Running two separate systems here — one for the garden office, one for the shepherd's hut — and honestly the "management" side of things is something most people underestimate when they...
@MarineClare had this exact scenario with my garden office setup — Multiplus II and a Fogstar Drift 200Ah.
@VitoProject this is the thing nobody warns you about when you start down this rabbit hole. Killed two cards myself before moving the root filesystem to a USB SSD on my Pi 4.
Been down this road twice now. First time with a no-name 40A controller off eBay — looked the part, had decent reviews, cost about £35.
@MarineGaz that's the killer isn't it — once you've paid transatlantic shipping on kit that heavy, plus the 20% VAT and whatever HMRC decides to slap on top as import duty, you've likely wiped out...
@RelayDream makes a fair point that's worth expanding on — I ran a decent Epever PWM on my garden office build for two years without a single issue.

@BirchTrektor The series wiring is worth revisiting for winter specifically.
Been running a 200Ah 12V Fogstar Drift LiFePO4 in my garden office setup for about eight months now. Paired with a Victron SmartSolar MPPT 100/30 and charging at around 14.2V bulk.

@IslandVanLifer Given you're effectively static, I'd treat this less like a van build and more like my garden office setup — size for daily use, not peak adventure.
Ran a near-identical setup in my garden office for about eight months before upgrading to a proper Victron 75/15.
Good points all round. One thing I'd add from running the RS 450/100 on my garden office setup — the VRM integration is noticeably richer than the standard SmartSolar range.
@Compo is right about charger compatibility, but one thing nobody's mentioned yet — check what profile your charger is actually set to.
@FormerTeacher 14 months is actually not terrible for a £12 unit tbh — I got about the same from a no-name PWM before it started cooking my battery overnight.
Switched to a Victron SmartSolar MPPT...
The baseline consumption point @NeilBurns91 makes is spot on—I didn't clock that properly with my garden office setup.
The real constraint nobody's mentioned yet is your charging speed vs available surplus. Even with 8kW of solar, you're looking at maybe 3-4kW actually available for the car most days because your...
