Li-ion battery system boasts a life expectancy of 12,000 charge cycles

VARTA Storage will introduce the system at Solar Power International, held from 14^th to 17^th September 2015 at the Anaheim Convention Center, Anaheim, CA.  Additionally on exhibit will be the Engion Sentry energy storage system for residential and commercial back-up applications. VARTA Storage products may be remotely controlled and monitored from a smartphone or the internet.  

Offered for use in an array of solar power systems, the VARTA Flex Systemis fully compatible with standard 480V, three-phase AC inverters. It is suited for demand response programs enabling commercial end-use electric customers to reduce their electricity usage in a given time period, or shift that usage to another time period in response to a price signal, a financial incentive, an environmental condition or a reliability signal. 

The VARTA Flex System provides reliable emergency standby non-critical power while ensuring customers are able to minimise and manage their electricity costs through the peek shaving process, and participate in electricity arbitrage systems.

The VARTA Flex System is supplied in a ventilated enclosure and may be ordered with battery racks providing from 24 to 1000kWh.  This facilitates their use in stationary storage applications requiring output power from 30 to 1000kW. 

"The VARTA Flex System is specially engineered for commercial applications including demand response participation programmes, and is a significant addition to VARTA's growing portfolio of solar energy storage solutions for the commercial and residential markets," commented William Flanagan, President and CEO, VARTA Microbattery.

"We have long recognised the precise requirements of commercial meter customers seeking a robust and reliable system that allows cost-effective participation in electric utility demand response programmes, as well as ensuring power is available 24/7.  We are very excited to deliver this total Li-ion battery and battery management system solution which will operate continuously for many, many years."
