The key to building a home energy storage system lies in precisely matching the capacity of batteries and inverters. The right choice not only maximizes investment returns but also ensures the safety and stability of household electricity usage. This article will sort out the key points for your core selection.

Step 1: Clarify the requirements and calculate the battery capacity

Batteries are repositories of energy, and their capacity directly determines the standby duration. It is recommended to start from the following three steps:

Analyze electricity consumption: Review past electricity bills to understand the average daily electricity consumption of the household (for example: 10 kilowatt-hours per day). This is the basis for capacity selection.

Determine the backup power target: Clearly define which electrical appliances you hope to keep running during a power outage and for how long. Is it only to ensure the basic loads such as refrigerators, lighting and routers (about 2-3 hours), or is it hoped that high-power devices like air conditioners and water heaters can also operate for a long time?

Calculate the battery capacity: Multiply the total power of the target appliance by the expected backup time, and then take into account the inverter conversion efficiency and the depth of battery discharge (lithium iron phosphate batteries can typically reach 90%). For instance, to ensure a basic load of 5 kilowatt-hours per day and considering efficiency losses, a battery system with a capacity of no less than 6kWh can be selected.

Step 2: Power matching, select the appropriate inverter

The inverter is the "heart" of the system, responsible for converting the direct current from the battery into alternating current for household appliances. The core of its selection is power matching:

Continuous power: It must be greater than the sum of the operating powers of all the appliances in use simultaneously. Just simply add up the power of all the essential electrical appliances.

Peak power: It must be capable of withstanding the inrush current generated by the appliances with the highest starting power (such as air conditioners and water pumps) at the moment of startup, which is usually 3 to 7 times the rated power. This is the parameter that is most easily overlooked but crucial in inverter selection.

Step 3: Synergy and Brand

Ensuring the compatibility of batteries and inverters is of vital importance. It is advisable to give priority to brand combinations or all-in-one units that are mutually certified to guarantee stable communication and efficient operation of the system. Finally, choose a brand with a good reputation. They usually offer more guarantees in terms of product quality, safety standards and after-sales service.

In conclusion, scientific planning begins with an accurate analysis of electricity demand. By first determining the battery capacity, then matching the inverter power, and paying attention to brand and compatibility, you can build an efficient and reliable green energy fortress for your home.
