How solar energy storage systems power homes
What is a photovoltaic energy storage system? A photovoltaic energy storage system is a combination of equipment and technology that converts solar energy into electrical energy to supply household appliances while storing the excess for use at night or in the absence of utility power.
Its main components are the following:
Photovoltaic module: It consists of several photovoltaic modules (also called solar panels), which are responsible for capturing sunlight and converting it into direct current.
Racks, accessories and cables: used to hold the solar panels and to transmit the generated DC power to the inverter.
lithium battery inverter (grid connected and off grid inverters) : convert the DC power generated by the solar panels into AC power to supply household appliances, and store the excess power in an energy storage system, which can also be connected to the city power grid.
lithium home battery: Usually refers to batteries, such as lithium batteries and other types of batteries, which store electricity generated by solar energy that is not used immediately through an inverter for later use.
EMS and BMS: EMS is to monitor and manage the operation of the entire system to ensure that all parts work efficiently and safely. BMS is the management system of the storage battery, optimizing and controlling the battery charging and discharging.
convergence box: including all kinds of protection equipment and switches, such as surge protection (lightning protection) in the middle of the solar access inverter, fuses, DC circuit breakers, utility input circuit breakers, uninterruptible power supply output circuit breakers and so on.
First of all, a home energy storage system needs solar panels. Solar panels convert sunlight into usable electricity that can power the home. Then, the solar panels convert the excess power into electrical capacity stored in the accumulator home energy storage, which can be released from the battery when it is needed for use.
The heart of a home energy storage system is the battery, so it's important to choose the right one. Home energy storage batteries on the market are usually divided into several types: leadacid batteries, rechargeable li battery, and lithium ion iron phosphate batteries. Leadacid batteries are cheaper but have a shorter lifespan, while lithiumion batteries are more durable but more expensive. Lithium iron phosphate batteries, on the other hand, are a bit safer. In addition, the capacity of a home energy storage battery needs to be determined based on the household's electricity consumptionand the output of the solar panels.
