The controller blue'Log XC is the key to improved grid integration of PV systems and thus reliably guarantees the grid connection. With extensive functions for active and reactive power management, grid-friendly feed-in is ensured and enables the PV system to provide ancillary services for grid stability. The scalability of the plant control based on the blue'Log XC allows flexible use of the controller from the low-voltage to the high-voltage level.

Active power management
Whether grid safety management to avoid grid bottlenecks or ensuring complete self-consumption (Zero Feed-In), the controller blue’Log XC contributes to system security with its flexibly configurable active power management.
- Active power curtailment to fixed / variable setpoint
- Interface for grid operator and third party (solar power trading)
- Ramp rate for active power output increase and decrease
- Soft start
- Fast stop
Reactive power management
By participating in static voltage maintenance, more PV systems can be integrated into existing grids. The targeted supply of reactive power is thus an essential component of the grid integration of renewable energies.
The blue’Log XC helps to actively maintain the voltage with its comprehensive reactive power management and thus significantly improves grid stability.
- Fixed setpoint control of reactive power or power factor cos φ
- Characteristic curve control cos φ (P), cos φ (V), Q (P), Q (V), Q (tan φ)
- Ramp rate for reactive power supply increase and decrease
- Reactive power compensation beyond feed‑in operation (at night)
The plant control can be analyzed in real-time on the controller itself and on the basis of historic measurement values with the help of VCOM or through the use of a wide range of data export options.
Parameterizing instead of programming.
The graphical user interface of the blue'Log X-Series will provide you with optimal support during commissioning and requires no programming knowledge on your part.
Thanks to the clear user interface and the industry-specific menu structure, you can easily and quickly comply with even complex grid connection regulations by parametrizing the controller blue’Log XC.
No matter whether you are talking about a mixed park or a heterogeneous portfolio – with the all-in-one driver of the blue'Log X-Series you can meet the requirements of high protocol variety with a maximum level of flexibility.
Regular updates will continuously expand the compatibility of your system – for a sustainable, future-proof solution.
Transparency right from the start
Certified power plant characteristics of the controller blue’Log XC and the provision of simulation models as required ensure greater transparency in the grid integration of your PV system. This reduces the risk already in the planning phase.
Grid conformity thus becomes a calculable factor and guarantees you a smooth approval procedure when connecting to the grid.
