Large ground station is important part of national power generation system applicable on coastal beach, Gobi desert, open area without shade in suburban.

It is consisted of photovoltaic generation system, inverter system and grid access system. The main devices of solar power plant include solar module, mounting system, DC junction box, DC distribution cabinet, on-grid inverter, AC distribution cabinet, boosting transformer as well as power plant monitoring system and environment monitoring system.

Its running mode is that the solar power will be converted into electricity by solar arrays under the condition of the solar radiation, and fed into DC distribution cabinet via DC junction box and converted into active current by on-grid inverter, then connected into the grid through the boosting transformer and finally transmit t the end-user by use of the grid.

Small distributed power plant, refers to smaller photovoltaic power system at user's site or near electricity field to meet specific user’s needs or support the economic operation of the existing distribution network, or satisfy both.

Small distributed power plant is consisted of solar module, mounting system, DC junction box, DC distribution cabinet, on-grid inverter, AC distribution cabinet as well as power plant monitoring system and environment monitoring system. Its running mode is that the solar power will be converted into electricity by solar arrays under the condition of the solar radiation, and concentrated into DC distribution cabinet via DC junction box and converted into AC through on-grid inverter for the load of the architecture itself. The excess or shortage of electricity can be adjusted by connecting with the grid.
