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.
Range: 244.0 V–258.0 V
The default value of 10 Min Vtg is 248.0 V for New Zealand (code "NZ"). Refer
to the following table for different grid standards in Australia.
