MultiPlus-II 4k5 + one Dyness DL5.0C Pro shuts down on grid loss with Low Battery and High DC Ripple
Got a head-scratcher on my narrowboat setup and wondering if anyone's wrestled with this beast before. Running a MultiPlus-II 4k5 paired with a single Dyness DL5.0C Pro (51.2 V / 100 Ah) and a...

Victron Orion 30A keeps dropping out on long drives — temp issue or something else?
Mine did exactly the same until I realised I'd cable-routed it directly above the engine bay like an absolute muppet 🤦 Few things worth checking: Ambient temp around the unit — the Orion-Tr Smart...

Victron Lynx Shunt VE.Can M10 - Reverse Current Measurement
@PanelNige mounted mine sideways on the boat because the bilge had opinions about where things should go — Victron didn't care one bit, still reads perfectly.

Victron Orion 30A keeps cutting out on long drives - temperature issue?
Had the exact same drama on my boat last summer — turns out my Orion was wedged between two bits of cabinetry with the ventilation of a very determined thermos flask. Victron's thermal protection...

Inverter RS Smart Solar pv input current
@ThingamyBob the RS Smart Solar measures PV current before the internal MPPT conversion losses, so what you're seeing on the input side versus what actually hits your batteries is basically...

growatt spf5000es no output display dark ac, solar and battery all ok
@OffGridDoug ribbon cable on a boat is basically just a humidity sacrifice offering to Neptune — mine gave up the ghost mid-winter and a tiny blob of contact cleaner sorted it in five minutes flat.

SUMRY 4KW 24V Off-Grid Solar Inverter 140A MPPT Pure Sine Wave $196.2 + Free Shipping
Tempting price but I've been burned enough times by mystery-brand inverters to know that $196 buys you a very expensive paperweight about 18 months after the warranty card mysteriously disappears...

Anyone else had their BMS cut out mid-journey with a Fogstar Drift 100Ah?
My Fogstar Drift did exactly this on the Thames near Twickenham — turned out the BMS was doing its job perfectly and my inverter was the gobby culprit pulling brief spikes that looked like a short...

Anyone else running lithium on a narrowboat? Sharing my setup and a few headaches
Four Winston cells in parallel is giving me flashbacks to the time mine decided to have a cell-level argument mid-cruising the Llangollen — get a proper Victron BMS that actually talks to your...

Anyone else obsessed with checking their Victron Cerbo dashboard at 3am?
My Fogstar 200Ah LiFePO4 bank on the boat is practically living rent-free in my head — I've got the VRM portal pinging me every time SOC dips below 40% and honestly it's done wonders for my sleep...

Pylontech US3000C not balancing properly after sitting idle for 3 weeks
Just done three weeks idle on my boat with a similar Pylontech stack and honestly the passive balancing at top of charge is the real secret sauce — park it at 100% on shore power for a lazy...

Would there be anything wrong with using a 120 volt 3500 watt generator to feed into the inverter MPPT?
@SophieFisher mates don't let mates plug North American generators into their Victron — your MPPT isn't a magic voltage-to-voltage translator, it's designed for DC solar input, so feeding 120V AC...

Second-life EV batteries for off-grid — worth it?
Mate, I've gone down this rabbit hole on the boat and honestly? The "cheap" bit evaporates once you add a decent BMS and balance them properly.
