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.
