I have a SolarX 4K and an Apex 300. Apparently it needs a specific cable (P090 on one end, bare wires on the other) to connect to the system. Where do you get that cable?

You’re right the SolarX 4K to Apex 300 connection usually needs the P090-to-bare-wire cable. Most people either order it directly from the inverter/distributor (some suppliers list it as an “RS485 communication cable”) or make one up themselves if they’re comfortable with wiring. If you’d rather not DIY, I’d recommend checking with your SolarX dealer or a local solar parts supplier they often carry the P090 pre-wired cables. Some folks have also had luck on Amazon or eBay by searching “P090 RS485 cable.”
To DIY you need the cable pinouts; I do not have them, nor have I seen them anywhere. Have you?
It is not available on the Bluetti website, or on Amazon/Ebay. Have you seen any such cables for sale anywhere?
