VARTA Microbattery announced that the safe and reliable Engion Series is designed to allow residential and commercial property owners greater independence from public utilities by reducing their cost of electricity and ensuring power is available in the event of a power grid fault. Comprised of Engion Home and Engion Family systems, the series employs VARTA's highly efficient lithium ion (li-ion) battery modules to store energy generated by photovoltaic (PV) systems and/or the electric utility grid.  Due to the modular configuration of the VARTA battery modules, systems may be configured with capacities ranging from 2.8 kWh to 13.8 kWh and are available in the range of 25 kW through 100 W. The systems additionally feature a battery inverter capacity of up to 4.0 kW.

VARTA Storage's Engion Home systems are provided with capacities of from 2.8 kWh to 6.9 kWh and a battery inverter capacity of up to 2.4 kW, whereas Engion Family systems are offered with capacities of from 3.7 kWh to 13.8 kWh and with a battery inverter capacity of up to 4 kW. The series supports 3-phase 400 VAC input along with an Ethernet interface.  It also boasts an expected life of up to 8,000 cycles and a 20-year lifespan.   Engion Family systems measure 60 cm (W) x 185 cm (H) x 40 cm (D), while Engion Home systems measure 60 cm (W) x 130 cm (H) x 40 cm (D).  The series is engineered with extensive redundant mechanical and electrical functions, flame-retardant housing and automatic overvoltage cutoff.
