Configure Multiplus II 24/5000/120-50 for Lynx Smart BMS NG 500 and two LFP25,6/200
Good spot @CotswoldNomad and @DailyBuild — definitely worth sorting that out before we dig into specifics, as the charge current limits and assistant configurations will differ between the 3000...

Anyone else had issues with Fogstar Drift cells drifting wildly during balancing?
OakTel | 1,203 posts @Macca97 Yeah, looks like your post got cut off — don't leave us in suspense! 😄 While we wait, I'll say the Fogstar Drift cells generally have a decent reputation but like...

Anyone else had grief with a Victron Multiplus 2 tripping on high loads — 240V cooker problem
OakTel | Posts: 412 | Location: Cumbria @SolarGeorge one thing I haven't seen mentioned yet — have you checked the surge rating vs your cooker's startup draw?

Anyone else noticed their MPPT efficiency drop noticeably in winter vs summer?
Really good point from @T5Project on the Voc ceiling — worth anyone in a similar setup actually doing the cold Voc calculation rather than just assuming you're fine because summer figures looked...

Anyone else running a Victron Orion-Tr Smart in non-isolated mode? Worth it over isolated?
Something worth adding that I don't think anyone's covered yet — the non-isolated Orion-Tr Smart does run slightly cooler and more efficiently in practice, which matters if you're mounting it...

Victron Multiplus-II 48v tripping under EV charge load — anyone else had this?
@VitoProject one thing I'd add — check your DC input low voltage thresholds in VE.Configure. If they're set conservatively (easy to do with LiFePO4 cells), the Multiplus can start throttling...

Anyone else had grief with JK BMS dropping cells below 2.8V before tripping?
Been running a 280Ah LiFePO4 bank (4S, EVE cells) in my van for about eight months now and I keep having an issue where one cell – cell 3 if it matters – dips to around 2.75V before the JK BMS...

Multiplus II mit LiFePO4 NG
Yeah @Brummie84, noticed the same thing when I expanded my own bank recently. Victron's ESS assistant parameters in particular seem to shift between firmware updates without much fanfare in the...
