6 FAQs about [Photovoltaic inverter iso error]

What causes PV ISO-pro error?

Troubleshooting - The error commonly reflects a ground fault. Please check PV wires for grounding or shorts. Inadequately rated wire may cause the PV ISO-PRO error to continue. Please check the inverter for any grounding occurring internally. Did you find it helpful? Yes No

What does PV ISO pro mean?

PV ISO PRO means the resistance in DC side (solar) is too low on one or more strings. The ground fault will need to be resolved before the system can be energized. or the inverter will be damaged by it. PV ISO-PRO01 - Negative wire is connected to ground PV ISO-PRO02 - Positive wire is connected to ground 1. Check the inverter

Why is my inverter not converting power?

The error message that appears on the inverter screen is “isolation error” or “isolation fault”. For safety reasons, as long as this fault exists, the inverter will not convert any power as there may be life-threatening current on the conductive parts of the system.

How do I know if my inverter has an Isolation Fault?

You can identify an isolation fault using either SetAPP or the inverter LCD display. An isolation fault may disappear and recur after a short period (especially if it is caused by morning moisture), therefore it is recommended to troubleshoot the fault as soon as it occurs before it disappears.

How do I troubleshoot a PV system with a ground fault?

Extreme caution must be used when troubleshooting PV systems with ground faults. To comply with NEN-EN-IEC 62446 test the string resistance using the insulation tester at 1000V. Every time the SolarEdge inverter enters operational mode and starts producing power, the resistance between the ground and the DC current-carrying conductors is checked.

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.
