Uninterrupted power. Lower bills. Smarter energy control.

Windsun’s On-Grid Hybrid Solar Systems with LiFePO₄ batteries deliver reliable power, flexible energy flow, and long-term savings for homes, businesses, and industries.

The On-Grid Hybrid Solar System from Windsun Eco Systems blends solar power generation with advanced battery storage, offering unmatched flexibility and control.

Powered by Multi-Flow Technology, this system can route solar energy directly to your loads, batteries, or the grid — all based on your chosen priority settings. Excess energy is stored in LiFePO₄ batteries for night use, backup during outages, or even for export during high-tariff peak hours to maximize savings.

With modular 5 kWh battery packs (wall or rack-mounted), each system can scale up to 320 kWh of total storage without changing the inverter or any other system component. And with a changeover time of less than 6 milliseconds, even your most sensitive electronics run without interruption during power cuts.

How It Works

  • Solar Panels generate DC power from sunlight.
  • Hybrid Inverter with Multi-Flow Tech decides in real-time whether to supply loads, charge batteries, or export to grid.
  • LiFePO₄ Battery Bank stores surplus energy — scalable from 5 kWh to 320 kWh.
  • Smart Discharge powers your home or business during outages, or during peak tariff hours to cut costs.
  • Optional Energy Export from Batteries to the grid during high-rate periods for additional savings (subject to DISCOM policy).

Key Features

  • Multi-Flow Energy Management: Solar can supply loads, batteries, or grid simultaneously based on settings.
  • Peak-Hour Optimization: Use stored energy or export it during expensive peak hours to reduce bills.
  • Ultra-Fast Changeover: < 6 ms switchover from grid to battery ensures continuous power for sensitive loads.
  • Scalable Storage: Start with 5 kWh and expand up to 320 kWh without upgrading other components.
  • High-Efficiency Solar Panels: DCR / Non-DCR Mono PERC Half-Cut Bifacial or Topcon Bifacial modules.
  • LiFePO₄ Battery Technology: Safe, long-life storage with 10-year warranty.
  • Hybrid Inverter with Multiple MPPTs: Optimizes generation from different panel orientations.
  • Pre-Fabricated Hot-Dip Galvanized Structures: Stainless steel fasteners for 35-year corrosion-free life.
  • Real-Time Monitoring: Mobile & web app for generation, storage, and consumption tracking.
  • Full Insurance Coverage: Protects your investment from unforeseen events.
  • MNRE-Certified Engineers: Professional installation and commissioning.
  • End-to-End Services: Design, procurement, installation, approvals, and subsidy processing.

Benefits

  • Continuous Power Supply with < 6 ms switchover.
  • Bill Savings from solar + battery usage.
  • Peak Tariff Advantage — avoid high-rate electricity by using stored energy.
  • Future Ready — expand storage or inverter anytime.
  • Long Life — LiFePO₄ batteries with deep cycle durability.
  • Peace of Mind — 10-year warranty on both inverter and batteries.

Applications

  • Homes wanting backup + savings
  • Small businesses needing outage protection
  • Industrial/Commercial units facing peak-hour charges
  • EV charging stations with solar + battery storage

FAQs

A Hybrid On-Grid Solar System integrates solar power generation with advanced battery storage while remaining connected to the grid. Equipped with Multi-Flow Technology, it intelligently routes solar energy to your loads, charges batteries, or exports to the grid based on your priority settings.
The hybrid inverter assesses your energy needs in real time—solar output can simultaneously power your home, recharge batteries, or feed into the grid depending on your configured priority.
Your system delivers uninterrupted power with a lightning-fast changeover—less than 6 milliseconds—to battery backup. Even the most sensitive electronics remain safely online.
We use modular LiFePO₄ (Lithium Iron Phosphate) battery packs, each of 5 kWh, scalable up to 320 kWh without the need to upgrade the inverter or any other system component.
Yes—stored energy can be exported to the grid during high-tariff peak hours, potentially increasing savings, depending on your DISCOM's policy.
The system features high-efficiency modules such as DCR / non-DCR Mono PERC, Half-Cut Bifacial, or Topcon Bifacial panels for superior power generation.
We use pre-fabricated Hot-Dip Galvanized (HDGI) heavy-duty structures with stainless steel fasteners that ensure a corrosion-free life of 35+ years.
You get real-time mobile and web-based monitoring tools to track generation, battery status, consumption, and system performance.
LiFePO₄ batteries: 10-year warranty
Panels: Efficiency warranty typically ranges from 25–30 years
Inverters: 7–10 years warranty
Structures: Designed for 35+ years of corrosion resistance
A standard on-grid system shuts down during power outages and cannot store or intelligently manage energy flow. In contrast, a hybrid system maintains backup power, allows time-based use of stored energy, and can export excess power—making it highly efficient and resilient.
