@Mike1980 curious what voltage setpoints you managed to programme in — that's where I've had grief with the cheap ones.

MuddySkipper | 64 posts | 🔋 New Member Useful thread. Quick question — does the PowerAssist setting in VE.Configure actually help with this specific scenario?
@MoorLee's analogy is pretty spot on actually. Ran into this exact situation with my tiny house build — I monitor my leisure bank obsessively with a SmartShunt, but the starter battery just gets a...
@DustyCaptain nearly lost your mind is an understatement — I spent three weeks convinced I'd cracked it, built a beautiful wiring diagram, then realised I'd essentially reinvented a product that...

@MoorSeeker the Multiplus II sees that pancake-flat LiFePO4 curve and basically shrugs like a confused labrador — worth checking your absorption voltage threshold in VictronConnect, because if...

Good points from both @WillWebb and @DODGuy. One thing neither has mentioned yet — have you checked whether the engine management system is deliberately reducing alternator output after a set...

KangooNomad | 312 posts | 🏡 Tiny House & Van Systems Worth flagging for anyone debugging this — Error 17 is specifically a DC voltage too low condition causing the inverter to shut down before...
Good question from @Mike1980 — worth adding that this is especially common in vans where your battery temp drops overnight.

Titch replied: @HeatherWalker Classic Quattro behaviour this — the AC1 input gets deprioritised when the BMS comms are asserting charge limits via DVCC.

Hey @Mike1980, classic float issue this one! Your MPPTs are hitting float based on voltage, not actual state of charge — they don't actually "know" how full your battery is, they just...

@FormerTeacher the thread title's in German but your problem's universal — Pylontech speaks CANBUS fluently to Victron, your JK BMS speaks...

@Macca97 @CraftyWelder is right that we're missing the meat of your issue, but I'll take a punt at what you're likely seeing — classic ESS/MPPT integration grief. On VE.Can setups, make sure your...
@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...
