Sol-Ark Limitless 12K-2P-LL Hybrid Inverter
Compact 12 kW hybrid power with 3 MPPTs.
The all-new Sol-Ark Limitless 12K-2P-LL delivers 12 kW-class AC output in one of the smallest hybrid enclosures in its class. A 3-MPPT architecture supports up to 19.2 kW of PV on real-world roofs, 100 A continuous AC passthrough connects larger backup load panels without external contactors, and the GEN port accepts up to 14 kW of generator or AC-coupled input. This is the 12K platform Lumis installs moving forward.
