BUILT IN BATTERY BACKUP
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 ESKOM 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.
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.
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 Sinetech 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
