The Freemaq PCSK is a modular solution from 1700 kW 3 LEVEL TOPOLOGY to 3800 kW with configurable DC and AC voltages making it compatible with all battery technology and manufacturers. Power Electronics is a proven partner in the solar and energy NEMA 3R / IP55 storage market. The PCSK has been designed to be the lowest LCOE solution in the market for storage applications. The Power Electronics Freemaq PCSK offers proven hardware to meet storage and grid support challenges.The energy production industry is embracing renewable energy sources. However, high penetration creates power transmission instability challenges, thus Grid Operators require stringent dynamic and static grid support features for solar inverters and Power Conversion Systems (PCS). The MULTI PCSK can support two or three independent battery systems and optimize the storage facility. The converters can perform grid support functions such as: Peak Shaving, Ramp Rate Control, Frequency Regulation, Load Leveling and Voltage Regulation, controlled by a Power Plant Controller or SCADA. The converters stations are turn- key solutions ready for connection to the battery container and MV power distribution wiring. Units are designed for concrete pads or piers, open skids or integrated into full container solutions. POWER ELECTRONICS

COMPACT DESIGN - EASY TO SERVICE

By providing full front access the Freemaq PCSK series With the Freemaq PCSK, Power Electronics offers its most simplifies the maintenance tasks, reducing the MTTR (and compact solution, achieving 3.8MW in just 12ft long, reducing achieving a lower OPEX). The total access allows a fast swap installation costs and labor time, and therefore will minimize of the FRUs without the need of qualified technical personnel. the LCOE.

STRING CONCEPT POWER STAGES

The Freemaq PCSK combines the advantages of a central inverter with the modularity of the string inverters. Its power stages are designed to be easily replaceable on the field without the need of advanced technical service personnel, providing a safe, reliable and fast Plug&Play assembly system. Following the modular philosophy of the Freemaq series, the unit is composed of 6 FRUs (field replaceable units). FREEMAQ PCSK & MULTI PCSK 47

INNOVATIVE COOLING SYSTEM

Based on more than 3 years of experience with our MV without having to maintain cumbersome dust filters or having Variable Speed Drive, the iCOOL3 system allows to get IP55 to use liquid-cooling systems, avoiding the commonly known degree of protection in an outdoor converter. iCOOL3 delivers inconveniences of it (complex maintenance, risk of leaks, a constant stream of clean air to the FRUs, being the most higher number of components…), therefore resulting in an effective way of reaching up to IP55 degree of protection, OPEX cost reduction and a LCOE improvement.

ACTIVE HEATING

When the unit is not actively exporting/importing power, This autonomous heating system is the most efficient and the inverter can import a small amount of power to keep the homogeneous way to prevent condensation, increasing the inverter internal ambient temperature above -20°C, without inverters availability and reducing the maintenance. PATENTED using external resistors. POWER ELECTRONICS

MULTILEVEL TOPOLOGY

The multilevel IGBT topology is the most efficient approach Freemaq PCSK design is the result of our experience with to manage high DC link voltages and makes the difference 3 level topologies. The 3 level IGBT topology reduces stage in the 1500 Vdc design. Power Electronics has many years losses, increases inverter efficiency and minimizes total of power design in both inverters and MV drives and the harmonic distortion. High efficiency to deliver the lowest LCOE.
