10-Minute Over-voltage Protection
ON: enables the protection function by default. The
inverter will automatically disconnect from the grid
within 3 s when the average voltage for a 10 min
period exceeds the set-point of 10 Min Over Vtg.
OFF: disables the function.

Volt-watt Response
The Volt-watt response mode is enabled by default.
Set four grid voltage reference values. The output power of the inverter will vary
in response to the grid voltages.
