NCSP Solar Energy – Extremely Disappointing After-Sales Service

Our experience with NCSP Solar Energy has been extremely disappointing, particularly when it comes to after-sales service and communication.

We had a 12kW Deye solar system installed, including three 5.12kWh batteries and 16 × 550W solar panels. We also have a separate solar system for our flat.

Unfortunately, we have experienced ongoing problems with the inverter. It has now been sent away for repairs four times.

We have also had issues with high municipal voltage, which reached approximately 260V, creating additional concerns about the safety and protection of our solar equipment and household appliances.

After the inverter's fourth return, we were hoping the problem had finally been resolved. Unfortunately, it is now giving us an E23 error. We contacted Deye regarding the error, and we were advised that it indicates a leakage fault between the solar/PV side and the grid.

What makes this situation even more frustrating is that NCSP Solar Energy is now not responding to our WhatsApp messages and is not answering our calls. We have repeatedly tried to contact them, but we are not receiving any response or meaningful assistance.

This is completely unacceptable after spending a substantial amount of money on a solar installation. We understand that electronic equipment can fail and that some problems can be caused by the municipal electricity supply. What we expect from the installer is proper troubleshooting, communication and after-sales support.

Instead, we have had an inverter that has gone in for repairs four times, ongoing technical problems, and now a new E23 fault — while the company we bought the system from is not answering our calls or WhatsApp messages.

We are still paying for the solar system while also having to purchase electricity when the system is not operating properly. This has resulted in a significant financial burden and enormous frustration.

A solar installation is a major investment. The service should not end once the installation has been paid for. Customers need to know that the installer will be there when something goes wrong.

At this point, based on our experience, we cannot recommend NCSP Solar Energy. The lack of communication and after-sales support has been extremely disappointing.

We hope NCSP will eventually contact us, take ownership of the outstanding issues and provide a proper solution rather than leaving us without support.
