Share :
Key Technical Specifications
Capacity: 350Wh Lithium-Ion Battery.
Inverter Type: Modified Sine Wave (Optimized for high-efficiency power delivery).
Charging: 7A AC-to-DC integrated charger + Solar support (up to 20V / 200W).
Transfer Speed: 10ms (Inverter to Mains) / 12ms (Mains to Inverter).
Cooling: Intelligence-driven automatic fan control.
Performance Highlights
1. Industrial-Grade Reliability & Protection
The heart of the system is managed by a State-of-the-Art BMS (Battery Management System). Unlike basic power banks, this unit is equipped with a comprehensive protection suite:
Overload & Short Circuit Protection: Instantaneous shutdown to prevent hardware damage.
Thermal Management: Automatic temperature sensing with fan activation and an over-temperature safety cutoff.
Battery Preservation: Dual-stage "Low Battery" alerts followed by an automatic shutdown to prevent deep discharge, extending the Lithium-Ion lifespan.
2. Seamless UPS Functionality
The Automatic Change Over is the standout feature. With a transfer time of 10ms to 12ms, it functions as a high-speed UPS, ensuring that connected electronics remain powered during a grid failure.
A unique "Grid Stability Delay" is programmed into the system: when mains power returns, the unit waits for 10 seconds before transferring back. This prevents the "chatter" and internal stress caused by intermittent or flickering grid power.
3. Flexible & Fast Charging
Whether you are near a wall outlet or in the sun, the system stays ready. The 7A AC charger provides rapid replenishment, while the solar controller is compatible with 150W–200W panels (up to 20V), allowing for a full recharge in just a few hours of peak sunlight.
Best Use Cases
Emergency Backup: Lighting, fans, and routers, Tv.
Mobile Office: Laptops, tablets, and smartphone charging.
Power Tools: Ideal for brushed motors and devices with internal switching power supplies.
Note: As a Modified Sine Wave unit, it is highly efficient and cost-effective; however, users should check compatibility before using with sensitive medical equipment or high-end audio gear.
