Off-grid Working Principle
FAQ
It's very suitable. 3.5kW is suitable for ordinary households, while 5kW is suitable for large power loads such as multiple air conditioners and water heaters throughout the house. It provides pure sine wave and is safe without harming household appliances.
It supports battery-free startup. On sunny days, photovoltaic power can directly power the load, and during the day, electricity can be obtained without relying on storage batteries.
Yes, with a 2 times surge power design, specifically adapted for the startup of inductive loads such as air conditioner compressors, deep well pumps, and fans.
Support for multiple machines operating in parallel. When the power load increases, you can directly connect them without having to replace the entire set of equipment.
It features pure off-grid independent power supply, making it the top choice for areas without grid power. It can also serve as an emergency backup power source for households with grid power but during power outages.
