The amount of backup time is determined by the size of the connected battery bank and the load drawn from the system. The backup time is directly in proportion to the load drawn. The backup time is normally calculated at full load (i.e. if the system is a 2200VA system, full load is 2200VA). If you remove some of the connected load, then the backup time will be extended accordingly.
Solar Power Solutions 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.
No more Load-Shedding Blues, from as little as R22 000
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. Sinetech 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.
How long will the inverter system run when there is a power failure?
How long does it take to charge the batteries when utility power returns?

If there is a planned power outage, can the system last for the full power outage time?

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. Sinetech 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 or fully sealed Gel 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. Sinetech does supply complete systems with batteries and battery cabinets if required.
