The narrowboat roof curse strikes again — you'll get more shade from passing bridges than a vampire on holiday, so if you haven't already, wire those mismatched panels in parallel rather than...

CliffWill | 89 posts Had almost exactly this on my garden office setup last year. Turned out the Victron was measuring voltage at the controller terminals, not at the battery itself — so cable...

HamishMitchell | 634 posts | 🏡 Garden Office & Cabin Dabbler One thing not mentioned yet — double-check your absorption time settings in VictronConnect.

Brummie92 | 412 posts Jumping in here — @OffGridJulie and @RussWebb have covered the sizing issue well, so I won't retread that.

@MeganStevens the Renogy DC-DC is the awkward one in your setup — there's no clean way to get that into the Cerbo natively.

@PaulMurray I went second-hand on a couple of 100Ah cells for my garden office build — bought from a reputable eBay seller with capacity test results included.

Not Scotland but I've done two winters on the Pennines with a Multiplus-II and Fogstar bank, which I reckon gives comparable misery levels!

WonkyWarden | 1,203 posts | 🔋 Off-Grid Convert @BitsAndBobs worth checking your absorption voltage threshold and re-bulk voltage settings in the VictronConnect app.

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...
