Grid-tie Inverter test
Below are listed the types of grid-connect inverter tests:
1. Scintillation
2. DC component injection
3. Harmonics and waveform distortion
4. Power factor
5. Reactive power injection/demand
6. Over/under voltage
7. Over/under frequency
8. Active power control under over frequency
9. Reconnection
10. Out-of-phase reclosing
11. Active power modulation
12. Reactive power modulation
13. GCPV disconnection
14. Undervoltage supportability requirements due to grid faults
15. Efficiency
16. Protection against polarity inversion
17. Overload
18. Anti-islanding protection
The tests 1 to 14 are developed according to ABNT NBR PN 03:082.01-001 and PN 03:082.01-003 standards
The test 18 is developed according to ABNT NBR IEC 62116 standard.
Important:
The register of the product in INMETRO expires in 1 (one) year. The company must perform new tests in a laboratory accredited by INMETRO every year to keep the labeling of a particular model.
The report emitted by the laboratory accredited by INMETRO also expires in 1 (one) year. It is recommended that the company registers the product in INMETRO’s ORQUESTRA systems immediately after receiving the test report.
