Sol-Ark 18K-2P-N All-In-One Hybrid Solar Inverter
Engineered for demanding off-grid, grid-interactive, and backup power applications, the Limitless 18K-2P-LV delivers industry-leading 18 kW continuous power from batteries to support large residential loads with confidence. With a 36 kW surge rating for 10 seconds, the system easily starts HVAC systems, pumps, compressors, and other high-inrush equipment during grid outages.
Designed for maximum solar utilization, the 18K-2P-LV supports up to 32.4 kW of PV input and 28.8 kW usable solar, with the ability to accept 28.8 kW of AC-coupled input—making it one of the highest-capacity residential hybrid inverters in its class. Three MPPT channels with high current handling enable flexible string design and optimal harvest across complex roof layouts.
Running North-American engineered firmware with data residency maintained within the U.S., the Limitless 18K-2P-LV is built for reliability, compliance, and long-term ownership, backed by a standard 10-year warranty.
