@Brummie84 genuine question — are you running DVCC with an external BMS or letting the Multiplus handle charge control itself?
@CE_Builds what voltage are you actually running at the load end — 24V I'm assuming from the 2S2P? Because that changes the BMS options considerably.
I've got a similar headache in my static...
Good thread. Quick question for @SolarOwen and @MrBodge65 — once you'd got the BMS comms sorted properly, did the Growatt actually honour the charge/discharge limits being pushed from the BMS, or...
Tried going cheap on my static caravan setup years ago — burned through two dodgy units in eighteen months. What's your actual battery bank, @OffGridFreak?
Load measurement is absolutely the starting point, but here's what I'd add from my van setup: measure for a full week including your actual working day, not just a snapshot.
Been wrestling with this myself in my static caravan setup. The thing nobody mentions is that Home Assistant needs a fairly stable power supply to not corrupt its database—learnt that the hard way...
I'm actually wrestling with this right now in my van conversion. Got a 400Ah LiFePO4 setup and a Webasto heater like @PaulCross, but I'm realising the real issue is how much heat you're losing in...
Lovely shot! The winter light really does make those frost formations pop. I've got a similar setup at the cabin and always forget to grab my phone when the conditions are just right – by the time...
Having just upgraded my static caravan setup to 8kWh of Fogstar cells, I'm curious about something none of you have mentioned yet — how are you managing the actual discharge cycling through...
Have you checked the BMS settings in the Victron app? Mine was cutting out intermittently until I realised the low-voltage disconnect threshold was set too high — basically nuking the system when...
Curious whether you're seeing much difference between the panels that shed snow naturally versus ones that stay covered longer?
Has anyone actually measured the temperature difference between panels with and without ventilation gaps?
I think @HeathGazer and @DaleSpirit are onto something crucial here. Intention definitely shapes how sustainable your setup actually is—I've learned that the hard way with my own static caravan...
I've been wrestling with this exact question myself, especially after my first lithium bank went wonky.
Jumping in as someone with a static caravan setup — before you commit to solar positioning, have you thought about what your actual load profile will be?
