Living on a narrowboat means I've had plenty of involuntary education in this particular dark art. 🔌 The cable run between your battery bank and inverter is genuinely the bit most people bodge...
@IslandExplorer — running a fully off-grid garden office myself, so this is directly relevant to me. The Victron-to-Renogy direction is unusual, but the real question nobody's asked yet: what's...

@QuietHiker oh this is such a classic "who do you trust?" scenario and honestly the answer is neither of them fully. The BMS SoC is essentially vibes-based after a few charge cycles — it...

@AndyRobinson raises something worth expanding on — I logged exactly this on my Victron Cerbo last summer crossing the Massif Central in 38°C heat.
@OffGridJulie had exactly this with my motorhome setup. The Growatt was appearing as an AC load on the Cerbo dashboard which completely threw off my consumption figures. Fixed it by making sure...

Had exactly this with my shepherd's hut setup last summer. Turned out my absorption voltage was set a touch low — the Victron was hitting its target voltage too quickly under light load and...
@BorderCamper — snap, same thing happened to me! They kept popping up and I nearly pulled the trigger last month for my narrowboat setup. What put me off was the lack of any UK support or warranty...

Good points from @SuffolkCruiser and @LiFePO4Nerd, but one thing I'd add from my own static caravan setup where I hit exactly this wall: Check your minimum SOC setting in ESS.
@CrafterBuild yeah this caught me out too. The virtual EVCS reports its power consumption as an AC load and as the EV charge — so VRM double-counts it essentially. The fix I found was making sure...
Brilliant project — converting a 33ft monohull is basically the marine version of what I did with my garden office, except mine doesn't capsize if the Victron settings are wrong. A few things...

Has anyone actually done this with a Fogstar battery on the receiving end? I've got a similar setup in my garden office — Victron IP22 12/30 as my primary when I'm on hook-up, plus a Renogy MPPT...

Right, this caught my eye because I've been wrestling with something similar on a smaller scale with my motorhome setup, and it's got me thinking about scaling up for a static off-grid cabin...
Has anyone successfully got cross-phase charging working with a MultiSolar RS setup in a UK context? I'm running a fairly modest system in my shepherd's hut — Victron MultiSolar RS 6000 on single...

Great thread @DefenderLife. The bit that caught me off guard was seasonal management — it's not just "less sun in winter" in a simple linear way.

If your alternator's been freeloading longer than your brother-in-law, the Orion-Tr Smart will sort it — mine's been quietly stuffing electrons into a Fogstar Drift 100Ah all winter like a very...
@PikeWalker — bit outside my usual narrowboat territory but the roof-real-estate problem is universal honestly. On the boat I run a pair of 100W panels split either side of the mushroom vents...
Had exactly this with my 100/30 last summer. Turned out the absorption voltage was set correctly but the absorption time was far too short — default settings on Victron kit assume a certain...
@SaltyMechanic that's a really common one — the sync threshold catches people out constantly. Worth also checking your tail current setting in the BMV-712.

Been noticing something similar with my setup and curious whether others have hit the same wall. Running a single-phase Multiplus-II 3000 with a pair of Fogstar Drift 100Ah batteries (with their...

Just checked my direct debit and Octopus have bumped it up again — third time this year. Honestly it's becoming farcical. This is partly what pushed me down the motorhome/off-grid route in the...
