What Is Home Battery Backup?

A home battery backup is a solar battery that can continue to power appliances during an outage. A decent system will also continue to collect energy from the solar panels so that the battery is not depleted immediately.

There are various levels of home battery backup. Consider the frequency and duration of blackouts in your area and which essential appliances you'd need to keep operating to determine which generator you'd need. You could get by with a standard battery if disruptions are uncommon in your area.

While a solar battery backup system would not necessarily allow you to live entirely off the grid, it could help power your essential appliances, such as your lighting, air conditioner, and refrigerator, in the event of a power outage.

What Are The Pros & Cons of Home Battery Backup?

The advantages and disadvantages of purchasing a home battery backup are reduced savings and backup power versus price.

The excess solar energy stored in your solar batteries can be used to replace the electricity you would typically purchase from your utility, or it can be sold back to the grid when its value is highest. This can save you money and alleviate some strain on the grid during peak demand. Whether this is feasible for you to save money depends on your utility's net metering policies.

Some companies are beginning to permit individuals to enroll their home battery backup in virtual power plants, a fleet of batteries, smart thermostats, and other domestic appliances collaborating to reduce grid demand. Virtual power facilities may provide the battery owner with additional benefits when available.

Additionally, you can use your battery bank if the utility goes down due to a failure, natural disaster, or solar flare. A backup generator, such as Jackery Solar Generators, can also help maintain power in an emergency and charge your batteries.

Batteries significantly increase the cost of a home's energy system, but federal tax credits and other incentive programs in Australia can typically be applied to the storage cost.

What Are The Types of Home Battery Backup?

Several types of batteries, including lithium-ion, lead-acid, and flow batteries, are used in home battery backup systems. Here is a summary.

Lithium-Ion Battery

On the market are a variety of lithium chemicals, including lithium polymer, lithium iron phosphate, and nickel-manganese-cobalt. The most recent lithium technology poses less fire risk than older headlines suggest.

They are capable of a deeper discharge than lead acid batteries, you can use up to 90 percent of a charge per cycle without causing significant damage, and they are much simpler to maintain and have a longer lifespan. Additionally, they are substantially more expensive and temperature-sensitive. However, they are becoming increasingly standard in home battery backup systems.

The Jackery Portable Power Stations utilize lithium-ion cell chemistry to store more solar energy and extend their lifespans effectively. In a power outage, a solar generator is preferable to batteries for powering domestic appliances.

- It can give several thousand charge-discharge cycles.
- It can be discharged heavily at 80 - 90% of its capacity.
- It is suitable for a wide range of ambient temperatures.
- It should last for 10+ years in everyday use.


- End-of-life may be a problem for large lithium batteries.
- They must be recycled to recover valuable metals and prevent hazardous waste disposal, but large-scale programs are still in their infancy. As lithium batteries for use in homes and automobiles become more prevalent, recycling processes are anticipated to improve.

Lead-Acid Battery

This technology has remained fundamentally unaltered for over a century. It continues to be inexpensive and broadly accessible. Famous for use in solar systems are more costly sealed batteries requiring less maintenance and eliminating the danger of acid spills and hydrogen off-gassing. Initially, hermetic lead acid batteries appeared to represent the future of solar batteries.

However, all lead acid batteries require more cautious monitoring of charge levels than lithium-ion batteries and cannot compete with lithium-ion batteries in terms of efficiency, energy, and lifespan. Still, they are a cheap and abundant alternative.  


- It is relatively cheap, with established disposal and recycling processes.


- It is bulky and requires much more space than an equivalent lithium battery.

- It is sensitive to high ambient temperatures, which can shorten its lifespan.
- It has a slow charge cycle.
- It requires regular maintenance.
- It has a shorter warranty.

Flow Battery

Due to their commercial design, Flow or redox flow batteries are less common in residential systems. However, the technology appears promising and may be utilized more frequently shortly in hone battery backup systems.

This type of battery, one of the most promising alternatives to lithium-ion, employs a pumped electrolyte, such as vanadium ions or zinc bromide, and chemical reactions to store and release charge. Red flow battery is presently the most popular flow battery in Australia.


- It can be discharged to 100% of its capacity and has no residual discharge so that it won't lose charge over time.

- It keeps capacity over time.
- It operates well in high ambient temperatures.
- It is relatively easy to recycle.
- It should last for 10+ years.

- Being a new technology, it is relatively expensive compared to lithium-ion.
- It doesn't tolerate cold well (below 15°C).
- It requires frequent maintenance, which takes it temporarily out of service.

How Does A Home Battery Backup Work?

The concept of home battery backup isn't novel. Battery storage has been employed considerably in off-grid solar photovoltaic (PV) and wind electricity generation systems on isolated properties to store surplus electricity for future consumption. Most residences with solar panels will have a battery system within the next five to ten years.

how home battery backup works
A battery stores any excess solar energy generated during the day for use at night and on days with insufficient sunlight. Installing batteries is becoming increasingly popular. There is a strong desire to be as independent of the grid as possible; for most people, this is not only a financial decision but also an environmental one; for others, it is an expression of their desire to be independent of utilities.

If your solar panels and battery are large enough, you can operate a substantial portion of your house on solar power. Depending on the time of day and electricity rates in your location, it may be cheaper per kilowatt-hour to use electricity from your battery than from the grid.

