Anti-Islanding detection methods: Frequency, voltage and utility impedance.
Build-in MPPT (Maximum Power Point Tracking) function.
High efficiency with wide range operation.
Design to meet VDE0126-1-1 requirements.
Easy assembly in production line.
Easy replacement when servicing. The mean time of service is less than
Firmware flash capability: The firmware inside the micro-controllers can be updated by optional communication interface.
GFCI: Ground Fault Current Interruption, which is also known as RCD (Residual Current Device). To prevent electrical hazard of user, a current transformer monitoring the difference between L and N current is applied. When the current difference is larger than specified value stated in section ¡§General Data¡¨, inverter will cut its output to grid.
Bundled software for user buying optional communication card.
