Off-grid solar system (Off-grid solar system) is an independent solar power generation system that does not depend on the public grid for power supply. It mainly consists of solar panels, battery energy storage system and inverter. Solar panels convert sunlight into electricity, which is stored in batteries for later use. Inverters convert the DC power stored in batteries into AC power to meet the electrical needs of a home or building. Off-grid solar systems are suitable for areas without grid power or for individuals or institutions wishing to be independent and self-sufficient. It can provide renewable clean energy, reduce dependence on traditional energy, and is also an environmentally friendly energy system. However, the installation and maintenance costs of off-grid solar systems are relatively high, and they need sufficient sunlight to ensure the supply of electricity. In addition, the selection of system capacity and energy storage capacity also needs to be determined according to actual electricity demand.Self-contained: Off-grid solar systems are able to operate independently and do not depend on the public grid for power supply. It is suitable for sites without grid power or where independent self-sufficiency is desired. Clean energy: Solar energy is a renewable and clean energy that converts sunlight into electrical energy through solar panels, does not produce pollutants, and is environmentally friendly. Energy storage: Off-grid solar systems are often equipped with battery energy storage systems, which store excess power generated by solar panels during the day in batteries for use at night or in low-light conditions. Flexibility: Off-grid solar systems can be customized and expanded according to actual needs. The proper battery capacity and number of solar panels can be selected based on energy requirements and available space. Cost Savings: Despite higher installation costs, off-grid solar systems can reduce energy bills and save on fuel costs in the long run, especially in areas without grid power or where conventional energy sources are expensive.1: Q:What's the different between inverter and solar inverter? A: Inverter is only accept AC input, but solar inverter not only accept AC input but also can connect with solar panel to accept PV input, it more save power. 2.Q:What are the advantages of your company? A:Strong R & D team, independent R & D and production of main parts, to control product quality from the source. 3.Q:What kind of certificates your products have acquired ? A:Most of our products have acquired CE, FCC, UL and PSE certificates, which is able to satisfy most country’s importing requirements. 5.Q:How do you ship the goods since they are high capacity battery ? A:We have long-term cooperated forwarders who are professional at battery shipment.1, User solar power supply: (1) Small power sources ranging from 10-100W are used for military and civilian daily electricity in remote areas without electricity, such as plateaus, islands, pastoral areas, border checkpoints, etc., such as lighting, televisions, radio recorders, etc; (2) 3-5 KW household roof grid connected power generation system; (3) Photovoltaic water pump: used for drinking and irrigation in deep water wells in areas without electricity. 2, In the field of transportation, such as beacon lights, traffic/railway signal lights, traffic warning/marker lights, Yuxiang street lights, high-altitude obstacle lights, expressway/railway wireless Telephone booth, unattended road crew power supply, etc. 3,Communication/communication field: solar unmanned microwave relay stations, optical cable maintenance stations, broadcasting/communication/paging power supply systems; Rural carrier telephone photovoltaic system, small communication equipment, soldier GPS power supply, etc. 4, In the fields of oil, ocean, and meteorology: cathodic protection solar power supply system for oil pipelines and reservoir gates, living and emergency power supply for oil drilling platforms, ocean detection equipment, meteorological/hydrological observation equipment, etc. 5, Home lamp power supply: such as garden lamp, street lamp, portable lamp, camping lamp, mountaineering lamp, fishing lamp, Blacklight, rubber cutting lamp, energy-saving lamp, etc. 6, Photovoltaic power plants: 10KW-50MW independent photovoltaic power plants, wind (diesel) complementary power plants, various large parking and charging stations, etc. 7, Solar buildings combine solar power generation with building materials to achieve self-sufficiency in electricity for future large-scale buildings, which is a major development direction in the future. 8, Other fields include: (1) supporting vehicles: solar cars/electric vehicles, battery charging equipment, automobile air conditioners, ventilators, cold drink boxes, etc; (2) Renewable power generation system for solar hydrogen production and fuel cells; (3) Power supply for seawater desalination equipment; (4) Satellites, spacecraft, space solar power plants, etc. Factors to consider in the design of solar power generation systems: 1. Where are solar power generation systems used? What is the solar radiation situation in the area? 2. What is the load power of the system? 3.What is the output voltage of the system, DC or AC? 4. How many hours does the system need to work per day? 5. If encountering cloudy and rainy weather without sunlight, how many days does the system need to be continuously powered? 6. What is the starting current for the load, pure resistive, capacitive, or inductive? 7. The quantity of system requirements.
