Sol-Ark 30K-3P-208V Commercial Hybrid Inverter

The Sol-Ark 30K-3P-208V is a powerful, flexible, and scalable commercial hybrid inverter designed specifically for light commercial and industrial applications. With built-in AC and DC coupling, native 120/208V three-phase output, and advanced energy management features, it simplifies solar-plus-storage installations while helping businesses reduce demand charges, improve resiliency, and meet sustainability goals.

This inverter supports seamless integration with both existing grid-tied solar PV systems and new arrays, eliminating the need for bulky step-down transformers in most light commercial buildings. Its modular architecture allows systems to scale from 30kW up to 300kW by paralleling up to 10 inverters, making it ideal for growing energy demands.

During grid outages, the system provides fast and reliable backup power with adjustable 20ms transfer time and up to 200A grid pass-through capability, ensuring business continuity for critical loads. With MySol-Ark monitoring, users can remotely monitor, commission, and manage energy usage, battery health, and system performance in real time.

Designed for durability and ease of installation, the unit is outdoor-rated (NEMA 3R), includes integrated safety protections, and comes with a standard 10-year warranty.
