Had this exact issue last winter with my 100/20. Drove me mad for weeks thinking it was faulty.
Turns out it's pretty normal behaviour — when irradiance drops really low the MPPT can't maintain a...
Been thinking about this one for a while and curious if others have run into it.
Running a couple of Victron Orion XS 50A units in my setup — one dedicated to shore power input, another for a...
Been running an EasySolar-II GX 3kVA here with a Fogstar Drift 200Ah lithium setup and had a similar situation crop up recently.
Picked up a cheap single-ring induction hob (not the IKEA one but...
Both have their blind spots tbh. BMV-712 drifts if your shunt isn't wired correctly — every single DC load must go through it, no exceptions.
@ValleyChild similar setup in my van but same battery — the Drift has been solid through the cold snaps we've had.

@PanelHarry one angle worth thinking about — if EV charging is on your radar down the line, 48v gives you a much better foundation.
@ClareCooper nice one, finally cutting the extension lead cord 😄
What inverter/charge controller did you go with? That'll make or break the experience more than the panels tbh.
Had this exact issue with my setup. The induction hob surge on startup is brutal — mine was pulling nearly 2500W instantaneously before settling.
Few things to check that haven't been...
@Jim1980 had this exact thing on my camper van build. Check your cell internal resistance readings in the JK app — if one cell is spiking noticeably higher than the others under load, it'll drag...
Worth adding — the transfer time is super fast (about 20ms) so most sensitive electronics won't even notice the switchover.
@PikeSeeker what's your cable run length from the battery to the Multiplus? A kettle will pull close to 13A at 12V (roughly 2800W burst) and even slightly undersized or long DC cables will cause a...
Good shout from @DeclanKnight57 on corrosion — canal environment is genuinely harsh.
One thing I'd add from my solar experience: roof shading is a completely different beast on a narrowboat.
@JA_Solar worth looking into a small self-regulating heating pad wrapped around the battery — I run one on a thermostat in my van setup, kicks in around 5°C and draws barely anything overnight.
