First, it is necessary to determine whether the system is a grid-connected system or an off-grid system.
The inverter for the off-grid system is selected based on the load. It depends on the capacity and characteristics of the load. If the load is 5 kW, you should choose at least a 5 kW inverter. Not required. Module power; The inverter of the grid-connected system is selected according to the module capacity, which is generally equivalent to the module capacity. For example, for a 3 kW module, choose a 3 kW grid connected inverter. The grid-connected system uses 3000W components and a 5000W inverter. As long as the configuration is reasonable, there will be no problems in normal operation. However, the inverter is not operating at full capacity, which is a bit excessive.
Grid-connected system refers to a system that depends on energy from the gridto produce electricity. This system must be connected to the network. Then the grid-connected inverter will detect the system's electrical performance parameters. network, sync with them, then connect to the network.
An off-grid system is one that does not rely on grid energy to produce electricity. This system cannot be connected to the grid and generate its own electricity for charging. It is usually found in remote areas, areas without a power grid or small photovoltaic products, such as solar flashlights.
