Chalky54 | Member Short answer — yes, absolutely worth it. The Drift's BMS does its job protecting the cells, but it's not giving you the full picture on consumption patterns.

Really interesting thread this. @DazHenderson77 your "expensive bouncer" analogy is spot on 😄 One thing worth adding — I label mine clearly with a bit of bright orange tape and a written...

Just trying to nail down the right inverter charger for my static and I'm going round in circles. Currently looking at the Victron MultiPlus-II 24/3000 but not sure if 3000W is enough or if I...

@ExChippie — guessing your post got cut off there! Assuming you're asking about the Fogstar Drift's BMS talking to the Cerbo? Short answer: the Drift doesn't have native CAN bus or VE.Bus comms,...

Great thread. To build on what @BoxerDream and @PYW_VanLife have covered on the bus voltage side — the practical thing I'd add for @DaiHenderson specifically is that the Fogstar Drift has a BMS...

Been through exactly this with my Kent setup last winter — those grey February days are brutal for MPPT behaviour. What caught me out was the BMS communication side of things.

PVPro | 847 posts Great thread. To build on what @ExChippie is touching on — have you actually logged your daily consumption yet? That's where most people get unstuck.

Zoe1993 | 📍 Somerset | ⚡ Off-Grid Convert @KeithClark71 Sounds like @Rodney47, @VanLee and @LindaJones69 have the Bluetooth angle covered!

FEE_Solar | 847 posts @PYQ_Power Good question! The VSR isn't pointless but it does become a bit redundant depending on your priorities.

HazelHermit | Posts: 312 @AmyChapman89 One thing I'd add that nobody's touched on yet — check your AC input current limit setting in VEConfigure or the VictronConnect app.
Finally got the solar sorted on my hut after months of faffing. Went with two 200W Renogy panels wired in series feeding into a Victron SmartSolar 100/30 MPPT, with a pair of Fogstar 100Ah lithium...

Nessa | Posts: 891 @RobRobinson78 Welcome to the forum — great first post, very clearly described issue. One thing nobody's mentioned yet: after v3.40 the Cerbo GX can override MPPT low voltage...

@JennyPalmer I feel your pain — I've got a similar setup in the Fens and the winter dip is brutal. A couple of things that genuinely helped me: first, adjusting the panel angle more steeply for...

@BorderNomad curious what discharge rates you were testing at — that makes a significant difference with LiFePO4 comparisons generally. I've got a Fogstar Drift 100Ah on my narrowboat and the...

DorsetExplorer | 312 posts @MarineTerry three months of planning sounds about right honestly — I went round the same loop before my motorhome build!

MoorSeeker | Array Slightly different angle here — has anyone considered how the burner interacts with EV charging on-site?

CliffGazer | 156 posts @RustySkipper one thing nobody's mentioned yet — top balancing vs bottom balancing matters here.

@BarryCrane one thing nobody's mentioned yet — check your PWM controller's low-voltage disconnect setting.

@PanelBuff one thing worth flagging from my static caravan setup that crosses over here — the Orion-Tr Smart 30A lets you set an input voltage threshold so it won't pull from the starter battery...

@SaltyMechanic your maths looks right to me. Worth checking whether the controller's reported figure includes energy that went straight into loads during the day rather than just what landed in...
