KiloVault® HAB™/Sol-Ark 12K Inverter
UL9540 Energy Storage System

Two robust brands in energy storage come together for a UL9540 certified Energy Storage System.  This means that for states and jurisdictions that require this certification, rigorous thermal and electrical testing was performed.  Evaluation of the UL listed components, together as a system, ensures they are integrated into a safe, high-performance system.  This is a new safety standard for an Energy Storage System (ESS), where the equipment in the system is intended for connection to a local utility grid or standalone application. It designates key safety issues associated with an ESS including: safety of the battery component, fire detection and suppression, and potential environmental hazards. 

A UL9540 ESS is comprised of a UL 1973-certified battery pack(s) and a UL 1741-certified inverter(s), in specific configurations.  Combined system configurations for the KiloVault HAB, certified to UL9540 for residential applications, offer scalable solutions up to 15kWh of capacity. This kit is for 2:1 HAB to Inverter setup.  The other residential certifications are for 1:1 and 2:2.  Non-residential configurations include 3/4/5/6 HABs to 2 Inverters.  Please speak to one of our sales representatives to adjust order based on your application.
