Install Victron ET112 to monitor inverter usage

To no avail, I looked for videos or more thorough instructions beyond the simple diagram in the manual. I have installed the VenusGX to monitor the solar/battery and have the RS485- USB cable to connect the ET112.

Has anyone used the ET112 to monitor power usage of a non Victron inverter? My question is, I have 2/0 cable between my battery bank and the inverter and I do not see how to connect it in this system. AM I missing something here?

Any input would be greatly appreciated.

Hi, here is my setup, I hope the picture will help you. If I remember right, the main is connected on the top side left through the ET112 going out from the top side right, and the neutral is connected at the bottom, in parallel with the breaker. Here is the link for the installation :

Michelg,

Thanks for the response. What size/gage wire did you use for this? I assume that is not the prime cable between battery and inverter? is this a separate cable? The instructions do not provide much info regarding that and There is no way my 2/0 cable will fit.

Regards,

Hi @M Beach, I'm a bit worried you're mentioning a battery connection at all. There should be no battery connection to a ET112. The ET112 is a mains meter and should be on the output of the inverter.
