6 FAQs about [The photovoltaic inverter keeps displaying self-test]

How do I know if my solar inverter is working?

How to maintain a faulty solar inverter display?

To maintain a faulty solar inverter display, you can proceed with the following steps: Begin with turning off the input PV switch on the photovoltaic inverter side. Next, disconnect the PV input DC switch and finally, switch off the battery switch.

Why should a solar inverter be inspected regularly?

Regular inspection is essential to avoid potential malfunctions that could affect the performance of inverter. Solar energy is a sustainable power source, with inverters converting sunlight into electricity. These devices are crucial components of a power system, but they can encounter issues from time to time.

How do I check if an inverter is isolated?

To display information about the inverter , right-click on the inverter and select Info. In the General parameter list, check Last Isolation Value. If an isolation error occurs, error 18x86 (single phase inverters) or 8x58 (three phase inverters) is displayed in the SetApp Status screen (see following figures).

What happens if an inverter fails?

Internal failure might cause problems that could lead to the inverter switching on and off. When turned on, the inverter will perform a self-test sequence to detect unusual input circumstances or an overload on its output side. The problem code is displayed on liquid crystal screens that are installed in modern inverters.

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.
