Low Frequency Off Grid Solar Inverter

This AN-SPI series low frequency solar inverter use high speed power transistors to invert the DC voltage to AC power, and it drives transistors at the same power frequency (50Hz/60Hz) as the AC sine wave power output voltage. That is much lower than the high frequency inverters working at a few hundred thousand Hz or more. Low frequency transformer enables the inverter to operate with all kinds of home appliances. This low frequency off-grid solar inverter is suitable for mains power that is unstable or often off, and important equipment that requires backup power.
