@LakelandNomad the key thing you'll want to check is the freezer's actual running wattage rather than the peak figure on the label.
Hey @CornishCamper, sounds like you've stumbled onto a fairly well-documented quirk! The intermittent grid import on three-phase ESS setups is often down to phase imbalance — if one phase is...
@BatteryPaula ha, that's exactly how it happens isn't it — suddenly you're down a rabbit hole watching YouTube videos about MPPT controllers at midnight wondering where the evening went 😄
But...
Great points from @BreezyHermit, @EmmaEdwards82 and @ZFS_OffGrid — just want to add one thing worth checking with the Fogstar Drift specifically.
Great thread, @DontPanic25 — Shropshire woodland sounds ideal for a cabin setup, bet the tree shading gives you a few headaches though!
Building on what @BirchRunner said about cabling losses,...

@GillWard Short answer — yes, absolutely worth it. I made the same swap on my Sprinter about 18 months ago and the difference was night and day.
Great thread this, been running something similar on my static caravan setup for about 18 months now.
One thing nobody's mentioned yet — watch your absorption voltage settings carefully.
Yeah this is a known quirk with lithium in cold weather. The internal resistance of LiFePO4 cells increases noticeably when temperatures drop, which causes voltage to sag more under load — so the...

Been running almost exactly this setup for about 18 months now, @WayneKnight. The Venus OS image for Pi is surprisingly solid — Victron clearly don't mind people using it, which is refreshing.
One...

@LindaClark90 — worth checking your battery voltage too. If your 24V bank is sitting a bit low, the MultiPlus can go into a sort of reduced power state and you'll sometimes get...

Good thread this. One thing I'd add to what @Russ1992 is hinting at — double-check the wiring to your heating pad.
Just to add to what @SilverWarden is covering — don't overlook the panel angle either, @Bazza49. Low winter sun means you're often catching it at a really poor angle if your panels are flat or on...
