What it means

Inconsistent parallel settings

Cause: The parallel configuration is set up wrong across the group — typically a mix-up between single-phase parallel and three-phase group settings on the units.

How to fix it

Single-phase parallel system and group three-phase system setup error.

T-REX-10KHP3G01

InverterFault

What it means

The inverter Settings are inconsistent — Inverter settings differ between parallel units.

Cause: Parallel inverter settings differ between units.

How to fix it

  1. Through the LCD control button on the inverter, the parameters of the machine are set to the same as those of other machines.
  2. If the problem persists, contact the after-sales service.

T-REX-50KHP3G01

InverterFault

What it means

Inverter overcurrent fault — Inverter current is too high, check the given power and load size.

Cause: Inverter output current tripped the hardware overcurrent protection, which acts independently of the firmware — a fast surge from the load side or a fault in the output stage.

How to fix it

  1. Power down the inverter, wait 5 minutes for capacitors to discharge, then restart.
  2. If the fault recurs immediately or repeatedly, record the exact code and contact your installer or the manufacturer's service line.
