Voltronic/Axpert RS232 USB Cable

A USB RS232 lead for Voltronic Axpert inverters and the many off-grid and hybrid models built on the Voltronic platform. It's also expected to suit lots of MPP Solar, EASun and PowMr units. Use it for local monitoring with Home Assistant, ESPHome or other software.

• Should fit Voltronic-protocol inverters with an RJ45 RS232/COM port
• Uses pins 1 and 2 (data) and pin 8 (ground). This is RS232, not RS485
• Published sources disagree on which of pins 1 and 2 is TX. If you get no data, check your model's manual or ask us before assuming a fault
• Voltronic protocol at 2400 baud is typical
• Not every Must or Sorotec model is Voltronic-based. Check your model first
