"In our civic society, the choice of a supplier in the immediate vicinity was essential for ethical, economic and social reasons. For 6 years, CEFEM solar inverters have efficiently equipped more than half of our photovoltaic plants. Their monitoring via the Cefem portal interface is simple and allows any fault to be detected without delay. The reactivity of the CEFEM engineering team is invaluable in providing solutions quickly and avoiding significant operating losses. And this occurs throughout the life span of the material."
