How Much Home Battery Storage Do I Need

In today's era of energy saving, solar power generation systems are closely linked with us, and in order to better save energy, we must use household batteries to store the excess energy generated by solar energy, and then release it when needed.

Calculate how much electricity your household uses in a day

First of all, take the Australian family as an example, the electricity consumption of a family in Australia is about 16KWh, and if there are other large electrical appliances in the home, the electricity consumption is more than this. Most Australian households are engaged in nine-to-five jobs, so they use about 30% of their electricity during the day, and 70% of their electricity at night, so you can calculate that they use about 5KWh during the day and 11KWh at night.

1. All household appliances will have a power label when they are purchased, indicating their rated power, which is the basic data for calculating electricity consumption. For frequently used appliances, such as televisions, refrigerators, etc., the average use time of the day can be estimated.

2. Then calculate the electricity consumption of the appliance according to the rated power and daily use time of the appliance. The total electricity consumption of the household can be obtained by adding up the electricity consumption of all the appliances.

3. The price of electricity in different time periods may be different, so when to use battery electricity and when to use mains electricity depends on the reasonable planning of your own family.

Need to take into account the solar home storage system space

1. If you need to buy home batteries, you must first determine whether the home space is suitable for floor-mounted home batteries or wall-mounted home batteries, which has a great relationship with the spatial layout of your family.

2. We plan to purchase home batteries not only need to consider batteries, but also need to consider the number of solar panels. We first need to know how much solar input power is supported by the household battery, and then we can configure the number of solar panels according to the input power, so we need to have enough space to put so many solar panels.

3. The amount of electricity produced by the solar panels determines how much they can charge the battery system during the day. It is important to determine the size of the solar panel and battery storage system to make them work together; There is no point in installing a large battery if you will never utilize its full capacity. Monitoring solar panel production can help you understand how many solar cells you actually need.

In general, household battery capacity is closely related to household electricity consumption, and household electricity consumption is a complex issue, which is affected by a variety of factors. By understanding these factors, we can calculate the average daily electricity consumption of the home, and then configure the home battery and solar power system.
