There are still many places and areas which still experience frequent power outages. That is why many customers are considering buying a UPS for their homes. UPS’s have proven to be compatible with generally all the electrical appliances that you would find in an average household, so it further reinforces this choice.
There are different types of UPS available in the market. One needs to pick the one that meets the user’s criteria. With that in mind, the best UPS options for household use would be identified.
The Best Option For Household Use Is An Offline UPS.
As the name suggests, there is no constant current flow during its normal operation, except a trickle charge for battery maintenance which means it uses a switching mechanism for transitioning to a backup power source. The benefit of this approach is that it lowers the electricity consumption of the UPS and creates a cost-effective setup.
Its potential downside that it takes a period of time (usually around 5ms) for the switchover. Usually this is not a problem because nearly all appliances can tolerate it without creating any problems.
That being said, other types of UPS can be considered if the house faces a unique situation. For instance, if the house is located in an area that experiences many fluctuations in power supply then a Line-Interactive UPS can be considered as well. It is more expensive but offers protection against varying voltage inputs through its voltage boost circuitry.
Similarly, there are some houses that have extremely sensitive electronics too. This is a possibility where a person may have an electronics lab at home or there is a stay-at-home patient who needs monitoring equipment. In both cases given the criticality of the situation, it may be wise to invest in an online UPS. It is a more expensive option but with its continuous flow of current, it has no switchover time.
It is also vital to remember that the battery is a “use it or lose it” asset, which degrades over time, and when there is no load-shedding, the system should be allowed to run until flat then re-charged once a month in order to prolong battery life,
as batteries become Sulphated and fail when left unused on Float charge for long periods and if batteries fail under conditions of non-usage, this is not a factory fault and therefore not covered under warranty.
Running the system occasionally also gives you advance warning of battery capacity loss over time, and whether your system is still functioning properly.
