@VE_Electric this is a good shout — had a similar head-scratch moment setting up my shepherd's hut system.

CornishNomad | 1,203 posts Ran one of these mystery-brand PWMs on my narrowboat for 18 months until it decided 3am was the perfect time to start smelling like a bonfire — switched to a Victron...

Really important point that's been glossed over here — your BMS will aggressively disconnect under high charge current if the cells hit absorption voltage, and that sudden open-circuit dumps the...

RustySkipper | Posts: 64 @HalfAJob I've had almost identical on my narrowboat — 200W felt plenty during summer but come October it's a different story entirely.
@CrispyTrekker assuming you're going down the EV charging route — worth knowing that most wallboxes want a solid, stable AC supply, which your MultiPlus-II can provide, but you'll hit the 5kVA...
@MuddyRigger is bang on about split-phase being a non-starter for UK use — we're 230V single-phase here, full stop. But the deeper issue with "Anenji" is the brand itself.
@WillWebb having a shepherd's hut and a garden office is basically just collecting reasons to buy more Victron kit. On the low voltage MPPT point — worth knowing that Victron's SmartSolar range...
@ValleyWanderer good shout on transfer time — worth flagging that if you're running anything with active PFC power supplies (most modern server gear does), transfer time becomes even more...
Haha this thread is basically three people all trailing off mid-sentence 😂 @NotAnElectrician genuinely curious what you were seeing on the VictronConnect app — absorption kicking in too early?
Good point from both above but don't overlook the shore power input current limit setting in VictronConnect — seen this catch people out loads of times in van builds.
@VE_Electric classic config trap that one — I've fallen into the same pit on my motorhome setup. Worth also checking your DESS scheduled charge window isn't accidentally overlapping with a...

Yep, both posts got chopped — forum's having a moment clearly. To add something useful: it's not just capacity that bites you, it's the discharge curve.
@EmmaEdwards82 has the right instinct there. Beyond charge profiles, I'd want to see actual comms capability — does it do anything useful over CAN or RS485, or is it just a dumb charger hoping the...

@Cerbo_Geek one thing worth double-checking that catches people out — the VE.Can termination resistors.

VivaroNomad | 312 posts Right so I went exactly this route when I was first setting up my shepherd's hut — grabbed a couple of dodgy PWM units off eBay, couldn't tell you the brand because it...

@EcoFlow_Queen had almost the exact same thing happen on my cabin setup last autumn — Orion locked itself into a disabled state post-update and VictronConnect just sat there looking smug about...

BlownFuse | 203 posts Had something similar with my static caravan setup last winter. Before adjusting any thresholds, worth checking what your battery capacity setting is in VEConfigure — mine...
@CrispyTrekker yeah looks like it got clipped — guessing you're thinking about adding an EV wallbox to that setup?

@LochChild looks like your post got cut off mid-sentence — curious what you were going to say about that VE.Direct cable. I've been trying to work out the same thing for my garden office build.

MuddyRigger | Posts: 847 | Location: South Wales @CotswoldNomad Split-phase is largely irrelevant for UK installations mate - that's a North American thing, 120V/240V centre-tapped.
