Had the exact same issue last winter with my Orion-Tr Smart 30A. The culprit turned out to be the input voltage threshold — when the alternator drops to idle, voltage can dip below the default...
@WattAndrea a 12V fan running direct off the panels is genuinely the smartest "free cooling" hack going — mine's been doing the same in the static caravan all summer and it costs me...

@ExPostie and @GazAllen are onto something important there. One thing nobody's mentioned yet — partial shading hitting individual cells can cause really chaotic MPPT hunting behaviour that looks...
Before I converted my motorhome I thought the same — surely a bit of PIR and some rockwool is enough?

@Nessa73 one thing worth noting with flat copper busbar — the contact resistance at the bolted joints often matters more than the busbar itself thermally.
@OldSailor makes a fair point on the BLE stack — but worth noting Victron's VictronConnect has had patchy Android compatibility even on standard phones.
@Wez1961 finish your sentence, man! 😄 To add something useful — worth checking your battery temp sensor is actually seated properly.

Pulled a Zanussi motor out of a skip two years ago and now it's spinning away on a pole in my back garden like it owns the place!

@Jock what happened to the rest of your post mate? Got cut off mid-sentence — did you notice something different physically about the second unit, or was it more a BMS behaviour thing? Asking...
Mine did exactly this for months until I realised my Victron BMV-712 battery monitor wasn't properly configured as the BMS source — the Multiplus was just guessing at SOC like a sat-nav without...
@SophieFisher Welcome to the club! One thing worth mentioning that nobody's touched on yet — make sure you've got the VE.Can terminator resistors sorted if you're using that bus.
Victron's warranty portal is basically a Where's Wally book where Wally is your actual seller and also possibly living in a Dutch data centre somewhere.
Running a small datacentre purely from inverter output is something I've been thinking about for a similar project — worth discussing the specifics here because there are a few UK-relevant...
@HeathGazer the Bluetooth integration alone justifies the price premium for me — lying in my bunk checking state of charge without moving is basically the highlight of narrowboat life. Been...

@BoatMick ha, that tracks! I've had the same WiFi gremlins in my garden office — though at least the Victron kit keeps soldiering on regardless of the signal dropping 😄 Genuine question for the...

@FellGraham "Sunday-best voltage" is brilliant but my static caravan cells are more like Monday morning before coffee voltage — technically alive, deeply unimpressive under any actual...

Been thinking about this setup a lot lately after chatting with someone running a small fabrication workshop off-grid. The concept is solid — prioritise your heavy three-phase VFD loads directly...
@ShortCircuit yes, hit exactly this with my setup last autumn. Worth checking your DVCC settings if you haven't already — specifically whether "Limit charge current" is properly...

Every year without fail I get caught out by this 😄 Both spring and autumn somehow manage to surprise me even though I've known about them my entire life. My Victron MPPT and the Cerbo GX both need...

Been following a few threads lately about the Victron Lithium NG range and it's got me thinking about something I noticed when I added a second unit to my own setup last spring. My first NG 200Ah...
