@DownsCamper the Lynx Distributor's power indicator is purely a "is there voltage present" lamp — it's not telling you anything clever about current flow.

@FenlandSolar @DailySolar are both right on the BLDC point — I found this out after pulling apart a Bosch drum thinking I'd struck gold. One thing nobody's mentioned yet: rectification.

Been dealing with this exact issue with my shepherd's hut setup rather than a van, but the physics is identical so worth chipping in. The short answer is yes, and it's worse than most people...

RobBennett93 | Member @LutonAdventure for a static caravan you'll likely be fine as long as the shunt is the only negative connection point — everything else should star off the battery negative...
Ran mine through a logic analyser last summer out of sheer motorhome-related boredom — the load output does a brief voltage sense before switching the MOSFET, which is why you sometimes see a tiny...
Been down this rabbit hole myself recently with my cabin setup — pulling data from the Cerbo GX via Modbus TCP to feed into a Home Assistant dashboard, and the register values were consistently...
Had this exact head-scratch moment when I was commissioning my garden office setup last autumn. Measured the neutral and nearly convinced myself something had gone catastrophically wrong. Short...
Anyone else noticed their Multi-RS behaving like it's suddenly forgotten what "self-consumption" means after a firmware update? Rolled out v1.31 on my setup last week and now it's...
@Davo51 On the boat I'm largely insulated from this (pun intended, sorry), but I do maintain a small grid-tied emergency backup setup at my storage unit and the standing charges alone are...

@RustyTinker "magic smoke" is just the inverter giving you a free aromatherapy session, to be fair. I've got a Victron Multiplus on the narrowboat and yes, it cost enough to make my eyes...
@CarlWalker this one took me down a rabbit hole on my motorhome last February. Turned out my Victron BMV-712 had never done a proper full synchronisation cycle — the 100% reference point was...

@Macca I'd push back slightly on the framing — the "dodgy Chinese knock-offs" narrative gets thrown around a lot but plenty of the Tier 1 stuff (JA Solar, Longi, Risen) is...

Had a similar head-scratch moment when I first powered up my Victron setup in the van last spring. Everything was working — MPPT charging away, loads drawing current — but the Lynx Distributor...

Been through something similar with my van build — but in my case it turned out to be the battery temperature sensor placement rather than the BMS itself.
@Cleggy interesting one this. I'd add something nobody's mentioned yet — BMS communication latency. On my motorhome setup I run Fogstar Drift cells with a JK BMS, and I noticed DESS was making...

Good timing on this thread — I looked into this exact thing a few months back when I was trying to figure out why my phone was still charging overnight despite the load output switching off. To...
@BlownFuse worth knowing that for a static setup you won't have this problem at all — no engine, no alternator, no heat-related voltage sag.

@MarineFrank curious whether you noticed any difference in how the Sterling handles the transition between shore power and inverter mode?

The linear drop pattern on MPPT trackers is almost always one of two things: partial shading creating a false peak on the IV curve (tracker locks onto secondary peak), or — and this caught me out...

Really glad @FenlandSolar is raising this — it's something I learnt the hard way last year. To add to what @DailySolar is hinting at, even once you've confirmed you've got a BLDC motor, the...
