Build a battery pack for home not only can save the high cost of electricity during the peak period, but also can cope with a variety of life emergencies (such as power outages), we used to often use the generator is equivalent to a battery pack, with the development of science and technology, and now mainly use batteries as a battery pack for our family, do not need fuel and regular maintenance, and the cost of using is lower than the traditional use of the generator, the specific construction of the The specific steps to build a family battery pack are as follows:
1. What you need to build a home battery pack?
1.1 Battery
1.2 Inverter
1.3 Battery charger
1.4 Cables and connectors
1.5 Fuses or circuit breakers
2. Selecting the battery type
1.1 There are different types of batteries, such as lead-acid batteries, lithium-ion batteries, lithium iron phosphate batteries, gel batteries, etc. Each battery has different characteristics. For example, you need batteries with long service life, high capacity and high safety. If you are a cost-conscious user, you can also choose to use traditional lead-acid batteries, which have a shorter service life and require regular maintenance, but lead-acid batteries are less expensive.
1.2 We recommend you to use lithium iron phosphate battery as the family battery pack, lithium iron phosphate battery life is the longest life of all battery types, can be used for about 8 years, if you pay attention to the maintenance in daily life can be used for more than 10 years. And lithium iron phosphate battery internal BMS (battery management system) can prevent the battery voltage is too high, voltage is too low, temperature is abnormal, current is abnormal and so on, the user can use intelligent equipment to check the battery status, so lithium iron phosphate battery is the best choice as a family battery pack.
3. Choose the right inverter
When building a family battery pack, you need to use an inverter to convert the DC output of the battery into AC power to supply power to the family’s electrical equipment. We need to determine how much power output the inverter will produce, and then add up the wattage of the family’s main electrical equipment according to the family’s energy consumption to choose the right power inverter.
Note: The battery voltage must be the same as the DC input voltage of the inverter, the output power of the inverter must be greater than the power used by the appliances, the positive and negative poles of the inverter must be connected correctly, and the inverter should be placed in a dry and ventilated place.
4.Select battery charger
After choosing a good battery type you can choose the right charger according to the battery, for example, if you choose a lithium iron phosphate battery, make good use of lithium iron phosphate battery special charger or fully intelligent battery charger. Using the right charger can prevent damage to the battery, and can have battery protection features (anti-short circuit, anti-overvoltage, anti-current, etc.). If a solar panel is used to charge the battery, make sure the solar system and the battery are compatible.
5. Choose the battery pack installation location
Battery packs should be installed in the correct location, whether the battery pack is placed outdoors or indoors need to consider the impact of weather conditions, avoid excessive cold, heat, rainy weather, the battery pack is placed in a dry, well-ventilated area.
6. Proper Installation
It is recommended to ask a professional to do the installation, because connecting batteries, inverters to home electricity has certain risks, such as the positive and negative poles of batteries, positive and negative poles of inverters, etc. must be connected correctly, and once an accident occurs, it will jeopardize the individual’s health and safety and the safety of the equipment. If individuals have specialized knowledge can refer to the following installation steps:
6.1 Select thicker insulated cables and safety connectors and use the cables and connectors to connect the battery to the inverter. Note: The positive and negative terminals of the battery and the inverter should be connected correctly during the connection process.
6.2 Connect fuses and switches according to the manufacturer’s instructions, using parallel or series wiring configurations as required.
6.3 Connect the system to the electrical panel using a transfer switch, sub-panel, or specialized receptacle.
6.4 Connect the ground wire from the inverter to the ground wire from the electrical distribution box
To summarize:
When building a battery bank for a home, we need to fully consider our energy needs, and after determining our energy needs, we should consider how to build a battery bank for a home based on the article that mentions choosing the type of batteries, selecting the right inverter, charger, and so on.
