Single-Phase New Type Inverter Power Supply

Product Overview:

The off-grid inverter adopts SPWM (Sine Pulse Width Modulation) technology, which converts high-voltage DC into pulse sequences with gradually varying pulse widths by controlling the switching timing of IGBT modules. After filtering and shaping through the filter circuit to remove high-frequency harmonics, the voltage pulse sequence is transformed into smooth sinusoidal AC power. The power quality meets the standard of mains power and is suitable for all types of loads.

Off-grid inverters perform exceptionally well in medium to large-scale photovoltaic power generation systems due to their high efficiency, reliability, and wide input voltage range. They effectively convert DC power to sinusoidal AC power, ensuring output accuracy fully meets rated load requirements. With a soft-start function, they prevent high current surges that could damage batteries and loads. These inverters can operate normally across a wide range of temperatures, humidity levels, and at high altitudes, adapting to various geographical environments and climatic conditions.

Application Scenarios:

Based on the characteristics of off-grid inverters, their application scenarios primarily include power supply in remote mountainous areas, electricity-free zones, backup power sources, and independent power supply systems. They ensure the stability of the entire power system during grid instability.
