BOSS: Modular,
Bi-Directional
DC-DC Optimizer for
Storage Systems

Alencon’s Bi-Directional DC-DC Optimizer for Storage Systems, the BOSS, is a groundbreaking solution for integrating solar and storage using both AC and DC-coupled topologies. The BOSS enables precise, granular control over the charging and discharging of individual battery racks or entire BESS containers through its patented, galvanically isolated design.

What sets the Alencon BOSS apart is its status as the only DC-DC optimizer on the market capable of managing battery charge and discharge at the rack level while providing galvanic isolation. This innovative technology offers system owners and battery integrators key advantages, such as the ability to integrate grounded PV systems with floating batteries and accommodate large voltage differentials between PV arrays and battery storage. Depending on the desired performance of the battery energy storage system, the BOSS can individually charge or discharge each battery rack, ensuring optimal system efficiency.

The BOSS is an ideal, cost-effective solution for both new PV + storage plants and retrofitting storage into existing PV facilities. It also seamlessly supports storage-only applications. To suit diverse project needs, the BOSS offers multiple installation options: units can be mounted directly atop individual battery racks inside a container, housed in a single rack within a battery container, or installed in an outdoor-rated enclosure.

For larger systems, multiple BOSS units can be paralleled within a BOSS BOX. With Alencon's JBOX and PODD, these units can be controlled as coordinated “clusters,” simplifying system management.

Thanks to its unmatched flexibility, the BOSS can be easily and cost-effectively paired with either string or central inverters, offering storage integrators a powerful, adaptable tool for solar and storage solutions.
