An excellent accessary to the Fronius inverter.

Performance and range appear to be consistent with claims and specifications. With the corresponding display, this system is definitely an asset as the customer has continuous access to system performance data at a convenient location.

One downside: The installation instructions submitted with the card are sketchy and generally inadequate. The installer is directed to install the card per the original system installation instructions. These instructions are often not available to the field installer. Specifically, the installer should have information regarding the procedure for assigning an acceptable (to the display) channel number.

Recommend that Fronius include full installation instructions with each card.
