So I've hooked up everything and finally flipped the switch. Running 2 inverters in parallel. One inverter reads the 1st string properly. The other inverter is showing the pv array and only shows 2v. When I cut the 2nd string breaker off I get 224v. I get the 2v reading on both sides of the breaker when it is turned back on. Anyone ever hear of this. Oh, and I did disconnect the pv from the inverter and checked voltage and it was 2v with the breaker on. Is this a bad breaker?
 
Keep working your way back to the solar string, one bad connection, not fully seated, would leave you with an open circuit.
