TERRENCE P

Unfortunately he can't understand you and neither can I. Adjust VOC Upwards to Minus 5 Deg ???. Sorry for being Dumb.
He did see the inverter sticker etc . Now the installation is on hold ..... will cost me another call out but I can live with that to do the right thing here  

Thank you so much for the response. Now I have a situation on my hands.
With the components mentioned what would you advise. Unfortunately the inverter and batteries have already been installed and working.

Hi Guys,
Some advice from you Solar Gurus Please. Easy one.
INVERTER
5KW OC ( AXPERT KING FAMILY )
Solar Charge - 80 Amps
Min Input solar      - 40 Vdc
Max input solar     - 145 Vdc
PANELS CS-585w-N   X 6
Operating voltage        - 43.3 vdc
open circuit voltage     - 52.4 vdc
operating current         - 13.52 Amps
Short Circuit current    - 14 Amps
SO HERE IS THE QUESTION
My installer wants to use 2 strings of 3 in series then parallel into a 1 in 1 out combiner box .
With OSV the input voltage is  157.2 vdc And 27 Amps. ( Operating voltage will be 129.9 vdc ) He says this is perfectly fine and the higher ocv is nothing.
We initially asked him for 3 strings of 2 in series into a 3 string combiner box.
With this OSV is 104.8 and 40 Amps.   We assumed that this was safest for these problematic Axpert  inverters. But the installer says that this is a waste and too expensive.
Some advise will be much appreciated here as I want to address it before the connections begin.
