@CaddyDream the maths is pretty workable actually. A Shoreline 60 typically draws around 35-45W when the compressor's running, but it cycles — usually around 30-40% duty cycle once it's up to...

Been having a bit of a nightmare with my VM3P75CT and wondered if anyone else has hit the same wall. Set it up last week for my garden office system — Cerbo GX, Fogstar Drift 200Ah on VE.Can B,...

@AlexHobbs the part that tripped me up when I wired my boat was realising the fuse is protecting the busbar and distribution wiring, not the battery itself.

Spotted this doing the rounds on a few Facebook groups too — seems like ECO-WORTHY have been pushing these hard lately.

Had a similar situation with my Victron Smart Lithium 12v 100Ah last year — got it installed in the static and started poking around in the Victron Connect app out of curiosity. Worth knowing that...

Had almost identical symptoms last summer with my garden office setup — turned out to be a loose MC4 connector causing intermittent resistance spikes.
@BenStewart makes a fair point about the 40% SOC pattern — worth checking your battery temp sensor readings in the Victron app during those cutout events rather than just watching SOC. In my van...

@WattHelen to add a practical angle — if you're documenting a UK garden office setup, your relevant compliance path is more about G98/G99 (if you ever grid-tie) and building regs/permitted...

@BigAl had exactly this circus with a secondhand MultiPlus on the narrowboat — the dirty secret nobody tells you is that Victron tie firmware update eligibility to the product ID and original...

Got a Fogstar 200Ah LiFePO4 sitting in my static and I'm trying to work out if it's enough to keep a small chest freezer running through the night without solar input. The freezer is a Shoreline...

@MarineGeoff is absolutely right that Venus OS Large is underrated, but I'll add the bit nobody warns you about — the SD card will kill you. Running InfluxDB or even just Venus OS with frequent...
Always a fun rabbit hole to fall down, this one 😄 So I've been nerding out on this lately while planning an expansion to my garden office array.
@VoltJohn had this exact gremlin in my motorhome build last spring. After ruling out the usual suspects, turned out my CANbus cable between the Multiplus II and the Cerbo GX had a dodgy crimp on...

Been having a similar head-scratcher with my van setup, though on a smaller scale — Quattro 24/3000 rather than the big 10kVA unit. I've got a Honda EU22i feeding into AC1 input, and every so...
@GrumpySpanner nails it on the alternator point — this caught me out badly on my own boat a few years back. Worth adding: check your cabling between the batteries as well as the fuse.

@WattCharlie the Victron's doing its best impression of a zombie — technically "dead" but still haunting your DC bus through the PV input side 🧟

Hey @Fiona1974 — glad you caught it before wiring anything up! The thing that catches a lot of people out with the Multi RS Solar specifically is that the Voc limit isn't just a warm-weather...
@KevScott that remote on/off pin approach is exactly what I've been eyeing up for my garden office build — but here's what I can't figure out: does the Cerbo relay output supply enough...

Been doing exactly this for about 18 months now on the boat. Started with a Pi 4 I had gathering dust, installed Venus OS Large on it and suddenly had a proper GX device without paying Victron's...
@StuKnight to add to what @CliffGazer said — when Bluetooth is actively connected and syncing, draw can spike briefly but we're still talking low single-digit mA at most.
