Growatt RS485 USB Cable

Get live data out of your Growatt inverter and into Home Assistant, ESPHome or your own software. This lead goes from the inverter's RS485 connection to a USB RS485 adapter. Growatt models differ, so choose the connector to match yours.

• RJ45: should fit Growatt hybrids with an RJ45 RS485 port
• Bare-ended (screw terminal): ferruled A, B and GND wires that should fit the green screw terminal used on many UK single-phase SPH models
• On SPH models, set the RS485 mode to VPP; the USB port can't be used for monitoring
• USB RS485 end, no drivers needed on most Linux/Raspberry Pi setups
• No radio, no cloud, just a wire

Check your inverter manual for the port and pin layout before connecting. Ask us if unsure.
