*If the country code is "China", the grid type can be set to power plant/non-power plant.
Set the grid type to correct value according to definitions of power plant
scenario and non-power plant scenario. Otherwise, the inverter will run
abnormally or even be damaged, and SUNGROW shall not be held liable for any
damage caused.
Power plant scenario: The inverter is applied to a power plant whose
•
capacity is greater than 1 MW, or to a power plant that feeds power into the
grid at the voltage greater than 35KV and connects to the public power grid
at the voltage of 10KV.
Non-power plant scenario: application scenarios other than the power plant
•
scenario.
The definitions come from the national code "NB/T 32004", "GB-T19964".
