Are Battery Backups Worth It?

If you live in extreme weather conditions or places with frequent power outages, it is necessary to have some backup power source. Most of the time, people have been using fuel-powered generators, the dominant backup power supply in the market. But the increased risk of carbon monoxide poisoning has done our search for safer alternatives.

With the introduction of backup batteries for home use, generators have become less popular and functional because of the advantages that batteries offer. Battery backups are undoubtedly a safer and more eco-friendly option as compared to traditional generators. Even though generators and solar battery backups serve the same purpose, they cannot be referred to as the same or similar devices.

Backup batteries for home solar are indeed more expensive than conventional generators, but they ensure that there is no greenhouse gas emission. They also provide sufficient energy during power outages and the night if your solar panels are not charged enough.

Which Battery is best for home backup?

The backup batteries we use in our homes typically have one of the three chemical compositions: lithium-ion, lead acid, and salt water. Lithium-ion batteries are one of the most popular and effective options in most cases and are the best backup batteries for homes with solar panel systems. The only drawback of lithium-ion batteries is that they are more expensive than all the other types of batteries.

The lithium-ion batteries are the best option because they are lighter and more compact than any other battery. Moreover, in modern technology, various forms of lithium-ion chemical composition are used in most of the latest home energy storage technologies. Moreover, lithium-ion batteries have a longer lifespan and a higher DoD.

If you cannot afford lithium-ion batteries, you can also consider getting lead-acid batteries, as it is the cheapest solar battery. These batteries are also a tested technology used in off-grid energy systems for quite some time. Lead acid batteries have a shorter lifespan and a lower DoD than lithium-ion batteries and other types of batteries, but they are also the cheapest option. So, if you are planning on going off-grid and need to install a lot of energy storage at your home, you can consider installing lead-acid batteries.

The home energy storage industry has also introduced saltwater batteries. These batteries do not use heavy metals like the other battery options. Instead, they rely on saltwater electrolytes. Therefore, lithium-ion and lead acid batteries must be disposed of through unique processes, but saltwater batteries can be easily recycled. One of the significant drawbacks of saltwater batteries is that they are relatively untested, and the only company producing them filed for bankruptcy in 2017.


How long can a Battery Backup Power a House?

Once you have installed a battery backup at your place, you will not have to worry about the power supply in case of a power outage 0r a blackout. If you have installed a solar panel system at your home, you will have to ensure that there is a battery backup for when your solar panel system is not charged enough. The battery backup will provide your home appliances and devices in case of low charging of solar panels or during power outages.

The power the battery backup will supply your place depends entirely on the battery’s capacity. The capacity of batteries is measured in kilowatt-hours and can vary from 1 kWh to greater than 10 kWh. If you want more backup batteries, you can install multiple batteries at your place. But a 10 kWh battery backup is enough for most homes, and this is what most homeowners install.

If you have a power outage or a low solar panel, you can use all the energy if your battery backup is fully charged. You will not be able to use 5 – 10%, but that is relatively insignificant, and it is due to the chemical composition of these batteries. Different electrical appliances use an additional amount of power or energy. Therefore, if your whole house is entirely working on the battery backup, you must use the power wisely. The more appliances you will use, the quicker battery backup will drain.

You can use everything on the battery backups, from refrigerators to air conditioners but make sure to utilize energy in a calculated way so that you don’t have to sit in the dark without your AC or heating system once the backup battery’s charging is finished. Your refrigerator uses 1 – 2 kWh per day, and this energy can be reduced by opening the refrigerator door less and increasing the temperature slightly.

Moreover, your air conditioner uses 270 kWh of electricity per month if you use it for six hours daily. This means that it uses 1.5 kWh of electricity per hour. So, it is always suggested not to use an AC during a power outage or low solar panel energy, but you always have the option to use it if you think the required point will be back soon. The water heating appliances also use a lot of electricity, approximately 162 kWh per month. So, if your water heater runs for two to three hours daily, it will take up almost 5 kWh.

The appliances like lights and chargers of your smartphones and laptops take up less energy. But even though they take up less energy, you should use the energy wisely when your appliances are working on emergency battery backup power. So, suppose you have a typical 10 kWh backup battery like most homeowners. In that case, you can quickly go a whole day without your solar panel or electricity if you use the appliances you direly need and go without the ones that are not as necessary.

How can we solve the Power Outage Problem?

You don’t experience power outages daily. Mostly, the electrical appliances at your homes and factories keep on running, and the electrical power is flowing. But there are some occasions when there are power outages, everything goes black, and all the working electrical appliances are shut down. Some power outages can end as soon as they start, but some last longer and might cause many inconveniences. Usually, power outages occur due to extreme weather conditions like freezing rains, snowstorms, heat waves, and high winds.

During a power outage, you will have to face serious challenges. It will leave you in the dark, and all your electrical appliances, including heating and cooling systems, will also be turned off. Therefore, taking the necessary measures to prepare yourself for power outages is vital. Even if you are off-grid and have a solar panel system installed at your home, you will still have to be prepared to deal with complete blackouts. This is because solar panels might not be charged if there is no sun for days.

Here is a good guide for preparing yourself for future power outages.

1. Be Aware of the Risks and Be Prepared

The first thing that you will have to do is to be aware of the risks that might come with the power outage and be prepared for it. You must be mindful of the risks specific to your community and your region to prepare beforehand. Firstly, you will have to prepare your house for a power outage. Whether off-grid or on-grid, it is always a better option to back up batteries. You will not regret getting a solar battery backup system for your home.

Moreover, it is also recommended to install a stove or a heater that doesn’t work on electricity. Also, if you have a family member with disabilities, you must provide them with the necessary assistance during the power outage. You must prepare medical conditions, treatments, and essential electrical equipment lists. Also, make sure to have a flashlight or a smartphone at arm’s length, so you are not entirely left in the dark.

During a power outage, ensure that it is not only your place going through the blackout. The next step is to complain to the power supply authority. Make sure to turn off all the electric appliances because there is more chance of quick restoration if there is less load on the electrical system.


2. Make an Emergency Plan

The safest option is to have an emergency plan in all cases. You cannot ignore that your family might not be together during a power outage. So, it is essential to discuss with your family what will happen if there is a power outage when they are in school, at home, or at the workplace.

On top of it, make a list of what needs to be done ahead of time. It is vital to store all your necessary documents in waterproof containers. Also, you must have an out-of-town emergency contact you can visit in case of emergency.

Make sure to go over this plan every year with your family and make changes if necessary. You never know when the emergency will occur; therefore, you must be ready for anything, no matter where you are or what time it is.

3. Make Your Emergency Kit

It is essential to have an emergency kit ready at all times. Your emergency kit must have all the essentials, from flashlights to water and basic medicines. The key to making the perfect emergency kit is to write all the requirements down and see what you cannot go a day without.

Make sure that your emergency kit is easy to carry. You can consider using a duffel bag or a suitcase with wheels to take it as soon as possible and leave when needed.

Moreover, your emergency kit should be anywhere near your house’s exit. You will not want to hurry to the attic and get out your emergency kit when there is a power outage, and you cannot even see anything. So, make sure that it is easy to reach and easily accessible.
