Problems solved by technology
The known energy storage power supply is composed of an energy storage battery pack, a protection circuit, and input and output ports. It uses a charger for charging. The external power supply can only be commercial power, which does not have a DC charging function and cannot be connected to a photovoltaic power generation system. This kind of energy storage power supply cannot be connected to new solar energy, and cannot meet the needs of users for new energy utilization.
The independent solar power supply system mainly uses batteries to store energy, but when the batteries are not charged in time due to weather or other reasons, the batteries will be in an over-discharge state and cannot supply power to the load.
For many household appliances, continuous power supply is required, which requires flexible switching between solar photovoltaic power generation and urban grid, and both power supply methods must be able to meet the power requirements of AC loads and DC loads at the same time, so as not to Damage to electrical equipment or interruption of power supply
