1. The high-quality AC output is guaranteed by the advanced hardware topology and software algorithm, with the output power factor closing to 1 ( the maximum power factor of 0.997) and the harmonic distortion of output current below 5%.

2.The high-quality electronics (like the 1200V silicon carbide rectifier diode and the aerospace-grade EMI elements) ensure the stable performance and the ultra-long service life of the product.

3.The internal electronics are completely isolated from the atmosphere by full pouring sealants, which protects the elements from dust and damp, and significantly reduces the deteriorating speed of the electronics.

4. Diversified high-precision sensors (input voltage monitoring sensor, input current monitoring sensor, grid voltage monitoring sensor, grid frequency and phase monitoring sensor, output current monitoring sensor and internal temperature monitoring sensor) provide the capability of real-time monitoring of multiple parameters.

5.The improved MPPT algorithm is featured with rapid response and high tracing efficiency of 99%.

6.The dual AC output port can be used to connect another inverter in series easily and quickly.

7.The build-in radio communication feature makes it possible to establish a monitoring system without the need of cabling or filters for carrier wave communication.

8.The ISM band radio communication requires no permission nor any additional charges.

9.The supporting data collector with LCD user interface is able to collect wireless data from 300 nearby inverters in maximum, or upload the data to the internet to establish a remote monitoring system accessible globally (see the user manual of the data collector, or resort to the supplier for more information).

10. Effective protection features and detailed information display make sure the user learns the situation clearly and quickly.
