The All-in-One Off-Grid Standard.
3.6kW UL1741 Certified Solar Inverter
Upgrade your off-grid energy system with the RUiXU SUNON3.6. This next-generation 3.6kW inverter is more than just a power source—it is a fully integrated energy management system. Combining a high-voltage MPPT solar charger, a powerful AC battery charger, and a pure sine wave inverter, the SUNON3.6 delivers industrial-grade performance in a compact, wall-mountable chassis.
Engineered for flexibility, the SUNON3.6 features a massive 4,500W PV input capacity with a high-voltage input range (up to 300Vdc), allowing for longer, more efficient solar string runs. Uniquely, this unit can operate without a battery, powering loads directly from solar and the grid simultaneously—perfect for cabins or backup systems where battery expansion is planned for a later date.
Key Features
- Batteryless Operation: Can power loads directly from solar and utility grid simultaneously without a connected battery bank.
- High-Voltage PV Input: Supports up to 300Vdc open circuit voltage and 4,500W of solar input, reducing wiring costs and simplifying installation.
- Massive Scalability: Parallel up to 6 units (21.6kW total). Supports Single Phase (120V), Split Phase (120/240V - requires 2+ units), and Three Phase (120/208V - requires 3+ units) configurations.
- UL1741 Certified: Meets rigorous safety standards for grid-interactive equipment, ensuring safe operation and easier permitting.
- Generator Auto-Start: Integrated dry contact port sends a signal to start compatible backup generators when battery voltage is low.
- Universal Compatibility: Works seamlessly with RUiXU Lithium batteries (direct communication), as well as Lead-Acid, Gel, and other user-defined 48V battery banks.

⚠️ System Design Notes
To ensure a professional and safe installation, please review the following requirements:
- This unit is for 48V battery systems. It will not operate with 12V or 24V banks.
- For 240V loads (well pumps, dryers, electric stoves), a minimum of two SUNON3.6 units must be installed in parallel and configured for split-phase operation.
- This inverter is IP20 rated and must be installed in a clean, dry, indoor environment.
- Native BMS communication is supported for RUiXU, Pylontech, and other major battery brands via RS485/CAN.
