Gazipaşa Solar Plant: 5 Faulty Inverters Replaced, Fault Service

Project summary

This page describes a service job, not an installation. According to the Instagram post dated August 2026, Solar Nexo first carried out a technical inspection at an existing solar power plant in Gazipaşa, then replaced 5 faulty inverters and recommissioned the system safely and efficiently. Who built the plant, its capacity and the inverter brand are not stated in the post.

System components and work done

Why is this service carried out this way?

In a solar plant, the inverter is the component that converts DC energy into AC energy suitable for the grid; when it fails, the panel strings connected to it cannot produce. In a multi-inverter plant a fault can stay at a single point or spread across several inverters. In this project 5 inverters had to be replaced; whether the faults had a common cause is not stated in the post. In general engineering practice, multiple inverter failures in the same plant call for a root-cause investigation before replacement. Otherwise a new inverter can fail again for the same reason.

A root-cause investigation typically checks the following: DC string voltages and currents, insulation resistance, earthing, surge protection (surge arresters), cooling and fan condition, ventilation and ambient temperature, connector heating, AC-side cabling and grid voltage. This is a general checklist; which of them was the source of the fault at this plant is not known.

Sequence matters in service work. First a technical inspection is made and the fault is identified. Then, with the power cut, the inverter is safely removed, the new one is fitted and the parameters are set. At commissioning, DC and AC values are measured and the connection to the monitoring system is checked. From a safety standpoint, the fact that the DC side stays live in daylight shows that this work must be done only by a competent field team.

Another aspect of service work is documentation. In an inverter replacement, the old device's serial number, its fault code and the details of the new device are recorded; the device definition in the monitoring system is updated. These records are used both in warranty processes and in the next maintenance plan. Because the records for this plant are not in the post, their contents are not known.

Effect of downtime on production

Every day of outage means lost production. According to PVGIS, from the central Antalya reference of 1,656 kWh/kWp/year, the annual average daily production is about 4.5 kWh/kWp; in July this value is about 5.4 kWh/kWp (168 / 31). As an example calculation, 100 kWp of faulty capacity corresponds to a theoretical production loss of about 540 kWh per day on summer days. Because this plant's capacity is not known, this is only to show scale; it is a theoretical calculation, and the real loss varies with the weather and the condition of the plant.

Service and commissioning process

Solar Nexo's maintenance and repair service starts with a technical inspection, equipment replacement is planned according to the fault diagnosis, and finally the system is recommissioned. 7/24 technical support and maintenance continue afterwards. Inverter warranty varies by brand and contract; for example, the standard warranty on TommaTech on-grid and hybrid inverters is 5 years from the invoice date (manufacturer document), but the inverter brand at this plant is not known.

For a similar service

Our solar plant maintenance and repair service applies to plant owners whose output has dropped, whose inverter shows errors or whose plant has had no maintenance for years. Our inverter fault article, our maintenance guide and our Gazipaşa article give details. The references, the calculation tool and the contact pages can also be used.

Estimated yields are theoretical values based on PVGIS 5.3 data (EU Joint Research Centre); actual output depends on roof orientation, tilt, shading and temperature.
