The Sun2000-KTL-M0 inverters are three-phase, grid-tied, transformerless inverters from the Chinese corporation Huawei. With a maximum efficiency of 98.40 - 98.65% and ranging from 5k W to 15 kW, they are arguably the best inverters for converting DC power to usable AC power. [pdf]
This is caused by low intermediate circuit DC voltage. This can be caused by a missing supply voltage phase from a blown fuse or faulty isolator or contactor or internal rectifier bridge fault or simply low mains voltage. .
Overvoltage This is caused by a high intermediate circuit DC voltage. This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and. .
This is detected by an imbalance of the currents supplying the motor implying a leakage current to earth is present. This is usually caused by poor insulation resistance to earth. POSSIBLE FIXES: 1. Check insulation resistance of the motor and cabling. 2.. .
We hope you found the information in this article useful if you have a fault not listed and you need technical assistance contact our engineering team. .
This occurs when the motor is taking too much current with reference to the value in Group 99, motor data. POSSIBLE FIXES: 1. Check that motor’s load is not excessive. 2. Check acceleration time – too fast an acceleration of a high inertia load will cause too. [pdf]

A power inverter, inverter, or invertor is a device or circuitry that changes (DC) to (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of which were originally large electromechanical devices converting AC to DC. An inverter takes input from a DC (direct current) power supply and generates an AC (alternating current) output, typically at a voltage comparable to that of your standard mains supply. [pdf]
