Low Frequency Off Grid Solar Inverter

Low Frequency Off Grid Solar Inverter
This AN-SPI series low frequency off grid string inverter uses 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 solar inverter off grid 1000w, 3000w off grid solar system is suitable for mains power that is unstable or often off, and important equipment that requires backup power.
