What great service! Called on Wednesday about a malfunction of the solar panels! During the telephone conversation, they immediately checked whether they could solve the problem remotely. That was not the case and therefore an appointment was immediately made for a technician, who came the next day to examine the fault. The fault could only be resolved by installing a new inverter and that was done immediately! Just like 4 years ago when the solar panels were installed, we received great help again! M.H.B. Technology is highly recommended!
