Photovoltaic System Troubleshooting: Replacement of Enphase and APsystems Microinverters

Micro-inverter troubleshooting and replacement in Mouans-Sartoux et Montauroux

This week, REGIS ELECTRIC carried out two photovoltaic system interventions in the South of France, involving the replacement of faulty microinverters on existing solar installations.

The projects took place in Mouans-Sartoux and Montauroux, on systems equipped with microinverters from leading manufacturers:

• Enphase Energy

• APsystems

Photovoltaic troubleshooting in Mouans-Sartoux: faulty Enphase microinverter

In Mouans-Sartoux, our team was called in after a drop in solar production caused by a faulty Enphase microinverter.

Our intervention

• Accurate diagnosis using the monitoring system

• Quick identification of the defective Enphase microinverter

• Full management of the Enphase manufacturer warranty claim

• Fast replacement of the faulty unit

• Immediate recommissioning of the photovoltaic system

Thanks to our in-depth knowledge of Enphase systems, the client was able to benefit fully from the manufacturer’s warranty, without unnecessary delays or costs.

Photovoltaic troubleshooting in Montauroux: faulty APsystems microinverter

In Montauroux, REGIS ELECTRIC intervened on a photovoltaic installation equipped with APsystems microinverters, following a production fault on one panel.

Work carried out

• Full analysis of the photovoltaic system

• Identification of the faulty APsystems microinverter

• Complete handling of the APsystems warranty process

Frequently Asked Questions – Photovoltaic Troubleshooting & Micro-Inverters

1. How can I tell if an Enphase or APsystems micro-inverter is faulty?

A drop in production on a single panel, an alert in the monitoring system, or zero output from one module usually indicates a faulty micro-inverter. A professional diagnostic is required to confirm the issue.

2. Can a micro-inverter be replaced without dismantling the entire solar installation?

Yes. Micro-inverters can be replaced individually without removing the full photovoltaic system. When performed by a qualified installer, the intervention is fast and targeted.

3. Are Enphase and APsystems micro-inverters covered by manufacturer warranties?

Yes. Enphase and APsystems micro-inverters typically come with long manufacturer warranties. An experienced installer can handle warranty claims and manage the replacement process.

4. Will the solar installation continue to produce energy if one micro-inverter fails?

Yes. One of the main advantages of micro-inverter systems is that a failure on one module does not stop the entire system. However, the loss of production should be corrected quickly to maintain optimal performance.

5. Does REGIS ELECTRIC provide photovoltaic troubleshooting in the Alpes-Maritimes and Var areas?

Yes. REGIS ELECTRIC provides photovoltaic diagnostics and micro-inverter replacement services in Mouans-Sartoux, Montauroux, the Alpes-Maritimes, and the Var, including installations completed by other companies.

Is your photovoltaic system underperforming?

If your solar installation is producing less energy or showing a fault, REGIS ELECTRIC can provide a fast photovoltaic diagnosis and handle warranty-based microinverter replacement whenever applicable.
