Residential solar storage battery bank size calculator

SHENZHEN, China - April 27, 2021 - PRLog -- How many Kwh battery storage systems I should build for my house. Is 10kwh Lithium ion battery system enough for my residential? Well, Here We would like to share some of basic calculation for your questions:

• Battery capacity . Battery capacity is always related with the battery system voltage. Like 100Ah, 200Ah, 300Ah
  
  
• Battery system Power– This is the most easy understand way to know a battery system. In Kwh. Like 5kwh , 10kwh or 20kwh.
  
  
• Solar storage battery system voltage– Most popular 48v/ 51.2v and 12v. 12.8 volt. And now high voltage like 400v.
  
  

Calculator in Kwh of battery storage systems

This is the most comprehensive way to communicate with your electrician. Know how many battery is required. We have to find out how many kwh is required by your home. What is the comsum power each day. Knowing this by adding all your applications in kw. and how long each application runing during 24 hours.

For example: Jack has a list as following

• 3 Air condition
• large screen tv
• refrigerator
• lighting
• water heating system

Accroding the acture use in each day. His house will comsum 10kwh everday. If he is plan to use Lithium ion or LiFePo4 battery storage system at 48volt./51.2v. The calculation as following:

10kWh x 1.2 (for 80% depth of discharge) x 1.05 (inefficiency factor) = 12.6 kWh

So.  Jack will install a system 12.6 kwh. or above. 15kwh will be the best choice.

To sizing and calculation about the solar storage battery bank. We need to know how many power we use for daily. Based on 10Kwh power we use for a day. Here is an example for your better understanding.

The battery storage capacity should slightly exceed the power generation potential of your system to ensure batteries are not stressed too much.

Ideally the battery should store enough usable power to supply energy for one full 24 hour period. The next day there should be a power source to fully recharge it. The battery bank should be large enough to support the power and load maximum requirement safely and without damaging or shortening the life.
