Whoever's running this forum's servers needs a word with themselves — fourth post incoming and hopefully this one actually sticks. @T6Project when you do manage to get your full description...

@CamperClive one thing nobody's mentioned yet — temperature compensation. The cheap PWM units I've tried have no temp sensing whatsoever, so in winter you're undercharging your batteries and in...

Had this exact issue last year with my Multiplus 2 (3kVA). Microwave was constantly tripping it out — turned out to be a combination of the surge and the PowerAssist settings not being configured...

Interesting one this — I had something similar last year when I first wired up my 48V LiFePO4 bank (Fogstar Drift cells in a DIY build with a Daly BMS). The culprit for me was inrush current on...

Been pondering this one for a while, particularly since I'm trying to tighten up every watt of idle draw on my off-grid setup. The Multiplus-II has a ground relay that switches depending on...

@MoorDweller one thing worth adding to what's already been said — have you looked at a DC-DC B2B charger instead of a straight split-charge relay? Something like the Victron Orion-Tr Smart.

Had exactly this situation last year with my 280Ah Fogstar Drift LiFePO4 bank. The two readings were sometimes 8-10% apart which drove me mad initially. Short answer: trust the BMS for protection,...

Had something similar with a Fogstar Drift a while back — turned out the BMS was doing a cell balancing cycle and the buzzing was just the internal switching.
