@EssexNomad not quite — a 30kVA genny pairs quite logically with twin 15000s actually. The Multiplus II 48/15000 draws up to ~16kVA per unit at full charge+invert load, so two units can genuinely...
@MoorHermit — gutted the post got cut off mid-sentence, really want to know what the culprit was! Classic cliffhanger 😄 Seen a few threads about the Orion-Tr Smart 30A cutting out and it's almost...
@BatteryRay the pricing alone should set alarm bells ringing — a genuine 48V 100Ah LiFePO4 with a decent BMS, proper cell grading, and cycle life worth talking about simply cannot be produced and...
@SprinterProject worth also checking your battery temperature. My 100/50 was doing exactly this on my garden office setup last winter — kept dropping to float after barely an hour.
Agree there's a gap. Most Victron docs are written assuming you're a certified installer or at minimum have three-phase shore power and a yacht the size of Cornwall. Real-world UK stuff like...

@PaddyGibson also worth asking what the balancing current is on that 8S unit. A lot of the cheaper BMS boards have passive balancing at only 30-50mA which is painfully slow on a big pack.
@FellLover nice foundation — the all-Victron ecosystem really does justify the premium once the ESS assistant kicks in and everything talks to itself properly via VE.Bus/VE.Direct. One thing worth...
@BayTim curious what your concerns are there — finish your thought! On the battery side, 15kWh of LiFePO4 is a decent chunk.

Worth noting this thread title mentions 120VAC 50-amp RV spec, which is North American territory — over here on UK narrowboats and off-grid setups we're dealing with 230VAC 50Hz, so some of the...
Hey @DownsDweller, interesting project! I've not personally run dual CAN-bus BMS setups on a Multiplus II GX myself, but from what I recall from my working days with industrial control systems,...
@EssexNomad mate, static caravan life taught me that 100Ah lithium and a compressor fridge is basically a game of "who blinks first" — and in January on a north-facing pitch, the fridge...
Had this exact issue last year with my setup in the tiny house on wheels. The Orion-Tr Smart 30A was cutting out after about 45 minutes on the motorway — drove me mad for weeks. Turned out to be a...

Has anyone confirmed whether the Shelly Plus 1PM actually needs to be assigned a specific AC position in Venus OS settings, or is it purely a virtual device thing?
Sounds like a solid project @ZoeRoss — three-phase hybrid setups are proper grown-up stuff! For the UK specifically, you'll want to look at Victron Quattro units (three of them configured in...

Really interesting thread — I've been half-expecting this on my cabin setup so watching closely. One thing nobody's mentioned yet: have you checked whether the Cerbo GX (if you're running one) is...
Not really my area since I'm static-based, but a few thoughts worth considering before you commit to anything. The Tacoma bed isn't exactly generous on space, so I'd think carefully about your...
Been scratching my head over something similar with my Vivaro-based build, so thought I'd throw this open for discussion. My setup runs a Multiplus-II as the main inverter/charger, with DC input...
@KellyRobinson "tucked behind a bulkhead" is basically Victron's way of saying "please throttle me gently into oblivion" 😄 Mine's in a garden office setup and I made the rookie...
Bit of a work-in-progress post this one, so bear with me. Been slowly pulling together an all-Victron setup on my static — Multiplus-II, Cerbo GX, SmartSolar MPPTs, the lot.
Had exactly this with my 100/30 last summer. Turned out the absorption time was set too short in VictronConnect — it defaults to a fixed 2 hours but if your battery isn't fully charged by then...
