[RE-wrenches] Code compliant PV wire to an EcoFlow DELTA Pro Ultra Inverter/Charger

I can't see any way to do this. Some sort of metal conduit or metal clad
cable (not EMT specifically) is required by 690.31(D)(1) and I dont think
the PVHCS exception would apply to this. This is an issue with european
style inverters with direct MC4 connectors for the PV input.
Short of putting the entire inverter inside another box, or bolting a box
onto the outside of the inverter that enclosed the MC4 connectors....

Hi All,
I have a potential client who currently has an EcoFlow DELTA Pro Ultra
<https://www.ecoflow.com/us/delta-pro-ultra> inverter installed in his
house for battery backup. He wants to install roof-mounted PV. I don't see
how to connect PV into the Inverter/Charger using EMT for code compliance.
Has anyone done something similar? Can anyone think of a code-compliant
method to bring PV into this setup?
