Product Detail

Off-Grid Solar System


ECENER provides off-grid solar system with superior quality. Our regular class and type ranging from 1KW, 2KW, 3KW and 5KW. We can also provide off-grid solar systems more than 5KW.


Descriptions


Off grid solar system is typically usedin no power areas such as remote mountain areas, islands, communication baseand other applications. The system is typically composed of PV array, solarcharge controller, battery group, off-grid inverter, DC load and AC load, etc.

Off-grid solar system uses solar panelsto convert solar energy into electricity when there is sunlight. It supplies powerto the load through solar charge controller, and charges the battery group atthe same time. In cloudy or rainy days, it supplies power to the DC loadthrough solar charge controller, at the same time, the battery also suppliespower to off-grid inverter and the current is converted to supply power to AC load.

Principle of solar power generation


There are two ways of solar powergeneration, one is “light to heat to electricity” conversion, the other is “lightelectricity” direct conversion.

The “light to heat to electricity”conversion mode uses heat energy generated by solar radiation to generateelectric power. Usually, the heat energy absorbed by solar heat collector isconverted into steam of work medium, and then the steam turbine is driven togenerate electric power. The former is optical thermal conversion process whilethe latter is thermal electrical conversion process.

The “light electricity” conversion modeis to use the photoelectric effect to convert the solar power into electric powerdirectly. The basic device of “light electricity” conversion mode is solarcell. Solar cell is a device that directly converts sun light energy intoelectric power due to photovoltaic effect. It is a semiconductor photodiode.When the sun shines on the photodiode, the photodiode will convert the sunlightenergy into electric power and generate current. When many cells are connectedin series or in parallel, solar cell arrays with relatively high power areformed.


Points to be considered for thedesign of solar power system:


1. Where is the off-grid solar systemused? What is sunshine condition in the area in the whole year?

2. What is the value of load power ofthe off-grid solar system?

3. What is output voltage of theoff-grid solar system, DC or AC?

4. How many hours does the off-gridsolar system work in each day?

5. How many days of continuous powersupply does the off-grid solar system need during cloudy and rainy days?

6. Descriptions and details of the load,pure resistance? Capacitance? Or inductance? What is the starting current value?
