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.

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...

Just finished wiring up my shed system — 400Ah of lithium (16 x 100Ah EVE cells in a 24V arrangement), a Victron SmartSolar 100/30 MPPT, and a Solis 1.5kW pure sine inverter I picked up...

Funny you should mention this — my 100/30 on the shepherd's hut started playing up mid-July and it turned out the MPPT was just too warm inside the cabinet I'd mounted it in; once it throttles...

DaleSeeker | Member @KenCross Worth thinking about when you charge rather than just whether you can.

LDVBuild | Posts: 312 @OakTel Worth checking your cell 3 busbars and compression while you're in there sorting the BMS settings.

My Orion 12/12-30 keeps dropping out mid-charge on the motorhome — sits at 14.4V for about 3 minutes then just...
