How Much Is The 3 Kw off-Grid Solar Power System Now?

The off-grid solar power system is the main product of JDSOLAR. It is mainly developed for home users and is suitable for general household users for lighting and electrical equipment. The off-grid solar power system uses solar panels to convert solar energy into electricity in the presence of light, powers the load through the solar charge and discharge controller, and simultaneously charges the battery; in the case of cloudy weather or no light, it is controlled by solar charge and discharge. The battery is powered by the battery pack, and the battery is directly supplied to the independent inverter. The inverter is inverter-inverted into AC power to supply AC load. Off-grid solar power generation systems are widely used in remote mountainous areas, non-electric areas, islands, communication base stations and other applications. The system generally consists of a photovoltaic array composed of solar cell modules, a solar charge and discharge controller, a battery pack, an off-grid inverter, a DC load, and an AC load. The photovoltaic array converts the solar energy into electric energy in the presence of light, supplies power to the load through the solar charge and discharge controller, and simultaneously charges the battery pack; when there is no light, the battery pack supplies power to the DC load through the solar charge and discharge controller. At the same time, the battery should directly supply power to the independent inverter, and inverter into an alternating current through a separate inverter to supply power to the AC load.
Factors to consider for off-grid solar power system design:
1. Where is the solar power system used? What is the 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 every day?
5. How many days does the system need to be powered continuously in the event of rainy weather without sunlight?
6, the load situation, pure resistance, capacitive or inductive, how much starting current?
