The electric energy storage system "stitches" intermittent renewable energy sources, stores electrical energy through batteries, and releases the stored energy to generate electricity when needed. Therefore, lead-acid batteries, which are important components of power supply systems such as wind energy storage, and photovoltaic energy storage etc, are also an important guarantee for the normal operation of power supply systems.
Solar street light system is composed of solar module, battery, controller, light source, bracket system and its various accessories. The working principle is to use solar modules to absorb sunlight and convert it into electrical energy and store it in the battery through the controller. When night comes (or when the sky is not bright enough), the controller then controls the battery to power the high-efficiency energy-saving LED light source to achieve ambient lighting.
The grid-connected home energy storage system consists of five parts, including solar cell arrays, grid-connected inverters, BMS management systems, battery packs, and AC loads. The system uses a hybrid power supply of photovoltaic and energy storage systems. When the mains power is normal, the photovoltaic grid-connected system and the mains power supply power to the load; when the mains power fails, the energy storage system and the photovoltaic grid-connected system jointly supply power.
The wind-solar complementary power generation system uses two types of wind power generators and solar battery square array power generation equipment to jointly generate power. It uses a solar battery square array and a wind generator (converts AC power to DC power) to store the generated energy in a battery pack. When power is needed, the inverter converts the DC power stored in the battery pack into AC power and sends it to the user's load through the power transmission line.
