About the 21.1kW Complete Solar Kit - Sol-Ark 18K Inverter - 28-40kWh Lithium Battery [ELITE PRO]

Formerly known as the HPK-PRO, the newly branded ELITE PRO is the top of our ELITE line, featuring the Sol-Ark 18K Hybrid Inverter. This system is designed for those who need massive throughput and total energy security. With a nearly 20,000W solar array and a massive battery bank, the ELITE-PRO is a perfect option for power hungry homes, large off-grid set-ups or even light commercial operations.

ELITE Power Kits come with all the parts and pieces you need to get up and running. Engineered for a DIY-friendly experience, they are designed so that a homeowner can comfortably handle the majority of the installation, while remaining simple enough for a local professional to step in and finalize the connection quickly.

Typical Uses: What Can It Run?

Whole-Home Autonomy: Effortlessly manages high-demand loads, including multiple central AC units, EV fast chargers, well pumps, and electric pool heaters simultaneously.

Massive Surge Capacity: With 18,000W of continuous power and a 36,000W surge capacity, this system easily handles the startup of industrial-sized motors and heavy compressors.

Advanced Peak Shaving: Reduce utility costs on a massive scale by shifting your entire home or business to battery power during the most expensive peak-rate hours.

Multi-Day Energy Security: Provides the massive battery reservoir needed to sustain a large property through extended grid outages or long stretches of cloudy weather.

Light Commercial & Agriculture: Ideal protection for warehouses, medical clinics, or modern farms that require zero-downtime, utility-grade power reliability.
