Grid Protection Voltage Adjusting
All SUNGROW inverters are compliant with the local standard related to grid
protection requirements. In order to work with unstable utility grid, inverters are
equipped with automatic protection voltage adjusting function (disabled by
default). This mode can be enabled via the LCD.
OFF (default setting): the function is disabled. The grid protection voltage
cannot automatically adjust.
ON: enables the protection function. The inverter will automatically adjust the
protection threshold to a higher value so as to be normally connected to the grid
in the event of grid over-voltage. The V
max-rec
will be adjusted the same with the
V
max
, with an upper limit value not higher than V
max
.
If the setting is changed from ON to OFF, you must
set the protection voltage as specified in Tab. 7-3
according to local protection requirements.
If the automatic protection voltage adjusting function is set to ON, the
10-minute over-voltage protection function will be automatically
disabled.
If the line voltage or frequency goes outside pre-determined
parameters, the inverter must shut down for safety purposes, which
means it is not a faulty inverter in these instances. High line voltages
may damage home appliances and SUNGROW is not held responsible
or liable for these issues.
