Product Introduction

This 120VAC model addresses the specific needs of users in North America and other regions that utilize 120-volt electrical systems. Unlike universal models that require voltage adaptation, this system is purpose-built for seamless integration with standard household outlets and appliances. The wide input voltage tolerance makes it particularly valuable in rural areas or older buildings where voltage sags and surges are common. Whether for home backup during outages, RV power supplementation, or off-grid cabin applications, this system provides reliable, clean power exactly where it's needed most.

Technical Features and Benefits

1. 120VAC/60Hz Optimized Output

The inverter delivers a stable 120VAC ±3% output at 60Hz, specifically designed for compatibility with North American electrical standards. This ensures perfect operation with standard household appliances, tools, and electronic devices without requiring voltage converters or adapters.

• Regional Advantage: Provides plug-and-play compatibility with the majority of consumer electronics and appliances sold in North America.

2. Enhanced Input Voltage Tolerance (90V-140VAC)

With an operational input range spanning from 90VAC to 140VAC, this system can handle significant voltage fluctuations that would cause other backup systems to shut down. This makes it ideal for areas with poor grid infrastructure or frequent brownouts.

• Reliability Benefit: Maintains continuous operation and battery charging even during periods of unstable grid voltage.

3. Pure Sine Wave Inverter Technology

The 1000W continuous/1800W surge pure sine wave inverter produces utility-grade power that is safe for sensitive electronics including computers, medical equipment, and variable-speed motors.

• Performance Advantage: Eliminates the compatibility issues and potential damage risks associated with modified sine wave inverters.

4. High-Efficiency MPPT Solar Charging

The integrated MPPT charge controller operates with up to 99.5% efficiency, extracting maximum power from solar panels even in suboptimal light conditions. The 20A charging capacity supports solar arrays up to 500W for effective off-grid operation.

• Energy Independence: Enables significant reduction in grid electricity consumption through effective solar energy utilization.

5. Comprehensive DC Power Distribution

Multiple DC output options include two 12V ports, two USB-A ports, and two USB-C ports (one with 100W Power Delivery), providing direct power for various devices without inverter conversion losses.

• Efficiency Benefit: Reduces energy waste by powering DC devices directly from the battery system.
