Sol-Ark 15K 120/240/208V-3R Hybrid All-In-One Stackable Solar Inverter

15K 120/240/208V-3R Hybrid All-In-One Stackable Solar Inverter

The Sol-Ark 15K Outdoor Case Inverter introduces a wider range of capabilities compared to its Sol-Ark 12K counterpart. This all-in-one, pre-wired inverter system is packed with new features, offering unmatched efficiency and cost-effectiveness in its class.

Sol-Ark 15K Overview

Limitless Functionality
Operates both on-grid and off-grid, with versatile applications including parallel stacking, grid sell, meter zero, time-of-use optimization, smart load management, AC coupling, and peak shaving.

All-In-One Design
The Sol-Ark 15K comes pre-wired with an inverter, charge controller, and essential components in a single unit—eliminating the need for extra fuses, breakers, or combiner boxes. This keeps installations simple and affordable.

Battery Agnostic
Unlike many solar inverters with costly battery limitations, the Sol-Ark 15K supports a wide range of 48V battery chemistries, from lead-acid to lithium.

Built to Last
Undergoes Highly Accelerated Life Testing, ensuring reliability well beyond its standard 10-year warranty.

Made & Supported in the USA
Engineered, tested, and serviced in the U.S., with access to U.S.-based engineers available 7 days a week.

Best Applications

The Sol-Ark 15K is ideal for off-grid setups, large-scale energy gains, and time-of-use savings. For smaller projects, the Sol-Ark 12K is recommended.

• Grid-Tied Mode: Sell excess power back to the utility and lower your electric bill.
• Meter Zero Mode: Offset your bill entirely without needing an additional smart meter.
• Time-of-Use Mode: Rely on solar and batteries during peak pricing periods to cut costs.
• Smart Load Mode: Power high-demand off-grid or time-of-use loads with programmed output.
• Off-Grid Applications: Fully battery agnostic for flexible energy storage solutions.
• AC Coupling: Upgrade existing grid-tied systems with ease.
• Battery Backup: Keep essential loads powered during outages.
