    Battery Backup Systems for Long Power Failures

    LOAD SHEDDING KITS

    With a great range of Load Shedding kits available at Toptronic Energy, you can keep the lights on during blackouts. Even when unexpected load shedding strikes, you do not have to compromise your lifestyle anymore.

    Toptronic’s products will help you to provide power through those difficult load shedding hours and other unplanned power failures. No noise, no petrol/diesel, no fumes. Seamless, instant, 100% automatic backup power.

    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. Toptronic 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 either a modified sinewave or a sinewave inverter; with a built-in battery charger, automatic changeover switch and a large battery bank. Frequently asked questions are answered on this page.

    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.

    Installation

    The smaller systems can be used as stand-alone systems or can be wired into your DB board. The larger systems can also be used as stand-alone systems but it is by far more convenient if they are hard-wired into your DB board. Toptronic will provide support, such as block diagrams, for the electrical installation.

    Maintenance

    These systems require minimum maintenance. Depending on the system chosen, the batteries are either semi sealed lead calcium batteries,fully sealed Gel batteries, Lithium Ion Batteries. Batteries are maintenance free and do not have to be filled. It is recommended that battery sets are installed in a battery cabinet and are locked in a room with ventilation, where small children do not have access. As with all batteries, these batteries can be dangerous if tampered with. Toptronic does supply complete systems with batteries and battery cabinets if required.

    What is the difference between a home long backup system and a UPS system?

    A UPS system is designed to backup sensitive equipment like servers, computers, medical equipment, telecommunications equipment, etc. Standard UPS systems have small internal battery sets and can only provide short backup times of approximately 5 – 10 minutes which cannot be extended as the internal battery chargers are small and can only cater for the internal battery sets they were designed for. Additional or external batteries cannot be connected to these UPS systems.

    There are also long backup UPS systems available which can be supplied with external battery sets to provide backup for, usually not more than 2 hours. If the user requires longer backup than 2 hours, the system would then have to be intentionally oversized to cater for the longer backup time, which can then be extended to 4 – 6 hours. For longer backup times, UPS systems should be installed in conjunction with a generator.

    The double conversion online UPS systems have no break whatsoever and the sensitive equipment will always run on electronically produced power and is not directly connected to the mains power.

    In contrast, inverter based long backup systems do have a small break when they switch over to backup power (irrespective of the inverter system brand or model). The higher quality systems, which Toptronic supplies, switch over in a very short time and it is hardly noticeable. Inverter backup systems incorporate larger battery chargers which allows larger battery sets to be installed which results in much longer backup times than UPS systems.

    In contrast, home long backup systems, which do have a small break when they switch over to backup power (irrespective if the inverter system, but the good quality systems have a power break during switchover which is hardly noticeable), incorporate large battery chargers which enables extra large battery sets to be installed, which results in extra long back-up times.This is not possible with UPS systems.

    What you need to do:

    Firstly we recommend you read the explanation. Then make a list of exactly what appliances you want to provide backup power for. You need the appliance ratings in Watts, Amps or VA (this is usually stated on the back of the appliance on a label or in the manual). When you have this power rating, add them all together to come to a total power rating. This can be done with the help of an electrician or someone who understands these calculations.

    You can then look at the different backup times provided by a particular unit. Please contact us for pricing and availability. We can arrange a trained electrician for installations in the greater Cape Town, Johannesburg and Durban areas.
