Hi all,
We are experiencing a shortage of generators as well.
Staying in a rural area, things are worse than in the cities.We get shedded more often than you guys.
On thursday we had 5 outages lasting from 2 to 3 hours at a time.
There is a solution:
Get a 12 volt deep cycle Delco battery and an inverter(3000)watts.
The inverter changes 12 volt into 220 volt.
Make an extention (electricity cable)with a 3 point plug attached to both ends.
Switch the main power to the house off at the DB board.
Also switch off the geyser.
Plug one three point plug of the extention into the inverter.
Plug the other three point plug into any convenient plug box.
Switch on the plugbox and the inverter.
Now you have 220 volt power to all your plugs in the house as well as power for your lights.
All appliances,like tv,fridges,computors etc will work.
Toasters, electric kettles and your geysers won't work.
An electric kettle uses 3000 watts,same with a geyser.
When the power comes back on 4 or 5 hours later all you do is disconnect the inverter,put the battery on charge,switch the mains back on and switch the geyser on as well.
Reason you have to switch the mains off before you start the inverter is:if you don't switch it off you will supply the national grid and your stuff wont work.
The second reason you have to turn the mains off,is when the power comes back on you will blow up your converter and your deep cell battery.
A Delco deep cell battery costs about R 1200.
A3000 watt inverter shouldn't cost more than R 1500
A 12 volt 6 amp batterycharger would cost about R 200
If you really want to go way out you can get yourself a solar cell 55 watt to charge the battery.
