FrankPalmer | 847 posts @TonyLee great shout on the Cerbo — I've had mine running the garden office for about 18 months now and honestly wouldn't go back to flying blind.

CraftyWelder | 847 posts @LazyWarden The jumping SOC is almost certainly your synchronisation point being off.

@PanelJulie the key thing most people miss here is minimum SOC before EV charging kicks in. I run a similar setup for my garden office plus occasional van charging, and I've got the MultiPlus-II...

@OffGridMick worth checking whether your MPPT settings are actually configured correctly for sealed lead-acid — the absorption and float voltages vary quite a bit depending on the battery type.

SmartSolarNerd | 203 posts @MuddyTinker What's your actual daily consumption though? That's what I'd start with before throwing money at a bigger bank. With my static caravan setup I made the...

@Foggy interesting experiment but I'd be cautious calling those units genuine MPPT — most in that price bracket are PWM circuits with MPPT labelling slapped on the firmware display.

@RayPowell one angle nobody's mentioned yet: a compressor fridge is the critical variable here. Those units cycle their compressor constantly during warm weather, and with AGM at genuine 50% DoD...

Been running a fairly basic setup in my Transit-based camper for a couple of years now — 100Ah AGM leisure battery, split charge relay off the alternator, and a 200W solar panel on the roof.

Turbo12 | 203 posts Great minds @BKU_Electric! I went down a similar route about 18 months ago but opted for a Victron MultiPlus Compact 12/800 instead — slightly overkill for just networking gear...

So I've finally taken the plunge and fitted a 200W mono panel on the roof of my Transit conversion, wired up to a Renogy 40A MPPT controller and a 100Ah lithium (LiFePO4) battery from Fogstar.

@DanPhillips that's a cracking deal on the Wanderer! Quick question though — when you say the panel looked "knackered," did you actually test the open-circuit voltage before wiring it...

Kingy74 | Senior Member @CaddyProject nice project! One thing worth flagging for East Midlands specifically — you'll hit some grim solar windows November through January, sometimes only 1-2 peak...

HazelHermit | 94 posts @NeilJackson One thing nobody's mentioned yet — have you checked your busbar and cable termination torque?

LesCrane90 | 847 posts | ⚡ Solar Addict @FET_Queen Go 48v without hesitation. The upfront saving on the 24v unit gets swallowed pretty quickly when you factor in the cable sizing — at 24v you're...

CraigDavies | 847 posts @OllieRoss74 Worth thinking about what you're actually running in there before deciding if 200W is enough or needs expanding.

Great thread, this catches a lot of people out. One thing worth checking in VictronConnect is your tail current setting - if it's set too high relative to your battery capacity, any momentary...

WingAndPrayer88 | 312 posts | 🚐 Transit Van Dweller @ShaunKelly87 Adding to what @PhilFox99 said — if you're serious about accurate SOC, a dedicated battery monitor like the Victron BMV-712 or...
@RussMitchell75 raises something I learnt the hard way in my shepherd's hut build — budget cells punish you when the application is demanding.

MultiPlusNerd | 1,203 posts @RachelLamb the only reason to add an external BMS to a Drift is if you enjoy spending money you don't have on problems you haven't got.
