Sol-Ark 15K-2P + (2) Discover Helios 16kWh Batteries | 32kWh Whole-Home Backup Power Bundle
The Sol-Ark 15K-2P 32kWh bundle pairs a high-capacity hybrid solar inverter with robust lithium energy storage to deliver a flexible and dependable power solution for homes. Designed to support backup power, solar self-consumption, or full off-grid operation, this expandable system offers commercial-level capability while remaining straightforward to install in residential settings.
At the core of the system is the Sol-Ark 15K-2P hybrid inverter, providing 15kW of continuous power and working in tandem with two Discover Helios 16kWh LiFePO4 battery modules for a total of 32kWh of usable storage. This configuration is capable of running essential and high-demand household loads—such as heating and cooling equipment, well pumps, kitchen appliances, and EV charging—when utility power is unavailable.
The inverter incorporates three independent MPPT channels to maximize solar production across complex or partially shaded arrays. Its hybrid design allows seamless operation across grid-tied, backup, and off-grid modes, switching in as little as 5 milliseconds while intelligently managing loads to extend runtime during outages. Support for up to 19.2kW of AC-coupled solar input also makes it well suited for homes with existing solar systems.
Energy storage is handled by two Discover Helios lithium iron phosphate batteries, each delivering 16kWh and equipped with a fourth-generation battery management system that continuously monitors operating conditions for safety and longevity. Both the inverter and batteries are rated for indoor or outdoor installation, with IP65 enclosures providing protection against weather, dust, and temperature fluctuations. Integrated battery heating allows reliable performance in cold climates down to -13°F, while CAN bus communication ensures tight system integration. Remote system access is available through Wi-Fi and Ethernet connectivity, enabling monitoring and control via mobile and web-based platforms.
