Description
Sol-Ark 18kW 120/240 VAC 48VDC Indoor/Outdoor Inverter is a high-power hybrid inverter designed for large residential and light commercial energy systems that require flexible operation and high solar input capacity. Built around a 48 V battery architecture, it delivers split-phase 120/240 VAC output while supporting grid-connected, off-grid, and battery-backed configurations.
The inverter is housed in a weather-resistant enclosure suitable for both indoor and outdoor installation and is engineered to operate across wide environmental conditions. Its high PV input capacity and broad MPPT operating range allow for large solar arrays and flexible string design, making it well suited for whole-home backup systems and high-demand applications.
