How To Choose the Best Household Battery Energy Storage

Technician installing renewable energy system

The home-based renewable energy system is rapidly transforming the energy market, providing usable and affordable energy for most homes and eradicating the challenge of energy generation and load distribution. With the current rise in energy consumption, homes are constantly seeking eco-friendly, cost-effective, and stable power supply alternatives that can satisfy their electricity needs. This state-of-the-art storage technology helps to store energy from renewable sources like wind, hydro, biomass, and solar, then converts it to usable power during grid outages

The global market for battery energy storage systems is expected to grow at a robust CAGR of 26%, moving from US$ 3.54 billion in 2021 to US$ 44.86 billion by 2032. The increasing demand for dependable energy supply and grid battery storage by end-users proves there is a market opportunity for battery storage systems.

Why are household batteries in hot demand?

      The concept of energy storage systems has paved the way for the generation and storage of excess energy, which is then reused during blackouts. This energy is absorbed from solar panels when the sun has high intensity (daytime) and used when the sun has a poor intensity (nighttime). Ultimately, the collection of generated energy from renewable energy sources has helped ensure reduced power disruption, especially in developing countries, and on the other hand, shrinking the environmental footprint.

      Household batteries are particularly in hot demand due to their affordability and environmental friendliness and are likely going to dominate the mainstream market in the next 10-20 years. Statistically speaking, the global battery energy storage market size rose to US$ 10.88 billion in 2022 and is predicted to reach US$ 31.20 billion by 2029, exhibiting a CAGR of 16.3% during the forecast period. 

Key things to consider before choosing a household battery

The business of picking the right type of energy storage battery is a tricky one. Not all storage systems have the design to scale a business. However, with the understated factors, it is possible to assimilate the type of batteries customers want and use that scope as a strategic resource for competitive advantage.

Battery cost

The Kwh battery cost is a crucial factor when deciding which battery to go for. Consumers prefer budget-friendly energy storage alternatives that are self-sufficient, eco-friendly, and effective. To satisfy consumers’ huge demands, measures must be taken to ensure the purchased batteries possess the design and capability to deliver the needed results. Most less expensive battery options rarely come with high storage capacity. Some of them come with a reduced warranty, and in some cases, lack after-sales support. These limitations have to be duly considered when deciding which battery to go for.

Storage capacity 

Load carriage is a factor not to be overlooked when searching for battery energy storage systems. Consumers often express readiness to acquire batteries that can carry critical loads in the house. For example, an 8kW inverter will not be able to power a 10kW air conditioner unit, regardless of whether the unit only consumes 3kW during normal operation. Using low-capacity inverters to power high-capacity equipment means machines reaching 10kW of power, which could spell disaster in the future.

A good way to manage power overload issues is by opting for an inverter that can bear loads of high-capacity devices in the house, rather than getting an option that should bear the load of the whole house power. 

Environmental rating

Battery life can be shortened when it is exposed to a bad environment. Batteries are generally affected by moisture, high temperatures, and dust. Some heavy battery electric storage systems are sometimes found outside the house, where they might be exposed to rainfall or water splashes. In conditions where it is necessary to position a battery outside of the house, be sure to build a sizable house, with good ventilation, for the battery. Conducting a thorough environmental check before moving an inverter to its designated home is crucial, and it is also the installer’s job to ensure the battery energy storage system is fixed properly at a suitable location. But batteries with the IP65 rating can be placed anywhere since they can tolerate direct water spray and dusty atmospheres. 

Battery energy efficiency 

To make the most out of a battery energy storage system, learn about its efficiency and capacities. Lead acid batteries have very low efficiency, so more expenses are used to manage their daily cycle. Lithium batteries have an improved technological makeup that enhances their efficiency, although this type of battery can self-discharge at the rate range of 1.5–2% per month (the rate can also increase based on temperature conditions and how they are charged). Note that battery efficiency does not count for off-grid systems, since they operate differently and require a huge amount of energy generation and storage capacity to function efficiently.

Lithium solar battery

This lithium solar battery is a rechargeable energy storage system that can be recharged by the solar panel, thereby enabling the absorption and storage of excess solar power. It supports parallel connection (up to 5 systems). It is vibration friendly, with a secure and comparable design that accommodates ports (for external connection), switches, and other keys.

Its application is vast, but the most common are in wind systems, solar systems, telecom, UPS, emergency lights, and solar lights.
