Common Solar Inverter Error Codes & Solutions

Inverter failure can be caused by problems with the inverter itself (like worn out capacitors), problems with some other parts of the solar PV system (like the panels), and even by problems with elements outside the system (like grid

Tigo EI Inverter

This famous PV fire forever changed NEC 690 and PV inverter manufacturing. As a result, article 690.11 was added to the Code requiring all PV inverters to monitor AFCI faults. How are DC ground faults detected, diagnosed, and

How does an isolation fault occur and how do you resolve it?

In humid weather, the number of incidents involving systems with isolation faults increase. Tracking down such a fault is only possible at the moment it occurs. Often there will be an

How to find photovoltaic ground faults | Isolation

PV ground faults have a clear consequence. The fault makes the solar inverter, or combiner box shut down completely. Production is only reestablished, when Riso becomes sufficiently high again. For a residential PV

6 FAQs about [Photovoltaic inverter iso fault]

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.

What is an Isolation Fault in a SolarEdge system?

Modules with defective module isolation, unshielded wires, defective power optimizers, or an inverter internal fault can cause DC current leakage to the Ground (PE - protective earth). Such a fault is also called an isolation fault. This document describes how to identify and locate an isolation fault in a SolarEdge system.

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.

Can a transformer-less inverter cause DC current leakage?

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

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.

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
