An IPS will allow your whole home to keep running on solar & batteries if the grid goes down, but you will experience a short period (a few seconds) where everything goes black or grey in your home as the backup system steps into gear. The next step down from a UPS is what we’ll term as ‘interruptible power supply’, or IPS. ‘Interruptible’ power supply (full home backup) Make sure you get them to clarify what they mean by ‘UPS’ before you purchase. Be cautious of sales people who refer to battery backup functionality as a UPS, because they may actually be referring to an interruptible power supply (see below). Most households do not require and are not willing to pay for this degree of dependability – unless they are operating critical medical equipment in the home. With a UPS, if the grid goes down, the lights within your home will probably not even flicker. This is the industrial-grade solution for backup power needs, often required by hospitals and industries with sensitive equipment whose uninterrupted operation is critical. These are: Uninterruptible power supply (UPS) (full home backup) There are roughly four approaches to home solar battery backups, although the difference may sometimes be fuzzy. The take-home point is this: If backup power is something that you want out of your battery storage system, make sure that you’ve received explicit confirmation from the company designing/installing your system that this is the case. Some solar inverters may allow you to tap into the the solar energy your panels are producing, but unless specifically included in your sales contract or other documentation, this is usually not the case.īecause of their history of use in off-grid power systems where there is no grid connection, many people incorrectly assume that all solar systems with batteries have backup power functionality, In fact, many battery storage products available in Australia do not provide backup support, or require a special inverter in order to provide it. Even for simple grid-connected solar PV systems, when the grid goes down, the power goes out – mainly for the safety of people working on the downed lines. We should firstly let our readers know that having batteries in your home does not necessarily mean having backup power functionality. Compare solar & battery storage quotes from installers in your area!Ĭompare Solar & Battery Quotes Not all home battery storage systems provide backup power In this article we take a look at the main approaches to battery storage that you’ll come across as you shop around for a system, as well as some of the considerations a shopper should keep in mind. Home battery storage is becoming increasingly popular in Australia, and one of the most in-demand features is backup power, which provides electricity to a home even when the grid is down.
