Sol-Ark SA-18K-2P 18kW Hybrid Inverter

The Sol-Ark 18kW Hybrid Inverter represents the pinnacle of Sol-Ark's residential and commercial energy solutions, delivering an impressive 18,000 watts of continuous split-phase AC output at 120/240VAC from a 48VDC battery bank. Designed for properties with substantial power demands, this all-in-one inverter integrates solar charge control, battery management, and grid-tie functionality into a single, installer-friendly unit. Its NEMA-3R-rated enclosure offers rugged protection against rain, sleet, and windblown debris, making it equally suited for climate-controlled utility rooms or exposed exterior mounting in challenging environments.

A key advantage of this model is its integrated 200-amp AC pass-through, enabling full-capacity utility or generator power to flow directly to the load panel independent of inverter conversion — a critical feature for large estates, commercial buildings, and facilities running high-draw equipment such as EV chargers, central HVAC systems, industrial machinery, and electric water heaters. Sol-Ark's proven architecture ensures seamless switching between grid, solar, and battery sources, protecting sensitive loads while maximizing self-consumption and energy savings. Advanced app-based monitoring keeps operators informed with real-time data and system diagnostics from any location.

Key Features

• 18,000W continuous split-phase output for large residential and commercial applications
• 200A AC pass-through handles high-draw appliances without inverter capacity constraints
• NEMA-3R weatherproof enclosure supports flexible indoor and outdoor installation
• Compatible with LiFePO₄, lead-acid, and other 48V battery storage systems
• App-based remote monitoring provides real-time performance data and system alerts

Applications

The Sol-Ark 18kW is engineered for large, whole-home solar-plus-storage systems, luxury estates, small to mid-sized commercial facilities, agricultural operations, and energy-intensive properties that integrate EV charging infrastructure. Its 200A pass-through and high-output split-phase capability make it the go-to choice where neither power capacity nor reliability can be compromised. Whether serving as a grid-tied backup system for a large family home, a fully off-grid power hub for a remote facility, or a hybrid self-consumption platform for a commercial operation looking to reduce utility costs, the Sol-Ark 18kW delivers unmatched performance, durability, and scalability to meet the most demanding energy requirements.
