Atlas ESS powers large loads over a long service life for off-grid and grid tied applications.
Atlas ESS provides the best performance and highest quality at the lowest cost.
Atlas ESS products are made with the highest quality components. All components have been safety tested and listed by a Nationally Recognized Test Lab (NRTL).
We use safe, high quality, large capacity, lithium iron phosphate cells that have passed tough UN38.3 safety tests.
Our Stationary Battery cabinets are fire rated by a Nationally Recognized Test Lab (NRTL). The cabinet protects the lithium cells from a fire outside the cabinet. The cabinet door has 3 large steel dead bolts, a key operated lock and an additional padlock hasp. The cabinet is constructed with multiple layers of 14 gauge steel and a tough powder coat finish.
Tough industrial controls run our energy storage system providing exceptional reliability. Auxiliary relay outputs are available to control other equipment in your power system. Our Battery Management System (BMS) is tested to UL 508, recognized and listed by a Nationally Recognized Test Lab (NRTL).
