Lithion has completed testing and evaluation to acquire UL 9540 certification for its HomeGrid Stack’d Series (9.6 kWh to 38.4 kWh) energy storage solution combined with the Sol-Ark 12k inverter.

The UL9540 safety certification allows HomeGrid to expand its offering to more customers across North America. HomeGrid products offer a high-capacity, customizable power solution catered to customers through a modular design. The lithium iron phosphate battery comprises Tier 1 prismatic cells, delivering performance guaranteed by a 10-year, 4,000 cycle, non-prorated warranty. The cobalt-free, low-voltage system can be installed within an hour, the company says.

“The modularity of the HomeGrid Stack’d series battery provides a Lego-like form factor, allowing it to match Sol-Ark’s ease of install and all-in-one solar solution, says Bhawna Oberoi, COO of Sol-Ark. “The Stack’d Series battery has an output that can utilize the full capability of our inverters. With our upcoming Sol-Ark 15k, the Stack’d Series battery will be the only battery on the market to maximize its capability.”
