Danfoss TripleLynx TLX/TLX+

← PV, Battery, Grid, Meter

Communication uses the RS485 port of the inverter (ComLynx protocol).

Wiring (RJ45 connector on the inverter):

  • Pin 1: GND
  • Pin 2: B (RS485-)
  • Pin 3: A (RS485+)
  • Pin 6: B (daisy-chain to next device)
  • Pin 7: A (daisy-chain to next device)

Termination resistors (120 Ω) are required at both ends of the bus (bridge pins 4→6 and 5→7 on the inverter).

Connect a USB-RS485 adapter (or a network serial bridge) to the RS485 bus. For multiple inverters on one bus set the node parameter for each meter entry.

Usage areas

  • Solar production

Parameters

NameDescriptionValueLevel
deviceSerial port (USB-RS485 adapter)

e.g. /dev/ttyUSB0 — mutually exclusive with uri

Example: /dev/ttyUSB0
optional
uriTCP endpoint of a network RS485 bridge

e.g. rs485bridge.lan:4196 — mutually exclusive with device

Example: localhost:4196
optional
nodeInverter node address (hex, N-S-NN)

Only required when multiple inverters share the same RS485 bus. The address is discovered automatically on startup and printed to the log. Format: network-subnet-node in hex, e.g. c-6-b1

Example: c-6-b1
advanced
baudrateBaudrate

Typical values are 9600, 19200, 38400, 57600, 115200

Default: 19200
advanced
maxacpower [W]Maximum AC power of the hybrid inverter
Default: 0
Example: 5000
