What To Consider When Buying a Backup Power Supply for Your Home
There are a lot of things that go into choosing the right backup power supply for your needs.
Below, we’ve compiled a list of some things to remember while selecting your ideal backup power supply for your home.
Capacity
The capacity of your power supply refers to how much power storage it has. If you’re trying to run more power-hungry appliances or get through a longer outage (or both), you’ll likely want a backup option with a higher capacity. However, if you’re just looking to keep some personal devices charged, you’ll probably be able to get away with an option with a lower capacity.
Max Load
Regardless of what capacity your backup power supply has, you need to make sure that it’s capable of running the devices you hope to power. Not all backup power solutions will be equipped to handle heavy-duty appliances such as your dryer or refrigerator. Look at the AC output your backup power supply can handle and compare it to the devices you want to power with it. Depending on the power solution you choose, you may not be able to power all of your devices simultaneously (or at all).
Expected Length of Outages
How long do you need your power supply to last? Are you trying to have a backup power supply for outages that last a few hours, or are you preparing for something that could last days or even longer? When investing in a home backup power supply, it’s essential to consider how long you’ll likely need to power your home and budget accordingly.
Cycle Life
The cycle life of a battery refers to how many charge and discharge cycles you can expect before a decrease in performance. Consider this when comparing options, especially if you’re looking for a solution that will last years.
Charging Options
How are you going to charge your backup power solution? Different charging options are available depending on what you choose. Consider what charging options you’ll have available to you. Power solutions that support solar charging allow you to recharge with the proper gear even during a grid failure – and be eco-friendly simultaneously!
Budget
After weighing the factors above, it’s crucial to tailor your budget to ensure your investment into a backup power supply for your home is worthwhile. More powerful and robust backup solutions typically come with a higher cost, but there are often tax credits and incentives you should consider. A backup power supply for the home is a substantial investment, so doing your homework to understand where your budget needs to be is a must.
Frequently Asked Questions
The right backup supply depends on your home’s electricity requirements and finding the best power supply option to meet those energy requirements. Consider factors like capacity, AC output, charging options, and more when deciding on the right option for you.
Different homes benefit from different power backup solutions depending on their goals, power needs, and budget. The EcoFlow DELTA Pro Portable Power Station offers an expandable capacity of 3.6-25kWh, but some homes won’t require such a robust solution.
Final Thoughts
A reliable backup power source is important if you want to keep the lights on and your appliances running as usual in your household. To find the right option, you need to consider factors like capacity, AC output, cycle life, length of outages you want to be prepared for, and more.
