AH is the capacity of battary. The relationship between battary capacity and power quantity is as below: 1kWH=1000W*H=1000V*AH(V: voltage; A: Current; H: hour)

1.Keep cooling of all component,such as panels,distribution box,inverter.A water spray cooling device can be installed around the components.

2.Set up a sunshade for inverter.When installing inverters and distribution boxes, it is better to install them in places with sunshade and rain shelter.

32.

The maximum operating temperature of IGBT is 85 ℃.The maximum operating temperature of the phase-shifting transformer is 110℃

The current maximum power unit rating is 722A

The possible causes of this failure are:
1. The keypad is damaged or the keypad cable is not connected properly, so the keypad and keypad cable can be replaced and powered on again;
2. If the control board fails, the control board can be replaced and powered on again;
3. The connection line of the drive board is not in good contact, so it can be re connected and powered on;
4. The power supply of the drive board fails, and the power supply of the drive board can be replaced.

In the operation of the motor, the running current exceeds the rated value but is less than the over-current limit value, and the operation time is longer, which is called overload.

The basic characteristics of overload are: Although the current exceeds the rated value, the excess amplitude is not large, and generally does not form a large impact current (otherwise, it will become an over-current fault). Another significant feature of overload is that there is a time accumulation process. When the accumulation time reaches, the overload fault is reported.

Solution: Check the VFD's power/current is bigger than the load or not.

Make sure that the grounding is good. And use shielded cables, separate power cables and control cables, or add EMC filters or magnetic rings.
