Sunpal bidirectional state-of-the-art converters use 3-level NPC topology to enable low loss operation, high DC voltage and the best power quality performance thanks to optimized switching frequency.
DC voltage is available with a wide range spanning 600 - 4000Vdc. Bidirectional modules in various sizes are available starting from 50kVA up to 2000kVA, enabling the most cost-efficient solution for each customer-specific project up to hundreds of MWh, or even larger scales.
With Sunpal ESS, energy is available in real time when primary power sources have been interrupted. The solution provides benefits for the entire power system, from generation, transmission and distribution to micro grid operators, all the way to end consumers.
Energy Storage System (BESS) containers are designed for community, public buildings, medium and large enterprise and utility scale storage systems, weak or off grid, power mobility or backup systems. Our Containerized Energy Storage System (BESS) is the perfect solution for large energy storage projects. Energy storage containers can integrate various energy storage technologies for different purposes.
The battery energy system consists of battery modules connected in series to meet the required direct voltage level, typically 600-1500Vdc. The racks are connected in parallel to meet the needed energy capacity. One group
of series-connected battery modules form the storage rack. Each rack can have its own battery management system (rack BMS) to manage the state of charge (SOC), state of health (SOH), voltage, current and temperature
of each level of battery modules in the rack, as well as the control and protection.
Sunpal MCC controller measures system voltages and currents and calculates the required PCS current based on measurements, active operation modes and battery status. It transmits reference current to PCS modules via a fiber optic link enabling real time ESS output control. Sunpal MCC controller uses modern compatible communication systems to send and receive status and operation mode settings with higher level operators such as a transmission system operator (TSO).
Sunpal MCC provides energy management for alternative alternative sources including solar, wind and fossil fuel power plants. On-line monitoring and maintenance are available via an internet service provider.
The Sunpal ESS, built on state-of-the-art technology, is a fully scalable modular solution, in terms of output power and energy, for any voltage level of the grid. The latest high efficiency bidirectional converter technology together with continuously developing storage media, selected specifically for the customer’s needs, ensure efficiency and a long lifetime of the storage solution. Sunpal MCC - control, protection, monitoring and SCADA system manage the entire storage, along with energy management and optimization of renewables and all communication with higher level operators.
