BESS control & monitoring


Broad & Flexible Functionality

BESS standalone, renewables and conventional generation colocated, or Solar + Storage True Hybrid configuration.

Power and energy oriented services, including frequency regulation, ramp-rate control, as well as time shifting, energy arbitrage, peak shaving and others.

Local and remote control and monitoring compatible with different user objectives: plant operator, grid operator, plant owner, services team, etc.


Grid Connection Robustness

Extensive grid code knowledge based on Wind, Solar and BESS experience in more than 54 countries.

Robust and accurate grid code compliance proven in the most demanding grid codes, including Australia, Europe, Mexico, South Africa, USA, and others.

Fast frequency control, Voltage control as a standard with advanced features, such as Virtual Synchronous Machine (VSM) mode and black start mode as an optional.


Intelligent Battery Management

Virtual Battery Model (VBM) approach to allocate BESS power and capacity to different services.

Smart multi-PCS and multi PV inverter coordination for maximum optimization of the battery usage.

Modular design and full scalability from small to large utility scale projects.
