6.2.2 Checking and measurement
Once the equipment has connected to the grid, the green LED will remain
on. Check the display to ensure that no error-indicating LED is on.
Check that the monitoring menu parameters are coherent:
• The PV array voltage must be between 300 and 600 Vdc and must
continue to be balanced (similar PVP and PVN values).
• The Vac voltage indicated on the display must be within the operating
ranges.
• The grid frequency must be 50 or 60 Hz.
• The RMS value of the lac1, lac2 and lac3 currents shown must be
similar.
• There must be no alarm displayed on the inverter (Alarm 0000H).
It is always advisable to use a current clamp to check the wave form of
the current generated in the three phases. To make this measurement,
it is mandatory to use the PPE indicated in IMPORTANT SAFETY
INSTRUCTIONS.
