USB to RJ45 RS232 Inverter Monitoring Cable / Firmware Update Cable | Voltronic / Axpert / RCT / MPP / Infini Inverters
This cable is used to Monitor or Update firmware for multiple inverters.
5 Volt on Micro-USB monitoring is not very stable and voltage drops may be experienced when monitoring your inverters via micro-USB to USB on a PC or raspberry PI / Orange PI. The solution is to use this cable since USB to RJ45 RS232 is a 24/7 stable solution to monitor inverters and a wide range of inverters supported including Axpert 5k, RCT MK2 5kW, MK3 5kW, Axpert King, Voltronic Models, MPP Models, Infini Models.
RS232 (Serial Port, DB9) is a universal standard on all these brands of inverters and this cable can be used with these inverters for monitoring or for firmware updates from a PC / Laptop.
Example below of RS232 Port on RCT / Axpert inverter for Firmware update or Inverter Monitoring:
Values such as below can be obtained from a “dumb” inverter via the RS232 port using ICC or Solar Assistant or similar software
Please REMEMBER to set you monitoring software port if ICC or Solar Assistant used for monitoring. Any monitoring software must be set to monitor via RS232 port on inverter and NOT via micro-USB or USB Data Port.
