delta solivia 3.0 tl

Any one that can help with issues it would be awesome and appreciate,  I just install 3 PV 280watts each and connect it to a breaker of 40 amps connected to my  delta solivia controller. I'm geting approx. 86.5 volt from the breaker as I use my voltmeter. but my controller is not giving any numbers that i'm getting any load from the PV.  The controller is connected to the grid now and its giving me info of the controller but 0 on the daily info on the PV what would be the best way to see if the PV and my controller is talking to each other?

What is the voltage range for your grid connected inverter? Usually it is about 120 volts as a kick in voltage... string inverters usually use 8 to 10 panels in series per string...
