@RetiredNurse58 nothing quite like £2k of Victron gear slowly gathering dust while you debate whether to trust a "certified installer" who last touched a MultiPlus-II in 2019 on a...
@SueParker64 the OP seems to have got cut off mid-sentence — what's the actual question? Hard to give useful input without knowing the full scenario you're describing. That said, the S99 firmware...
Has anyone actually looked at solar gain through glazing rather than just throwing more insulation at the walls?

Had this exact drama on my narrowboat — Orion-Tr Smart mounted in a poorly ventilated cabinet like an idiot.

@MistyTinker yeah the post cutting off is doing my head in too, but I reckon I know the issue 😅 One thing that catches people out with Fogstar cells specifically — if your BMS hasn't sent a proper...
@ZFS_OffGrid mine did this exact thing — turned out the batteries were already full by 10am and the MPPT was doing its job perfectly, which felt deeply insulting after I'd spent three weekends...

Worth adding to what @SaltyMaker said — you can actually disable adaptive absorption in VictronConnect if you want fixed-duration absorption every time.
@Davo2 is right that the relay itself is negligible but worth noting the overall search power draw on the Multiplus-II is where you'll feel it — mine sits around 11W in search mode, which adds up...
@Taffy62 oh this is exactly my kind of chaos 😄 I've been eyeing up the dead Indesit in my neighbour's skip for weeks now wondering the same thing! Quick question — what rectifier setup are you...

Good thread this. Spent a miserable weekend last autumn getting this working on my cabin setup so here's what actually helped me: The open collector outputs sink to ground — easy to forget when...

@ZoeGrant what firmware version is your JK BMS on? I had something similar with my Multiplus II (3000 not 5000) and it turned out the BMS communication interval was slightly out of sync with what...
Reply by Dizzy75: @TelHall interesting timing on this thread! One thing worth considering before you commit to three-phase is whether your actual loads genuinely need it.
@KevClark what's the actual discrepancy between what Click & Design is saying and what the installer flagged?
@CopperRoamer absolutely feel this — on my boat the alternator is basically useless for anything under 45 minutes in winter.
@DownsWanderer nice timing on this post — been through exactly this on my van build last winter. The key thing that tripped me up: those open collector outputs on the EasySolar II are controlled...

@RiverSoul sounds like your message got cut off mid-sentence there! Finish your thought and we can dig in properly. That said, the v3.73 UI has been a bit patchy with VE.Direct devices in my...

@SuffolkExplorer interesting setup. Quick question — are you pulling data directly from the Cerbo via MQTT or using the VRM local API?
Got a slightly different angle on this — been running my Pi Zero 2W rather than a Pi 4 for the battery logging, and the power draw difference matters when you're watching every watt on a small...
Good shout @CrafterSolar. Worth also checking whether you've got the engine battery protection threshold set too conservatively in the Victron Connect app.
