How do I know which model to use if I have 1 computer, Inkjet printer with 15" screen and a TV without dish and DVR/Video machine to keep on working for 8 hours if the power stays off for that long?
Answer: The INX500-5 model will do the job perfectly, provided that the above equipment does not exceed 200W. If the power comes back on after 8 hours, the system will charge the battery automatically within 4 hours and the system will be ready for the next power failure.

If you need less back-up time for the same equipment above, simply choose the model with 4 hours or 2 hours whatever your preference may be.

If you have 2 computers, 1 laserjet printer, 1 TV, satellite dish, and VCR/DVD, - not exceeding 400w, the INX1000 models are the range to use. Simply choose the back-up time you need in case of a power failure.

PS. We always recommend spare capacity of 1/3, so that the system do not overload if a surge occur.

Do you offer a warranty?
Yes, we offer a full 12 month carry in warranty on all units.

If I plug in too many electric devices, will the system overload?
Answer: The red overload light and buzzer will warn you immediately if you have too many devices plugged in. Simply unplug one or more devices until the warning light and buzzer stop.

What is the most practical way to use the power boxes?

Answer: Plug the input plug into your 220V wall socket. Plug your devices into the output plug provided. Switch the Inverex on - the green light will show if everything is OK. Leave the unit on permanently and use your equipment as normal - even when the power is on. The system will take care of the power failures and will switch over smoothly and automatically. Recharging is also automatically when the power comes back on. You've got nothing to do.

What does one do when a long power failure occurs?
Answer: Your plugged in equipment will carry on working for up to 8 hours automatically. Your equipment would not even know there is a power failure. In a household situation you would normally have a Cadac gas cylinder with a cooking top handy to prepare food and hot drinks and have rechargeable lamps and candles ready when it gets dark.

Do I really need a powerbox?
Answer: Eskom has warned that they are planning power cuts from May 2006 throughout the winter in most regions, especially in the Western Cape. This means that there might be power outages every day for 4 hours or longer for months. Yes you do need a Powerbox.
