Photovoltaic grid connected cabinet PV power generation system

Short Description:

The photovoltaic grid-connected cabinet is the equipment utilized to convert the direct current energy generated by the photovoltaic power generation system into alternating current energy and inject it into the power system via the connection point. Generally, the photovoltaic grid-connected cabinet is composed of a DC input, an inverter, an AC output, a protection device, and a monitoring system. Through the inverter, it converts the DC power output by the photovoltaic cell pack into the AC power required by the power system, thereby realizing the seamless grid connection between the photovoltaic power generation system and the power system. The photovoltaic grid-connected cabinet achieves efficient energy transmission between the photovoltaic power generation system and the power system mainly through seamless docking with the power system.

Overview details

CSGGD, CSJXF for large-scale photovoltaic grid-connected power generation systems.In order toreduce the connection line and power loss between the inverter and the grid-connected cabinet, it isconvenient to maintain and improve reliability, Generally, an AC combiner box is added between theinverter and the grid-connected cabinet, and the current is configured according to the power oftheinverter. In order to meet this requirement, Im is specially designed to be combined with photovoltaicinverter products to form a complete photovoltaic power generation system solution. The use oftheconfluence AC box allows the user to customize the current and voltage according to the AC and gridrated input current.This product is mainly used in the grid-connected line ofdistributedphotovoltaic system 100Kw-1Mw.

working principle

1. The output DC power of the photovoltaic cell pack can enter the photovoltaic grid-connected cabinet through the DC input terminal of the cabinet. 

2. The inverter within the photovoltaic grid-connected cabinet converts direct current energy into alternating current power and synchronizes the frequency and phase with the power system.
3. The inverter injects the generated AC power into the power system through the AC output terminal, thus establishing a power transmission channel between the photovoltaic power generation system and the power system. 
4. The background monitoring and control system of the photovoltaic power station monitors and manages the operating status of the photovoltaic grid-connected cabinet in real time to ensure the safe and stable operation of the photovoltaic power generation system.

Conditions For Use

 

Ambient air temperature shall be neither above+40°C nor below-50°CIndoor installation and use,the altitude ofthe use venue shall not exceed 2000MEnvironment relative humidity shall not exceed 50% at the maximum temperature of40°C,highrelative humidity is allowed when the temperature is comparatively low.(for example,it can be90%at +20°C).Also,the impact brought about by occasional condensation due to temperature changeshall be taken into consideration.
The gradient to vertical plane shall not be more than 5 degrees when equipments installation.Equipments shall be installed at places free from excessive vibration and impaction,and where noerosion shall be caused to the electric appliance components.
IF users have any special requirement,please negotiate with the manufacturer for settlement..
