Como se mencionó anteriormente, its investment cost may be relatively high in the early stage and there may be some complexity, such as the need for additional monitoring equipment to observe and use. Al mismo tiempo, it will have certain environmental requirements and basically needs to be installed in an area that avoids direct sunlight.
¿Qué tamaño y tipo de batería debe comprar??
Before continuing to learn more, you should have some understanding of some basic concepts. The battery capacity is measured in kilowatt hours (kWh), and most batteries are modular and can be combined, so satisfactory battery capacity designs can usually be obtained based on demand.
It is worth noting that the term used in lead-acid batteries is ampere hours (ah), which is now largely replaced by kWh and has become a modern industry standard.
1. Understand the daily electricity consumption of households
The first thing you should know is how much electricity your household consumes in kilowatt hours on average within 24 horas, which will be easily calculated when purchasing.
Generalmente hablando, an ordinary household consumes approximately 20-30 kilowatt hours of electricity per day.
2. Consider the influence of seasonal temperature
In summer or winter, the average household’s electricity consumption may be higher or lower. This not only depends on the season, but more precisely on the climate and temperature of your location.
Another factor to consider is the electricity consumption during peak hours, which is usually the time when the electricity bill is highest, and the cost depends on the local power supply bureau.
Modo de fuente de alimentación en el hogar
There are four main power supply methods to choose from in your home.
Conexión a la red (without solar energy)
This is the most primitive and basic setting, and the electricity used in your home comes from the main power grid. There is no solar cell equipment at home.
Grid connected solar energy (without battery)
It is currently a typical household configuration with solar panels in development. There is no home battery backup without solar in this system，and the working setting of the solar panel is to provide power during the day. Families usually use this type of electricity first, and seek help from the grid for additional electricity needed during days with insufficient sunlight, nighttime, and high electricity consumption.
Grid connected solar energy battery (also known as “hybrid” system)
This group includes solar panels, BESS, inversores híbridos (or possibly multiple inverters), and connections to the main grid. Solar panels provide electricity during the day, and households usually use solar energy first. The unused energy is used to charge the battery and store it.
During periods of high electricity consumption, or during extreme weather, nighttime, and days with insufficient sunlight, households obtain electricity from energy storage systems. Smart solar savings will help you have a better daily life.
Off grid
This type is not connected to the national power grid system and is usually used in remote areas where it is not possible to connect to the grid or installation costs are too high.
All of your household’s electricity comes from solar panels or other types of energy such as wind power. Batteries are the main power source and are only used at night and on days with insufficient sunlight. The last backup equipment is usually a diesel generator.
It is usually much more complex and expensive than grid connected systems, and also requires more solar energy storage, which requires battery capacity. It needs an inverter that can withstand high loads, as all usage relies on it, so peak demand needs to be considered. Houses that adopt off grid systems need to be equipped with high-quality energy-saving loads and undergo long-term management and maintenance.
Instalación e integración
Sizing and Capacity:
Regardless of the type of energy storage system, many factors need to be considered when determining components and selecting their sizes.
When designing a plan, the required size should be determined based on the homeowner’s energy needs and storage capacity, taking into account the size of the house, the household’s energy usage, and the average daily production of renewable energy in the local environment.
Installation Process:
The next step is to select the type of battery to be installed. This requires consideration of factors such as your budget, the expected lifespan of the ideal battery type, y necesidades de mantenimiento. After determining the battery type, prepare the installation site. This will involve the size of the battery casing, preparation of electrical connections, and ensuring that there are no potential hazards during construction.
Integration with Renewable Energy Systems:
The final step in the installation process is to connect it to the power system. This involves installing a battery inverter that is compatible with home solar battery bank, which converts the DC stored in the battery into AC power that can be used in the household power system.

Incentivos y consideraciones financieras
Federal and State Incentives:
Some government subsidies or planning policies can provide certain economic compensation to some families in this regard.
Sin embargo, it should be noted that it complies with policy terms, such as the Small Technology Certificate (STC) economic incentives for solar panel systems, which only apply to installed solar panels and not to batteries.
The government will also have some relevant loan plans for you to choose from.This also varies depending on your location and can be accessed on the local government website. These policy plans will be frequently revised, so it is also necessary to determine their timeliness and be sure to keep an eye on the available content in your region in real time.
