Sol-Ark > Limitless 18K Hybrid Inverter
The Most Powerful Residential Hybrid Inverter on the Market.
Residential Hybrid Inverter:
Limitless 18K-2P-LV
SKU: Limitless 18K-2P-N
The Sol-Ark 18K-2P-N is a more powerful, rugged, and compliant model. It allows much larger PV arrays, higher surge handling (ideal for motors/AC units), stronger battery throughput, and broader environmental ratings.
Powerful. Intelligent. Reliable.
Engineered for the most grueling off-grid or backup needs, the 18k 2P-N can deliver industry leading continuous power from batteries to support large loads. The 18k 2P-N delivers 36kW of surge power for 10s to ensure HVAC units and motors have no problem starting in a grid-down scenario. In order to ensure adequate production, the 18k 2P-N supports more PV than any other residential inverter (over 40kW when utilizing AC coupled functionality). This powerhouse unit runs American engineered firmware, keeps your data stateside, and comes standard with a 10-year warranty.
Don’t rely on the grid, take control of your energy.
The Ultimate in Home Back Up Power
Rising electricity costs, greater grid instability, and growing consumer demand for resilient home energy solutions are reshaping how homeowners evaluate solar energy systems.
The Sol-Ark® 18K-2P (18K-2P-N) hybrid inverter stands at the forefront of this market transformation.
Engineered for the most grueling off-grid or back-up needs, the 18K-2P delivers
up to 18kW of continuous power directly from battery storage to support large loads and 36kVA of surge power for 10s to ensure demanding loads like HVAC units and motors have no problem starting in a grid-down scenario.
The 18K 2P supports more PV than any other residential inverter (over 40kW when utilizing AC coupled functionality). This power-house unit runs American engineered firmware, keeps your data stateside, and comes standard with a 10 year warranty. Don’t rely on the grid, take control of your energy.

All Hybrid Inverter PV Systems will need rapid shutdown. The IMO BG10P34-11 remote shutdown button is an outdoor initiation switch that can be used to trigger PV system rapid shutdown.
IMO RSD Button BG10P34-11 > Rapid Shutdown Button compatible with APsmart Rapid Shutdown System
IEEE 1547-2018 requires the local communications interface to remain available whenever the DER is operating. This indirectly creates a requirement for the IQ Gateway not to reboot during and following a low voltage ride through event. The IQ Gateway hardware was redesigned to meet this requirement so installers must only choose from the list of supported hardware and be running software versions 7.3.460 or later to be fully compliant.
