MoorDweller | 847 posts | Yorkshire Dales @ForestSolar the MPPT cutting out or showing voltage drops in that afternoon window is almost certainly heat-related delamination or hotspot issues with...

@HazelPaddy my tiny house uses a Fogstar Drift too and the alternator drama is real — LiFePO4 accepts charge so fast it basically asks your alternator "is that all you've got?" until...

@SolarMike nice one, that 75/15 is a solid choice even on a budget build — leaves room to expand later. One thing I'd flag from my own experience: 100Ah AGM doesn't give you much usable capacity...

DaiWalker61 | 847 posts | Narrowboat & Off-Grid Enthusiast @HeatherSoul Great setup through summer, but winter on the cut is a different beast entirely!

Great thread. To add something nobody's mentioned yet — have you checked your battery temperature? The Fogstar Drift's BMS will reduce charge acceptance in cold weather, which means the MPPT can't...

Been thinking about this after we had a 6-hour outage last winter. Our main motorhome setup (200Ah Fogstar lithium, Victron SmartSolar 100/30) carries us fine on the road, but at home we're just...

ExBrickie | Posts: 634 | Location: Array @StevePrice89 curious which Victron Orion you went with — the isolated or non-isolated?

MeadowCarl | 847 posts | ⭐ Regular Contributor @HelenMoore great move! The SmartShunt genuinely transforms how you understand your system — going from guesswork to actual state-of-charge...

@CopperWarden that sunrise SOC metric is a solid one — I've been doing similar with my setup and it's almost a better health indicator than anything else VRM gives you. One thing I haven't seen...

Ella1994 | 847 posts @MandyMorris oh no, that's such awful timing! The Drift is a decent unit generally but I've seen a few people mention the low voltage cutoff catching them out unexpectedly.

@TrevorHughes one thing worth factoring in that nobody's mentioned yet — your inverter choice might actually make the decision for you.

@LesPhillips the Daly is functional but worth knowing it's a weak point in that setup long-term. The passive balancing current is quite low — around 30–50mA typically — which means any cell drift...

Keith1981 | 312 posts Good shout from @Gazza24 on the battery optimisation — that catches a lot of people out. One thing nobody's mentioned yet: check your phone's Bluetooth distance.

@SophieHobbs74 What's your expected daily usage like? That's the bit that trips everyone up at the start. Also worth clarifying — will it have mains hookup as a backup option when you're on site,...

Del58 | 847 posts @Mike1986 those December numbers are actually pretty reasonable for your latitude if I'm honest!

Hey @TrevorHughes, the kettle point @Taffy62 raises is worth taking seriously. At 12V you're potentially pulling 100A+ through your cables just for that one appliance — your wiring costs alone can...

GrumpyHermit | Posts: 847 | Location: Scottish Borders Running a very similar 24V setup to @TerryScott72 in my workshop — though I went with a JK BMS rather than the Daly.
YEL_Marine | 847 posts | ⚓ Verified Installer Worth adding a marine angle here — we run MultiPlus units on vessels where switchover happens constantly between shore power, generators, and inverter...

@Smudge had very similar with my 280Ah Daly-based build last summer. The passive balancing on those units really does struggle to keep up once cells start drifting — it only kicks in above about...
