There are three kinds of solar power systems: On-Grid, hybrid, off Grid.
Grid-connected system: Firstly, solar energy is converted into electricity by solar panels; The grid-connected inverter then converts DC to AC to supply power to the appliance. The online system requires no batteries and is connected to a public grid, so smart meters are needed first. This type of system can help reduce the cost of electricity and also sell electricity to the public grid, if your government has a policy to encourage private sale of electricity to the public grid, this type of system would be perfect.
Off-grid system: First, solar panels complete the conversion from sunlight to electricity; Secondly, the combination box completes the current combination from the solar panel; Third, the controller will control the battery charge and discharge; Fourth, the off-grid inverter converts DC into AC and then supplies power to electrical appliances. Off-grid systems, which require batteries as backup, are typically used in places where there is no grid, such as islands. It can also use a generator as a backup.
Hybrid system: First, solar panels convert solar energy into electricity; Secondly, the combination box completes the current combination from the solar panel; Third, the battery by charging and discharging to store electricity or work; Fourth, the hybrid inverter converts DC to AC and then supplies power to the appliances. Hybrid power system is a combination of off-grid and grid-connected, which has the advantages of off-grid and grid-connected, but also has high cost. If you have a utility grid in your area but have frequent power outages, choosing this system will help you lower your electricity bill, as well as sell electricity to the utility grid.
