ONESUN Single Phase Off-grid High Frequency Inverter (SHH Series) – available in 3.5kW, 6kW, and 11kW – a multi-functional, enhanced PV, industrial-grade integrated energy storage inverter designed to excel in the most demanding environments.

Seamless Power, Anywhere, Anytime

Unpredictable grid outages can cripple operations. The SHH Series delivers seamless on/off-grid switching in milliseconds, so sensitive loads keep running without interruption. Whether you’re in a remote off-grid cabin, a farm, or a small business in an unstable grid area, this inverter guarantees high power reliability. And because it supports electricity selling and metering, you can feed excess energy back to the grid, turning your system into a revenue-generating asset.

Dual Battery Modes – Transform Assets into Income

Energy storage should work for you, not just sit idle. The SHH Series offers dual battery modes – one for self-consumption optimization and another for peak shaving / arbitrage. By charging when electricity is cheap (or solar is abundant) and discharging during peak price periods, you transform your battery bank from a passive cost into an active income stream. This intelligent profit mode is accessible via simple settings, putting financial control in your hands.

Transparent Management, Meticulous Accounting

Knowledge is power. The SHH Series provides transparent power usage management with real-time monitoring of PV generation, battery status, grid import/export, and consumption. Every kWh is meticulously calculated, giving you clear insights to further optimize your energy strategy. Whether you’re an installer managing multiple sites or a homeowner tracking savings, the data is always at your fingertips.

Industrial-Grade Reliability – Worry-Free in Harsh Environments

Built to last, the SHH Series meets industrial-grade standards for temperature extremes, humidity, and dust. Its high-frequency topology ensures compact size and efficiency without compromising durability. From scorching deserts to cold highlands, this inverter performs reliably, year after year.

Three Priority Working Modes – Flexible to Your Needs

Choose between Photovoltaic Priority (maximizing solar use), Battery Priority (storing energy for backup or peak shaving), or AC Priority (relying on grid when most economical). This flexibility adapts to time-of-use tariffs, weather forecasts, or critical load requirements.

The ONESUN SHH Series is more than an inverter – it’s a complete energy management system. It combines PV oversizing, seamless switching, dual profit modes, and industrial toughness into a single, easy-to-install unit. For homeowners seeking energy independence, businesses chasing lower electricity bills, or off-grid pioneers needing absolute reliability, the SHH Series delivers.
