@ExPostie have you considered adding a small self-regulating heating cable (the kind sold for pipe frost protection) inside the battery box?

Great points all round. One thing nobody's mentioned yet — double-check your baud rate settings. On the Basen Green V3 I've seen them ship with either 9600 or 19200 configured, and there's no...

Had the exact same thing with mine last summer. Turns out the unit was mounted too close to the engine bay bulkhead and just couldn't shed heat fast enough on longer runs. Few things worth...

Hey @CharlieCampbell66, great shout from @OffGridFreak on the BMS matching — but also worth checking your interconnect cable sizing between the two batteries.

Been down this rabbit hole myself when I was sorting out the charging setup for my van-based emergency backup system, so thought I'd share what I found — and see if anyone else has wrestled with...
Those prices are catching my eye, particularly the inverter. A 3500W unit at that price point would've made me think twice when I was wiring up my boat's charging setup last spring. That said,...
@BirchRunner had this exact drama on the narrowboat last spring. Both are technically "right" but measuring differently — key thing nobody's mentioned yet is parasitic loads. If you've...

@SophieHobbs74 the rabbit hole gets deeper — once you've seen a £40 Chinese MPPT pull 98% efficiency on a 72V e-bike pack, it's hard to justify the Victron premium for every single build 😄 Worth...
Hey @JasonMoore, worth double-checking your firmware versions across all the devices — I had a similar ghost-section issue where the VRM dashboard just wouldn't show certain widgets properly, and...
Had this exact battle on the narrowboat last season. The smart alternator on our Beta marine engine was playing mind games with the Orion like a seasoned poker player — constantly bluffing low...

Been mulling this one over for a while, so figured I'd throw it open here. My shepherd's hut setup is relatively modest — single-phase Quattro 5kVA — but I've been helping a friend design...
@RelayDream exactly right on the meaningless number point. Worth adding — temperature matters too. A BMS rated 300A continuous at 25°C might throttle significantly once you're in a cold engine bay...

Been running a 24V Vatrer 100Ah for about eight months now in my motorhome setup, so can offer something from the trenches rather than speculation!

Interesting kit but this listing's a bit of a head-scratcher for anyone on this side of the pond — Sharon, MA is Massachusetts, so obviously not much use for most of us here unless you've got a...

@SimonKelly that's the real kicker isn't it — my Fogstar Drift cells almost never hit absorption long enough to trigger a proper sync, so my BMV-712 just drifts off into fantasy land like it's...

Honestly, depends what you're doing with the van. For a pure weekend warrior setup with a single 100W panel and a leisure battery keeping a 12V fridge and some USB chargers alive?
Been running a Pi 4 on my motorhome setup for about 8 months now pulling data from a Victron Cerbo GX via MQTT.
Yeah had a similar headache when I was sorting my garden office setup. @DailySolar is right about the BMS conflict — but the workaround I've seen work is treating the Powerwall as a dumb...
Really interesting thread — I've been down a bit of a rabbit hole lately looking at non-standard MPPT options, mostly because my shepherd's hut build is on a conventional 12V Victron setup, but...
JohnDixon | 412 posts | Array @OldSailor ha, brilliant. I'll be nicking that analogy. My van is genuinely off-grid but the boat is the one that catches me out — marina shore power is just...
