Many homeowners have considered adding backup battery storage to provide power at peak times or when the electricity goes out. Yet such an addition can be a major investment. Before you spend money on a residential battery storage system, consider these questions.
Why do you want a backup power system?
This is the first question an electric co-op’s energy advisor will ask. If you are concerned that your home is frequently losing power, co-op employees can investigate the
issue and identify potential fixes that may save you money. Sometimes you can resolve your issue without needing a more expensive purchase.
What do you want to power?
Battery systems that power an entire home are much more expensive than smaller systems that power critical items, such as heating and cooling, refrigerators, and a few appliances. The type of heating in the home can also make a huge difference; electric resistance heat requires much more electricity compared to a natural gas or propane furnace.
Before committing to a purchase, you need to understand what your backup battery system can do. Your cooperative can provide insight into the energy needed to power appliances and systems.
Have you checked on the support a contractor will provide?
A residential battery system will likely need a contractor to install it properly. Seek multiple bids and consider what each contractor is offering. Question each salesperson’s assumptions. Will a contractor provide a walkthrough on setup or support after installation? A good contractor should be willing to answer questions even after service is completed.
When you purchase a backup power system, be sure to follow your electric co-op’s interconnection rules when setting it up to ensure safe operation. This will prevent damage to your home and the energy grid and keep your co-op’s linemen safe.
By knowing the right questions and considerations, you can be sure that your backup battery system will meet your needs. Be sure to contact your local electric cooperative before you purchase a system to ensure the dollars you spend make sense!
