6. The AC current of a reactive power capable inverter is phase shifted compared to the grid voltage The larger this line conductor angle or phase shift angle between power and voltage is the more reactive power is fed into the utility grid By multiplying the cosine function of the line conductor angle or phase shift angle with the apparent power voltage x current you can easily calculate the remaining active power This is why the value of cos p is also called displacement power factor Energy Usability Factor The energy usability factor indicates which proportion of the electrical energy supplied by the PV array can be used by the inverter and converted to alternating current The energy usability factor is not 100 if the inverter cannot process the entire PV array current in every operating situation due to current voltage or output limits For economic reasons an energy usability factor of 99 8 is desirable Genset Electric generator with a combustion engine e g diesel gas or petrol Independent Inputs Each independent input of an inverter has its own MPP tracker The operating point of the connected PV array can therefore be set independently of the operating points of PV arrays connected to other independent inputs Multi string inverters have at least two independent inputs Inverter A device for converting the direct current DC supplied by the PV array into alternating current AC which is necessary for connection
