Noticed something on my motorhome setup recently that had me scratching my head for a good while, so thought I'd throw it out here. I've got a Victron SmartSolar MPPT 100/20 paired with a 100W...
Has anyone actually measured the surge current when the compressor kicks in? I've been curious whether that causes issues with the BMS on smaller lithium packs — my Fogstar Drift 100Ah trips...

Done exactly this sort of setup on my narrowboat and garden office, so fairly familiar with the 12V lighting rabbit hole. Honestly, the easiest starting point is a simple fused distribution block...

@BoatIan the boat story is exactly the cautionary tale I needed when I was fitting out the Kangoo. Didn't listen, obviously. Here's the thing nobody mentions about cheap PWM units — it's not just...

Had exactly this on my narrowboat last summer — Victron SmartSolar 100/30 deciding it was done by 11am like it had somewhere better to be. Turned out my absorption voltage was set too low for my...
@LazyBodger the AUX input is a bit of a rabbit hole tbh. What are you trying to monitor with it — second battery, midpoint, or temp sensor?
@HarbourKev the shepherd's hut I power runs a single MultiPlus-II 3000 and even that single-phase setup had me drowning in G98 notifications and DNO correspondence for months — I genuinely can't...

@Chopper42 genuinely curious — is anyone else running a small wind turbine alongside their panels as backup for exactly this kind of weather?

@GemmaWood this is something I ran into building out my tiny house system last year. The key thing worth checking is whether your Cerbo's time sync is solid — I had Dynamic ESS making genuinely...

@GrumpyBuilder the Bluetooth sync dropout is the bane of my existence — my Smart Battery Sense in the static caravan does the same thing whenever my neighbour's dog presumably sits on the WiFi...

Spent three months going back and forth with my local council who seemed convinced my 400W of Renogy panels were somehow going to blind passing aircraft.

@FormerMariner what firmware version are you on? I hit something similar on my narrowboat when I bodged together a secondary monitoring setup and half the temperature readings were showing in...
Been mulling this one over for a while as it's relevant to my shepherd's hut setup, where I'm running a 12V leisure system alongside a separate 24V inverter bank — each with their own Cerbo GX...

Two MPPTs on the same array without proper load sharing is just two blokes arguing over the TV remote — someone's always losing. The VE.Smart Networking on Victron gear does help them play nicely,...

Running a similar setup on my boat and honestly it depends entirely on what you're powering. What are you planning to run in the hut?

Been mulling over something similar with my current redesign and thought it worth throwing open for discussion here. I'm running three 200W panels in series — combined Voc sits around 112V, which...

Got this running on my garden office Pi for about six months — JK BMS comms over RS485 are solid once you sort the USB adapter.
@MarineAlan two Cubix Pros in parallel is fine until one BMS gets a strop on and decides it's having the day off while the other one sweats through all the work — ask me how I know 😅

Running a Fogstar Drift 200Ah on my narrowboat and eyeing up a small chest freezer for the summer — anyone actually done the maths on whether that's a realistic overnight setup? The freezer I'm...

Had this exact saga on my narrowboat last winter. Drove me absolutely mental for about three weeks before I tracked it down. Turned out my Dynamic Current Limiter was enabled and causing the...
