How It Works
This hybrid inverter intelligently manages solar power, battery
storage, and grid/generator input to ensure uninterrupted
electricity. Its MPPT technology maximizes solar harvest, while the
bidirectional converter efficiently charges/discharges batteries.
In off-grid mode, it stabilizes voltage and frequency, and in
on-grid mode, it supports feed-in or backup power.
Ideal Applications
✔ Industrial Sites – Mines, factories, and large facilities needing reliable off-grid
power.
✔ Remote Communities – Villages and islands without stable grid access.
✔ Agricultural & Farming – Irrigation systems, livestock operations, and processing plants.
✔ Commercial Microgrids – Hotels, resorts, and data centers requiring energy independence.
✔ Emergency Backup – Hospitals, telecom towers, and critical infrastructure.
