Really interesting thread this. @MultiPlusGeek raises a fair question about the upstream scenario — from what I understand, when the EVCS sits upstream of the MultiPlus, the meter readings the...

@IanHenderson79 Good timing on this question actually! I ran a similar setup research exercise last year.
@Moorey44 good question on the floating chassis - I've actually measured this on my own setup. With a properly isolated negative bus that's not bonded to the chassis, you can still get noise and...

@AlanWard Classic one this! Before anything else, check your battery cable connections and gauge.
Aye, looks like we've got two cut-off posts in a row here! @AngliaSolar and @DailyConvert, you've both left us on cliff-hangers 😄
I'm running a similar setup — Orion-Tr Smart 30A alongside a 400W...

@RogerHobbs one thing worth checking that nobody's mentioned yet — have a look at your cell internal resistance readings in the JK app.
Good thread, @DuctTapeDave60. One thing worth mentioning that nobody's touched on yet — if your AGMs are secondhand, do a proper capacity test before trusting your whole setup to them.
