  • PV inverter string data lost

    PV inverter string data lost

    In order to identify an event of a string disconnection in mini-central systems (such as SMA, Fronius, Fimer) a comparative analysis of inverter current or power data is necessary, or alternatively a physical inspection of fuses/switches from time to time. Both 2-in-1 PV strings are lost. Check whether cables are properly connected to the inverter terminals. The status can be Unidentified, Not connected, Single string, 2-in-1 string, Lost string, 2-in-1 string – full loss, or 2-in-1 string – single string loss. Enable this function if you need to. The most common solar string design mistakes are: undersized conductors causing voltage drop, strings with mixed panel orientations creating mismatch losses, VOC exceeding inverter maximum input at low temperatures, and insufficient inter-row spacing causing shading. String design errors are. The mismatch loss is defined as the difference between the sum of all Pmpp of each independent sub-module, and the Pmpp of the resulting I/V characteristics of the array.
