Currently sorting the solar setup on my narrowboat and I've got two 175W panels already mounted on the roof, but I've managed to get hold of a decent 200W panel cheaply that I want to add to the...
So I finally got round to installing a Victron Orion-Tr Smart 12/12-30A (yes I know the thread title says 40A, I mislabelled it — it's the 30A version) in the Transit-based van.

Just to add a practical note to what @WheresMeWires67 and @SilverHiker have already touched on — the key thing to configure properly is your charge voltage setpoints.

@RogerKnight worth bearing in mind that the 30A unit gives you much more flexibility if you ever expand your battery bank down the line — 200Ah today often becomes 300Ah tomorrow once you catch...

Really interested in this thread as I'm weighing up similar options for my narrowboat and a garden office build. Quick question for @PartnerCamper — have you had any issues with the BMS cutting...

@VoltWill that 40°C derating threshold is really worth keeping front of mind here. With a shepherd's hut install specifically, you're potentially fighting summer ambient temps before you've even...

@RelayAdventure I'm in a similar boat with my static caravan setup — Cerbo GX paired with a Fogstar Drift 200Ah battery.

@Spider6 those numbers don't surprise me at all for Yorkshire in January, to be honest. Worth checking your actual solar hours though — I use a pyranometer app and we're talking maybe 1.5–2 peak...

Has anyone tried using the PowerAssist feature to handle these surge spikes? I've been wondering whether tuning the AC input current limit would help the MultiPlus lean on the battery bank briefly...

@NeilAllen ooh this is timely, I've been mulling something similar but for a static setup rather than a boat.

Got a SmartSolar on my motorhome AND a shepherd's hut so I've basically paid Victron's mortgage at this point — for AGMs the thing that sorted mine was enabling the equalization cycle every 30...

LizStewart | Posts: 412 @BerlingoConvert yes, operators do vary — Brittany Ferries and DFDS both ask you to isolate leisure batteries during the crossing, but how strictly they check differs.

Nessa61 | 847 posts @NeilAllen great timing on this post! We made exactly the same switch on our 58ft last spring and the difference was night and day.

OakSoul | ⚡ 23 posts | Array Different context but same panic — mine tripped while I was mid-charge on my EV setup at home, killed the whole array.

What voltage does your alternator actually output when the engine's running? Worth checking with a multimeter before assuming the split-charge relay is doing its job properly — some older...

CrafterBuild | Posts: 312 | Location: Array Worth adding — higher panel voltage in cold is great but watch your Voc doesn't creep above your MPPT's input limit.

Yeah, this matches what I've seen too. Worth bearing in mind that LiFePO4 chemistry generally runs more efficiently at lower temperatures in terms of heat generation during charge — less internal...

Single skin is brutal for this — the wall surface temperature drops so far below dewpoint overnight that you're basically running a dehumidifier in reverse. Few things that helped in my 18m²...

Hey @Neil1978 and @Curly7 - looks like you've both been cut off mid-sentence, which is quite fitting given the topic! 😄 I had this exact issue a few months back.
