Parameters
• Grid Under Voltage Levels
» Grid Under Voltage Level 1 - Transfer to FRT mode.
» Grid Under Voltage Level 2 - Inverter stops its operation with ‘Grid Under Voltage Level 2 Fault’ when the
grid voltage below ‘Grid Under Voltage Level 2’ sustains over “Grid Under Voltage Trip Time 2”.
» Grid Under Voltage Trip Time 1 - Permissible grid voltage under ‘Grid under Voltage Level 1’ time.
» Grid Under Voltage Trip Time 2 - Permissible grid voltage under ‘Grid Under Voltage Level 2’ time.
