About the Product
The Sol-Ark 12kW hybrid inverter combines 9,000W continuous AC output with support for up to 13,000W of solar input across two independent MPPT trackers. Unlike traditional grid-tie inverters requiring expensive service panel modifications, this hybrid inverter features 63A grid pass-through capability that integrates seamlessly into existing electrical infrastructure.
Designed for NEM 3.0 compliance and time-of-use optimization, the 12K-2P stores solar energy when rates peak and exports excess production when utility credits maximize returns. The 48V battery interface with 185A charge/discharge capacity supports both lead-acid and lithium iron phosphate batteries.
The 4ms automatic transfer switching maintains power to critical loads during grid failures, while 16kVA surge capacity handles well pumps, air conditioners, and motor-driven equipment. The IP65 / NEMA 3R weatherproof enclosure operates from -13°F to 131°F with natural convection cooling. Furthermore, with built-in Wi-Fi and Ethernet connectivity, the inverter enables remote monitoring and VPP enrollment for demand-response programs.
