rated wattage for a split second on startup, so your 2000W hob could be demanding...

Not a shepherd's hut but running a 200Ah Drift on my narrowboat — curious whether the low temperature cutoff has been an issue for any of you?

Really resonates with me this thread — spent two winters troubleshooting near-identical issues in my static caravan up in the Cairngorms before I cracked it. The thing that finally made the...

ShaunButler | 156 posts | Regular Member Great thread @SteveBurns. One thing I'd add that saved me a fair bit - don't overlook second-hand leisure batteries from motorhome breakers.

Right, so I'm finally pulling the trigger on the inverter/charger for my Fiat Ducato motorhome conversion and I've been going back and forth on this for weeks.
Hey @StuThompson, classic one this! Worth checking your cell voltage differentials when you're approaching that low SOC — the JK can be quite aggressive if one cell is sagging ahead of the others...

Good shout from @Megan1960 on the tail current — that's often the culprit that gets overlooked. One thing I'd add: with LiFePO4 the voltage curve is so flat through the middle range that the...

ShortCircuit56 | 847 posts Good point from @24V_Queen on the numbers. One thing nobody's mentioned yet — if your van is sat unused overnight, the battery itself will be cold when you start drawing...

Great thread! @Chippy33 that's a cracking result for under £200. One thing I'd add from my own experience — don't overlook your cable sizing.

CliffSpirit | 634 posts | ⚡ Solar + LiFePO4 + Wind + Genny backup @QG_Marine great thread — proper real-world testing is worth more than a hundred garden trials.

@OffGridDoug this caught me out badly my first winter at the cabin. What nobody mentions until you've lived it is how dramatically the panel voltage spikes in cold weather — physics of it means...

Totally agree with @Lefty72 on the morning brew ritual! I'd add that VRM really comes into its own for spotting gradual trends rather than just faults.

Been thinking about this a lot lately. I've got a 400W solar setup on my shed/workshop with a 100Ah lithium battery (Fogstar Drift), and it does the job most of the year.

@PanelRob ran something similar on my static — older alternator feeding a Fogstar bank via the Orion-Tr Smart.

Been running a 400W rooftop array (2x 200W Renogy mono panels) on my van since spring and it's been brilliant.

@ShortCircuit56 brutal lesson I learned last winter on the narrowboat — a 100Ah lithium sounds generous until a grey November day in the Midlands gives you maybe 15-20% of your panel's rated...
