    Sol-Ark 15K-2P + Discover Helios 16kWh Battery | 16kWh Whole-Home Backup Power Bundle

    This residential energy storage system combines Sol-Ark 15K-2P hybrid inverter with a single 16kWh Discover Helios battery. It delivers focused protection for critical loads, including refrigeration, lighting, communication systems, and select appliances without the complexity of larger installations.

    • 4th Generation Battery Management System
    • 5ms Backup Transfer Time
    • Expandable energy storage up to 32kWh

    About the Product

    This hybrid solar inverter system transitions seamlessly between grid-tied, off-grid, and backup modes. The Sol-Ark 15K-2P hybrid inverter switches to battery power within 5 milliseconds—fast enough to keep computers and sensitive electronics running without interruption. For off-grid properties, the system operates continuously without utility connection, managing solar input and battery charging autonomously.

    With three independent MPPT controllers, you can extract maximum energy from solar arrays even when panels face different directions or experience partial shade. This design flexibility makes the bundle compatible with both new solar installations and retrofit applications where existing panels remain in place.

    The 16kWh Discover Helios battery module uses lithium iron phosphate chemistry, offering thermal stability and longevity with 6000+ cycles. The battery features self-heating which activates automatically when temperatures drop, ensuring reliable charging performance down to -13°F without manual intervention or external heating equipment.

    Furthermore, the integrated 4th generation battery management system balances individual cells, monitors operating temperatures, and communicates status directly to the inverter via CAN bus protocol. For added convenience, Wi-Fi and Ethernet connectivity enable remote system monitoring through mobile apps. As a plus, the bundle supports expansion to 32kWh, so you won’t need to replace existing equipment.

    What’s Included in the Sol-Ark-2P 16kWh Whole Backup Power Bundle?

    • Sol-Ark 15K-2P-N Hybrid Inverter (1 pc.)
