Sol-Ark 18K-2P-N (Limitless 18K-2P-LV) Inverter

Sol-Ark 18K-2P-N (Limitless 18K-2P-LV) Inverter, Hybrid, DC and/or AC Coupled, Battery/Battery Less, 18kW, 120/240/208VAC, 50/60Hz, 48VDC, 3 MPPT Inputs, 200A Disconnect, AFCI/GFDI, NEMA 3R/IP65

The Sol-Ark 18K-2P-N is designed as a high-end, whole-home hybrid inverter that combines very large power output, exceptional surge capability, and unusually high PV input capacity to support demanding residential or light-commercial energy systems. It delivers 18 kW of continuous output directly from battery storage and up to 36 kVA of surge power for 10 seconds, giving it the muscle to start heavy loads such as HVAC compressors, well pumps, and large motors even during grid outages. It also supports over 40 kW of solar input when using AC-coupled configurations, more than any other residential hybrid inverter, allowing homeowners to build oversized arrays for maximum production and resilience. The unit is engineered for harsh off-grid or backup scenarios, with American-developed firmware, robust protective features, and a 10-year warranty, emphasizing reliability and long-term performance. Its broad MPPT voltage window, high DC input limits, and strong battery throughput make it flexible for system designer.
