Hey @GoldenBodger — just to add to what others have said, have you checked the transformer torque screws on the unit itself?

@KangooWanderer oh don't get me started on this one... Running mismatched panels on the narrowboat for two seasons now — a pair of old 150W Renogy units alongside a shiny 200W mono I grabbed from...

Really useful thread this. To add another angle — if your non-Victron inverter has any kind of RS485 or Modbus interface, it's worth checking whether there's a community-built driver for VenusOS.

Really interesting to see how many of us have landed on the Multiplus-II as the centrepiece. Running a 24/3000 myself in a long-wheel-base Transit custom build on Exmoor — paired with 300Ah of...

@ValleyOffGrid great timing on this post! One thing that catches people off guard with the Drift specifically is how flat the discharge curve is — you'll get used to seeing 13.2-13.3V for ages and...

Running a Victron SmartSolar 100/30 with two 200W panels in series (open circuit around 48V) feeding a 200Ah lithium (LiFePO4) pack from a Chinese brand — BMS rated to -10°C but I keep mine in an...

DerekYoung76 | Posts: 847 | Location: Scottish Borders @GoldenGaffer Ha, I'm in almost the exact same situation — Fogstar Drift in the van, Smart Lithium on the narrowboat.

ExpertCamper | 1,203 posts @GillWard The thing that sold me on the Orion-Tr Smart was the isolated version — completely separates your leisure and starter batteries which is brilliant if you've...

@BrianKnight86 the alternator compatibility issue is the classic narrowboat lithium headache — your BMS will happily disconnect under full charge and the alternator spikes can fry your rectifier...

Picked up a SmartSolar MPPT 100/30 about three months ago and it's been brilliant overall — running a 200W panel on a 100Ah leisure battery in my Transit conversion.

Great thread — one thing nobody's mentioned yet is the fill factor difference between the two batches.

Finally got my Orion-Tr Smart 30A wired up in the van last weekend and I'm a bit unsure how to handle the overlap between it and my 200W roof panel going into a Victron SmartSolar 100/20.

@RelayBuild worth checking your busbar and cell terminal connections before anything else. Even slightly undertorqued terminals create enough resistance that under high discharge you get a voltage...

Solid setup @Davo2 — the EU22i is a proper bit of kit, very fuel-efficient at partial load which matters when you're running it for a few hours into a charger. One thing worth considering: if you...

Yeah, had similar on my static. Kettle + microwave is a killer combo — both have high inrush current on top of their running draw, so they spike well beyond their rated wattage for a split second...

TimGreen | 847 posts | ⭐ Regular @DustyWanderer good setup choice overall. The 30A draw is only about 21% of your alternator's rated output, so on paper you've plenty of headroom.

@Chris1977 and @DodgyRoamer have already covered the monitoring side brilliantly, so I'll just add — if your mate is serious about sorting it out, the first thing I'd do is bin that 2009 leisure...
