6 FAQs about [The photovoltaic grid-connected inverter does not light up the screen]

Can a solar inverter cause a fault?

Like any piece of equipment, solar inverters can experience faults and errors that can disrupt the operation of the solar system. In this section, we will discuss some of the common error faults that may occur in a solar system inverter in Australia.

Why is a PV inverter NOT working?

The inverter in the PV system does a crucial job as it converts the DC power from the PV into AC power. If the inverter isn’t producing the correct voltage output, go check the DC input voltage first because the process starts there. It cannot produce the right output if it doesn’t get the right current input.

Can a solar inverter restart after a grid fault?

When the solar system encounters a grid fault, the inverter should be able to restart on itself after it comes online. After a sudden deactivation, the system trigger cut-out may occur at a voltage peak in the grid. Once it’s back online, the inverter should be able to restart on its own, or the service team has to come.

Can a transformer-less inverter cause DC current leakage to ground?

In photovoltaic systems with a transformer-less inverter, the DC is isolated from ground. Modules with defective module isolation, unshielded wires, defective Power Optimizers, or an inverter internal fault can cause DC current leakage to ground (PE - protective earth). Such a fault is also called an isolation fault.

What causes a solar inverter error?

Understanding the causes of these errors and how to troubleshoot and repair them is important for maintaining the efficiency and effectiveness of your solar system. This error occurs when the current flowing through the inverter is too high, and can be caused by a variety of factors such as a short circuit or a faulty solar panel.

Why does my SolarEdge inverter display an isolation error?

Every time the SolarEdge inverter enters operational mode and starts producing power, the resistance between ground and the DC current-carrying conductors is checked. The inverter displays an isolation error when it detects a total combined isolation resistance of less than 600kΩ in single phase inverters, or 1MΩ in three phase inverters.
