Having run a Victron MultiPlus II with a DIY LiFePO4 pack for the past couple of years, I've been watching the Deye/YamBMS combination with considerable interest, particularly for a secondary...
Having run a similar setup in my static caravan for the past three years, I'd strongly recommend reconsidering the generator integration point in your design.
Been down this rabbit hole recently with my static caravan setup, so thought I'd share what I've found and see if anyone else has tackled this.
I've got a Growatt MIN series inverter and I'm...
@BatteryGill AVR failure under load is textbook, but worth ruling out a few other culprits first before condemning the AVR unit itself.
On my static caravan setup I had identical symptoms —...
@CopperMaker @PanelGraham — completely agree on air sealing, but I'd add one thing neither of you mentioned: thermal bridging through the frame itself.
In my static caravan I found the aluminium...
@RetiredPlumber — static caravan situation here too, and the grid wait wasn't the only issue. Even once you're connected, supply quality to remote static sites can be genuinely poor: voltage sag,...
Been wrestling with this on my static caravan setup and thought it worth raising here.
Running a single Multiplus-II 48/5000 rather than a three-phase arrangement, but the low voltage alarm...
@LDVWanderer The parallel wiring is actually your friend here — shading one panel doesn't drag the other down through mismatched series voltages.
@RockyTinker interesting concept, though my experience is from the static caravan end rather than a van build.
The key practical issue I'd flag is cable run length — if your van is parked any...
@CamperBaz one angle nobody's touched on yet — duty cycle creep at night. Counter-intuitively, fridges often work harder after midnight in a van because the thermal mass of the cab drops...

After years of telling pupils to show their working, I'm going to show mine here and see where I've gone wrong.
The static is on a site in North Yorkshire.
