Had this exact saga in my van conversion last winter — once you've ruled out the obvious (dust, temp, disconnected fan), grab a multimeter and check the fan's supply voltage while the unit's under...
@BMS_Geek the IP22 going into a sulk after shore power drops is basically a Victron rite of passage — check whether the GL520 is sending a false "bulk complete" signal via VE.Direct that...
@MrBodge65 the narrowboat scenario is exactly why I wired a manual bypass toggle on mine — though I did it properly with a clearly labelled warning sticker because future-me is an idiot who...
@RetiredNurse49 "leaving about" is doing a lot of heavy lifting there — my Victron Connect app practically laughed at my old PWM's efficiency numbers when I first compared harvest logs...
@TracyKnight that Voc jump is why you want to double-check your series string doesn't nudge past the MPPT's input ceiling on a cold morning — 100V limit on the 100/30 gets closer than people think...
@T5Project
Running a 30A PWM knockoff in the van conversion for 14 months — paired with a Fogstar 100Ah lithium which, in hindsight, deserves better company, but here we are.
Had this exact saga with mine in the T5 — turned out my phone's battery optimisation was aggressively killing the Bluetooth connection in the background.

Ran into this exact thing last January in my T5 — Voc was spiking well above the "rated" figure on frosty mornings, which looked like the MPPT was lagging behind but was actually just...

EV charging from a 200Ah bank is essentially asking your system to donate a kidney every afternoon — done it in the van conversion and learned quickly that a dedicated EV charging buffer (I run a...

@DevonNomad solid advice — just worth noting that "solar noon" on a UK autumn day basically means "slightly less disappointing cloud" so factor in that your test conditions may...
At £300 you're basically choosing between a paperweight with a fancy screen or something that'll actually run your kettle for five minutes before staging an existential crisis.
Moisture on a narrowboat is basically just a slow-motion short circuit with added philosophical despair.

Shepherd's hut in the Cotswolds sounds ace, but mate—winter sun angle there is brutal for solar. Go battery-first, solar-second, or you'll be running a diesel genny by February like everyone else...
Absolute this—spent three months convinced my van's 200W panels were "plenty" until November arrived like an unwanted relative at Christmas.
Your 6kW nominal is decent on paper, but washing machines are basically tiny power stations having a tantrum for 3 seconds during spin cycle.
