BT-1 uses RS232 and RJ12. BT-2 uses RS485 and RJ45. They are not interchangeable.
Does it work with every Rover controller?
No. Rover generations use different communication ports. Match the exact controller model and label to Renogy's compatibility matrix.
Can I monitor from anywhere?
No. BT-1 provides local Bluetooth access. Remote cloud access requires different supported gateway and network hardware.
