Powerpack is a fully integrated, AC-connected energy storage system with everything needed to connect to a building or utility network. It dramatically simplifies installation, integration and future support, offering system-wide benefits that far outweigh those of standalone batteries
Every Powerpack contains 16 individual battery pods, each with an isolated DC-DC converter. Pod architecture and on-board power electronics optimize performance across the array and enable easy swapping at any time.

Powerpacks house the world’s most sophisticated batteries. Each Powerpack is a DC energy storage device containing 16 individual battery pods, a thermal control system and hundreds of sensors that monitor and report on cell level performance.
Grid Interface –
Bi-Directional Inverter -The inverter converts AC grid power to DC for Powerpack storage, then converts this DC power back to AC for grid interconnection.
Powerpack Controller – This onsite computer interface creates control signals and relays commands to the inverter and DC combiner based on integrated application control software, or control signals relayed from a SCADA system.
Software – State of the art battery management software controls performance at the cell, pod and pack level. Built in control software enables dispatch from a locally hosted interface, a direct Modbus/DNP3 connection and scheduled or autonomous operation. No additional software or integration is necessary.
