Description

The Sol-Ark 18K 2P-N is the most powerful residential hybrid inverter available, engineered for demanding off-grid and backup applications requiring uncompromising continuous power and massive surge capacity.

Key Features

  • 18,000W Continuous Output with 36kW Surge: Delivers industry-leading sustained power with enough 10-second surge capacity to start HVAC systems and heavy motor loads without hesitation.
  • MAXPV — Over 40kW Solar Support: Supports up to 28,800W of direct PV input plus 19,200W via AC coupling, allowing larger arrays than any other residential inverter in its class.
  • 3 Independent MPPT Trackers: Three dedicated charge controllers with a 150–425V operating range maximize harvest across complex or shaded array configurations.
  • DATALOCK American-Engineered Firmware: All data transmission is processed domestically, keeping your system data stateside with no foreign server dependency.
  • Stackable Up to 12 Units: Units can be paralleled for scalable three-phase or high-capacity systems, supporting up to 216kW of combined continuous output.

Housed in an IP65/NEMA 3R rated enclosure, the Sol-Ark 18K 2P-N is built for outdoor installation and operates reliably across ambient temperatures from -40°C to +60°C. Wi-Fi and LAN hardware are included standard, with CANBus and RS485 MODBUS communication ensuring seamless BMS integration with leading battery systems.

Backed by a 10-year warranty and certified to UL1741 3rd SB, UL1741 CRD-PCS, IEEE1547-2018, UL1699B PVDC AFCI, and CSA C22.2 No. 107, the Sol-Ark 18K 2P-N is a code-compliant, utility-grade solution for installers and integrators building serious energy independence systems.
