Running a fairly standard van build — 200Ah of lithium (Fogstar Drift 200) being charged from a 110Ah starter battery via the Orion-Tr Smart 30A in non-isolated mode.

@RobHenderson classic Victron doing exactly what it's told — your absorption voltage threshold is probably being hit earlier than expected because cold batteries have higher internal resistance,...

ThistleKen | 1,203 posts | 🚢 Narrowboat · 🚐 Van Conversion Running mine off a Pi Zero 2W tucked behind the Cerbo on the narrowboat — draws about 0.7W which matters when you're arguing with a...

Been running a 2018 Transit-based motorhome for three seasons now, and last month I finally pulled the trigger on a Fogstar Drift 200Ah LiFePO4 to replace the tired 110Ah AGM that had been limping...

ExpertSolar | 1,203 posts | ⚡ Off-Grid Specialist @AlexJones the culprit here is almost certainly your absorption voltage being set too low, or your absorption time being fixed rather than...

Really interesting thread — I ran into something similar fitting a SmartShunt into my garden office setup, not a Transit but the same principle applies. One thing nobody's mentioned yet: cable...

Haha @ShesBeRight that's painfully relatable 😄 Worth flagging for anyone following this thread — the Multiplus has that PowerAssist and transfer switch functionality built in, so before anyone...

I've got a fairly standard 200W panel setup on the roof of my Bessacarr (two 100W mono panels in parallel, going into a Victron SmartSolar MPPT 75/15), feeding a 100Ah AGM leisure battery.

Been running a Pi 4 in my garden office setup for about six months now, pulling data from my Victron Cerbo GX over MQTT and visualising it through Node-RED dashboards.

CrafterDream | 634 posts Worth adding the thermal mass angle here — a lot of small cabins have too little of it, so the stove fires up, the air warms quickly, then the whole thing dumps heat the...

Great points all round. One thing worth adding to what @CotswoldCamper was getting at — make sure your Quattro and Skylla-TG are both configured with identical absorption and float voltages,...

@FormerCop is onto something — cold alternator output can sag below the Orion's input threshold faster than you'd expect, especially on short runs before the engine's properly warm.

Great thread, loads of useful info already. One thing nobody's mentioned yet — have you checked the freezer's actual wattage rating rather than just the stated capacity?

Really useful thread — I've been wondering about this for my boat setup. Quick question for anyone who's done this: how does the Pi cope when shore power drops and you're running purely on...

Following on from what @SimonGrant was getting at — another thing worth double-checking is whether your CT clamps are positioned correctly on the AC input cables.

Been lurking in the marine section for a while but finally got something worth posting. I've recently been adapting some of what I learned building out my tiny house system for a mate's narrowboat...

@Ollie1981 those real-world numbers would be genuinely useful — so many of these budget inverters get tested under ideal bench conditions rather than the cold, damp reality of British winter. I...
Great summary from @PhilCrane — sounds like the diagnostic path is pretty well mapped out. One thing I'd add from my own experience with a near-identical setup: check your battery temperature...
@Curly63 the Zero 2 W is criminally underrated for this sort of thing — meanwhile I've got a full Pi 4 in my narrowboat drawing enough idle power to make my Victron BMV wince every time I check...

Picked up a JK BMS (the 2A active balancer version, 200A continuous) a few weeks back to pair with my 8x 280Ah EVE cells.
