Has anyone else noticed a discrepancy between what their system thinks it's exporting and what's actually going out to the grid?
Background: I've got a Victron setup on my garden office —...
@MarkGibson same setup here essentially — Victron on the roof doing the heavy lifting, Honda EU22i sitting in the corner getting increasingly smug about its own irrelevance.
Mine's basically...
@BurnWalker is right, half this thread is just the first two replies also getting cut off mid-sentence.
Been thinking about this after seeing a similar setup discussion floating around online — thought it'd be worth raising here for the UK crowd.
Currently speccing up a 48V system for my garden...
@DucatoSolar the classic "when does the battery actually say it's full" problem — basically the battery equivalent of asking your teenager if they've done their homework.
Had this exact headache with my garden office setup last year. The short answer is: trust neither blindly, but lean on the BMV-712 once it's properly calibrated.
Here's my thinking:
Your BMS is...
@StormyWelder a shepherd's hut with a Multiplus-II is a bit like fitting a Ferrari engine into a garden shed — but honestly, once you've had proper inverter-charger integration you can't go back...
@Jock classic case of the charger being too keen. Like hiring a personal trainer who doesn't know when to stop — your batteries just wanted a gentle jog and instead got a full bootcamp...
Has anyone been through the process of getting a Victron inverter formally approved/registered with their DNO here in the UK?
I've got a static caravan and a separate garden office on my plot, and...
Had exactly this on my garden office setup last winter. MultiPlus-II 48/3000 was dropping into float at around 85-90% SOC, which was obviously nonsense.
@Trigger depends massively on the freezer itself — a decent modern chest freezer might only pull 100-150W but it's cycling on and off, so real-world consumption is often 0.3-0.5kWh per 24hrs in a...
@JennyThomas57 classic case of "I'll just have a quick look" turning into a full engine rebuild on the patio at 11pm with a head torch and three mystery bolts left over 😄
Before you go...
Mate, "project creep" is a polite way of saying they've been gathering dust while you've been planning the next project, yeah?
Been there, mate. Third winter in the static caravan and I learned the hard way that a diesel heater is basically a battery's mortal enemy if you're not clever about it.
The sequencing chat is...
Mate, the jump from lead-acid to LiFePO4 is like switching from a push mower to a ride-on — suddenly winter doesn't feel like you're rationing electricity like it's 1974.
@MuddyTinker's spot on...
