Sol-Ark 18k Bundle with Renon Xtreme 20kWh

Sol-Ark 18K Bundle with Renon Xtreme LV 20.48kWh LFP Battery

The Sol-Ark 18K Bundle with Renon Xtreme LV 20.48kWh LFP Battery combines one of the most powerful residential hybrid inverters on the market with a high-capacity modular lithium iron phosphate energy storage system. Designed for whole-home backup, off-grid installations, and advanced solar + storage systems, this integrated solution delivers exceptional power output, scalability, and long-term reliability for modern residential energy systems.

High-Power Hybrid Inverter for Whole-Home Backup

At the core of the system is the Sol-Ark 18K-2P hybrid inverter, engineered to support large residential loads and demanding backup applications. The inverter delivers 18 kW continuous AC output with an industry-leading 36 kW surge capacity, ensuring reliable startup for high-demand appliances such as HVAC compressors, well pumps, EV chargers, and large motors during grid outages. 

The Sol-Ark 18K supports up to 32.4 kW of DC solar input and 19.2 kW of AC-coupled PV, providing exceptional flexibility for both new solar installations and retrofits of existing grid-tied systems. 

 With three MPPTs, installers can optimize string configurations across multiple roof orientations while maximizing system production.

With 200 A grid passthrough capability, the inverter enables true whole-home backup without requiring a critical loads panel. When the grid fails, the system transitions in under 5 milliseconds, maintaining uninterrupted power to connected loads while seamlessly switching to battery and solar generation.

High efficiency is another key advantage, with 97.6% maximum conversion efficiency, ensuring more solar energy is delivered to the home and stored for later use. 

Renon Xtreme LV 20.48kWh Modular Battery Storage

Energy storage in this bundle is provided by the Renon Xtreme LV 20.48kWh battery, a modular low-voltage lithium iron phosphate (LiFePO₄) energy storage system engineered for safety, durability, and flexible expansion.

The system delivers 20.48 kWh of nominal storage capacity and up to 15.4 kW of output power, enabling extended backup duration and strong support for high-demand household loads. 

 Built with advanced LiFePO₄ cell chemistry, the battery provides excellent thermal stability, long cycle life, and enhanced safety compared to traditional lithium battery technologies.

Designed for modern solar energy systems, the Xtreme LV battery supports CAN and RS485 communication, allowing seamless integration with hybrid inverters like the Sol-Ark 18K for optimized charging, discharging, and system monitoring. 

The modular architecture allows the system to scale up to 15 battery stacks, providing installers and homeowners the flexibility to expand storage capacity as energy demands grow. 

 This makes the platform ideal for both residential whole-home backup and small commercial energy storage applications.

Smart Energy Management and Monitoring

The Renon Xtreme LV system includes WiFi connectivity and mobile app monitoring, enabling users to remotely monitor battery performance, energy production, and system status from anywhere. The intelligent battery management system helps optimize solar self-consumption, reduce reliance on the grid, and support peak shaving strategies that lower electricity costs.

Built for Reliability and Long-Term Performance

Both components in this bundle are engineered for demanding energy environments. The Sol-Ark 18K inverter features a rugged IP65 / NEMA 3R enclosure designed for indoor or outdoor installation and includes a standard 10-year warranty. 

The Renon Xtreme LV battery system is also rated IP65, allowing flexible installation in garages, utility rooms, or outdoor protected environments. With an 8000-cycle lifespan and a 10-year warranty, the system is built to provide reliable energy storage for many years of daily operation.
