Hi all,
I have installed a Axpert king 5K with 12 PV Panels 360W 39VDC each four strings so 3 PV panels in series. I am planning on adding an extra two strings to try make it more efficient 2 panels in series. We are currently getting really bad PV production due to shading on the strings a total of 500W to 650W 70VDC . Before i add another string would like to know if there are any optimizer that could be compatible with this inverter to increase the PV production? Would also like to know if anyone has used the Wifi card with this inverter supplied by Voltronic for remote monitoring. The blue tooth is not compatible with IPhone.
There is very little support with this inverter, any assistance will be appreciated
