So I've been running a MultiPlus 12/3000/120 in my off-grid shed setup for about eight months now and kept getting random shutdowns whenever I fired up my table saw (roughly 1800W running, but the...

@PikeTom two 12v systems in one build — so you've essentially reinvented the narrowboat, welcome to the club 🚢

I've been fitting a Victron Orion-Tr Smart 12/12-30 in my Transit-based camper build and I've gone back and forth about whether to use it in isolated or non-isolated mode about five times now.

Been scratching my head with this for a couple of weeks now. Running a 24V system with 200Ah of Battle Born LiFePO4s and a MultiPlus 24/2000/50.

CamperRachel | 89 posts @Megan1960 Worth bearing in mind that cold temperatures actually boost panel voltage — Voc rises as temps drop, so if your panels are rated at say 24V open circuit at STC...

TorDweller | Posts: 1,204 Running a very similar setup on my narrowboat — Orion-Tr Smart 12/12-30 feeding a Fogstar Drift 100Ah lithium.

Rolled out the v3.20 firmware on my SmartSolar 100/30 last Tuesday and now it's throttling back to about 40% output on perfectly clear days — sitting at 180W when my two 200W Renogy panels should...

@BoatMick sounds like you've made a solid start there! I went through exactly this with my static a couple of years back and honestly, yes - go bigger from the start if you can.

@TracyPrice64 worth checking your BMS discharge rate limit before anything else — Winston cells are decent but the BMS often ships configured conservatively, sometimes as low as 80-100A...

Paul1999 | ⚡ Regular Contributor @LutonAdventure Worth knowing that the low-temp protection only blocks charging on most LiFePO4 — the battery should still be able to discharge even when cold.

@DalesWanderer same here — curious what loads you're actually running. My garden office setup pulls around 400-500Wh daily (monitors, laptop, a bit of heating).

Reply by MandyPalmer56: @Ian1968 Something worth looking at that hasn't been mentioned — check your BMS communication cable connections, particularly if you're using the UART port for the app.

HarbourSam | 847 posts @IslandExplorer Eight months in is actually a decent point to reassess — you've got data across the seasons which is gold.

Good shout on the Fogstar Drift cells — solid choice. One thing worth flagging that nobody's covered yet: inter-cell busbar torque matters more in a van than a static install.

Great thread! @FinnRobinson, one thing worth considering with that setup is communication between your DC-DC charger and the MPPT — if both are pushing into the battery simultaneously without...

@Ben1960 18 metres of armoured cable is basically a Tuesday afternoon job for any half-decent sparky — solar's brilliant but if you're already wiring it up anyway, grid-tied means kettle and...

Just to add some numbers to what @FormerTeacher is getting at — I ran a similar 200W Renogy flat on my Transit last winter and was lucky to see 2–3A on a grey December day in Yorkshire.

Hey @DontPanic44, worth checking whether your battery monitor's shunt is positioned correctly — it needs to be on the negative terminal with absolutely everything else on the battery side of it,...

LesCrane90 | Posts: 312 @BordersSolar great setup! Just to add to what @ColJames74 was getting at — LiFePO4 cells really don't like being charged below about 5°C, even if they'll happily discharge...
