Collection: UTL Sigma Solar Hybrid Inverter Single Phase

The UTL Sigma Hybrid Inverter is engineered with state-of-the-art technology, prioritizing solar energy and ensuring power continuity.

  • True Hybrid Functionality (Grid-Tie + Backup): It operates in both Stand-Alone (Off-Grid) and Grid-Interactive (On-Grid/Net Metering) modes. You can export surplus solar power to the grid to earn credits and store solar energy in batteries for backup during power outages.

  • rMPPT Charge Controller: Equipped with an rMPPT (Rapid Maximum Power Point Tracking) charge controller, the Sigma+ ensures up to 30% higher efficiency than standard inverters, maximizing the yield from your solar panels.

  • DSP-Based Pure Sine Wave Output: The Digital Signal Processor (DSP)-based design provides a stable, pure sine wave output, which is essential for running sensitive and expensive home appliances like air conditioners, refrigerators, and computers safely.

  • Priority-Based Working Modes: The inverter features user-friendly, switchable operating modes (Smart/PCU/Hybrid) allowing you to dictate the power preference (e.g., solar, battery, grid) based on your needs and local utility policies.

  • Lithium and Lead-Acid Compatible: The UTL Sigma Pro models support both traditional lead-acid and modern, high-performance lithium-ion (LiFePO4) batteries, offering flexibility for your energy storage choice.

  • Remote Monitoring: Standard or optional Wi-Fi/GSM modules allow you to monitor all AC and DC parameters, generation, and consumption remotely via a dedicated app, giving you real-time control over your system.
