FAQs
CT, Grid & Operating Mode
- Q: What is the standard CT rating for the T-REX-50KHP3G1? What is the maximum CT supported by the inverter?
A: The standard CT is 300 A / 100 mA, and the maximum supported CT rating is 300 A. - Q: Can the 50K inverter limit the power drawn from the grid?
Yes. This can be achieved through the Grid Peak Shaving function. - Q: Can the 50K inverter operate without batteries?
A: Yes. The inverter can operate without batteries in grid-tied mode. - Q: Can the 50K inverter connect to a generator?
A: Yes, the 50K inverter can be connected to a generator.
Battery Connection & Compatibility
- Q: How should the batteries be connected when using 50K in parallel configuration 1 & 2?
A: Connect the battery packs to the inverter battery terminals through a DC breaker, following the battery wiring diagram for the parallel configuration. - Q: Can the 50K inverter work with two independent high-voltage battery clusters?
A: Yes. The 50K inverter has two independent battery ports. However, communication has only been tested with our own batteries, so compatibility with other battery brands cannot be guaranteed.
- Q: Can the 50K inverter operate at full load?
A: Yes, full-load operation is supported when only a small amount of inductive load is connected. Excessive inductive loads should be avoided.
Wiring, Communication & Modbus
- Q: If the CT is directly connected to the inverter, what is the maximum CT cable length and recommended cable size? If an external meter is used, what is the maximum communication cable length?
A: The CT cable length can be up to 10 m. The recommended cable size is 18 AWG. If an external meter is used, the communication cable length can be up to 1000 m. - Q: How should the DIP switches be set for CAN communication?
A: Set all SW1 DIP switches to ON, then restart the inverter after changing the DIP switch settings. - Q: How can the 50K inverter support Modbus data reading for integration with the customer’s smart home system?
A: The 50K inverter can be connected through the RS485 port. Use the following pins: Pin 3: 485_A3; Pin 4: 485_B3. - Q: What is the maximum length of the parallel communication cable?
A: The cable length should not exceed 40 m. A shorter cable is recommended for better stability.
Settings, Firmware & App Display
- Q: What is the default password for entering the settings menu?
A: The default password is 123456. - Q: The PV energy statistics of the 50K inverter show 0. How can this be resolved?
A: Upgrade the firmware to GD106 or above and Slave108 or above. - Q: If the 50K inverter is connected to microinverters, can the microinverter data be displayed in the app?
A: Yes. The Wi-Fi firmware should be upgraded to V2.12 or above first. - Q: The SN displayed on the inverter screen is different from the SN shown on Fsolar. How can this be fixed?
A: After upgrading the inverter, power off the unit and restart it.
Parallel Operation & Output Performance
- Q: What is the maximum number of 50K inverters that can be connected in parallel?
A: Up to 12 units can be connected in parallel. - Q: Does the 50K inverter support unbalanced output?
A: Yes, but with limits. If any phase reaches 110% of the balanced output power, it can operate for only 10 minutes. If any phase reaches 120%, it can operate for only 1 minute. - Q: What is the inverter’s self-consumption?
A: When the inverter is not started and has no output, with only the screen on, the standby consumption is about 19 W. When the inverter is running in off-grid mode with no load, the no-load consumption is about 210 W. Under load, the loss depends on inverter efficiency. The maximum inverter efficiency is 97.6%. - Q: The B55 grid phase sequence is reversed. How should this be handled?
A: Set the grid phase sequence type to reverse sequence in the inverter settings. Note: when two units are operating in parallel, both units must be set to positive sequence.
