SNA-US 6K – Split-Phase Off-Grid Battery Storage Inverter
Compact, Reliable Energy Solution for Independent Homes and Remote Sites
Structure & Highlights
The SNA-US 6K is a split-phase, pure sine wave off-grid inverter designed for residential and light commercial applications in areas where grid power is unreliable or unavailable. It integrates three core components — inverter, solar charge controller (MPPT), and battery charger — in one robust, compact unit.
Engineered for split-phase 120/240V systems, it allows simultaneous operation of both low-voltage (120V) and high-voltage (240V) appliances like refrigerators, air conditioners, water pumps, and more. It's ideal for solar-powered homes and remote cabins that require stable and clean energy all day and night.
