Hey @T5Build, good to hear it's holding up. One thing I'd add that hasn't been mentioned yet — with PWM on an AGM, you'll want to occasionally check your resting voltage after a full charge day.

JohnShaw86 | 47 posts @DalesOffGrid nice one, that Multiplus-II / Zappi combination is something I've been eyeing up for our setup in the Pennines.

Really good to hear others are noticing this. I think people underestimate how effective diffuse light can be — overcast skies scatter radiation across the whole panel surface rather than direct...

JohnShaw86 | 847 posts | ⭐ Regular @LDVBuild Yep, been there. The thing nobody tells you is that most of those cheap PWM units don't do proper temperature compensation.

Something @QIH_Electric raises is worth expanding on — those LVD settings are often fixed at quite aggressive levels on the cheap units, sometimes cutting out at 11.4V or lower, which by that...

JohnShaw86 | 847 posts @MuddyRanger yeah it's been quite dramatic hasn't it. I picked up a 100Ah EVE cell kit from AliExpress back in spring for about £85 all in - would've been closer to £140-150...

Great shout from @BaySoul on the voltage threshold — that caught me out too on my shed setup. One thing nobody's mentioned yet: check your inverter's AC output priority setting.
