We have all experienced the frustration of a power outage, or load shedding when we desperately need our laptop to be powered, or to finish cooking a meal.

Backup systems have become the go-to for the average user who doesn’t have access to an alternative power source. But with all of these products available, how do you know which to choose? Take a look at our overview to help you decide.

What is the difference between a home long backup system and a UPS system?

The purpose of a UPS system is to be a powered backup for sensitive equipment like servers, computers, medical equipment, telecommunications equipment, etc.

A standard UPS system has small internal battery sets that provide a short backup time of approximately 5 – 10 minutes, which only caters for the internal battery sets they were designed for. Additional or external batteries cannot be connected to boost these systems.

There is the long backup UPS system available which can be supplied with external battery sets that are able to power for about 2 hours. A system can be intentionally oversized to cater for a longer powered time, for example 4 – 6 hours.

The double conversion online UPS systems have no break whatsoever in power. The equipment is fairly sensitive and will always run on electronically produced power as a constant supply, and is not directly connected to the mains power.

In contrast to the UPS system, the inverter based long backup systems do have a small break in connection when they change to the backup power (regardless of brand or model).

The higher quality systems, which Bundu NetworX supplies, switch over within a fraction of the time previously experienced. These inverter systems incorporate larger battery chargers which means larger battery sets can be installed resulting in much longer backup times than UPS systems.

The home long backup systems do have a small break in connection when they switch over to backup power (irrespective if the inverter system, but the good quality systems power break is almost imperceivable). These systems incorporate large battery chargers which means that extra large battery sets are installed, resulting in extra long back-up times. This is just not feasible with UPS systems.

What do you need?

Firstly, make a list of exactly what appliances you want to provide backup power for.

You will need to take note of the appliance ratings in Watts, Amps or VA (this is usually stated on the back of the appliance on a label or in the manual). When you have these power ratings, total them to come to a combined rating.

You can then look at the different backup times required and provided by a particular unit to meet your needs. Please contact us for pricing and availability.

You can connect the following appliances to the inverter systems as long as the total power consumption does not exceed the maximum wattage rating of the unit:

  • Small to large Plasma or LCD TV
  • DSTV and MNet decoders
  • Surround sound systems
  • 5 to 10 energy saver lights
  • Fan
  • Fridge and deep freezer
  • Home alarm system
  • Automatic garage door motor
  • Intercom
  • Electric fence
  • Microwave oven
  • Small kettle
  • Fax machine
  • some standard home power tools.

Try to avoid connecting the following ‘power hungry’ items:

  • Geysers
  • Underfloor heating
  • Stoves
  • Air conditioners
  • Washing machines
  • Tumble driers
  • Dishwashers
  • Pool pumps.

The bigger inverter systems (5kW, 6kW, 8kW and 10kW systems) are able to run the more ‘power hungry’ items. Some of the more sophisticated systems are also available in three phase up to 72kVA.
