SMARTSYS M5000 medium voltage container BESS from 2.5 MVA / 5 MWh
Country: France · Model: SMARTSYS M5000
A medium voltage container BESS whose base configuration starts from 2.5 MVA / 5 MWh. It is used where the storage unit is connected directly to the MV grid, that is near large PV and wind plants, at substations and at industrial sites with their own medium voltage input.

Description
The storage equipment is housed in a container, so the system arrives at the site in large blocks, and the civil work comes down to a foundation, cable routes and connection. The ratio of 5 MWh to 2.5 MVA corresponds to about two hours of discharge at rated power. This duration is enough to shift daytime PV generation to the evening consumption peak or to work in the ancillary services market. At medium voltage currents are several times lower than at low voltage, so cable lines from the container are thinner and losses in them are lower. For connection, the technical conditions of the distribution system operator and an MV switchgear cell on the site side will be needed.
How to choose
This system is considered when a storage unit from 2.5 MVA must be connected to a medium voltage grid as one ready block. If the project requires gradual expansion from 1 MVA to 9 MVA / 33 MWh, SUNSYS HES XXL is a better fit, whose 1–3 MVA SKID version connects to both low and medium voltage. For sites connected only at low voltage there is SUNSYS HES L at 100–600 kVA and SMARTSYS C260 cabinets of 125 kVA / 261 kWh, which can be combined up to 8 in parallel.

FAQ
What power and capacity does the SMARTSYS M5000 container BESS have?
The base configuration has from 2.5 MVA and 5 MWh. Larger systems based on this block are agreed for a specific project.
For how many hours does the SMARTSYS M5000 deliver rated power?
A reserve of 5 MWh at 2.5 MVA corresponds to about two hours at full power. The exact time depends on the permitted depth of discharge and conversion losses.
How does the SMARTSYS M5000 differ from the SUNSYS HES XXL?
The M5000 is delivered as a medium voltage container from 2.5 MVA / 5 MWh. The HES XXL is assembled from outdoor cabinets in a range from 1 MVA to 9 MVA / 33 MWh, and its SKID version also connects to low voltage.
What data is needed to design a site for the M5000?
For layout you need the container dimensions and weight, cooling type, EMS communication protocol and the connection scheme to the medium voltage switchgear. They are taken from the specification of the specific configuration.
