Recently, Zeversolar received some good news, the NSG-500K3TL-20 inverter designed by Zeversolar successfully passed the NESC’s ZVRT test. This is a new milestone for Zeversolar after having become a part of the SMA group.

The ZVRT test is a Low Voltage Ride Through test that includes a Zero Voltage Ride Through test. These tests run under symmetric three phase fault and asymmetric single phase fault conditions .The Zeversolar NSG-500K3TL-20 can uninterruptedly stay connected to the grid during falling voltage with recovering periods of all test points. No matter what kind of fault appears, it can generate reactive current as required to support the grid and recover to the previous active power quickly after the fault clearance.

The NSG-500K3TL-20 made qualitative progress from the original functions. It has adopted advanced circuit topology and long-life components and provides high conversion efficiency. With a high speed and precision control chip, it has reactive power compensation and harmonic suppression functions. It also comes with a rapid and reliable over-current, over-voltage temperature protection function .The system has run up to 100,000 hours with out error .At present, the NSG-500K3TL-20 has become the flagship product in the Chinese domestic market, everyone love it because of its high conversion rate and high stability.
