1. Solar panels: Solar panels are the core components that convert solar energy into electrical energy. Solar panels convert solar energy into direct current through the photovoltaic effect, becoming the key to photovoltaic power generation.
2. Battery energy storage system: The battery energy storage system can store excess electricity in batteries for emergency use. When the solar panels cannot generate enough power, the battery energy storage system can automatically output the stored power and supply it to users. At present, the commonly used battery types include lead-acid batteries, lithium-ion batteries, and sodium-ion batteries.
3. Inverter: An inverter is a device that converts direct current into alternating current, and is the core component of a photovoltaic energy storage system. Inverters convert DC power into AC power, the same as household or commercial power, so that it can be supplied to consumers.
4. Monitoring system: The monitoring system can monitor the photovoltaic energy storage system in real time, including the output power of solar panels, the power of the battery energy storage system, and the operating status of the inverter. The monitoring system can help users better understand the working status of the photovoltaic energy storage system, improve the efficiency of use, and reduce the failure rate.
