Running into something similar with my garden office setup and curious if anyone's had experience with this. I've got a Fogstar Drift battery bank with a Victron Cerbo GX, a couple of SmartSolar...
@Del mate the Multiplus sine wave is so clean you could serve it on a plate at a fancy restaurant 🍽️ But yeah — when solar's absolutely hammering in, your real enemy is probably the...
HighlandDweller | Posts: 847 @WheresMeWires31 For that kind of light-duty emergency backup use, a 200Ah lithium is almost certainly overkill, aye.

@LisaKelly66 worth checking whether the MPPTs have "External Control" showing in their VictronConnect status — if that's not appearing even after the Cerbo sees them, I've found the...
Not quite a garden office situation myself — I'm on a narrowboat — but the thermal management problem is basically identical and it's something I've been wrestling with for a while. South-facing...
Had this exact problem last winter on the boat. Three cells would just vanish from the JK display on mornings below about 4°C, then magically reappear once the cabin warmed up a bit.

Been running a similar setup in my motorhome for a couple of years now so picked up a few things the hard way 😅 My sequence that's worked reliably: Power-up: Battery bank first (let the BMS wake...
Something nobody's mentioned yet — string voltage planning matters just as much as controller matching when you're splitting arrays on a boat. On my narrowboat I made the mistake of spec'ing...
@MeadowDweller this is exactly the perverse dynamic nobody warned me about when I started down the off-grid path.
@RetiredEngineer86 interesting about the B2B — is there a particular amp rating you'd recommend? I'm wondering whether 20A or 30A makes a meaningful difference on a shorter run, say 15–20...
@ExJoiner9 The doubling of unit rates is what got me too, but what really stung was realising the standing charge had quietly crept up almost as much in percentage terms.
@CumbrianWanderer had exactly this on my motorhome build last year — Victron SmartSolar 100/50 alongside a Multiplus-I. The key thing nobody's mentioned yet is tail current.

Had exactly this with my garden office setup last winter. Old chest freezer compressors have a brutal inrush current — we're talking 3–6x the running draw for that fraction of a second when the...
Been mulling this one over myself actually, as I'm mid-way through a similar-ish upgrade on my motorhome — swapping out to a pair of Fogstar Drift 200Ah cells and adding a Victron SmartShunt...
Right, so this has caught me out twice now and I'm starting to wonder if anyone else has seen it. My setup is a bit different from a motorhome — it's a garden office with a MultiPlus-II...
Been wrestling with a similar grounding question on my van build and thought it worth raising here for the UK crowd, as I keep seeing conflicting advice across different forums. I've got a Victron...
Good shout from @VoltKev on the LIb setting — just to add, once comms are established the Growatt should display the Pylontech's SOC on the LCD.

TorDweller | Posts: 1,203 | Location: Array Had exactly this on my boat last spring — turned out the bilge blower was recirculating warm air right past the Multiplus intake.

@HUO_Boats makes a crucial point about wiring — and to build on that slightly, the Multiplus has its own internal voltage sensing, which is measuring at its DC terminals, not at your battery...
@Clive1999 with 200Ah lithium you're essentially asking two 30A chargers to fill a very hungry bucket — the maths works out fine but your Victron Orion-Tr Smart will only hit its rated 30A when...
