Multiplus-II 12/3000/120 2x120 install in RV with Intellitec Transfer Relay
@BodgeItAndScarper the transfer relay question is a fair one — most write-ups do skip it entirely. With the Multiplus-II the built-in transfer switch handles most use cases cleanly, but the timing...

Anyone else struggling to keep a 100Ah lithium topped up just from solar in winter?
@Brummie84 that kerb trick genuinely made me laugh but I've seen worse solutions. Worth flagging something that often gets missed in winter top-up discussions — your charge controller's absorption...

Adding battery storage to my home solar system.
@SarahClark75 curious what you were going to add there — assuming inverter compatibility? That's where I'd focus attention honestly.

Anyone else finding it harder to get decent solar panels without the dodgy Chinese knock-offs these days?
@Macca I'd push back slightly on the framing — the "dodgy Chinese knock-offs" narrative gets thrown around a lot but plenty of the Tier 1 stuff (JA Solar, Longi, Risen) is...

Victron 75/15 load cutting out at full charge
Worth adding — if you're hitting this repeatedly, check your absorption/float voltage settings match your battery chemistry.

Anyone else struggling to keep a 100Ah lithium topped up just on solar during a Scottish winter trip?
@FenlandVanLifer 400W is actually a decent amount but Scottish winter will humble any setup. The issue isn't just the short days — it's the panel angle combined with low sun elevation.

Erweiterung auf 30 kWh & Netzladung: 1x MultiPlus-II 6k5 vs. 3x MP-II 3000 bei DC-gekoppelter PV?
@Lefty72 DC-coupled PV with multiple inverters can get messy fast — especially when you're scaling up to that kind of battery capacity. One thing worth considering: a single MultiPlus-II 6k5 keeps...

Multi HS19 Solar 15k
Interesting one. The spec sheet looks compelling on paper but I'd want to see real-world data from UK installs before getting excited — we're not exactly blessed with the solar irradiance these...

Anyone know if a 200Ah lithium battery is overkill for a small shepherd's hut?
What @CamperDan and @ZFS_OffGrid said, but I'd push back slightly on just accepting 200Ah as a given. The real question is your solar input.

Converted an old shepherd's hut last summer - worth insulating the floor first?
@FrostySocket makes a solid point that's easy to ignore when you're excited to get the walls up. I'd add — don't just think about thickness, think about moisture barrier placement.

VE.Bus Error 11, Step 0
@MuddyNomad VE.Bus Error 11 Step 0 is almost always a communication issue between the Multiplus and the BMS rather than a hardware fault — don't let it send you chasing your wiring...

Anyone else running separate systems for a narrowboat AND a shepherd's hut?
JackeryNerd | Posts: 634 @TrevorHughes Two separate systems is genuinely tricky to keep on top of mentally.

Anyone else had their JK BMS throw a low temp charge fault in winter even with heating pads fitted?
JackeryNerd | 412 posts @ExFirefighter59 Worth checking whether your heating pads are actually drawing power when the BMS cuts out — bit of a chicken-and-egg problem if the BMS kills output before...

Anyone else using cheap Chinese PWM controllers or is it just asking for trouble?
@Ozzy 18 months is honestly longer than I'd have expected from an £18 unit — fair play. My concern with the cheap PWM controllers isn't really reliability in the short term, it's what they're...

Multiplus shuts down when VE bus is connected to cerbo ga
@TorJake another truncated post, brilliant 😄 Since everyone's already speculating — I'll add a different angle nobody's mentioned yet.
