Generally, the PV generates power to supply home loads first, the excess electricity would be export to grid. But when raining days or at night, the PV can not generate enough power or stop generating, the grid (City electricity) would supply to your home loads.

The connection for on-grid as following:

  • Off-grid appliances of solar energy

Off-grid PV is an independently generator system, no need to connect the grid. It is good for remote areas, island, and the areas where are without city electricity or lack of electricity, etc. Solar street lights(or yard lights), solar flood lights, solar water pump, solar lighting kits, off grid solar home system, are all off-grid.

Generally, a off-grid solar home system consists of solar panels, batteries, controllers and off-grid inverter. In the daytime, the system would produce power and store it to batteries, then the batteries supply to home appliances, such as TV, lights, fridge, even Air conditioner. But pls note that, because of the batteries, the off-grid cost would be higher than on-grid, and the home appliances total working power should be less than the off grid inverter rate power.
