Flexible indoor storage for commercial energy
The Sol-Ark L3 Series HV Energy Storage System delivers scalable high-voltage energy storage for dedicated indoor battery rooms, with configurations designed to support both 208V and 480V commercial energy systems. Built on Lithium Iron Phosphate (LFP) chemistry, the L3 HV family gives system designers a flexible platform for backup power, peak demand management, time-of-use optimization, and greater use of onsite solar.
Choose the HV-40 for Limitless 30K applications or the HV-60 for Limitless 60K applications, with integrated battery management helping bring storage and power conversion together as one coordinated commercial energy system.
Scale storage around your project
Start with the capacity your project requires and expand as your facility, load profile, or runtime needs evolve. Both L3 HV configurations support up to 16 battery units per compatible hybrid inverter, providing up to 655 kWh with the HV-40 or 983 kWh with the HV-60. That gives system designers greater flexibility to size storage around application requirements today while preserving room for future expansion.

Designed for dedicated indoor battery rooms
The L3 HV family is purpose-built for commercial indoor energy storage installations. Its IP20 (NEMA 1) open-rack design provides straightforward access for installation and service within dedicated battery rooms, while forklift and overhead lifting provisions help simplify equipment handling on site.
Paired with compatible Sol-Ark commercial hybrid inverters, the L3 HV provides a coordinated storage platform designed to support efficient installation, commissioning, and long-term system operation.
Built for safety. Designed for confidence.
The L3 HV family uses Lithium Iron Phosphate (LFP) chemistry, valued for its thermal stability and suitability for stationary energy storage applications. Integrated battery management continuously monitors system conditions to help support safe, reliable operation throughout the life of the system. L3 Series battery systems are also supported by rigorous safety certification and testing, including UL 1973, UL 9540, UL 9540A, and UN 38.3 requirements, providing added assurance for system designers, installers, and facility owners.
From storage to a complete energy system
Pair L3 HV energy storage with Sol-Ark commercial hybrid inverters and MySolArk monitoring to create a more coordinated commercial energy system. Bringing your battery, inverter, monitoring, and energy management together within one ecosystem helps simplify system design and commissioning while improving visibility, control, and long-term operation across your facility.
