Note: UPS are temporary "switch-over" solutions that provide power for 5 to 15 minutes (100% load). UPS beep during a power failure.
An inverter is required to power devices for an extended period of time. Note that continuous power cuts will shorten battery life. The warranty covers charge cycles, not a period of time. Stage 4 load-shedding may shorten battery life to 6 months or less if batteries discharge below recommended charge levels (Lead Acid 50% DOD, LiFePO4 80% DOD).

An uninterruptible power supply, also uninterruptible power source, UPS or battery/flywheel backup, is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. *Note: A UPS will beep continuously when power is off. This is normal. Offline UPS Offline UPS connects the computer to the ESKOM's power grid (or to a generator) until the voltage falls below a certain level, in which case, the UPS switches over to battery backup. The switch-over time can be as long as 25 milliseconds depending on the amount of time it takes the standby UPS to detect the lost utility voltage. The UPS will be designed to power certain equipment, such as a personal computer, without any objectionable dip or brownout to that device. Online UPS Online UPS connects the computer directly to the battery backup at all times. This type of UPS is able to tolerate continuous under-voltage brownouts and over-voltage surges without consuming the limited reserve battery power. It instead compensates by automatically selecting different power taps on the auto-transformer. Double conversion UPS The primary power path is the inverter / battery and it is not the AC mains. This means that the output power is supplied by the battery all the time and no switch-over happens if power fails (0ms switch over) Other UPS features may include:
What is the difference between VA and WattsUPS are rated in VA (Volt-Amps). This is a basic rating for UPS and is the Voltage multiplied by the Amperage the UPS handles. At 220Volts, a UPS that can supply 1Amp would be rated 220VA. This however is not the real power for AC devices because AC power rating requires the power factor to be taken into account. A 1000VA UPS would therefore have an AC power rating of approximately 600Watts. What is power factor? In AC circuits, the power factor is the ratio of the real power that is used to do work and the apparent power that is supplied to the circuit. Typical power factors
UPS
are sensitive to the voltage and frequency on its input - this is the
way it detects whether it should switch to battery backup mode or not.
This is normal operation for a UPS. Some generators, especially the cheaper "home use" generators, are not always calibrated accurately when it comes to frequency (50Hz in South Africa), while the voltage seems to be in range. If the frequency is border-line, the UPS tends to switch over to battery mode whenever it falls out of range, and then switches off when it is in range again. The best way to correct this on/off behaviour is to set the throttle on the generator to a point where the UPS becomes stable. Note: A Voltage regulator / AVR will not correct the frequency and will do little to fix this behaviour. An AVR is all about Voltage, and the AVR will fix voltage fluctuations from a generator, protecting sensitive equipment from Voltage dips and spikes. | |||||
