SNA 12–14K – Single Phase Off-Grid Battery Storage Inverter
High-Capacity Off-Grid Power for Energy Independence & Resilience
Structure & Highlights
The SNA 12–14K inverter is a high-performance all-in-one off-grid solar inverter designed to deliver stable, uninterrupted power to large households, businesses, or remote areas. It integrates a pure sine wave inverter, MPPT solar charge controller, and battery management system, allowing direct operation from solar power and stored battery energy — completely independent of the utility grid.
This model supports high surge loads, larger PV arrays, and lithium/lead-acid batteries, making it perfect for users requiring robust energy storage and solar power conversion in a single, scalable solution.
Highlights:
✅ Off-grid inverter for homes & facilities with high energy demand
✅ True hybrid control: solar, battery, and generator integration
✅ Wide MPPT input range for flexible solar design
✅ Built-in LCD and smart communication for ease of use
✅ Ideal for remote/rural India and areas with unreliable grid power
