It has amazed us that since the load shedding started, so many people have been enquiring on the internet about what they can do. Questions about generators, UPS systems, inverters and so the list goes down. Our director published an article on his blog about generators, but since doing so we've learnt a great deal more and were advised that a generator might not be the best idea from a sound and current point of view. Because of this we started to investigate inverters and the lack of simple information around them. We were told that Outdoor Warehouse would be a good place to have a look - this after spending several hours trying to find somewhere in Cape Town to go to. A trip down to Outdoor Warehouse had us leaving with all the goods we need. Now, there's unfortunately a lot of technical information about all of this and we're digital marketers, not electricians but we'll try to share what we learnt. There are 3 components:
- An inverter (See the range we bought)
- A battery (See the range we bought)
- A battery charger (See the range we bought)
- If you run off desktops, you'll need a larger inverter because the electricity draw from a desktop is substantially higher and less reliable because a computer has it's own power supply.
- Remember to check what each piece of equipment in our office draws in watts - the sum of this shows the maximum concurrent wattage required and that's how you determine the size of inverter you require.
- Batteries are expensive because they're semi-deep cycle batteries, not high cycle car batteries.
- An inverter that is turned on draws current, so keep it off when you aren't experiencing load shedding.
