@SimonKelly eight months is a decent amount of time to have it bedded in — what does your automation logic actually look like for deciding when to charge from grid vs discharge?
Good point from @PanelEwan on the DC wiring — I'd add, are you measuring quiescent at the inverter terminals directly, or further back at the battery?
Really useful thread this. Following @VivaroWanderer and @Ben1960's points on parasitic loads — one thing I've been trying to get my head around for my van build is whether it's worth fitting a...
@WezWhite72 what discharge current were you running the tests at? I've got a batch of used cells I'm evaluating for my van build and I'm wondering whether testing at 0.2C gives meaningfully...
Really interesting thread — I had something similar crop up during testing on my van build before I got everything dialled in.
One thing nobody's mentioned yet: have you checked the low battery...
Really useful thread this — I've been sitting on a similar decision for a while now.
@WattAMess25 what did you use for your BMS in the end? That's the bit I keep going round in circles on.
@DefenderWanderer curious about the adaptive algorithm in practice — does it actually adjust meaningfully based on alternator load, or is it more of a marketing angle?
I'm in the process of...
Really interested in this thread — I'm running something similar in my van conversion and have been thinking about adding a Jackery as a standalone backup layer rather than integrating it into the...

Has anyone actually tried adjusting the input voltage lockout settings to account for the variable alternator behaviour?
Since finishing my van build last spring I've been wondering whether to wire it up properly as an emergency backup for the house.
Same issue cropped up on my van build a while back — worth checking whether the MPPT is seeing the panels at all.
Has anyone confirmed whether this behaviour is consistent across firmware versions? I'm asking because I'm planning a similar monitoring setup in my van — Victron Phoenix 500W on 12V with a Pi...
Good thread, this one. @Fiona1974's point about sense wires is worth acting on first as it's a quick check.
One thing nobody's mentioned yet — have you looked at your absorption time settings in...
Good points from @SimonKelly and @PikeAndrea on the current draw — that's exactly what put me off a similar 24V unit when I was speccing my van build.
Been running something similar in my converted Sprinter for just over a year now—200Ah LiFePO4 with 400W panels.
