PV Inverter testing

We test inverters and other PV systems with MPP tracking device according to EN50530 and EN61683 standards. PV array simulator Spitzenberger&Spies PVS7000 is used to simulate the characteristics of a PV array, up to 7 kW, and Zimmer LMG95 is used to measure grid voltage and current.

PV simulator characteristics:

• Maximum output voltage: 950 V
• Maximum output current: 22A
• Maximum output power: 7 kW
• Current limits for voltage ranges
  
  • 200V/22A
  • 400V/22A
  • 600V/14A
  • 800V/11A
  • 950V/9,25A

Available tests:

• Static MPP efficiency
• Dynamic MPP efficiency
• Static power conversion efficiency
• ETA efficiency calculation
• Startup & Shutdown test
• Higher harmonics measurements of grid current
• Power factor measurements
