How to Extend UPS & Power Inverter Backup

– Use energy saving devices.
– Turn off extra devices or appliances if not in use.
– Connect bigger or more batteries to your UPS / Power Inverter.
– Change old and worn out batteries.

People use power backup devices to cope with power outages that are caused by either bad weathers or scheduled load shedding. UPS (uninterrupted power supply) and Power Inverter are two commonly used electric power backup devices that are capable of supplying electric current to keep electrical and electronic devices working. Their use varies from running computer servers, fans, lighting and all sorts of home appliances. Computer servers no matter they are larger for commercial use or smaller for official or residential use, they are always connected with UPS to protect their running activity and keep them always online in case of power failure. A standby generator is also always kept ready in case of extended power outage or black out.

There is a small difference between a UPS and a Power Inverter. UPS carries built in batteries packed inside the enclosure for a limited supply of backup. Whereas Power inverter can be connected with a wide sizes of batteries or battery banks depending upon the needs. Before buying a UPS or power inverter, you should calculate how much backup you need. Then a purchase should be made. Below are some useful guidelines and tips to increase the backup of your power backup device.

1- If you own a smaller UPS or Power Inverter with smaller battery, the backup time will be shorter. What you can do is decrease your average power consumption by disconnecting or turning off extra load when not needed. More the load you put, more the power will be sucked out of batteries and shorter will be the backup period. So, try to manage your needs to extend the backup.

2- UPS that contains built in batteries can be opened and connected with larger external batteries as well. Make sure you buy similar voltage batteries made with similar chemistry as that of UPS’ built in batteries. Power inverters can be connected easily with larger batteries without any hassle. Additionally, by connecting several batteries in series-parallel, larger battery packs can be made which can be used to extend the backup.

3- Use energy saving devices only. Ordinary bulbs consume 75 % more electricity but gives the similar brightness as CFL lamps give. To further cut the load, use LED lights. LEDs are the most energy saving light producing devices which are now widely used due to the low power consumption and extremely long service life. Newer fans made with better copper winding also consumes lesser power. Poor quality wiring increases the resistance thus increasing the load on UPS and affects the backup. Use good quality copper wires only.

4- Latest gadgets consume fairly lesser electricity than older gadgets. New LED televisions, computer monitors and new technology based CPUs, they all consume very low power. Servers should be upgraded for efficiency and power saving. The use of SSDs inside them can further cut the load. UPS in which larger batteries can not be installed, such upgradation can help or you may go for a larger UPS instead.

5- Change the batteries if they are worn out. Batteries lose their designed capacity over time thus reducing the backup. Buy good quality batteries only which will last longer and also guarantee the correct charge storage capacity. Poor quality batteries fails prematurely, does not offer better backup, and are simply waste of money. SLA batteries (sealed batteries) are best suited for installing inside the enclosure as these won’t leak the electrolyte. Power inverters can be connected with flooded lead acid batteries as well. There are other types of batteries as well like lithium batteries which can be used if the Power Inverter or UPS manufacturer recommends their use. Lithium (ion and polymer) batteries are the most efficient batteries available today in reasonable price.
