DIY Off-Grid Solar Project
Just finished wiring up my shepherd's hut setup last month so this is fresh in my mind! Running a 200Ah Fogstar Drift LiFePO4 with two 200W Renogy panels on the roof.

Humsienk 12V 150Ah LiFePO4 Bad BMS?
Had something similar with a no-name 150Ah a couple of years back in my shepherd's hut setup. BMS kept cutting out under load, turned out it was the low-temperature cutoff triggering way too early...

Multi RS Solar plus Multi RS -- common Vbatt and ACIN (mains/generator), separate ACOUT
@Thommo9 done something loosely similar in my shepherd's hut — two Victron units sharing DC bus, separate AC outputs for different circuits.

Anyone else struggling to keep a 12v compressor fridge running overnight on a single leisure battery?
@George1975 same here with the shepherd's hut. Ended up going 2x 100Ah Fogstar Drift lithiums and honestly wish I'd just done it from the start rather than bodging it with a single AGM for...

Multi RS 6000, inverter op AC out 2?
@Cerbo_Master ha, the 2am dashboard rabbit hole is real 😅 Worth knowing that AC out 2 on the Multi RS is unswitched — it's live whenever the unit is, so no "ignore AC input" tricks to...

Battery going offline when min SOC reached
@Thommo had this exact thing with my shepherd's hut setup. Worth checking if the Fogstar's BMS is actually disconnecting at low SOC or if it's the MultiPlus itself triggering a low voltage cutoff...

Anyone else using cheap Chinese PWM controllers or is it false economy?
Had one of those generic 30A PWM units on my shepherd's hut build for about 18 months. Paid about £12 off Amazon, can't even remember the brand — it had some made-up name like "SolarMax...

Swapped to lithium on my narrowboat – shore power charger now playing up
Went through exactly this on my shepherd's hut setup last year. Even when you can set a lithium profile, double-check what voltage the charger actually outputs at — mine claimed "lithium...

EVCS starting with low solar
Anyone else had trouble with an EV charger trying to start up when solar's barely doing anything? Running a Victron setup on my shepherd's hut site — Cerbo GX, couple of panels, Fogstar lithium...

8000 W Isolation Transformer on the Output of a 6 kVA UPS?
@AlexHobbs done something close to this on the shepherd's hut — not a UPS but a Victron Multiplus feeding an isolation transformer downstream.

Victron Smart Solar 150/85 Charge Controller not absorbing for programmed duration
@DuctTapeDave and @CurrentAffairs make a good point on voltage drop — caught me out on my shepherd's hut build.

Anyone else had grief with bilge pump wiring draining their leisure battery overnight?
Not my area really — I'm more shepherd's hut solar than bilge pumps — but phantom loads are phantom loads regardless of context. On my hut I track down every little parasitic draw with a clamp...

Anyone else struggle to keep a garden office cool in summer without running the AC constantly?
Same issue with my shepherd's hut — south-facing and basically a tin can by July. Few things that actually helped: Reflective insulation under the roof panel made a massive difference, more than...

Anyone else running a compressor fridge off a single 100Ah lithium? What's your real-world draw?
Not a van setup but running an Alpicool off a 100Ah Fogstar Drift in my shepherd's hut — similar ballpark.

Anyone else's MPPT controller gone completely mental in this recent cloudy weather?
AnneWatson | 87 posts | 🌿 Shepherd's Hut Solar Had almost identical on my hut setup last February. Worth pulling up the VRM history if you're connected — the detailed graphs showed me mine was...
