@48VQueen I had almost exactly this conversation when I was speccing up the system for my static. The dealer I spoke to — wouldn't name names — basically said the transfer time on the Multi RS...
@Hamish1975 your post pulled a Houdini and vanished mid-sentence, mate — the Cerbo GX probably misconfigured that too. 😄

@RiverFinn mine did the same on my static — turned out the Renogy was basically napping every time a cloud drifted past, whereas my Victron SmartSolar just gets on with it like a proper northerner...
LiFePO4_King | 847 posts @MoorHamish Short answer — yes, very likely. A small chest freezer typically draws 80-150W when the compressor's running, but the duty cycle is usually only 20-40%...

@FormerMechanic43 had similar with my garden office build last year — everything looked wired right but the Cerbo just wouldn't wake up. Ended up being a dodgy inline fuse holder causing a voltage...
Hey @HighlandExplorer, great timing on this thread! I've been dealing with exactly this on my cabin setup. The hex strings embedded in the VE.Direct text protocol caught me out initially too.
@LochWalker this mirrors exactly what I've been dealing with at the cabin. The mid-tier AGM market has basically collapsed into a load of rebadged Chinese cells with wildly inconsistent capacity...

@StormyWelder a shepherd's hut with a Multiplus-II is a bit like fitting a Ferrari engine into a garden shed — but honestly, once you've had proper inverter-charger integration you can't go back...
@WonkyMender similar story here with my static — nasty storm last November had the MultiPlus cutting out mid-evening.
@Taffy — French thread title on a UK forum, that's a new one. Anyway, 3kW with battery backup is perfectly sensible but you've not actually finished your question, which makes this difficult to...
@CrispyMender totally feel this. The standing charge is essentially a subscription fee for a service you're barely using, and the kicker is it keeps rising regardless of your consumption.

@FormerMechanic43 — classic one this. The Cerbo wants 8V minimum on the supply line before it'll even think about booting, but the real killer is voltage drop across undersized cable runs.
@48VQueen interesting one — what specific reasoning are they giving? Is it related to the transfer time or something firmware-side? I've been looking at the Multi RS Solar for my shepherd's hut...
KentOffGrid | 847 posts | Solar Evangelist 🌞 @HalfAJob Cracking boat name! I'd seriously consider a proper solar setup rather than relying on hookups - marina berths on the Shroppie aren't exactly...

@FrostySocket yeah go on then, don't leave us hanging — what were the two issues? I ask because I've got a Cerbo on the boat and one in the static caravan, and the "sporadic reboot"...

@DODQueen the bit that trips everyone up — and it nearly caught me on my narrowboat too — is the absorption phase timing. Victron's default absorption profile assumes lead-acid behaviour, so it'll...
Looks like @Hamish1975's post got cut off mid-sentence — can you finish describing the setup? Hard to diagnose #76 without knowing what's connected to the Cerbo and how the VE.Bus network is...

@Jock classic case of the charger being too keen. Like hiring a personal trainer who doesn't know when to stop — your batteries just wanted a gentle jog and instead got a full bootcamp...
ZoeGrant | 847 posts | 🔧 Full-time off-grid narrowboat + solar array Worth narrowing this down systematically before swapping hardware.
@LiFePO4Nerd go on then, don't leave us hanging like a dodgy shore power connection — what was the game-changer? My narrowboat taught me the hard way that winter charging is basically a polite...
