Inverters
What system do I need to keep my lights on during load shedding?
DECIDE WHAT APPLIANCES YOU WOULD LIKE TO POWER
The wattage given below are estimates on essential appliances
CHOOSE AN INVERTER THAT CAN HANDLE THE COMBINED WATTAGE OF YOUR DEVICES
Some appliances draw double (2x) it’s power during start-up (surge power)
Example 1
Start-up power surge: 575w
Continuous Power: 280w
Example 1
Start-up power surge: 384w
Continuous Power: 192w
An inverter needs a safety margin of about 10-20% when it’s operating.
Never load the inverter @ 100% (full) capacity.
HOW LONG WILL I HAVE POWER FOR DURING LOAD SHEDDING?
Depends primarily on how powerful the appliance(s) you’re running & if the battery is fully charged.
Lead-Acid, GEL and AGM batteries should never be fully discharged and can only be discharged up to 50% before irreversible damage occurs. This means that you will only be able to use half of your battery capacity.
HOW TO CALCULATE THE HOURS
Example
50% x 12V = 600
150W (TV) + 50W (DSTV) + 7W (LED LIGHT) = 207
600 + 207 = 2.89 hours

WHAT APPLIANCES TO LOAD ON OUR INVERTER RANGE
The wattage given below are estimates on general appliances. Check your appliances to determine the actual wattage. Makes & Models can drastically alter the wattage.
• Newer appliances use up less energy.
• Please view the wattage on your appliance for 100% accuracy.
• The largest electricity consumer in the average household is your heating and cooling appliances.
• Depending on how powerful the appliance/s you’re running & if the battery is fully charged.
