Really interested in this thread as I'm trying to figure out if I can do something similar for EV charging purposes — basically using a mixed array to feed a Victron MPPT and then into a battery...

@Rodney47 nice timing on this thread — I've been doing something similar for my garden office setup for the past year. Running a Pi Zero 2W rather than a full Pi 4, purely because the power draw...
DaleBen | 847 posts @MuddyRanger Aye, Scotland in winter is genuinely humbling for solar. 15-20Wh from 200W is about right for a flat-mounted panel under heavy overcast up there - you're...

@GrumpySparky don't overlook the BMS communication side — if your Fogstar Drift has a VE.Bus or CAN BUS port gathering dust, plugging it into the Cerbo/CCGX lets the battery tell the MultiPlus...

DevonDweller | Posts: 2,847 @IvyWalker — static caravan and narrowboat use-case is almost identical to my own setup, so I can speak directly to this. The key thing with second-hand Victron is...

Been running a 400W panel setup on my static caravan for about 18 months now, mostly managed fine through spring/summer, but last winter was a bit grim.
@MoorRoger good shout on the Voc — caught me out on my narrowboat setup, nearly smoked a cheap PWM controller first winter morning when the panels were stone cold and everything was frosty.

@BordersOffGrid interesting thread — I'm running a MultiPlus-II 24/5000 primarily for EV charging integration, so passthrough mode gets used quite heavily when grid-tied. One thing worth flagging...

HarbourKate | 📍 South Coast | ⚡ Victron + Pylontech setup @BevOliver I had almost identical behaviour on my boat installation last summer — Samsung phone too, which makes me wonder if there's...

@BlownFuse finish that sentence — you've cut off before the actual number! Rookie trap though: most people underestimate by 30–40% because they forget parasitic draws (fridge compressor cycling...

@CallumHamilton83 did your post get cut off? Curious what the actual symptom is — are you seeing the MultiPlus drop to float before the batteries are genuinely full, or is it more that the...

@ExPostie82 To add to what @NaeClue13 said — worth checking what low-temp cutoff threshold your specific BMS is set to, as they vary quite a bit.

DawnJones74 | 📍 South Wales | ⚡ Off-grid since 2019 @OldSailor congrats on pulling the trigger! The Drift really has shaken up the budget end of the market.

Currently running a Victron Orion-Tr Smart 12/12-18A between my van's starter battery and a 100Ah Fogstar Drift LiFePO4 in the static.

@SolarJunkie @24V_Queen this is exactly what I'm trying to figure out for my garden office build. I've got a similar cheap PWM setup at the moment and I'm wondering whether the efficiency gain...

Had almost identical grief last winter with my static caravan setup. The penny dropped when I noticed my SmartSolar was consistently reading 0.3–0.4V lower than the Victron BMV-712 sitting right...
Same thing plagued my van build for most of last winter. Turned out the culprit was the VictronConnect app version on Android — there was a period where certain builds had rotten BT stability,...

JennyWilson | 47 posts @BigAl27 nice setup! I've got a MultiPlus-II 48/3000 in my shepherd's hut and honestly it's been brilliant.
