High-Power Smart Inverter ATS

Multi-Channel Smart Inverter ATS

The Smart Inverter ATS can meet the electrical performance test of relevant grid-connected test standards such as IEEE 1547.1, EN 50530, NB/T 32004, CNS 15382 and CNS 15599.

The system is designed according to the specifications of various standards, and has built-in the test items into the system. The tests include abnormal voltage and frequency test, synchronization test, open phase test, reconnect test and harmonics test.

Preen’s Smart Inverter ATS can test PV inverter’s input voltage up to 2000Vdc, grid tied voltage up to 600V (L-L) and output power up to 2000kW. Moreover, all test data are saved in the system for further analysis and comparison.

The Multi-Channel Smart Inverter ATS can effectively simulate multiple solar panels. Each channel can be independently controlled and configured with different sunlight and temperature condition and it is ideal for maximum power point tracking efficiency (MPPT) testing.
