UNDERSTANDING HOW TO SELECT THE CORRECT INVERTER.

What Warranty Do I Get on My Purchase?
The inverter or UPS is guaranteed 1 year, under the condition that it is un tampered with.Due to the quantity and duration of power outages experienced at present we have had to change our warranty policy for batteries. Basically if the customer has used up the cycle life of the battery within any part of the standard 12month warranty period then we do not replace the battery under warranty, if the battery is defective, if there is a manufacturer defect the battery will be replaced under the 12 month warranty

What system do I need?

If you would prefer some professional advice please contact us via email or telephone. If you would like to work it out yourself you need to look at your situation and make some decisions on what equipment you need backup for. Some people want EVERYTHING to work, some are happy with their TV, DSTV and a couple of lamps.

Ask yourself the following question to decide which range and size you require;

a) What kind of System do I Want?

Do I want the Plug and Play option which I can directly plug my appliances into? The alternative is a larger Inverter and battery bank that you can have installed to your distribution board by an electrician. This can then supply backup power to certain parts of the house.

b) How many watts do I need to provide for in total?

Decide what equipment you wish to have backup for e.g. TV, Decoder, 2 Lamps etc.. then add up how many watts each item uses. Most electronic items will have the watts (or amps) printed on the back or within the manual. If not, you can consult the generalised table for guidance. If you have the amps, simply multiply by 240 to get the watts. If you have a number with a ‘VA’ – this is the same as watts.

Be aware that many types of equipment have a peak/surge requirement. For Example, TVs can require up to 3 times their normal requirement to start up. This peak requirement should be considered when calculating backup size. Consult the General Power Requirement Table for guidelines.

c) How long do I want this backup to last for?

You need to aim to have an hour or two longer than the average power cut. This will ensure your batteries have a good lifespan and it will also give you that extra backup for when you need it. You can consult the backup time table to work out what you need. Remember that a TV that needs 300W to startup may only draw about 100W thereafter. A PC that needs 200W-300W to startup may only use 100w-150w thereafter. Therefore you should consider the average draw when calculating backup time.

How long will the backup last for?
Consult the backup time table to workout backup times.

What about installation?

Inverex Inverter
The Inverex needs to be connected with a battery or batteries as well as with the equipment you wish to run. This takes some know how to connect but most men would manage this connection fine. The cables are included. You may need to use an adaptor to plug into the unit as the socket is the universal type. If you would like to connect more than one item to the unit you will need a multiple adaptor (just like you need when you have only one wall socket). For lights, you can plug in lamps.

You can also have the Inverex connected to your distribution board. This must be done by a suitably experienced and qualified electrician. This will allow you to have backup for your built in lights.

Kema Inverter
The Kema must be connected to your distribution board. This must be done by a suitably experienced and qualified electrician. Your electrician will discuss with you which sockets and lights to backup in your home / office and set it up accordingly. You will need to have a suitable area to mount the inverter and store the battery bank
