The UTL Sigma Pro 2KVA / 48V Hybrid MPPT Solar PCU is a versatile, high-efficiency solar power conditioning unit built for smart hybrid operation. It combines solar energy harvesting, battery storage, and grid power to deliver reliable, clean, and continuous power for homes, small offices, and remote installations.

Key to its design is the in-built r-MPPT charge controller, which is up to 30% more efficient than traditional PWM controllers. This ensures you extract maximum energy from your solar panels, even in sub-optimal light. The PCU is controlled by a DSP-based architecture, offering a pure sine-wave output that is safe for sensitive devices like laptops, LED TVs, CCTV systems, and more.

You can choose between multiple working modes — Smart, PCU, Hybrid, or Grid-Export — depending on your load and energy priorities. In Smart mode, it intelligently balances solar, battery, and grid to save on electricity bills. In PCU mode, it gives top priority to solar and battery. Hybrid mode lets it use all three sources efficiently, while Grid-Export lets you feed excess power back to the grid or sync with grid supply.
