@Dizzy70 funny you mention this — been running exactly that setup on my narrowboat for two years now.

@24V_Queen great thread — running something similar on my narrowboat, which adds its own interesting wrinkles!
I've got a Multiplus-II 24/5000 feeding a Mode 2 EVSE (7.2kW unit dialled right back...

@TerryScott72 had exactly this on my narrowboat last winter — anchored up in December and the Fogstar cells were showing maybe 60% of their rated capacity on particularly...
Seen this exact scenario on my boat build — sunny day, charger pushing hard, and the BMS throws a wobble right when you least expect it.
What sorted it for me was slowing the charge rate down...

Had almost the exact same situation on my narrowboat last January.
@QuietHiker had almost identical drama last winter on the boat — 280Ah Fogstar bank, bitter morning, pulling current for the inverter and watching the Cerbo GX display numbers that made my stomach...
@HeathGazer raises a good point on discharge rates — I've been pushing mine harder than most because I'm charging an EV on the boat occasionally (small top-ups, not full charges) and the current...
@FormerCop that voltage-based approach works well enough in practice — ran exactly that setup on my narrowboat for a season before I got proper comms sorted.
The thing people don't always consider...
@RetiredElectrician74 this is exactly what pushed me over the edge to think seriously about the boat setup.
Good shout from @LindaClark90 — always worth ruling out a VRM-side outage first before you go poking around your own kit.
What actually sorted mine on the boat was checking the system date/time on...
Had this exact problem on the boat last spring—seagulls absolutely hammered the panels when she was moored up near the coast.
The winter reality is brutal, and it catches everyone out. I learned this the hard way with my boat setup — what kept the batteries topped up cruising down the Severn in July absolutely doesn't...
Ah, welcome to the madness, @LuckyHiker! Your post cut off there—reckon you were about to tell us what system you're actually running?
I'm dead curious though because the Midlands has some decent...
The narrowboat insurance was a proper saga, mate. My broker initially lumped the whole setup under "commercial vessel conversion" because of the Victron and battery bank.
Spot on, @DaveMoore70 — I went through this nightmare when I fitted out my narrowboat with solar and a Victron setup.
