Replacement of inverters and installation of gross production meter Zonnepanelen Haarlemmermeer B.V.
Since 2014, Zonnepanelen Haarlemmermeer B.V. has installed more than 1,000 solar panel installations, of which 460 feature SAJ inverters and 614 feature Mastervolt inverters. In recent years, the Mastervolt inverters have not been functioning properly, leading to high failure rates and a non-operational online monitoring environment following the bankruptcy of Mastervolt. To improve reliability and maintenance, it has been decided to replace all inverters and add a gross production meter for proactive monitoring. The assignment concerns the supply of new inverters (preferably with robust, cloud-based monitoring), the installation of a gross production meter, and the decommissioning/disposal of the old inverters. The contracting authority expects a solution that complies with Dutch solar energy standards, offers easy integration with existing systems, and includes a clear service and maintenance arrangement.

01What is being requested
Since 2014, Zonnepanelen Haarlemmermeer B.V. has installed more than 1,000 solar panel installations, of which 460 feature SAJ inverters and 614 feature Mastervolt inverters. In recent years, the Mastervolt inverters have not been functioning properly, leading to high failure rates and a non-operational online monitoring environment following the bankruptcy of Mastervolt. To improve reliability and maintenance, it has been decided to replace all inverters and add a gross production meter for proactive monitoring. The assignment concerns the supply of new inverters (preferably with robust, cloud-based monitoring), the installation of a gross production meter, and the decommissioning/disposal of the old inverters. The contracting authority expects a solution that complies with Dutch solar energy standards, offers easy integration with existing systems, and includes a clear service and maintenance arrangement.
From 2014 to 2016, 1,074 installations were placed, of which 460 used a SAJ inverter and 614 used a Mastervolt inverter. During the recent period, primarily the Mastervolt inverters have not been functioning properly, resulting in frequent failures. Due to the bankruptcy of Mastervolt, the online monitoring environment is also no longer operational, which complicates corrective maintenance. Consequently, it has been decided to replace all inverters and also add an additional gross production meter for proactive monitoring.
