Proven performance
Our inverters are based on a proven design from one of the world’s largest solar inverter manufacturers. They are fully certified by TUV according to FINGRID class A to class D for use in installation from 1MW to above 30MW and for 110kV grid connections and support all frequency regulation modes as well as grid forming where required. The inverters have also been fully tested according to ELERING requirements for class A to class D installations.
Response time
From the time of issuance of a Modbus power command to our BESS container controller, it takes the inverters between 150ms and 300ms to reach the required power as measured by external fast meter. This includes power commands from maximal charge power to maximum discharge power. Faster response time are possible via optimization.
