I've seen various references to modpoll (which is great for cross paltform) but wanted something a bit more graphical. Found this tool useful for poking around the modbus data via either LAN or RS485. This screen shot is showing data pulled from my inverter using the LAN with the inverter at 192.168.0.31.
There is a Master and Slave module. The master module is what you want to pull data from the inverter to see what's going on. The communication log shows you what's going on, error codes etc.
You can download it from github: https://github.com/ClassicDIY/ModbusTool
