INVOLAR Corporation hereby certifies the following in reference to the
above product:
1) It fulfills all the safety requirements according to IEC62109 -1 “Safety of power
converters for use in photovoltaic power systems”;
2) In case of power failure on the part of the power grid, it shall shut down and stop
outputting voltage and current;
3) It fulfills the following requirements according to EN50438 “Requirement for the
connection of micro-generators in parallel with public low-voltage distribution
networks”:
a) An automatic (re-)connection to the public grid is performed, provided that
the grid voltage and frequency are within the range of 184-264V (-20 % and
+15% of 230V) and 49.5 Hz–50.5Hz (±0.5Hz of 50Hz), respectively;
b) An immediate (< 0.2 s) disconnection is performed by the inverter, if the
voltage, or the frequency or both are not within the limits of 184-264V or
49.5 Hz–50.5Hz, respectively;
c) Reconnection time after clearance of grid failure is no less than 180 seconds;
4) The total harmonic distortion of the output current (THD) is less than 3%.
