Low Frequency Split Phase Off Grid Solar Inverter

This AN-SPI series low frequency split phase off grid hybrid solar 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 off-grid hybrid solar power inverter is suitable for mains power that is unstable or often off, and important equipment that requires backup power.

How to Use Low Frequency Off Grid Hybrid Solar Inverter without Battery?

The primary way is to directly consume the solar power generated during the day. The inverter will convert the DC power from the solar panels into AC power, which can be used to run your household appliances and devices.

If your hybrid inverter supports grid-tied functionality, you can connect your solar system to the utility grid. During the day, when your solar panels produce more power than you need, the excess energy can be fed back into the grid. At night or during periods of low sunlight, you can draw power from the grid. This setup allows you to benefit from solar energy without needing a battery for storage.

To maximize the efficiency of your home solar system without battery, you should manage the energy consumption to align with solar production. Use high-energy-consuming appliances like washing machines, dishwashers, and air conditioners during peak sunlight hours to make the most of the solar power generated.

Ensure that the low frequency off-grid hybrid solar inverter is configured correctly for a battery-less operation. Some inverters have specific settings or modes for operating without a battery, which can optimize performance and ensure safe operation. Always ensure that your solar installation complies with local regulations and safety standards. Proper installation and configuration by a qualified professional are crucial to avoid any potential issues.
