Sol-Ark 15 kW All-in-One Hybrid Inverter—Resilient Full-Home Backup for the Most Demanding Applications If you need reliable backup power and grid-tie flexibility, Sol-Ark 15kW hybrid inverter lives up to expectations with 19.5kW solar input capacity. Whether protecting against outages or transitioning to energy independence, this hybrid inverter delivers professional performance with scalable architecture. 19.5kW Solar Input Capacity 200A Grid Pass-Through Stackable to 180kW About the Product The Sol-Ark 15kW all-in-one solar inverter delivers 15,000W continuous AC output from solar with support for up to 19,500W of PV input capacity across three independent MPPT trackers with integrated rapid-shutdown controls. Built for seamless backup transitions, the Sol-Ark 15kW features 5ms automatic transfer switching with 200A grid pass-through capability, maintaining power to every circuit during outages. The hybrid design operates in 220V single-phase, 120/240V split-phase, or 120/208V configurations, adapting to grid-interactive, off-grid cabin, or small commercial microgrid applications with equal versatility. Moreover, it supports 48V lithium and lead-acid systems with CAN Bus and RS485 communication protocols for closed-loop battery management. Future expansion requires no hardware replacement. Stack up to 12 units in parallel for 180kW of combined output without replacing existing hardware. With this whole-home backup inverter, you can scale easily, from single-family homes to multi-tenant buildings. The IP65 weatherproof enclosure operates from -13°F to 131°F, while integrated arc-fault detection, ground fault monitoring, and Type II surge protection meet all UL 1741 SB/SA requirements. Wi-Fi and Ethernet connectivity enable VPP enrollment, EV charger integration, and AC-coupled legacy system retrofits on day one.
