Sol-Ark Limitless 12K-2P-LL Hybrid Inverter
SKU SOL-ARK-12K-2P-LL-HYB-INV
Limitless 12K-2P-LL Hybrid Inverter
The Sol-Ark Limitless 12K-2P-LL is a compact all-in-one hybrid inverter that delivers 12 kW of 120/240 VAC grid output and 10 kW of continuous backup power from batteries in one of the smallest enclosures in its class. Built for budget-conscious residential projects, it comfortably supports loads such as mini-split A/C systems, well pumps, kitchen appliances, furnace blowers, and lighting without the size of higher-power units.
A 3-MPPT architecture accepts up to 19.2 kW of PV input, while 100 A grid passthrough connects to larger backup load panels without external contactors. With both DC and AC solar coupling, integrated Smart Load control, and generator support through the multifunction GEN port, the 12K-2P-LL fits new installs and retrofits alike and can be deployed on-grid or off-grid.
Sol-Ark Limitless 12K-2P-LL Features
- 12 kW Cost-Effective Backup: 12,000 W of 120/240 VAC grid output and 10,000 W continuous from batteries, with a 24,000 W (10s) off-grid surge for motor-starting loads.
- 3x MPPT Solar Design: Up to 19.2 kW PV across 3 MPPTs (2 strings each) at 32 A per MPPT, sized for modern high-wattage modules with integrated rapid shutdown control.
- 100 A Grid Passthrough: Connects directly to larger backup load panels without external contactors, simplifying whole-home backup wiring.
- DC & AC Coupling: DC-coupled solar plus up to 14 kW of AC coupling makes it ideal for both new installations and retrofit projects.
- 5 ms Backup Transfer: Seamless transfer to battery backup, with a 220 A charger and 48 V battery port supporting lead-acid or lithium-ion banks.
Sol-Ark Smart Energy Management
The Limitless 12K-2P-LL is designed for maximum solar utilization and grid flexibility. Integrated Smart Load control, multi-season Time-of-Use scheduling, peak shaving, and Virtual Power Plant readiness let homeowners lower energy costs while staying prepared for outages. The GEN port adds 2-wire automatic generator start and AC-coupled PV support, and the system is scalable to 12 units in parallel as energy needs grow.
Sol-Ark Limitless 12K-2P-LL Technical Review
The Sol-Ark Limitless 12K-2P-LL is a transformerless hybrid inverter that delivers 12,000 W of continuous 120/240 VAC output (also configurable for 208 V) with a 24,000 W ten-second off-grid surge for starting motors and compressors. Its three independent MPPTs accept up to 19,200 W of PV across two strings each, operate over a 150-425 V MPPT window up to a 500 V maximum input, and carry 32 A per tracker, enough headroom for modern high-wattage modules on real-world residential roofs. On the storage side it drives a 48 V battery bank (43-59 V) at 220 A charge/discharge with both lead-acid and lithium-ion support over CANBus and RS485 MODBUS, while a 100 A grid passthrough and 5 ms transfer time keep critical loads online during outages. With 97.6 % maximum efficiency, an IP65 / NEMA 3R enclosure rated from -40 to 60°C, a 10-year warranty, and listings to UL1741 3rd SB, IEEE1547-2018, and UL1699B PVDC AFCI, it suits space-constrained rooftop, retrofit, and whole-home backup installations.
