@FormerTeacher what's the mundane thing you're ruling out then — loose MC4? Because yeah that'll do it, had exactly that on my static.
Had exactly this on my narrowboat a couple of seasons back. The Orion-Tr Smart 30A was throttling back on longer canal runs — anything over an hour or so and it'd drop to a trickle then cut...

Really interesting to see this making its way into the Venus beta — has anyone actually got this running yet with a real HV battery stack in a UK setup? I've been watching the Pylontech HV...
Good shout from @EssexNomad on the oil sensor — worth checking, but before pulling anything apart I'd also look at the air filter and cooling fins.
@NaeClue I've been running four 400W panels on repurposed BT tray for about 18 months now up in the Brecon Beacons — so proper exposed conditions.

Fused within 300mm of the battery positive terminal — non-negotiable, yet half the builds I've seen on here treat it as optional, which is how you get a motorhome-shaped bonfire. @VanGill is right...
Been doing this in the shepherd's hut for about three years. Few things nobody mentions: SD cards will die eventually. Run your OS from a USB SSD if you're serious about long-term logging.
SmartSolarNerd | Posts: 134 | Location: — Quick question nobody's answered yet — what's the actual MPPT voltage window on that thing?
Good point from @ForestBoater about ruling out the battery first. If it's a flooded lead-acid, pull the caps and check the electrolyte levels — a dry cell will drag the whole pack down overnight...
@VoltVicky don't bin the Sargent just yet — the EC176 actually has decent 12V load outputs you can tap into without fighting the whole loom.
@TinaHenderson same setup as me — shepherd's hut with a Pi pulling SmartShunt data. I went one step further and stuck Grafana on top of InfluxDB so I get proper dashboards.
@RockyMender been there, done it, got the half-assembled motorhome to prove it. 😅 The thing nobody tells you upfront is that Victron's docs are written for installers not owners — they assume you...
@BatteryTim fair point on the semantics, but I'd say the practical implication is what matters most for off-grid planning.

Running this exact stack in my motorhome — one tip worth adding: stick a good quality SD card in (Samsung Endurance Pro series is what I use), because standard cards hate the constant InfluxDB...
@DaveMoore70 Furrion kit is genuinely rare over here, so I get the temptation — but I'd pump the brakes. Had a similar moment eyeing up a Morningstar unit on a US listing last year.
@TracyAllen is on the right track. I'd actually go slightly more conservative — 3.60V cell OVP for daily cycling, saves the top of your cells long-term.

@AlanPalmer57 Worth clarifying what you're actually trying to achieve here — are both banks the same chemistry?
What @Wayne1980 and @PennineNomad haven't touched on is the round-trip losses stacking up in this topology.
The key detail nobody's mentioned yet is synchronisation drift — the BMV-712 relies on a clean 100% sync point (typically hitting absorption voltage with tail current below your configured...
@CamperClive slapped a cheapo PWM on the narrowboat secondary panel once — lost roughly 25% efficiency compared to my Victron MPPT and nearly cooked a battery connection because the terminals were...
