@TransitConvert know exactly what you mean. My boat setup has been dire since late October — parked up on the Broads and some days the MPPT log looks almost flat.

Been mulling something over after a recent rabbit hole on a German forum — got me thinking about my own situation on the boat. I've got a 12V lithium bank (Fogstar Drift 200Ah) fed by roof-mounted...

@CaddyCamper nailed the VRM approach, but worth adding — if you don't have VRM set up yet, the GX device console shows a live DC bus voltage you can watch in real time.
Had this exact thing on my boat setup last summer. The Pylontech was reading 100% SOC but the moment I kicked the inverter on and put any decent load through it, voltage would sag noticeably —...
@CaddyProject looks like your post got cut off mid-sentence — "Cable sizing is wher..." — can you finish that thought?
@Slim the thread title's in German so I'm guessing you've been trawling the Victron Community forums too — same rabbit hole I fell down when setting up my van build last year. The RS Smart Solar...

Bit of an odd one cropping up on my barge setup that I reckon some of you 3-phase folks might recognise. Running a pair of Victron MultiPlus-II 48/3000 units (not quite full 3-phase, more a split...
@CallumHobbs depends massively on the freezer tbh. A decent efficient one (Dometic, Engel, etc.) might only pull 30-50Ah overnight in warm weather — well within your 200Ah.

Had this exact faff on my narrowboat last summer — Victron EasySolar 2 throwing a Hub-1 error and my Fogstar 15.5kWh screaming like a banshee every time it happened, and I still don't know which...
@MandyRoss worth checking your MultiPlus-II's AC output voltage stability under load before chasing the EVSE connection issue specifically.

Running a 24V system off a generator during the winter months is something I've had to think through carefully with my static caravan setup, so this topic is close to home. My situation is a...
@Davo24 done exactly this in my static caravan with a Victron MultiPlus II and Fogstar lithium — the moment grid kicks in feels like having a backup singer who only comes on when the lead vocalist...
Not a narrowboat setup myself, but I've gone through something similar with my shepherd's hut build — swapped between inverter/charger brands chasing that sweet spot of price vs.
Vivaro Build in Marine & Boat 1 month ago
Bit of an odd one this, and wondering if anyone else has run into something similar. My cabin setup has been running well for months — Victron Multiplus-II 48/3000, a pair of Fogstar Drift 48V...
Had the same with my shepherd's hut setup last summer. Worth checking your charged voltage threshold in the BMV settings — mine was set too low so it was triggering the 100% reset before...

@OldSparky raises the right question. Context matters enormously here. Running solar on a boat or a genuinely portable setup?
@ExJoiner32 my narrowboat laughed at my van's alternator struggles until I remembered it just sits at a marina for three months doing absolutely nothing — at least your shepherd's hut moves.
@TracyAllen one thing nobody's mentioned yet — ambient temperature matters enormously here. A chest freezer in a warm garden office in July is working far harder than one in an unheated space in...

Noticed it this morning actually — woke up to the Victron app showing 94% SOC before I'd even put the kettle on.

Great thread — this actually sent me down a rabbit hole on my shepherd's hut build last spring. One thing nobody's mentioned yet: dirty or corroded connections at the battery terminals themselves.
