Freemaq PCSM / Multi PCSM — battery inverter (PCS) with built-in MV transformer up to 5.36 MVA
Country: Spain · Model: Freemaq PCSM / Multi PCSM
A four-quadrant PCS for grid energy storage systems rated up to 5360 kVA at 30 °C with a direct output of 30, 33 or 34.5 kV. The transformer and MV switchgear are already in the enclosure, so the unit is connected to the line without a separate substation.

Description
The converter works in all four quadrants, that is, it controls active and reactive power in both directions. At 40 °C the rating is 4940 kVA, and for a short time the unit withstands up to 166 % for 100 ms, which helps to ride through load starts and grid disturbances. The MV grid voltage allows a deviation of ±10 %. The battery input is rated for 1019–1500 V, and the battery chemistry can be any, provided the array has its own BMS. The standard PCSM accepts one DC input. The Multi PCSM version has up to 4 independent inputs, so each battery section works through its own channel.
How to choose
The model is chosen by the voltage of the line to which the BESS is connected. For 30, 33 and 34.5 kV grids the PCSM removes the need for a separate transformer station. If the project provides for a low-voltage 690 / 720 V bus and its own substation, the Freemaq PCSK with the same 5360 kVA will be simpler. For a hybrid solar plant where the storage sits on the DC bus of the solar inverter, consider the 1200 kW Freemaq DC/DC converter.

FAQ
What MV voltage is the Freemaq PCSM rated for?
The built-in transformer delivers 30, 33 or 34.5 kV with a tolerance of ±10 %. The inverter is connected directly to the MV distribution grid.
What overload can the PCSM withstand?
Up to 166 % of rated power for 100 ms. This margin is enough for short grid events, but not for a prolonged overload.
What batteries can be connected to the Freemaq PCSM?
The battery type is not restricted, LiFePO4 or other chemistry will do, but the battery must work with a BMS. The DC voltage must be within 1019–1500 V.
How many battery inputs does the Multi PCSM have?
Up to 4 independent DC inputs, whereas the base PCSM has one. This way one converter serves several battery sections.
How does the PCSM power change with temperature?
At 30 °C up to 5360 kVA is available, and at 40 °C 4940 kVA. In a BESS project for a hot climate the second value is used.
