Overload capacity
Inverter overload capacity:
When the load less than 105
％
rated load, it runs normally.
When the load in the range of 105%~115
％
rated load, it will turns
to bypass 60min later.
When the load in the range of 116%~130
％
rated load, it will turns
to bypass 10min later.
When the load in the range of 131%~150
％
rated load, it will turns
to bypass 1min later.
When the load in the range of 151%~250
％
rated load, it will turns
to bypass 200ms later.
When the load greater than 251
％
rated load, it will turns to bypass
10ms later.
Bypass overload capacity:
When the load less than 130
％
rated load, it runs normally.
When the load in the range of 131%~150
％
rated load, it can
maintain 10min.
When the load greater than 150
