20 w solar street light price: residential off-grid principle interface connected to the grid system
Residents grid generation system working principle: grid generation system is to residents solar module is installed on the roof, system connected to the grid, common, undertake the task of power supply. Components in the case of sunshine radiation meet the power requirements, system of inverter will light
residential grid-connected power generation system principle of work; Residential grid-connected power generation system is installed on the roof of a residential solar modules. The system is connected to the electricity grid, to share the power supply. In the case of solar radiation in meeting the requirements of the power, the inverter system of photovoltaic power generation system will produce a direct current into alternating current (ac) to direct family load power supply, skimpy share by the mains supply power supply, if the photovoltaic power generation is greater than the family consumption, surplus electricity power grid. The holder of a power system can also choose to integrated photovoltaic (pv) system to produce all the electricity directly into the power grid. However, when the solar radiation cannot satisfy the power demand required by the system, family load required for all power supply directly by the grid. Residential grid-connected power generation system structure is relatively simple, the photovoltaic module, DC switch, inverter and the cable. Residential roof system capacity is related to the roof area size, usually between the 2 kw to 10 kw. The working principle of residential off-grid power generation system; Residential off-grid power generation system working principle and residential grid-connected power generation system is very similar, the difference is off-grid system of power transmission to the public grid, but consumption directly by the load. Considering the volatility of photovoltaic power generation, such as no electricity during the day, sunny day power well, rainy days or not generating electricity with less power, residential off-grid power generation system needs to be equipped with battery ( Group) 。 Off-grid solar power system consists of photovoltaic module, controller, inverter, and battery ( Group) Composition.
