In this article, I will discuss the types of home energy storage solutions, their benefits, and many more. So, read on to find out!
What Is Residential Energy Storage?
Furthermore, you can find these energy storage solutions in the form of batteries. They have different features and specifications. For instance, some batteries are more efficient than others. On the contrary, some batteries have more heat resistance compared to other batteries.
Benefits Of A Residential Energy Storage
- A residential energy storage system uses solar panels instead of fossil fuels to generate electricity. Consequently, there is a reduced carbon footprint, which promotes environmental sustainability.
- A home storage solution allows you to use electricity for 24 hours without relying on a municipal power grid. Moreover, you can use these energy storage systems even when there are blackouts.
- The residential energy storage system supplies the stored energy from the grid on demand. As a result, you can get the power supply equally without any disruption.
How Residential Energy Storage Works?

Step 1: At first, the solar panels take energy from the sunlight during the day.
Step 2: Then, an alternating current generator converts the solar energy into current energy.
Step 3: The current generator is connected to the battery rack. So when home appliances are powered, the excess energy travels back to the battery rack, which stores the energy there.
Step 4: The battery rack supplies the energy to the household when the sun is out. So, you can use this energy during peak hours or when the temperature is high. Moreover, you can use this energy storage system anytime without facing blackouts.
Factors To Consider Before Choosing A Residential Energy Storage
Battery Lifespan
Various batteries have different lifespans. Hence, you should make sure that the battery has a longer lifespan. So, take a look at the below table to know the longevity of different batteries:
| Battery Type | Battery Lifespan |
| Lithium-ion batteries | 10 to 15 years |
| Lead acid batteries | 2 to 3 years |
| Sodium sulfer batteries | 15 years |
| Redox flow batteries | 10 years |
Battery Power Rating
A battery’s power rating determines how much power consistency it can provide to your household appliances. So, if you want a continuous power supply without any disruption, you must select a high-power rating battery. However, if you choose a high power rating battery with a low capacity, then the battery lifespan will reduce.
Energy Storage Capacity
The residential energy storage you choose must have sufficient energy storage capacity to meet the power demand. If your household needs energy consumption, like 8 kWh, it won’t be suitable for a storage capacity of 5 kWh. So, you need to make a wise decision.
Warranty
The warranty makes sure that the residential storage systems work at their best within a particular year. Besides, you can replace the energy storage system if it goes bad before the given warranty year. However, BST Power provides residential energy storage systems with the same and scalable warranty period for these batteries. Check this table out to find out more:
| Residential Storage Systems | Warranty |
| Wall Mounted Energy Storage | 5-10 years |
| Rack Mounted Energy Storage | 5-10 years |
| Stacked Energy Storage Battery | 5-10 years |
Integrations
You need to ensure that the system integration is flexible enough to install any type of battery when required. Additionally, it should be also compatible with your solar panels. Besides, the solar panel and the system integration should be able to communicate effectively.
Safety Rate
Some home energy storage solutions offer better safety ratings than others. For instance, if cells in a battery experience failure, then it is hazardous as it leads to fire. So, a battery with a good safety rating can reduce the fire risk.
Cost
The cost of the residential energy storage system stands anywhere between $19000 to $131600. However, the exact price depends on the type of battery used in the system. Although the price range is high, it’s still worth it in the long term.
