DC Solar Power SystemDC Solar Power System, what does grid-connected mean?
DC Solar Power System, grid-connected means that photovoltaic power generation is converted into AC through inverters, connected to the grid through boost or direct low-voltage side, and used by the grid for power dispatch.
It is understood that the grid connection is not complicated, but also free installation and access. It is only necessary to connect the network controller and the bidirectional meter on the original household cables, and no additional transmission lines need to be installed. Controller and bi-directional ammeter have the functions of power metering and power generation metering. It is no difference how much power is sent to the power grid and how much power is used in the power grid. Users who have installed distributed generators before can also apply to the power supply company at any time to sell the surplus electricity to the grid as long as they meet the grid-connected conditions.
