01 Product Description
PV Off-grid System is a high-performance off-grid solar power supply solution. Stable control is achieved through a dual-core MCU architecture, supporting flexible switching among three modes: mains power mode, energy-saving mode, and battery mode, to meet the diverse power consumption scenarios. The system provides pure sinusoidal AC output, which is suitable for precision equipment and conventional electrical loads. The wide voltage input range and fully automatic voltage regulation function ensure the accuracy of power output, and the LCD screen monitors the operating status in real time.
It is equipped with multiple protection mechanisms such as overcharge, high and low voltage, overload, short circuit and overheating, providing safe and reliable new energy power support for areas without grid coverage such as households, industries, border defense and ships.
Advantage