How Does A Jackery Solar Generator Work?

Jackery Solar Generators are straightforward solar-powered charging devices. Establishing a connection between Portable Power Stations and Jackery Solar Panels and positioning them in direct sunlight facilitates the conversion of solar energy into electrical power. 

The electrical energy is converted into a suitable format using an inverter inside the power station to power electronic devices.

how Jackery solar generator works

The Jackery Solar Generators are built and designed to emphasize ease of use. The only requirement is connecting the Jackery Solar Panels to the Portable Power Stations. Solar panels generate electricity when subjected to sunlight. 

The solar charging line enables the transmission of electrical energy to Portable Power Stations, where it is converted into a form that can power various devices. The excess electricity generated will be retained on-site.

Connect the Portable Power Stations to the electronic device to charge or use. Automatic energy transfer will occur between the power facility and your device. The entire procedure is straightforward.

How Much Power Do You Need for Home?

Examine the batteries' capacity first to ensure that your home battery backup system meets your power requirements. Typically, this capacity is measured in kilowatt-hours (kWh).  

In addition, you should measure the surge current requirements of the devices you wish to power, particularly if you plan to start a motor, such as a sump pump. Powering high-demand appliances such as pool filtration or air conditioning units with a battery system for extended periods may not be possible.

Cost is an essential consideration when designing a battery system. If your energy needs are at most 15 kilowatt-hours of inverter power or 30 kilowatt-hours per day for your batteries, the system's price may become prohibitive.

In addition, it is essential to consider potential inefficiencies, voltage fluctuations, and other losses to ensure that your system can handle any conceivable situation. Considering all these elements, you can design a battery system that satisfies your requirements within your budget constraints.

What Are The Home Battery Backup Levels?

Solar Quotes created descriptions of the various levels of battery capabilities in response to past confusion surrounding home battery backup. Briefly, these are the four levels:

Level 0: Zero backup capabilities exist. You and your neighbors will be in the same position in an outage.

Level 1: Some backup, but with diminished battery power.

Level 2: It provides backup with full functionality; however, solar panels on the roof cannot charge the battery system during an outage.

Level 3: You possess full battery functionality and can recharge your batteries using solar panels when the power grid is non-operational.

But even with an energy storage solution capable of "Level 3" backup, it must be implemented and utilized cautiously. Whole-house backup can be problematic if you are unaware of a blackout and continue to use electricity as usual, draining the battery quicker than it usually would.

How to Choose The Best Home Battery Backup?

Consider the following factors when selecting the best home battery backup:

Power Consumption: The size of your home and the number of appliances you must keep operating during a blackout will influence your decision regarding the optimal solution. Setting up off-grid power for a tiny house may necessitate a different answer than setting up power for a large residence with various appliances. Your home's energy consumption will determine the power output and storage required to keep it operational during a power outage.

Power Outage Duration: The length of a blackout should also weigh heavily on your purchasing decision. What you need for a one-day blackout varies significantly from what you need for a week.

Depth of Discharge: This is the percentage of energy that can be used safely without accelerating the battery's degeneration. Most battery varieties must maintain a charge at all times to prevent damage. 80–90% of a lithium battery's nominal capacity can be safely discharged without compromising safety. Lead-acid batteries can typically be discharged to about 55–65%, while flow batteries can be discharged 100%.

Capacity: The battery's energy storage capacity is usually measured in kilowatt-hours (kWh). The nominal capacity is the complete amount of energy the battery can store. In contrast, the usable capacity is the amount that can be used after the depth of discharge is considered.

How to Set Up The Best Home Battery Backup?

Constructing a home battery backup system takes more than just a battery and some cables. You must attach the battery to the electrical panel and ensure that all system components, including the home backup batteries, inverter, charge controller, and wiring, are compatible.

Step 1: Find A Power Inverter

Your household appliances are powered by alternating current electricity. Batteries, unfortunately, generate direct currents. You cannot connect a battery directly to your residence's circuit board or appliances. The battery power must be converted into AC or household electricity. Inverter refers to the device that converts DC power to AC electricity.

Step 2: Choose A Battery

Next, you must select your battery. You will likely need multiple batteries for a backup power supply for the entire residence. There are batteries with capacities ranging from 100Wh to 3.6kWh, which are suitable for powering large appliances. Determine the power output and storage capacity required by calculating the wattage requirements of the machines or devices you wish to power.   

Step 3: Need A Charge Controller

Next, you need a battery-charging component. A charger and a regulator can recharge batteries without overcharging. Perilously. Element. Ensure that your charger is compatible with your batteries to avoid damaging them.

Step 4: Connect The System

Finally, you must connect your components via wiring. Connect the battery to the inverter, the charge controller, and the charging source. Establishing a connection through a transfer switch is necessary to integrate a home battery backup system with the existing circuitry.

Final Thoughts

You and your family may be in jeopardy during a power outage if you do not have a home battery backup system. Traditional fossil fuel generators can be kept on standby for power outages. However, gasoline and diesel generators waste fuel, emit harmful emissions, and are extremely loud, not to mention detrimental to the environment. What is a more sustainable alternative? Jackery Solar Generators could incorporate solar panels and lithium-ion battery power stations to maximize solar energy usage.
