AEG Power Solutions has introduced a new solar power inverter for utility-scale applications. The Protect PV.500 expands the company's product range for the utility-scale market and has certified efficiency yields 98.7% according to European standard 50530. With an appropriate transformer, it can also be adapted to the medium voltage grid (e.g. 10, 20, 33 kV), providing flexibility for a wider range of PV projects.
Utility-scale PV power plants require high-efficiency inverters to maximize operating yield while provide design flexibility to handle a wide variety of requirements. Scalability and advanced remote monitoring functions have become a key requirement.
Protect PV.500 is directly derived from the technology developed from AEG Power’s Protect PV.250 inverter, which has certified efficiency yields of 98,7% according to European standard 50530. With an appropriate transformer, it can also be adapted to the medium voltage grid (e.g. 10, 20, 33 kV). The Protect PV.500 is fully compliant with BDEW guidelines for energy producing installations and thus contributes to overall grid stability. Maximum Power Point Tracking is designed to meet the latest requirements for quick responses to dynamic weather conditions such as spontaneous cloud cover on a clear day, and reliable day/ night detection (active/passive). Monitoring and power plant integration is based on Modbus Protocol and advanced CAN BUS communication as well as via optic fiber and ethernet between the containers. This allows for cost-effective, safe and reliable remote monitoring and control of the PV plant. The monitoring and control system can be integrated into an overriding power station control technology.
Utility-scale PV power plants.
A key feature of the Protect PV product line is its power stack with advanced-design measuring and control technology enabling DC input voltages of up to 1000 VDC. Thin-film modules can therefore be used efficiently. The Protect PV.500 is also available as part of AEG PS’ turnkey container solution TKS-C 1000, which is equipped with two Protect PV.500 units.
