Household photovoltaic energy storage system is mainly composed of intelligent controller, intelligent components, intelligent inverter, intelligent energy storage system and so on. Lithium iron phosphate battery is currently the most widely used household energy storage battery, the role of energy storage battery is to store the excess energy generated by the photovoltaic system during the day, and supply power to household appliances at night. Thus maximize the use of free electricity generated by solar energy, save electricity costs, and realize the use of green electricity for 24 hours. When the public power supply is interrupted in major events such as natural disasters and wars, JDSOLAR household photovoltaic energy storage system can work independently to supply domestic users with electricity. JDSOLAR Inverter is an integrated system that integrates photovoltaic inverter, battery and controller inside. It can display the working status conveniently and intuitively by touch screen. Parameters can be modified and a variety of working modes can be used for easy use.
