On Grid Solar Inverter

Sunny Way SW series on grid solar inverter is designed to convert DC from PV modules into AC to power the load when the PV array is producing enough energy. It will switch automatically to feed the extra power to grid through a meter. Once the solar power is inadequate, the inverter will draw power from grid to power the load. You can apply the Sunny Way SW in single-phase or three-phase on grid as well as upgrade the systems at any time.
Unique Features
1. This on grid solar inverter detects islanding with active frequency offset, which improves grid-connection safety.
2. It applies high frequency link based on DSP (Digital Signal Processing) control technology. In addition, it is connectable in parallelmodularly extendable and extremely flexible for system configuration.
3. As it adopts the Mitsubishi IPM module of the 5th generation, this on grid solar inverter is impressively efficient. It also adopts self-optimizing MPPT to enhance the efficiency of PV system.
4. It employs LCD (Large Multilingual Graphic) and features simple configuration via keys with the configurable output voltage setup for world wide implementation.
5. This on grid solar inverter takes use of software calibration from DSP, which ensures a power factor of approximately 100%. Besides, the power production and CO2 emission reduction have been calculated up to 5 years.
6. Its full protections against every possible accident improve safety and reliability. In addition, it adopts easy commissioning from specialized remote setting and detecting software.
7. This on grid solar inverter adopts electrophoresis painting and clean design of IP65 protection rating which is suitable for both indoor and outdoor installation
