description: PowerGrid-INF-01-V3-Brochure for PowerGrid subsystemsIntroduction
We provide two subsystems for grid applications:
- PowerGrid 12000 is built with 2 to 4 units of our 1.6MW / 3MWh BESS container delivering up to 6.4MW and 12MWh per subsystem
- PowerGrid 20000 is built with 2 to 4 units of our 2.58MW / 5MWh BESS container delivering up to 10MW and 20MWh per subsystem. This can be configured as a 2 hour or 3 hour or 4 hour battery storage.
PowerGrid 12000
The PowerGrid 12000 BESS subsystem is built for 6.4MW / 12.3MWh ESS blocks and includes:
- FOUR units of 20C1600K BESS containers each with 8 independent battery strings with dedicated Inverters.
- ONE unit of MV container with a 6600 kVA transformer and LV and MV switchgear and metering. Can be configured for 20kV or 35kV installations.
- ONE set of network switch and subsystem controller for SCADA, PPC and EMS services.
- All power and data cables for the subsystem to the MV container and control cabinet.
- A power output to site substation, a Modbus TCP interface for BESS monitoring and PPC and EMS services for each of the units of 20C1600K BESS containers.
Our reference subsystem is a 6.4MW / 12.3MWh system with 4 BESS containers and a 6600 kVA transformer container. The PowerGrid 12000 is easily scaled down to:
- PowerGrid 9000 with 3 BESS containers with 4.8MW / 9.2MWh capacity.
- PowerGrid 6000 with 2 BESS containers with 3.2MW / 6.1MWh capacity.
PowerGrid 20000
The PowerGrid 20000 BESS subsystem is built for 10MW / 20MWh ESS blocks and includes:
- TWO to FOUR units of 20C2500K BESS containers each with 12 independent battery strings with dedicated Inverters.
- ONE unit of MV container with a 5500kVA or 6600kVA or 10000kVA transformer and LV and MV switchgear and metering. Can be configured for 20/21kV or 33/35kV installations.
- ONE set of network switch and subsystem controller for SCADA, PPC and EMS services.
- All power and data cables for the subsystem to the MV container and control cabinet.
- A power output to site substation, a Modbus TCP interface for BESS monitoring and PPC and EMS services for each of the units of 20C2500K BESS containers and the MV transformer substation.
It can be configured as a 2 hour, 3 hour or 4 hour battery by adjusting the MV transformer sizing and derating the BESS container power via our PPC controller.
