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.
BMS firmware and hardware have been updated to allow V2 and V3 versions to be used with V4, if expansion is needed.
Wireless on-site detailed battery status monitoring
Integrated HAB to Inverter Modbus communications w RJ45 on both ends of cable using the RS-485 standard. Integrated HAB to HAB CAN bus communications w RJ45 on both ends of cable.
≤3% per month *Only achieved if HAB is put to sleep by pressing down the power button for 10 seconds, otherwise standard shutdown can cause self-discharge to be as high as 9% per month
14 batteries in parallel
All versions of HABs can communicate with each other, as long as they are updated with the latest firmware versions. (*V1 updates can not be done over internet so please call in to have special update kit sent). Conditions: When adding in parallel configuration to an older bank, the newest HAB version must be the leader. Communication cable is required.

*IMPORTANT NOTE: SOL-ARK 12K is a combined output - (split between DC Battery and AC Loads/Grid). The max power to the grid or AC loads is 9kW - in conjunction with simultaneously charging the batteries. So for example - if 9kW is going to the grid, an additional 3kW of power can be used to charge the batteries.
