Gen I System: Adara Power 8.6 kWh Energy Storage System

In 2013, Adara Power introduced its first Adara Energy Storage System, an 8.6 kWh lithium-ion energy storage system for residential and small scale commercial buildings. With our system controller, the Adara Energy Storage System is integrated with a full-featured commercially available inverter/charger and can be deployed in parallel for higher power and energy needs. The system is designed to support grid-tied, grid isolated in the event of grid failure, and off-grid configurations. Each configuration delivers years of dedicated peak shifting, back-up power, energy efficiency and enables participation in emerging transactive energy exchanges.

An Adara Energy Storage System contains an array of lithium-ion batteries with a battery management system for safe, reliable, long lasting control of the lithium-ion cells. It also contains a system controller to manage the inverter/charger interface to ensure control of charge and has redundant protection mechanisms to prevent over voltage, over current, under voltage and over temperature conditions. A cellular gateway to a secure cloud-based repository enables remote monitoring, updates and control. The Adara Energy Storage System is housed in an indoor/outdoor UL-rated enclosure.

  • Intelligent Controls: The challenge in deploying lithium-ion batteries in small scale commercial and residential buildings is to ensure safety, reliability, long life and interoperability with the solar inverter. The Adara Power controller is the brains of the system. It constantly monitors the state of the battery, the PV output and building load from the inverter and determines the mode of operation based on customer bill rates and other priorities. There is a balance between rates of charge and discharge, operating temperature, depth of discharge and number of cycles that must be achieved to ensure long life. Adara Power’s lithium-ion battery system will last over 10 years in operation. The integration and controls requires deep knowledge of the chemistry of the battery cells and a complete understanding of the end-usage. Adara tunes its control system for external conditions and usage requirements without any compromise on safety and long term reliability.
  • Why Lithium-ion? The battery chemistry selected by Adara Power is a lithium-ion Nickel Manganese Cobalt (NMC). The chemistry is known for long life, high energy density and safety. NMC is the leading automotive cell chemistry. While it is capable of high rates of discharge, Adara Power controls the discharge and charge current depending on the cell temperatures and other conditions to ensure long life. Lithium-ion NMC is 4X the energy density of lead acid batteries, can be recycled or discarded in landfills, lasts 3X longer than lead acid batteries, and requires no maintenance of venting of gases.
  • Adara Power Cloud: All Adara Energy Storage Systems are connected to the Cloud through a robust and secure cellular connection. There are no fire walls or router issues to deal with for installers and homeowners. The data is securely managed and used to provide the homeowner with status, reporting and control via our mobile app. The connectivity allows Adara Power to roll out firmware updates and provide monitoring services for customers.
