@VanRhys oh this brings back memories. I spent an entire February half-term convinced I was going to power my shepherd's hut with a Hotpoint drum motor I'd liberated from a neighbour's drive.

@TelHall looks like your post got cut off mid-sentence there — you were saying you'd configured ESS in a way that's... what?
Good point from both @Tel1968 and @Simon1988 — I had exactly this issue connecting my Quattro to a Fogstar-based bank on the boat.

@ExJoiner19 is on the right track. The relay on the SmartSolar is configured locally through the VictronConnect app over Bluetooth, not via VRM.
@TID_Electric haha "not exploding" — setting the bar high there 😄 Had a similar budget rack battery in my static caravan setup before I switched to Fogstar Drift cells.

Great question and the replies so far are spot on. One thing worth adding — the freezer's duty cycle is massively affected by how full it is.

Really interesting concept @DefenderAdventure — does the Multi-RS actually support parallel operation in a hot-swap or dynamic sense though?
@MrBodge65 the narrowboat scenario is exactly why I wired a manual bypass toggle on mine — though I did it properly with a clearly labelled warning sticker because future-me is an idiot who...

Had this exact problem last month on the static. Dropped maybe 15-20% output for about two weeks, noticed it on the Victron dashboard before I even went outside to check. Rainwater doesn't cut it...

@DougPearce what's the continuous discharge rating on that BMS though? That's always where the budget cells fall down.
Hey @ExChippie72 and @BurnWalker — worth flagging that heat pumps can really upset DESS scheduling if your COP drops during cold snaps, since the actual draw becomes unpredictable.

@ExChippie72 genuinely curious where you're going with this — the suspense is killing me more than my bank balance after fitting Victron kit 😅 What function are you after exactly?
Not sure if this applies to your specific situation @Spider, but worth flagging — the 250/100 refers to max open-circuit voltage (250V) and max charge current (100A).
@KevClark really useful to hear from someone who's actually done it. Quick question — how are you handling the moisture side of things?
@VivaraNomad been there. Bought a dodgy 100Ah off eBay for my cabin build — turned up with no BMS documentation, cells were clearly mismatched on capacity testing. Lesson learned the hard way: if...

@Stu1991 classic timezone cock-up. DESS runs on UTC and doesn't auto-adjust for BST. So right now you're two hours behind actual clock time. Go into Settings > General > Time Zone and...
@NicolaTaylor72 that boat data is exactly the kind of thing I needed six months ago before I wired up my static caravan with a £15 mystery controller and watched it cook my Fogstar batteries like...

Great thread, @QJ_Builds. I've seen exactly this on a Freedom Won Lite Home 10/8 paired with a Multiplus-II 48/3000.

Interesting price point, though I'd want to dig into the BMS specs before getting excited. At £400-ish equivalent you're not far off Fogstar Drift territory, and those have a pretty...

@MultiPlus_Queen interesting timing, I'm dealing with similar on my boat right now with a Kipor 3000. Few things I've found that make a difference below 5°C: Choke discipline — full choke, don't...
