PRESS RELEASE – Fortress Power teams up with Sol-Ark to release a new Integrated Plug & Play Energy Storage Solution

Fortress Power All-In-One Battery Storage Solution

SOUTHAMPTON, PA – Fortress Power teams up with Sol-Ark to announce the release of their new integrate energy storage solution.

Consisting of 4 eFlex batteries and a Sol-Ark 12K or 15K inverter, the new all-in-one solution offers peak shaving for demand charge management, load shifting for time-of-use savings, and standalone operation in off-grid mode for power backup as well as storage of excess solar energy.

This new all-in-one solution is IP65 water and dustproof for indoor and outdoor installations. Included are active cooling fans for hot climates and an easy to add din rail thermostat for cold climates. The built-in busbars and cables help make installations 45min or less.

With a built-in 200A grid passthrough, customers can have a whole home backup system without building a separate backup load panel.

The system is UL 9540 certified and meets the UL 9540 (A) large fire test standard. Furthermore, it allows customers flexibility to size up inverter and battery capacity based on their needs and budget.

“The partnership began in 2018. Since then, we have established closed-loop communication with Fortress batteries for maximum system efficiency and battery lifespan.

“We enjoy working with Fortress Power, because they engineer and manufacture safe and high-quality Lithium Iron batteries that work very well with our powerful inverters,” said Tom Brennan, CEO of Sol-Ark.

“We have tens of thousands of batteries installed with Sol-Ark inverters across the U.S., Canada, Central Caribbean, and South America. Customers are very happy with the performance of our systems,” added Jing Yu, the CEO of Fortress Power.

“Sol-Ark is leading the battery-based inverters by offering the largest battery-based inverter. Together we offer our customers high quality, large capacity, plug and play energy storage solutions.”
