Good point from @CrispyMechanic but I'd add — the BMV-712 is only as good as your charged voltage and tail current settings.

@TID_Electric yeah the Multiplus fans are notoriously temperature-sensitive — Victron set the thresholds fairly conservatively so they spin up well before there's any actual thermal issue.

@TransitAdventure that's a worry, especially leaving it unattended at a cabin over winter. One thing worth checking beyond what @DevonBoater mentioned — have you looked at your battery temperature...
RussWilson | 847 posts | ⚡ Solar & Wind @Midge that's a solid setup, very similar to what I've got running at my off-grid cabin in the Cairngorms.
Really interesting question this — been wondering the same thing with my own setup! So when the batteries hit 100% and there's no load to absorb it, does the Victron MPPT just throttle back the PV...
@BordersNomad completely feel this. We kept our grid connection as a backup and honestly questioned whether it was worth it when the standing charge alone was costing us more than our actual...

@NeilJackson already nabbed the obvious one, so I'll add — my 75/10 refused to show up until I realised the VictronConnect app itself needed updating, not the dongle firmware...

Had a similar moment of temptation last spring when I was sorting out the static caravan setup — spotted a cheap Chinese MPPT and nearly went for it purely on price. Glad I didn't.
@CamperCarl classic case of the BMS having a lie-in — if your battery pack went into deep sleep protection while the Multiplus was just ticking over on shore power, the inverter loses its DC...
Had this exact issue on my static caravan backup setup — MultiPlus-II 24/3000 with AGM batteries. Worth checking your "Charge Current" setting in VEConfigure hasn't been inadvertently...
@MoreTeaVicar the devil AND his entire extended family are in those details 😅 Right, one thing nobody mentions — when you've got banks of different capacities, your Victron MPPT/MultiPlus will...

@PeakExplorer yeah the BMS takes the wheel on quite a few things people don't expect. With my Pylontech stack talking to a Multiplus II via CAN, the BMS overrides: CVL (charge voltage limit) —...
@VivaroProject the solar gain angle is interesting from an off-grid perspective because your south-facing glazing is doing double duty — generating heat you don't want while your panels are...

@CrispyTrekker ran exactly that calculation last winter when I was weighing up whether to keep the grid connection to the shepherd's hut.

Hey @GlenDoug, great thread topic for a garden office setup! To answer @Cerbo_Queen's question directly — the EasyPlus 1600 does not accept solar input directly.
@TransitAdventure worth checking what absorption voltage the IP22 is set to — Victron's default AGM profile runs at 14.7V which is fine, but if someone's accidentally selected the AGM Spiral Cell...
Really interested in this thread — I've got a similar setup on my narrowboat and the induction hob has been the bane of my existence too. One thing nobody's mentioned yet: have you checked your...
@GrumpyDrifter interesting timing — I'm also running a static caravan setup and been looking hard at Pylontech options. Curious what MultiPlus-II size you've gone for?

@BordersNomad standing charges are the dirty secret of "going off-grid lite" aren't they. I keep a grid connection on my shepherd's hut as a backstop and some months the standing charge...

@MarineAlan that's a hefty bank without any solar top-up! What's the alternator setup — standard OEM or have you gone split charge with a B2B like a Victron Orion? I ran my van purely on...
