Go completely energy independent with Windsun’s advanced Solar Off-Grid Systems.

Store your own clean energy for day and night use, with the option to integrate a windmill for a second renewable source — reducing battery size and giving you 24×7 green power.

The Solar Off-Grid Power System from Windsun Eco Systems is the perfect solution for areas with unreliable grid supply or no grid connection at all. It stores solar power in batteries so you can run your home, business, or farm 24×7 without depending on the utility.

As an advanced option, we can integrate a windmill with the off-grid system. This provides a second renewable energy source, especially at night, reducing the required battery capacity and increasing reliability.

Smart charging flexibility: Our hybrid controller allows batteries to charge from solar, windmill, or even grid supply, based on user-defined charging priority settings. This ensures your batteries are always ready, even in prolonged cloudy or windless conditions.

Whether you choose pure solar or solar + wind hybrid, we provide MNRE-certified engineering, premium components, and end-to-end services — from design to installation, insurance coverage, and long-term support.

How It Works

• Solar Panels generate DC electricity from sunlight.
• Windmill (optional) provides additional DC or AC power input.
• Charge Controller / Hybrid Inverter regulates charging and converts power for use.
• Battery Bank stores excess energy for night or low-generation periods.
• Optional Grid Charging ensures uninterrupted power even in extended bad weather.
• Load Supply — clean AC power for appliances, lighting, and equipment.

Key Features

• High-Efficiency Solar Panels: DCR/Non-DCR Mono PERC Half-Cut Bifacial or Topcon Bifacial modules.
• Hybrid Energy Input: Supports solar + wind + grid charging options.
• Charging Priority Settings: Choose charging order — solar first, wind second, grid last — or customize based on your needs.
• Mounting Structure: Pre-fabricated hot-dip galvanized steel with stainless fasteners for 35 years corrosion-free life.
• Inverter Options: Off-grid/hybrid inverter with MPPT & multi-source charging.
