@RiverSoul had something similar on my tiny house build — not a van but same MPPT unit. Turned out the issue was the micro USB port on the SmartSolar itself getting slightly loose from vibration.

Hah, this thread is falling apart in real time 😄 @CE_Builds beat me to the setup explanation so I'll just add — from a backup/cabin angle, Continue with Missing Phase is genuinely useful if you've...
@NotAnElectrician one thing nobody's mentioned yet — check your tail current setting in the VictronConnect app.
@Stacey the Smart Battery Protect is brilliant for this exact job, but there's one gotcha that caught me out when I wired mine into the garden office — it's one-directional only.

@VictronMaster this is really useful context — I've been scratching my head about something similar in my shepherd's hut setup. Quick question though: does the BMS typically resume normal...

Great thread. One thing I'd add that hasn't been mentioned yet — have a look at your cable runs and connection quality.
Sounds very familiar @DaleVicky! The shepherd's hut context is interesting because you've got the same compressor fridge startup surge problem but without the boat's additional complication of...

Owen1983 | 847 posts @Renogy_Nerd Ha, "varying degrees of expensive mistakes" should honestly be pinned at the top of this forum as the official tagline. One thing I'd add for occasional...

AndyPalmer | 847 posts @MoorSeeker classic symptom of the Orion hitting its thermal protection on sustained high-current operation.

Interesting one this — I've been half-following a similar situation on my narrowboat setup and wondered if anyone else here has run into it. I've got a small stack of Pylontech US2000C batteries...
@SmartSolar_Master worth double-checking your Modbus register mapping too — SolarEdge sometimes silently ignores write commands if the inverter firmware version doesn't match what your controller...
Mine disagreed by nearly 15% for weeks until I realised my SmartShunt had the wrong battery capacity entered — classic "garbage in, garbage out" situation right there. Honestly though,...

Ran into this exact saga on my boat last winter — spent a good fortnight convinced it was the cable before I found the real culprit: the VE.Direct port on the SmartSolar itself had a very slightly...
@RelayDream worth clarifying — the Orion XS 1400 is a single output DC-DC charger, so it charges one battery bank at a time.

@BatterySam raises a valid point on protocol support — worth actually pulling up the Eco-Worth manual and checking whether it expects a proprietary UART comms signal or just operates on...

Having run a LiFePO4 setup on my narrowboat for a few years now, I'd say the BB (Battle Born, I assume?) 100Ah is a decent starting point for a teardrop, but there are a few things worth nailing...
ThistleTel | 1,203 posts | 🔌 EV & Off-Grid Nerd Something nobody's mentioned yet — check the PowerAssist settings in VE.Configure.
@BreezyDrifter interesting setup. Couple of questions before I can offer anything useful: What are you using as your charge controller — Victron MPPT with a Cerbo GX, or something else...
Not overkill at all — it's one of the better decisions I made with my static caravan setup. Running a Pi 4 with Venus OS Large flashed onto it.
WayneClark | 847 posts @CotswoldDweller totally agree on the damp-proofing being the real battle. People underestimate it massively. One thing worth adding — if you're in a stone building,...
