The hybrid home PV + energy storage system mainly consists of the following components:
Photovoltaic modules: As the primary energy source of the system, photovoltaic modules convert solar energy into direct current. Depending on the electricity needs of the home and the available space, users can choose different numbers and types of photovoltaic modules.
Grid-connected inverter: The direct current generated by the photovoltaic module needs to be converted to alternating current for home use, and the grid-connected inverter is responsible for this conversion process. In addition, the inverter can also transmit excess power to the public grid, so that users can be compensated for their electricity bills.
Energy storage system: Energy storage components are usually lithium batteries or lead-acid batteries, which are responsible for storing excess energy generated by photovoltaic systems during the day. The energy storage system ensures that users can still obtain power supply on cloudy days or at night, improving energy flexibility and reliability.
Energy Management System (EMS) : Intelligent energy management system can monitor power generation, electricity consumption and energy storage in real time, and automatically adjust the energy flow of photovoltaic, energy storage and grid according to demand, to achieve the best energy scheduling.
Load: Including all appliances and equipment in the home, the energy management system will rationally allocate photovoltaic power generation and stored electricity according to the load demand.
