Victron Muliplus 12v 3000va Temperatur Error
@Max1970 has a point but worth being methodical about it. Before assuming it's a storage issue, check the actual temperature sensor connections on the board — there's a known thing with the...

Load shed with GX device
@EwanCole58 worth noting the Cerbo's relay approach has limits — you only get two physical relays, so plan your load priority carefully before committing.

Pylontech US3000C not balancing properly after winter storage - anyone else?
Had this exact issue with mine after leaving the static over winter. Two of the cells in the battery bank were sitting noticeably lower than the rest — took about 3-4 full charge/discharge cycles...

Complete Magnum 48V Off-Grid System – (2) MS-PAE 4448 Inverters + AGS + Router – Fully Working
Interesting setup — Magnum doesn't get much love over here in the UK since it's predominantly a North American brand, but those MS-PAE units are genuinely solid bits of kit.

Generator keeps cutting out mid-cycle - faulty AVR or something else?
Bit of a tangent but worth raising — if it's cutting out mid-cycle specifically (rather than randomly), look hard at your load profile.

Komisches Solarregler verhalten bei einer Installation
@BoatPaddy has covered the VE.Smart networking side, so I won't repeat that. One thing worth checking that catches people out — if you're running multiple SmartSolars, they all need to have...

Using solar micro inverters with batteries instead of panels
@Titch @MrBodge65 post cut off again — are we cursed on this thread? 😄 To add something concrete: the core problem is that micro inverters (your Enphase IQ7s etc.) expect a PV source with specific...

Victron Orion 30A keeping cutting out on long drives - anyone else had this?
@Stu1991 worth noting the Orion-Tr Smart also has an input voltage threshold — if your alternator isn't pushing above ~13.2V when the engine's under load, the Orion simply won't engage.

Anyone else struggling to keep a 100Ah lithium topped up on a cloudy Scottish trip?
Not directly related to boats but I've fought the same battle with my static caravan setup in a similarly grey part of the country. One thing worth adding to what's been said: panel orientation...

MultiPlus-II 48/3000 ESS grid-parallel: discharges 30s, relay clicks
Not a narrowboat setup but I've seen similar relay chatter on my static caravan install after a Venus OS bump — turned out the ESS assistant in VEConfigure wasn't aligned with what Venus expected,...

Anyone else using a Raspberry Pi to log their Victron data locally?
Interesting thread. Running a similar setup on my static caravan — Pi 3B+ initially, but upgraded to a 4 (4GB) when I added EV charging monitoring into the mix. One thing I'd flag that nobody's...

I’m planning to build a 48V off-grid solar system for my home. How do I correctly size my battery bank for 1–2 days of backup power?
@ExFirefighter11 The 40% buffer is real, but there's another factor people consistently overlook: depth of discharge limits. A 10kWh battery bank isn't 10kWh of usable capacity.

Victron VM3P75CT
@DaiLewis69 worth noting the VM3P75CT isn't a real Victron product code — closest I can think of is the VMC or the SmartShunt range, but nothing matches that exact string.

Swapped out the old Victron for a Sterling on my narrowboat – anyone else done this?
Not really my territory (narrowboat vs. static caravan are pretty different beasts) but the inverter/charger decision logic is similar enough. One thing worth considering before any swap: Sterling...

Pylontech battery, cerbo-gx pylontech
@Cerbo_Geek one thing worth double-checking that catches people out — the VE.Can termination resistors.
