Because the PV array rarely produces power to its STC capacity, it is common practice and often economically advantageous to size the inverter to be less than the PV array. This ratio of PV to inverter power is measured as the DC/AC ratio. A healthy design will typically have a DC/AC ratio of 1.25. [pdf]

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 increases the inverter’s DC voltage. There are other causes of DC overvoltage, however. POSSIBLE FIXES: 1. Turn the. .
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. The "DC Over Voltage" error means the DC input voltage from the solar strings exceeds the inverter's limits. Why it's Problematic: High DC voltage can damage the inverter, potentially leading to costly repairs or replacements. It presents a serious safety hazard due to the high electrical potential. [pdf]

Lets start at the basics. You probably know that there are two different types of electrical power is use which are Direct current (DC), which is supplied by batteries and solar panels etc. This type of power is mainly used by small digital goods with circuit boards etc. The other type of. .
A common and fairly simple application of inverters is within photovoltaic arrays, as these generate DC power, but, the appliances in your home will use AC power so this needs to be converted for it to be of use. You can. .
Lets consider a simplified circuit where a DC source is being used to power an AC load. To convert the DC to AC there are 4 switches. The. .
If we take a closer look at the IGBT’s we’ll see that they actually open and close in a pulsating manner multiple times per cycle. This is known as. An Inverter Drive (VFD) works by taking AC mains (single or three phase) and first rectifying it into DC, the DC is usually smoothed with Capacitors and often a DC choke before it is connected to a network of Power Transistors to turn it into three phases for the motor.
