How to use a Carlo Gavazzi meter with the Dura-i G3 for AC coupled installs?

The AC Couple function on the Dura-i Inverter is designed to allow the end user the ability to smartly control consumption and storage of energy generated by previously installed solar panels. The Dura-i will work with the already installed PV inverter to smartly allocate the generated power to be distributed more efficiently.

This guide covers all steps post inverter installation; therefore you must ensure the inverter is installed correctly before moving onto using the Carlo Gavazzi meter. 

The Carlo Gavazzi EM330 meter will be provided by Duracell Energy and will come pre wired. Before your install, you will need to contact Duracell Energy to obtain a meter for your install.
