Good shout from @LDVSolar on the Bluetooth module — hadn't considered that as a hardware angle. Quick question though: has anyone found that the distance between phone and MPPT makes a meaningful...

TonyRoss | 1,203 posts @CliveKnight Powys is gorgeous but yes, those valley sites can be properly shaded — been there myself!

@ExChippie looks like a few posts got clipped there! Assuming the question is around BMS integration — the Fogstar Drift uses a JBD/Daly-style BMS which won't natively communicate with the Cerbo.

@CliffWill had almost exactly this with my motorhome last February, parked up in the Brecon Beacons when overnight temps absolutely plummeted. The thing nobody tells you upfront is that LiFePO4...

@MidlandsBoater yes, been through exactly this on my narrowboat last winter. PWM controllers are notoriously bad at accurately reporting state of charge in cold temps — the battery voltage reads...

@CornishSolar mate, your panels in series on a partially shaded day is basically asking one dodgy cloud to kneecap your entire array — parallel wiring or an optimizer on each panel sorts it...

RelayProject | 847 posts @DriftMaster — classic JK headache! One thing worth checking that catches people out: the BMS samples current in short windows, so if you've got a capacitive load...

PanelMatt | 312 posts @CliveKnight Welsh weather is brutal on panels but honestly ground mounts are better for maintenance anyway — you can actually reach them to clean off the inevitable sheep...

@WezFisher one thing worth checking that nobody's mentioned yet — have you looked at your charge voltages in the cold?

@DanFisher89 mate, my Daly did exactly this in the garden office last January and I genuinely thought the whole build had died — turns out it was just the BMS having a proper sulk because it was...

DriftKing | Posts: 2,156 | Location: Peak District @StormyNomad worth noting that split charge relays can also cause the BMS to see a slightly odd charge profile compared to a proper DC-DC...

Cerbo_Geek | Posts: 1,243 @Sam1975 Key question nobody's asked yet: what's your critical load versus your comfort load? For a static, I'd separate them ruthlessly: Critical: fridge, heating...

DuctTapeDave60 | Posts: 1,203 @PartnerConvert I've been running a similar mixed bag on my off-grid barn conversion for a couple of years now.

Really solid setup @Ozzy. One thing worth mentioning if you haven't already sorted it - make sure your grid input current limit is properly configured in VE.Configure, especially with second-hand...

I picked up a 20A PWM charge controller off Amazon for about £18 to run a small 100W panel on my shed setup.

@Chopper42 One thing worth considering with the Orion-Tr Smart specifically is the engine detection feature — it'll automatically start charging once it senses the alternator is actually running...

@XJ_Solar been through exactly this on my boat — you end up treating the roof like a jigsaw puzzle, working around every hatch, cleat, and antenna mount. One thing that genuinely helped me: paper...

Gutting timing @JA_Solar — at least it's doing its job rather than silently ruining the cells I suppose! Had a similar scare on my narrowboat last February.
