Description 2.1 Application 2 Description 2.1 Application The SINVERT PV inverter is a fully assembled, ready-to-connect inverter unit for PV installations. 1 2 3 Figure 2-1 Overview of PV system 1 The inverter transforms the DC voltage produced by the PV modules into an AC voltage. The AC output voltage is transformed to the grid voltage by a medium-voltage transformer. 2 The PV solar system can thus be connected to the medium-voltage grid. 3 8

Hardware operation 3.1 Commissioning the inverter 3 Hardware operation 3.1 Commissioning the inverter Commissioning an installation requires certain switching operations to be performed. This type of work must always be undertaken by qualified, properly trained personnel. Failure to perform switching operations correctly can result in significant property damage and serious physical injury. The components described in this manual operate at hazardous voltages and currents. Proper precauti

Hardware operation 3.2 Operating the inverter 3.2.2 Operating mode You can choose between modes "Automatic" and "Test". In Test mode, you can adjust the DC voltage manually. In Automatic mode, the inverter determines the Maximum Power Point (MPP) automatically. It also displays currently active fault messages. To select Test mode, turn the keyswitch to the "TEST" position. To select Automatic mode, turn the keyswitch to the "AUTO" position. 3.2.3 Switching the inverter on and off The i

Hardware operation 3.2 Operating the inverter 3.2.5 Fault reset You can reset a fault by turning the keyswitch from "AUTO" to "TEST" and back to "AUTO" or vice versa. If the inverter has been disabled due to a fault, it can now be activated again. 3.2.6 Displaying currently active alarms and faults In Automatic mode, you can display the last ten alarm and fault codes. To do this, press the OFF key in Automatic mode for more than 3 seconds. The alarm and fault codes will then appear in s

Hardware operation 3.2 Operating the inverter Maximum Power Point (LED "MPP") The power which can be generated by a PV system depends on the level of insolation and the temperature of the PV modules. The inverter control unit is equipped with a "Tracker" which automatically tracks the MPP (Maximum Power Point) of the PV field in Automatic mode. As soon as the inverter tracker has found the MPP, the LED "MPP" lights up. A flashing "MPP" LED indicates throttling of the inverter due to over
