Process of design

The entire design process
According to the information provided by the customer above all with the electrical parameters and daily use of time, I designed the company can set you free photovoltaic system configuration.
1 The main system components:
Solar photovoltaic power generation systems, including according to your system type, site location and application, different components should be selected. Solar photovoltaic systems main component is the solar cell modules and charge controller, inverter, battery, auxiliary energy and load (electrical).
A. Solar cell module: converted into DC charging current.
B. Solar Charge Controller: According to the PV panel voltage and current to determine. To prevent battery overcharge and over discharge, extend battery life.
C. Inverter: The DC into AC equipment.
D. Solar batteries: energy storage device, (if necessary, to increase the auxiliary energy: diesel generators or other renewable energy sources.)
2 scale solar photovoltaic power generation system
Determine the size and number of PV modules: in the design of a solar photovoltaic power generation system The first step is to find the total power and energy consumption of all loads, solar photovoltaic power generation system needs to provide as follows: 1 per day, calculated devices use the total watts consumed when .2 Calculate the total watt-hours to provide the required daily power PV modules .3 Identify components of a single block of photovoltaic power: PV modules of different sizes will produce different power, to find out the size of PV modules, the total wattage of the value depends on the size of PV modules and site location of the climate and we must take into account the PV modules in different locations on each site battery pieces influence the total wattage and finally calculate the required number of PV panels
3 to determine the specifications of the inverter is used in the inverter output AC power required system. The rated input should not be less than the total watts of electrical appliances, inverters and batteries must have the same rated voltage for and power generation systems or grid connected systems, the rated input level should be the same with the photovoltaic array, to safe and efficient operation.
4 Make sure the battery size and quantity: It is recommended to use a specially designed deep cycle batteries for solar photovoltaic power generation system that can maintain long-lasting quick charge or the charge and discharge cycles, battery capacity should be large enough to store enough energy during the night and rainy days can supply.
5 to determine the specifications of the solar charge controller solar charge controller is usually determined by the voltage and current specifications of the old, the selection and PV array and battery pack voltage and current to match the solar charge controller, and then determine which type solar charge controller is appropriate.
In this way, the entire system configuration is determined, the following products can be ordered and installation and commissioning
