Power backup kit (3000W / 48V / 30A charger) with four batteries
The products shown here are particularly well suited for homes, townhouse developments, farms and guesthouses. These systems should also be considered for small businesses such as restaurants, shops, medical practices, pharmacies, workshops, etc. where data capture/transfer is not necessarily critical. (For critical backup such as for servers and important computers, you should consider a UPS system.)
Individual shops in shopping centres would find these systems ideal as they can basically be installed anywhere unlike generators. We offers cost-effective, reliable and carefree back-up systems.
On average these systems need about one sq. meter of space only.
The advantage of these products is that you don't have to install a noisy generator. Generators need constant refilling and maintenance and are not ideal for residential areas or for small businesses where noise and pollution from the exhaust are a problem.
The systems offered here consist of a pure sinewave inverter, with a built-in battery charger, automatic changeover switch and a large battery bank
Excludes remote control, DB (In picture), Electrical and DC commissioning
How do these systems work?
The unit is permanently connected to utility power so that while mains is present the extra large built-in battery charger recharges the batteries and keeps the batteries fully charged until a power failure occurs. The equipment you want to back up is also permanently connected via the system. In case of a power failure the backup system automatically switches over, via an extra fast transfer switch to the inverter, which will continue to provide power to the equipment within 15 msec. This is extremely fast and standard equipment like TVs, DSTV decoders, microwaves, fans, etc. are unaffected. The sinewave systems can also backup computers but it is possible that a very small percentage of computers could reset during the switchover time.
When utility power returns, the whole procedure is reversed and the unit will switch back to utility power and will automatically start re-charging the batteries. Your equipment remains connected to the system even when power is restored. The whole process is fully automatic.
You can connect the following appliances to the inverter systems as long as the total power consumption does not exceed the maximum VA rating of the unit:
- Small to large Plasma or LCD TV
- DSTV and MNet decoders
- Surround sound systems
- 5 to 10 energy saver lights
- a Fan
- Fridge and deep freezer
- Home alarm system
- Automatic garage door motor
- Electric fence
- Microwave oven
- Small kettle
- Fax machine
- some standard home Power tools
Avoid connecting the following items which have high inrush currents or use a lot of power:
- Underfloor heating
- Air conditioners
- Washing machines
- Tumble driers
- Pool motors
The larger inverter systems (5kW, 6kW, 8kW and 10kW systems) are able to run most of the more 'power hungry' items. Some of the more sophisticated systems are also available in three phase up to 72kVA
