I have above unit doesn't show the solar icon but there is 66vdc on the  pv terminals connected correctly.  Any idea how to solve this? When you scroll down to PV display shows 0v

Are you sure it's actually 66 V? Many 5 kVA Axpert firmwares compare the PV voltage to 60.0 V, and if less than that, report 0.0 V. Is your multimeter trusted?

Also, some models require about 150 V to start PV production. You didn't say what exact model yours is; presumably, one with a 145 V absolute max PV?

Thanks my meter is an old reliable fluke 77. Will be at the installation later and will get details.

Actually it's a CAP PowerStar 5000Va/48vdc/87A. Very similar to an Axpert Make in a nearby building. 

Utility charger rating 54V/30A/20A.

Solar Charger rating 60A, and Max Solar Voltage rating 105V.
