If the setting is changed from ON to OFF, you should
set the protection voltage as specified in Tab. 7-3
according to local protection requirement.
If the grid voltage adjusting function is set to ON, the power derating
function for over-voltage 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.

The range of export power will automatically change:
When the existing inverter is disabled: 0 to (rated power of the inverter)
When the existing inverter is enabled:
The lower limit is the rated power of existing inverter.
The upper limit is ([rated power of the existing inverter] + rated power of the
inverter).
For example, retrofit an existing PV system (rated power: 2000 W) with
SG5K-D (rated power: 5000 W). The total export range will be 2000 W – 7000
W.
A prompt will appear when you set it for the second
