Technical FAQs 4

What causes a solar inverter to fail?

This fault occurs when the solar inverter loses synchronization with the grid, either due to a grid failure or anomalies in the grid's voltage or frequency. These anomalies might include voltage levels that are too high or too low, or frequency deviations from the standard 50 or 60 Hz, depending on regional standards.

Why does my solar inverter automatically shut off?

A solar inverter is designed to handle a certain amount of power. If it exceeds that limit, it will automatically shut off. This is done as a safety precaution in order to protect the inverter and keep it from overheating. You can prevent your solar inverter from shutting off by ensuring that your system is not overloaded.

Can inverter failure cause a shutdown?

Inverter failure can lead to a shutdown, but most failures can be fixed by the installer or user with assistance available from the Aftersales team if needed. High voltage in the inverter or the residence can trigger automatic shutdowns, and proper setup of shut-down parameters and voltage drop is important to prevent this.

What happens if a solar inverter overloads?

An overload in a solar inverter occurs when the power input from the solar panels exceeds the inverter’s capacity to handle or convert it safely into output power. This condition can stress the inverter's components, such as capacitors and cooling systems, beyond their operational limits.
