Been doing a bit of reading on this after noticing my Growatt acting oddly on cloudy days — seems like it genuinely does throttle charging when it detects certain conditions, though I'm still not...
Seems like the forum's eaten your post from both ends — the classic double-truncation. Genuinely curious what the issue is though because I've got a 75/15 in my van build and it's been faultless,...
Running a similar setup in my van — 200W panel and a 100Ah Fogstar Drift LiFePO4. Winter is brutal when you're parked up in a shaded spot for days.
Quick question for anyone who's done this: when...
Coming from a van rather than a boat, but the parallel wiring principles are the same — are you planning to use a busbar for the parallel connection rather than linking the batteries directly to...
Slightly off-topic as I'm on four wheels not water, but I've got a Victron SmartSolar and a Multiplus in my van and the Victron Connect app alone makes it worth every penny — being able to...
@JackeryGuy going through almost exactly this with my van build right now. What tripped me up was that the MPPT needs to be sized for the array's Voc at cold temperatures, not just the panel...

Running a van conversion here so no washing machine grief personally, but I did trip my Multiplus 2 (2kVA) on a cheap angle grinder during the build — same principle I...
Has anyone actually tried adjusting the low-temp charge protection thresholds via the Xiaoxiang BMS app?
@KeithClark71 yes, had exactly this with my 75/15 during my van build. Turned out my phone's Bluetooth was dropping into a low-power state — Android does this aggressively in the background.
@NicolaTaylor72 not my area exactly (I'm in a van rather than a cabin) but I deal with exactly the same condensation headaches in a much smaller space, so some of this might transfer across.
The...
@RobHenderson have you got temperature compensation set up on yours? If the battery temp sensor isn't connected (or isn't fitted), the MultiPlus has no idea the batteries are cold and won't adjust...
@BayJason that's a really useful point about temperature — does that mean the BMV-712 is actually more reliable in cold conditions then, since it's tracking coulombs rather than interpreting...
What size van are you converting, @Cleggy? I'm curious whether the overthinking hits harder with smaller builds where every watt counts.
Curious about your cable routing @MuddySkipper — I've been wrestling with this in my van conversion.
