THE INNOVATIVE MEDIUM VOLTAGE CENTRAL STRING BATTERY INVERTER
UTILITY SCALE MV BATTERY INVERTER
The Power Electronics PCSM medium voltage battery inverter is designed for utility scale storage applications, that require the advantages of a central inverter solution but also the modularity of a string architecture. The PCSM can reach up to a nominal power of 3.6 MVA and it is compatible with all battery technology and manufacturers. It also has the added advantage of having an integrated medium voltage transformer and switchgear.
The MULTI PCSM can support two or three independent battery systems and optimize the storage facility.
Power Electronics converters have been designed to be the lowest LCOE solution in the market for storage applications. The Power Electronics Freemaq PCSM offers proven hardwa-re 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 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 Freemaq PCSM stations are turn-key solutions ready for connection to the battery contai-ner and MV power distribution wiring. Units are designed for concrete pads or piers.

REAL TURN-KEY SOLUTION - EASY TO SERVICE
With the PCSM, Power Electronics offers a real turn-key solution, including the MV transformer and switchgear fully assembled and tested at the factory. The PCSM is a compact turn-key solution that will reduce site design, installation and connection costs, and therefore will minimize the LCOE.
By providing full front access the PCSM series simplifies the maintenance tasks, reducing the MTTR (and achieving a lower OPEX). The total access allows a fast swap of the FRUs without the need of qualified technical personnel.

ACTIVE HEATING
When the unit is not actively exporting/importing power, the inverter can import a small amount of power to keep the inverter internal ambient temperature above -20°C, without using external resistors.
This autonomous heating system is the most efficient and homogeneous way to prevent condensation, increasing the inverters availability and reducing the maintenance. PATENTED
INNOVATIVE COOLING SYSTEM
Based on more than 3 years of experience with our MV Variable Speed Drive, the iCOOL3 system allows to get NEMA 3R degree of protection in an outdoor converter. iCOOL3 delivers a constant stream of clean air to the FRUs, being the most effective way of reaching up to NEMA 3R degree of protection, without having to maintain cumber-
some dust filters or having to use liquid-cooling systems, avoiding the commonly known inconveniences of it (complex maintenance, risk of leaks, higher number of components…), therefore resulting in an OPEX cost reduction and a LCOE improvement.

ENERGY STORAGE APPLICATIONS
Freemaq PCSM series are able to store energy during periods of low demand from the grid, in order to later supply this energy when there is a higher demand. This has the bene-fit of selling the energy at a higher market price during peak periods. It also allows grid operators to supply electricity with a higher renewable origin. Since PV generation may not be at the same time as peak demand, this facilitates the flexibility and integration of renewable generation into the grid.
The Freemaq PCSM series attenuates the intermittent nature of renewable energy sources, to provide a smoother power output. The Freemaq PCSM controls the ramp rate at which power is injected into the grid, and thus reduces the impact of rapid power fluctuations due to sudden or transient conditions experienced by the PV array. The system monitors the PV inverter output to inject or consume power accordingly to ensure the output remains within the ramp requirements.
LOAD LEVELING
RENEWABLE INTEGRATION
PEAK POWER SHAVING
By delivering stored energy to the grid during periods of high demand, it reduces the burden on the distribution network and increases significantly its efficiency. Energy is stored instead of injected into the grid during periods of low demand, which as a result increases the load on the grid. However, during peak periods this stored energy is then injected into the grid, which reduces the demand at this time. The result is a more flattened demand curve which means the grid can avoid switching on more expensive and polluting generators.

Freemaq PCSM series helps the integration of renewable sources, by helping to maintain grid stability and power quality. It can help support the grid voltage by generating capacitive or inductive current.Other features include Voltage Control, Reactive Power Control and Fault Ride Through Support.
GRID SUPPORT
FREQUENCY REGULATION SYSTEM
Freemaq PCSM provides ability to regulate grid frequency in both directions. When there is a grid overfrequency (generation>demand) inverter power output is curtailed and this energy is stored through charging batteries. When there is a grid under-frequency (generation<demand) inverter power output is increased by discharging the batteries and injecting more power to the grid.
