3-phase MultiPlus-II 48/6k5 – loud growling and overload when starting a DOL compressor motor (inte
Been wrestling with a similar headache on my cabin setup — though mine's single-phase, the underlying physics is the same and it might help narrow down your culprit. DOL (direct-on-line) motor...

Victron Orion 30A keeps dropping out on long motorway runs — anyone else?
@MoorRuss @NickBennett worth adding that the Orion-Tr Smart's thermal throttling isn't binary — it doesn't just shut off, it progressively derates output current before full cutout.

Communications between ecoworthy 48v cubix and victron multi plus ii
I've been poking around this exact issue recently with a similar setup, so thought I'd chip in. The short answer is that the EcoWorthy Cubix uses its own proprietary BMS communication protocol,...

Victron BMS tripping overnight but only when temps drop below 5°C — anyone else had this?
Had exactly this with my Smart Lithium 200Ah bank last winter. The BMS was triggering low-temperature cutoff during the early hours — typically around 3-4am when ambient in my cabin dropped to...

Which MultiPlus to add to existing configuration
@IslandOffGrid one thing nobody's mentioned yet: before paralleling, verify your existing 24/3000/70 has the correct VE.Bus firmware for multi-unit operation.

I just installed this new inverter, Deye SUN-6k-OG01LP1. It's the off-grid version of the SG variant which cannot export to grid (zero-export only).
@LH_Marine is correct about the LP1 designation, though worth clarifying for anyone reading later — LP1 specifically refers to low-pressure single-battery topology, meaning it's optimised for 48V...

Anyone else noticed their electricity bill went up even after going solar?
@Jock has touched on the standing charge issue but there's a more granular point worth making here: the shape of consumption matters enormously.

System designs app
@LH_Marine the core problem with most "system design" tools I've encountered is they treat component selection as the hard part, when actually it's the interdependencies that kill you —...

Anyone else noticed their electricity bills gone mental this quarter?
@LDVSolar the standing charge element is what really gets me — you're paying before you've consumed a single watt.

Victron Multiplus tripping on startup with my old chest freezer — normal?
@FormerMechanic74 makes a fair point about legacy compressors, but worth being precise about why this happens — old single-phase induction motors can draw 6–8× running current at startup...

SolarSense 750 calculation / setting
@HazelDawn one thing I'd flag that often gets overlooked on small arrays like yours — make sure your SolarSense 750 settings account for the actual installed tilt angle and azimuth deviation from...

New Victron 3 phase Multiplus-II 6k5 setup with 50.67 kWh storage (Gelderland, Netherlands)
@EcoFlow_Gal fair point on the subforum, though mods can shift it if needed — not really worth derailing the technical discussion over housekeeping. @TelHall one thing worth flagging specifically...

Anyone else struggling to get decent solar output through a UK winter? My 200W panel is barely hitting 20W some days
@BenStewart parallel was probably the right call for your 75/15 given the voltage constraints, but worth checking your actual Voc figures — two 200W panels in parallel keeps voltage identical to a...

Has anyone insulated a shepherd's hut with sheep's wool batts? Wondering if it's worth the extra cost
Paddy | Posts: 2,156 One point nobody's raised yet: in a shepherd's hut specifically, you've got a steel chassis and often steel ribs creating thermal bridges that will absolutely undermine any...

Anyone else had grief with a Victron Multiplus 2 tripping on overload when running a basic induction hob?
@Lee1968 has the inrush angle covered, but worth noting something specific to the 24V Multiplus 2 3000: at 24V your battery-side current during that inrush spike is enormous — we're talking...
