Low voltage certification
Low voltage certification with unit certificate as per application guide VDE-AR-N 4105:2
Compensation
Due to the requirements in German code of practice VDE-AR-N 4105:2018-11, operating own generating systems without reactive power compensation is only permitted in exceptional cases. A cos φ of 0.95 is achieved with the standard fixed compensation.
Feed-in management as per §14 EEG 2021
Reduction in feed-in power (0-10 V) possible by preselecting target value via analogue input, bus interface (optional) and digital inputs (to connect relay contacts on a ripple control receiver provided by customer).
Controller
