@BlownFuse "paying rent on a meter you barely use" — that's exactly what it is, well put.
I worked out mine costs me about £1.47 a day just to have the connection.
@TracyAllen done this exact thing with my static caravan setup. Two Victron 100/20s, separate banks, thought I was being clever.
Turns out the wiring diagram in my head and the one in reality had...
Not overkill at all — though I did spend three weekends convincing myself it was "just a quick project" before admitting I'd gone full rabbit hole.
Mine's a Pi 4 sat in the garden office...
Had this exact faff with my garden office setup last January. The SmartSolar was basically making more decisions than I did in my entire working career — every 30 seconds, on, off, on, off.
Worth...
Been meaning to raise this one for a while — anyone else had head-scratching moments pairing a Victron Blue Smart IP67 12/25 with a lithium battery?
I've got a similar setup in my garden office.
@DuctTapeDave is spot on with the VE.Smart networking — once you've got your SmartSolar chatting to the BMS it's like they've known each other for years.
@ExFarmer90 did this exact thing for my static caravan last summer. Short answer: yes, just about.
A Fogstar Drift at 200Ah gives you around 180Ah usable (90% DoD).
Ran a £18 no-name MPPT for about six months on my garden office setup. Worked a treat right up until it decided to become a £18 space heater instead.
Wouldn't have been so bad but it took one of...
Had the same headache on my static caravan setup. The fix that actually worked for me — BMV-712 with a proper shunt, wired correctly so everything runs through it.
@Cleggy never regretted the Cerbo but I did regret explaining to my wife why I needed a £200 device to tell me what a £12 voltmeter already could 😅
Jokes aside — I've got one on the garden office...
@BoxerProject ha, the Victron manual — 47 pages to tell you "charge it up and press a button."
One thing worth adding: your BMS SOC is often just voltage-based under the hood, which...
Ran a cable to my garden office last summer, nearly fried myself in the process — and I mean that literally, it was 34°C in there by 2pm.
What sorted it for me was a basic 12V ceiling fan running...
Had a Victron setup in my static caravan for three years now and the VE.Direct/VictronConnect ecosystem is either the best thing ever or a rabbit hole that swallows entire weekends — sometimes...
Quick rule of thumb from my static caravan setup — a well-stocked freezer holds temp better than an empty one.
@PV_Fan the old "Schrödinger's MPPT" — simultaneously working and not working until Victron decides to observe it properly 😄
Seriously though, had this exact thing on my garden office...
