![]() (i) Loading Inverter above the rated capacity (vii) Loose battery terminal (3) Inverter over load Also, while Inverters can backup for hours or days, UPS may only last for minutes or few hours, their major design is to retain power temporarily and prevent interruption only until the main power source is restored.īasically, all the major problems common with all Inverters and/or common error displays will fall under one or more of the headings listed below.ĬONTENTS OF THIS ARTICLE (1) Inverter Not Charging In summary, all UPS contain inverter circuit within them, but not all Inverters perform voltage regulation that ensures regulated power during interruption, as UPS would do. The size of charger in Inverter enables them to charge larger size and number of external batter(ies) than the UPS would do hence, Inverters are further distinguished by the size and number of batteries they can be operated with, which also determines the runtime during power interruption. ![]() Secondly, Inverter operates with external batteries because of their size in contrast to UPS. Since there is no real switching taking place in an online UPS, it is recommended to connect very sensitive equipment, like servers, switches, computers and other communication equipment to UPS/online Inverter. If the input voltage is poor, the output voltage will also be poor. It is simply garbage-in-garbage out meaning, whatever voltage comes in is what it gives out at the output. Such Inverters cannot guarantee data protection especially during power fluctuation or when power is out of range. they use some system of relay for switching. In other words, they are not equipped with interruption-free circuits. While UPS is built primarily for short time data protection when there is power interruption, because it can perform voltage regulation at the output, some low grade offline Inverters on the other hand are intended primarily for backup only, but not equipped for smooth transition between power interruptins. This wide time lag may be noticed as power interruption by sensitive equipment. Switching time for UPS is in the range of 0.5mS to 5mS, while for Inverter, it may range from 20mS to 500mS. The AC supply is converted to direct current (DC) by means of a rectifier on the Inverter circuit to charge the battery, which is DC. The charged DC battery is then inverted back to AC (Alternating voltage) via a step up transformer, which is what supports the load (equipment) during power outage, hence the name "INVERTER". Ther are other Inverters too that do not incorporate the use of isolation transformer, they are called Transformerless Inverters.Īpart from the runtime, there are other features that distinguishes an Inverter from a UPS.įirst, the switching time between the UPS and some Inverters differs. It has an input source connected to mains from public utility source, or a Generator. Introductionīasically, Inverter is just a form of UPS but with longer backup time. ![]() This introduction may be part of the solution though.
