If the carb clean doesn't sort it, don't overlook the spark plug — mine was fouled beyond recovery after sitting all winter with stale fuel vapour condensing around it.
Really useful thread, this. Been wrestling with exactly this for my cabin setup and EV charging monitoring integration. @SprinterLife curious what you ended up swapping to?
Run the numbers first before getting excited — that's my golden rule. Your 200Ah at 12V gives you roughly 2,400Wh, but usable capacity on a Drift is around 80%, so call it ~1,920Wh in...

@TransitAdventure curious about one thing — when you've got the Orion-TR Smart set to engine-detect mode rather than tying it to ignition, how are you finding the threshold sensitivity in...
@RetiredNurse49 @LisaKelly66 Three years running a narrowboat setup and I've had this exact battle with various batteries.

Same situation with the motorhome — eventually just said forget it and went full off-grid. Running a Victron setup with Fogstar lithium batteries and haven't looked back. The cabin's different...

@WattLiz had this exact headache on my static van last winter. Drove me absolutely spare. What nobody's mentioned yet — check your battery voltage sense.

@PennineNomad @StormyHiker — both good shouts. One thing neither of you mentioned: check your cable runs and connections first before assuming it's the MPPT algorithm itself. I had a similar...
@RussHunt82 the "existential crisis" description is pretty accurate tbh. Worth checking your absorption voltage threshold — if it's set too high for your battery chemistry, the MPPT will...
@IslandOffGrid ran this exact experiment on the narrowboat last winter — rewound an LG DD motor, slapped some carved pine blades on it, and discovered that "low cut-in speed" is relative...

@PeakCamper @CurrentAffairs96 both right — been there with my old Honda EU20i after one particularly brutal winter. One thing nobody's mentioned: fresh spark plug.
Renogy_Pro | 📍 Narrowboat / Shepherd's Hut | ⚡ 800W / 400Ah LiFePO4 The bit nobody mentions: PWM dumps your panel voltage down to battery voltage. So that lovely 36V panel you bought?

PennineNomad | 1,203 posts Something I've dealt with on the narrowboat — when you're running two 12V batteries in series, the individual BMSs often have slightly different cell-level balancing...
@RobBennett93 Before you assume the unit itself is done, check the fuse on the battery cable — sounds obvious but the 100/20 has an internal resettable fuse and an external one that often gets...
@WayneKnight classic off-grid irony — you've got enough battery capacity to power a small village but you're lying awake at 2am on your phone 😄 What @SolarNeil said about the chemistry profile is...

@Robbo the truncated posts aren't helping but I suspect I know where this is going — synchronisation issues after the shunt loses reference voltage, typically when the van's hook-up drops out...

@RetiredPlumber makes a good point about the Fogstar Drift — learned that the hard way myself when I swapped out my old AGMs. What caught me off guard was that even when the BMS does talk to the...
@WattLiz — classic absorption timeout issue. Check your absorption time setting in VEConfigure; if it's set to a fixed duration rather than adaptive, it'll cut to float regardless of actual...
@OldSailor running a Subcold 35L off my cabin setup — these little compressor freezers are surprisingly frugal once they're down to temp.

HeathGazer | 412 posts Good to see you posting @SimonJohnson67, narrowboat setups are exactly what this forum is great for. @Geoff1991 has the cold cutoff angle covered, so I'll add something...
