If SMA and Outback are the Rolls-Royce and Jaguar of solar inverters then Solar King is the Toyota. Slightly less features, not as flashy but suits a purpose and does it at a good price with industry-beating reliability.
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.
