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...

@LindaClark90 good timing asking that — the actual spec matters enormously here. From my van build I learned this the hard way: your inverter/charger needs to be the single source of truth for the...
@GrumpyWanderer had this on my narrowboat Multiplus-II last winter. Bricked mid-firmware update, not even a config change — just a dodgy laptop going to sleep at the wrong moment. Recovery mode...
Been genuinely surprised this past week or two. My cabin setup has a pair of 200W Renogy panels on a south-facing roof, and the Victron MPPT is logging some decent numbers — way better than I'd...

Been lurking on this thread for a bit and finally have a reason to chip in. Got an old 60V e-trike I picked up secondhand and I've been wanting to add a small solar top-up for when it's parked up...
Gave up on the grid bill the same way I gave up on bricklaying — slowly, then all at once, then with enormous relief.

Had this exact behaviour with my 100/20 on the shepherd's hut build last autumn. Turns out it's almost always one of three culprits: 1.
@TracyMitchell had the same head-scratcher with my Fogstar 100Ah last spring! One thing worth checking that nobody's mentioned yet — the tail current setting in VictronConnect.
Been mulling over a similar topology for my tiny house emergency backup setup and thought it worth raising here. My primary bank is a 200Ah Fogstar Drift LiFePO4, charged via a Victron SmartSolar...

@TIW_Power I've got a mate running one of these "never heard of 'em" Chinese inverters in his cabin build and three months in it's either going brilliantly or he's just stopped answering...

@Wez1961 worth checking the absorption/float voltage settings too — if someone's previously set the charger profile to something like 14.4V absorption but your battery BMS is cutting out at 14.2V,...
Good topic — this came up when I was wiring my motorhome's secondary battery bank a few years back. @CaddyProject has touched on the key issue: without a proper varying-voltage input (like a solar...

Really useful thread — following closely as I've got the same unit in my motorhome. One thing I haven't seen mentioned: have you checked your battery voltage under load?
Something I've learned the hard way with my tiny house setup: the VRM portal sections don't always populate automatically just because the devices are connected — they need to be correctly...
@SomersetVanLifer has a point worth finishing though — diffuse irradiance still matters, and actually where your panels are pointed becomes disproportionately important in these conditions. My...

Really interesting thread for my van/boat research too. @DailySolar's "two kings" analogy is spot on — but has anyone looked at whether the Multiplus could be configured purely as a...
@BirchRunner worth checking your BMV's Peukert exponent and charge efficiency factor settings too — defaults are often wrong for LiFePO4.

@GrumpyWanderer had this exact situation on my shepherd's hut build — genuinely thought I'd killed a brand new Multiplus 12/3000. What actually saved it: holding the rocker switch on the unit...
LizStewart | Posts: 312 | Location: Array The thread title's in French which is a bit odd, but anyway — the Enphase + Victron combination is genuinely worth thinking through carefully before...
