What is the difference between Meihua's solar grid-connected inverter and off-grid inverter?

Difference: As the name implies, the grid-connected inverter has a power grid. The output of the solar panel is connected to the input end of the inverter, and the output end of the inverter is connected to the commercial power. Then, home appliances can use the electricity generated by solar panels. Off-grid inverter can't access the mains.
