The optional parts for GD300L are DBU&DBR, Reactor, Filter, many kinds of PG card, LCD/LED keypad, IO card, STO card etc. Please refer to the attached optional parts list.

In order to select proper GD300L, need to collect the below information: motor parameters, encoder parametes, signals required between controller and GD300L, environment conditions, please refer to the attached table.

Photovoltaic panels also have efficiency degradation during actual use, such as shelter from leaves and dust on the surface of the photovoltaic panel, temperature, and mounting angle of the bracket. Regular cleaning of impurities on the surface of photovoltaic panels can increase the power generation rate.

How to solve the automatic trip of the AC circuit breaker:

The output circuit breaker tripping generally indicates that there is a short circuit in the circuit. Such a situation occurs frequently. It may be that the internal drive board of the inverter has a short circuit, and the drive board and IGBT need to be replaced.

Yes, non-standard software needs to be customized. Note that the three-phase 220VAC current is nearly twice as large as the 380VAC current, so it needs to be used at reduced power.

The mainstream of the anti-reverse solution is to use external CT and smart meters to realize the grid anti-reverse function. The smart meters adjust the output power of the inverter through 485 communication, and realize the self-generation of photovoltaic electricity. The plan requires the purchase of a special anti-reverse model, CT and smart meter, and the anti-reverse function need turned on in the settings.

1. Use multimeter to check whether IGBT is good according to the attachment.

2. Try to replace the control board with a new one.

   
   

Both GD100-PV and BPD support connect water level sensor, normally there are 2 water level sensors, full water sensor in water tank, and empty water sensor in well. The connection and control logic refer to the attachment file.
