How much do you know about 3kw off grid solar system？

Composition and function of 3KW off grid power generation system

Solar panel: the core part of the 3KW off grid solar system, and the most valuable part of the solar power system. Its function is to convert the radiation capacity of the sun into electrical energy, or send it to the battery for storage, or drive the load to work.

Solar Mounting Bracket: Fix the solar panel. According to different installation methods, solar installation brackets are divided into roof installation and ground installation; among them, roof installation is also divided into glazed tile installation and color steel tile installation; due to the different design of brackets for different installation methods, customers need to confirm in advance when purchasing.

Solar charge controller: The function of the solar controller is to control the working state of the entire system, and to protect the battery from overcharge and overdischarge. In places with large temperature difference, a qualified controller should also have the function of temperature compensation. Other additional functions such as light-controlled switches and time-controlled switches should be optional on the controller.

Fully sealed solar colloidal battery: 12vDC 150Ah stores the electricity generated by the solar panel when there is light, and releases it when needed.

Solar Inverter: The direct output of solar energy is direct current. In order to provide electrical power to 220VAC electrical appliances, it is necessary to convert the DC power generated by the solar power generation system into AC power.

2. Application of photovoltaic off-grid power generation system

Household solar power: used in remote areas without electricity, such as plateaus, islands, pastoral areas, border posts and other military and civilian life electricity, such as lighting, TV, tape recorders, etc.;

Home lighting power supply: such as garden lamps, street lamps, portable lamps, camping lamps, mountaineering lamps, fishing lamps, black light lamps, tapping lamps, energy-saving lamps, etc.

In the field of transportation, such as beacon lights, traffic/railway signal lights, traffic warning/signal lights, Yuxiang street lights, high-altitude obstruction lights, highway/railway wireless phone booths, unattended road class power supply, etc.

Communication/communication field: solar unattended microwave relay station, optical cable maintenance station, broadcasting/communication/paging power supply system; rural carrier telephone photovoltaic system, small communication machine, GPS power supply for soldiers, etc.

Petroleum, marine and meteorological fields: cathodic protection solar power systems for oil pipelines and reservoir gates, life and emergency power supplies for oil drilling platforms, marine testing equipment, meteorological/hydrological observation equipment, etc.

Solar buildings combine solar power generation with building materials to make future large buildings self-sufficient in electricity, which is a major development direction in the future.
