Sigma Pro Solar Inverter 15kVA / 180V

The Sigma Pro Solar Inverter 15kVA / 180V is a high-performance Hybrid Solar PCU (Power Conditioning Unit) designed for reliable solar energy management in residential, commercial, and small industrial applications. This single-phase bi-directional inverter efficiently manages power between solar panels, batteries, and the grid.

With grid export functionality, the inverter allows excess solar energy to be exported to the grid while also importing power when solar generation is insufficient. This ensures an uninterrupted electricity supply and maximum utilization of solar energy.

Available through Narayana Solar – a trusted solar solutions provider in India, the Sigma Pro 15kVA inverter helps reduce electricity bills while providing stable and efficient power backup.

Key Features

• Hybrid Solar PCU with grid export capability

• Bi-directional inverter (power import and export from grid)

• High efficiency performance for reliable solar power management

• Single-phase output system

• Smart energy management between solar, battery, and grid

• Uninterrupted power supply during power outages

• Solar priority battery charging for maximum solar utilization

Operating Modes

Stand-Alone Mode

In stand-alone mode, the inverter operates using solar panels and batteries to generate AC power. The battery is charged primarily by solar energy, while the grid acts as a secondary source.

Grid Interactive Mode

In grid interactive mode, the inverter works in parallel with the grid supply. Any excess solar power generated is exported to the grid, and when solar generation is low, the inverter draws the required power from the grid.

Applications

The Sigma Pro Solar Inverter 15kVA is suitable for:

• Residential solar systems

• Commercial buildings

• Offices and institutions

• Shops and small industrial setups

• Solar rooftop installations
