Load shedding is here to stay, it is not going anywhere – for several years!

Eskom might be downplaying the severity of their problems, but at the same time have informed us that load-shedding is here to stay for some time!

An inverter provides “power in a box” solution to power computers, laptops, TVs, radios and lights for several hours.

Just plug it in!

When power is available, it keeps a battery charged, which is then used to continue powering electrical devices during a power outage.

The inverter has a number of power plugs to connect your electrical equipment into it without fuss.

Good for: Computers and laptops, Monitors and TVs, HiFi and bluetooth speakers, Smart phones and smart devices, Lights

Not for: Fans and motors; Compressors, aircons, fridges

2400VA 1440W trolley inverter

This inverter powers equipment up to 1440W.

These inverters are modified sine-wave inverters and are not recommended for all appliances. These inverters are only recommended for use with standard IT and electrical devices, but not for sensitive devices (such as medical devices), compressors or motors.

Ideal for:

Not recommended for:

  • Motors
  • Fans
  • Fridges
  • Air conditioners
  • Medical devices

What you need:

Need a cheaper solution? Don’t need 1440Watts?
Also available in 720Watts.

What you need:

Need the best value for money? Don’t need a fancy enclosure?
Both 720W and 1440W are available without the trolley enclosure.


You can save by buying the “open-air” inverter if you have a hiding place for the inverter and battery (cupboards must have enough space for air flow).

What you need:

  • Mecer 1200VA 720W inverter (Buy now)
    Requires 1x 100Ah batteries (Buy now)
  • Mecer 2400VA 1440W inverter (Buy now)
    Requires 2x 100Ah batteries (Buy now)


Inverters offers a long run time (several hours) compared to UPS (5 to 10 minutes)

A UPS is used to keep a computer running for several minutes while the generator starts up (5 to 10 minutes). A UPS will beep continuously when power is off.

An inverter will run for hours and does not beep continuously. It will signal when power fails, when power is restored and when battery is low.

A UPS is cheaper to buy than an inverter.
UPS batteries have a short life span if there are regular power failures, but the batteries are cheaper to replace than inverter deep cycle batteries – usually one or more 12V 7Ah (12V 9Ah)

Neither UPS or inverter are absolutely silent, they have fans that cool the system down when running from the battery.

Maximum run times at different power, and different battery capacities

*run times vary with type of battery, age of battery, ambient & battery temperature, and rate of discharge, inverter efficiency, maximum battery discharge. Example: Note how the amount of power supplied by the same battery drops at higher currents: 10 hour rate (10.0A, 10.8V) = 100Ah. 5 hour rate (17.5A, 10.5V) = 87.5Ah
