13.1.2 Grid Monitoring/Grid Limits
UL listing
The default limiting values for the line voltage and the power frequency are configured in accordance with
IEEE 1547, as required for UL1741 certification. The parameters for these limiting values are marked with ** in this
section. These parameters may only be changed by authorized personnel at the written direction of the utility. The
inverter can be operated outside the IEEE 1547 limits when required by the utility without loss of UL certification.
• Do not make any changes to the default limiting values for the grid monitoring parameters unless directed by
the utility.
• Inverter capability range shown in {brackets}
• 50 Hz values shown in [brackets]
• Grid monitoring measurement accuracy:
– Voltage measurement: +/– 8.5 V
– Frequency measurement: +/– 0.06 Hz
– Disconnect time: +/–4.5%
