The selection of household energy storage batteries should be based on multiple factors such as the actual needs, budget, and installation environment of the household. Here are some suggestions for selecting the capacity of household energy storage batteries:

Capacity requirements:

The capacity size of household energy storage batteries generally ranges from 2kWh to 10kWh, and the capacity size of batteries from different brands and models may also vary.

A 2kWh household energy storage battery can store approximately 1kW of energy, equivalent to the electricity demand for one hour of continuous use. A 10kWh household energy storage battery can store 5kW of energy, which is equivalent to the electricity demand for continuous use for 5 hours.

Based on the daily electricity consumption of households, the required capacity of energy storage batteries can be estimated. For example, if the average daily electricity consumption of a household is 5kWh, choosing a 10kWh energy storage battery can ensure that sufficient electricity is provided to the household during power outages or peak hours.

Budget considerations:

The price of energy storage batteries may vary depending on factors such as capacity, brand, and technology. If budget allows, larger capacity batteries can be chosen to meet the longer electricity needs of households.

At the same time, factors such as battery installation, maintenance, and replacement costs also need to be considered.

Installation environment:

Home energy storage batteries need to be installed in a dry, ventilated, and safe place to avoid adverse environments such as high temperature, humidity, and sources of ignition.

The installation position also needs to consider the weight and volume of the battery to ensure the safety and convenience of the installation process.

Technical selection:

The mainstream household energy storage battery technologies in the current market include lithium-ion batteries, lead-acid batteries, etc. Among them, lithium-ion batteries have advantages such as high energy density and long cycle life, but their prices are relatively high; Lead acid batteries, on the other hand, have lower prices but lower energy density and cycle life.

According to the actual needs and budget situation of the family, suitable technology types can be selected.
