DC-AC power inverters for the office environment. There is often a need for emergency power back up for critical appliances such as:

• Computers
• Printers
• Scanners
• Switchboards
• Mobile telephones
• Lighting

For most businesses it is critical to have an office power back up solution in place - a power outage means loss of revenue and potential sales!!

Both modified sine wave power inverters and true sine power inverters have derivatives that include a generator transfer switch. Some are specifically designed to operate with a generator or interruptive power source. In other words, these inverters are ideal where other means for charging the batteries is available from either solar panels or external battery chargers. Obviously in the office environment, most likely there will be a mains supply, such as Eskom in South Africa, however unreliable this power source is. Using the mains supply, when available, either an external or internal battery charger will charge the bank of batteries, storing the necessary power required for those critical times when there is no mains supply, and you would normally be left in the dark. The stored power in the batteries is then readily available to be used by a suitably sized power inverter to provide you with 230VAC power supply, needed by all your critical office equipment.

The DC AC power inverter / battery charger combination can be used as an extended AC power supply system.

Combination power inverters have built in battery chargers and transfer switches, which makes them an affordable, hassle free solution for your “uninterrupted power requirements”, giving you almost seamless power supply, by switching over automatically to provide emergency back up during power failures or limited power availability.

The big benefit of these power inverter units over proper UPS systems is that you can size your own battery pack to it, thus providing you with as many hours of back up as you need.

They also have 3 times power overload surge ability which is absent from most online UPS systems.

The combination power inverter/charger units can be used in conjunction with very small and much more affordable UPS units, for the likes of computers, which require a very fast switch over function, in order not to lose any data.

The following DC AC power inverters can be used as UPS systems, and/or in conjunction with small UPS systems:

then please do not hesitate to contact us - we will be pleased to assist you

Load shedding

This has got to be the latest buzz word in SA at the moment.

Power solutions are offered in abundance, providing most of us with even more confusion than anything else.

Our advice is: Be informed. Make your decisions wisely, and think long and hard before taking out your hard-earned money and rushing out to the nearest discount store to buy a generator offered at bargain prices.

We offer sound advice by ensuring that we, as well as you yourself, understand your power requirements and help you look to the future, thus making wiser long term decisions.
Amongst the many back-up power solutions we have designed, one that is very popular with businesses is an inverter and charger combination unit with seamless automatic transfer from mains supply to battery. This system allows one to utilize a generator to substitute power from mains and will naturally form part of a solar power based system in the future.

The size and number of batteries in your system will dictate the total number of hours back up time you have available in event of a power failure.

You can start off small with a minimum amount of batteries and add to them as your budget allows, thereby adding additional hours of back up.

An inverter/charger system that will provide you with power for 4 x 12W lights, 1 x DESKTOP PC and a laptop for 3hrs will cost you around R 7300.00
To extend that time to 6hrs will cost you an extra R1360.00
Recovery time after a six hour power failure will be approximately 8hrs.

The full range of UPS type units we offer are:
