What is a 50/60 kW string inverter?

Datasheet50/60kW, 1000Vdc String Inverters for North AmericaThe 50 & 60kW (55 & 66kVA) medium-power CPS three-phase string inverters are desi ed for ground mount, large rooftop and carport applications. The units are high performance, advanced and reliable inverters desi

Why does my PV inverter need a new measurement?

The resistance between the PV strings and ground (PE) is too low for the inverter to be commissioned. This will force the inverter to make a new measurement after ten minutes. Make a visual inspection of all PV cables and modules for correct installation according to the installation manual.

How does a PV inverter work?

Connecting (green LED flashing) #52-53 Once the PV input voltage reaches the DC initial voltage, the inverter goes into operation. The inverter performs a series of internal self-tests, including measurement of the resistance between the PV array and ground. Meanwhile, it also monitors the grid parameters.

What happens if a PV inverter is disconnected?

DC voltages up to 1000 V are present in a PV system even when the inverter is disconnected from the utility grid. Faults or inappropriate use may lead to electric arcing. Only authorized personnel are permitted to repair or modify the inverter. To ensure personal safety, use only original spare parts available from the supplier.

What are the parameters of a smart string inverter?

Smart String Inverter Max. Input Voltage Max. Current per MPPT Max. Short Circuit Current per MPPT Max. AC Apparent Power Max. AC Active Power (cosφ=1) Max. Output Current Max. Total Harmonic Distortion Max. Operating Altitude

How does an inverter feed into a utility grid?

If the grid parameters are within the specifications during the required period (depending on the grid code), the inverter starts feeding into the utility grid. On grid (green LED glowing) #60 The inverter is connected to the AC grid and feeds into the grid. The inverter disconnects from the utility grid in the following cases:
