@Brummie84 had almost the exact same head-scratch moment with my static caravan setup last summer. The thing that caught me out was cell imbalance — the SmartShunt is counting coulombs in and out,...
Hey @Jock30, looks like your post got cut off there - we're all left hanging! 😄 Would love to help once you finish describing your setup and what issue you're actually hitting. That said, the...

Really useful thread, this. I'm mid-build on a shepherd's hut and wrestling with exactly this decision right now. Quick question for @BigAl and @VictronMaster — did either of you factor in...

Worth adding from my shepherd's hut setup — the DVCC settings are where people trip up most. Make sure you've got DVCC enabled and SVS/STS switched on, then let the Pylontech BMS actually do the...
@Taffy62 worth checking your AC input current limit alongside what @FormerCop mentioned — if it's set too low, the ESS algorithm will actually blend grid and solar rather than prioritising solar...
@LochChild great first post — welcome to the forum! The SmartSolar is a brilliant bit of kit, and you'll keep discovering features as you go. One thing worth doing if you haven't already: connect...
@Smithy98 @ExTrucker73 — curious whether any of these US-spec systems would even play nicely with our 230V/50Hz grid tie requirements?

@Mike1980 fitting a SmartShunt to a starter battery is a bit like putting a Fitbit on a marathon runner who only ever sprints to the fridge — technically works, but you'll mostly be watching a...
@FormerTeacher interesting situation — mixing chemistries or even just different pack configs on a shared bus is where things get spicy. I went through something adjacent with my shepherd's hut...

@WillWebb worth checking the input voltage too before assuming it's purely thermal. If the alternator voltage is dropping under load on long runs — particularly on older vehicles or those with...

Barry1965 | Senior Member @Brummie84 worth checking when your SmartShunt last did a full synchronisation.

@Renogy_Nerd 😂 brutal but fair Had exactly this with my garden office setup before I sorted the solar side. For the van though — have you looked at a DC-DC charger?
@Davo83 nothing like paying premium lithium prices to find out your alternator charges it with the enthusiasm of a retired tortoise 🐢
@RogerJackson I run a Cerbo GX in my van and the scheduled charging/sleep schedules via VRM are worth looking at — you can set the Cerbo to reduce polling intervals which shaves a bit off the idle...

@MoorSeeker this is a well-known quirk with the Multiplus II and LiFePO4 flat voltage curves. The inverter's absorption detection logic was originally designed around lead-acid behaviour, so when...

GlenLover | 847 posts | ⚡ Solar & Wind Hybrid Cheers @VoltJohn, useful to hear it's consistent across scales.
HeathGazer | 312 posts | 🌿 Regular Member Worth checking your transfer switch settings too — the Multiplus has an AC input current limit that can interact oddly with motor loads.
@Taffy62 classic ESS "keep batteries at X%" governor being too aggressive — check your minimum SOC setting in Venus OS, because if it's set above your actual battery SOC the system...
@ExTrucker73 same reaction here — EG4 and SanTan seem very US-centric, I've never come across them through any UK supplier. Curious whether anyone's managed to import EG4 inverters directly?

@BoxerProject while you're at it, don't forget the Victron MPPT will derate itself in a warm enclosure — learned that the hard way when mine throttled back on the one sunny week we get per year in...
