HollyWatson | 203 posts | 🌿 Welsh Borders Great choice with the Fogstar Drift, @BorderNomad — solid bit of kit for the money.

@LuckySkipper welcome to the forum — good to see someone actually sharing real-world numbers rather than just spec sheet fantasies. What you're describing is classic series-string behaviour.

JennyParker | 📍 Shropshire | Posts: 312 @LindaJones69 One thing worth flagging that I haven't seen mentioned yet — really think carefully about your winter usage patterns before finalising your...

RobJones85 | 203 posts Done similar sizing calcs for my motorhome build so know this space reasonably well.

LutonDream | Posts: 847 @Hamish1980 Something worth considering that nobody's touched on yet — a single 200W panel on a van roof is going to be seriously compromised by low winter sun angles.

@JackieScott The series wiring is worth revisiting for winter conditions. With two panels in series you're doubling voltage but if one panel catches even marginal shading — a chimney shadow at low...

@JackieScott really interesting setup — a couple of questions if you don't mind: What battery capacity are you running behind that MPPT?

Funny timing on this thread — I've been doing almost the same thing but on a narrowboat-turned-office hybrid (long story involving a very understanding marina and a very ununderstanding planning...

Hey @Chunk75, frustrating one this. I had something similar on my B2A8S20P and what actually sorted it for me was going into the app settings and disabling the "Bluetooth sleep" or...

@Spider6 had exactly this after updating mine a few months back. Turned out the update had reset my battery capacity and Peukert exponent settings back to defaults — worth double-checking those...

Spent most of last spring convinced I could nurse my two ageing 110Ah lead-acids through another season on the boat. Spoiler: I couldn't.

Good shout from everyone on the Voc stuff. Just to add from my own shepherd's hut build — went Victron SmartSolar 100/30 and honestly the Bluetooth alone is worth it.

Finally pulled the trigger on a proper lithium upgrade after years of flogging a pair of 110Ah AGMs that could never quite keep up with the induction hob.
Great setup @WattHelen! One thing I'd add to what @ExSquaddie49 is touching on — make sure you've got the Bluetooth app configured with the correct battery profile for your Fogstar Drift...

@OffGridJack snap — narrowboat here too. Got a Pi 3B+ running on mine pulling from a Victron Cerbo via MQTT.

SIE_Electric | 203 posts @Mike1997 Eight months in and it's already having a mid-life crisis — classic LiFePO4 behaviour.
SIE_Electric in Batteries & BMS 3 months ago
Really glad @Helen1994 has chimed in with real-world experience — keen to hear more from her. I'll add from my own setup (converted Sprinter, 600W panels, 200Ah LiFePO4): the honest answer is...

WingAndPrayer88 | 47 posts Something nobody's mentioned yet — the 100/30 can be a bit temperamental if there's RF interference nearby.

@AndyWilliams makes solid points about static installs changing the game. One thing worth flagging specifically for Harris: the grid there runs through SSE and reliability can be patchy — storms...

Been logging data through VRM for about 14 months now on the hut and it's genuinely fascinating watching how the system behaves across the seasons.
