The difference between an inverter and an UPS is in the amount of time the device takes to restore power supply in case of power failure. A good UPS can switch over to battery power in under 10 milliseconds. Since in the PC, any delay above a few milliseconds (10, I think) leads to a restart or shutdown, the UPS is ideal. An inverter is just like a UPS but it a bit slower in switching over to battery supply, and so is not suitable for use with the PC, since there will be a restart/shutdown everytime the mains go off. But in devices where this aspect is not critical, the invertor is enough. The amount of backup you will get is a function of the battery capacity of the UPS. The greater the AH rating of the battery the greater the backup time. The VA rating on the other hand is an idicator of the load the UPS can support. If you need longer backups you need bigger batteries (with higher AH rating), not a bigger UPS (with higher VA rating).

An inverter typically converts power, say 12v DC, into standard household power, 110v AC.
The UPS (Uninteruptable Power Supply) uses batteries or a generator and a power inverter to supply AC power to devices when a power failure occurs in order to keep the devices running.

Frequently Asked Questions for UPS & INVERTER
UPS
1. Why do I need a UPS (uninterruptible power supply)?
If you need optimum performance and longevity from your electronic equipment
and if you need a reliable short-term backup power source in the event of a
blackout, then you need a UPS to protect your equipment.
2. What is a "Smart" UPS?
The real meaning of “smart” UPS is one, which has a built-in microprocessor and
an RS-232 interface port. In addition to automatic shutdown capability, a "Smart"
UPS is able to monitor more operating parameters, such as: Input & Output
Voltage and frequency, Load Level, Battery level, and more.
3. How do I determine what size UPS to get?
UPSes are sized by their volt-amp (VA) load. To calculate the VA load of your
system check the UL label for the operating voltage and amperage drawn. Add
the amperages of each component to be powered by the UPS and multiply the
number by the voltage (120V for US applications). This number is your VA load
and the minimum size required. It is good idea to size your UPS at least 30%
larger than the minimum VA load to leave room for future needs.
4. Should I put a UPS at each workstation?
Yes, it is a good idea because this is where the most recent work is being done,
and this data is most vulnerable to loss or corruption in the event of power
outage.
5. Is there any equipment I should not connect to my UPS?
In general, you shouldn't connect a laser printer to your UPS because a laser
printer draws a tremendous amount of power and will likely overload your UPS
and cause the UPS fuse to blow. Most of the office equipment, such as
computers, monitors, fax machines, and networking equipment, should work fine
with most UPSes. Do bear in mind that larger size monitors consume much more
power than smaller monitors and will likely reduce battery runtime significantly.
Also you should not connect a surge suppressor at the output of UPS, in case
the surge suppressor creates a short circuit and damages your UPS.
6. Why do I need Power Saving or Power Saving Plus (the power
monitoring and automatic shutdown software)?
During a power interruption, a decision must be made when and if to gracefully
shutdown the computer system. On a computer system that always has
someone within earshot and eyeshot, this is usually done manually – when the
UPS kicks on during a power failure, the administrator decides whether to ride it
out on battery power or to save files and close programs. However, on an
unattended computer system, nobody is around to make that decision. In that
case, during a power failure, the UPS will kick on and run the computer system,
but only until its battery is depleted. Therefore, it is important to have automatic
shutdown software that will safely shut down the computer system after a preconfigured
time period of when the computer receives a low battery signal from
the UPS. UPS monitoring and automatic shutdown software also can broadcast
power fail messages to network workstations, keep an historical log of abnormal
power conditions, and alert the system to page the administrator.
7. How do my UPS conflict with other devices?
If your mouse uses COM1 and your UPS uses COM2, the default hardware
interrupt (IRQ) settings for COM1 and COM2 are IRQ4 and IRQ3 respectively. If
your modem on COM3 is also using IRQ3 there will be a conflict with the UPS on
COM2. Since serial devices cannot share a communication port or its hardware
interrupts, the interrupt for the modem must be altered. Check with the modem
manual to find out how to change the IRQ setting. Suggested IRQ includes 5 and
10. If these two IRQs are not free in your system, you can use IRQ7 since LPT1
is capable of sharing it.
8. I plugged the UPS into wall outlet, but there is no power from the
UPS. Why?
You have not turned your UPS on. The power switch on Power Office Series
UPS have button switch located on the top of the unit and labeled "on/test". To
turn the UPS on, depress the button and hold it down until the green LED light
“Line OK" turns on and stay on. When the unit is activated, it performs a self-test
for short period of time. During this process, the Line OK light will turn off
momentarily and the Backup LED will turn on. After approximately 2 seconds, the
Backup LED turns off and the LINE OK LED will turn on and remain steady on.
9. What should I do with my non-working UPS? The company I bought
the unit from is closed?
You can call the RMA Department at Maruson at (714) 630-0228 to obtain an RMA
number. You need to provide the technician information regarding your device and a
copy of the invoice.
INVERTER
1. What is the difference between a Maruson Inverter and a typical
UPS?
The Maruson Inverter contains a separate battery bank as opposed to the typical
UPS. While it can be a superior charger, its charging current can go up to 70 to
120 A. Furthermore, the Inverter’s separate battery bank allows for a longer
discharging time from the larger current flow during the charging process. A 3-ton
air conditioner could operate from four to eight hours long using only one TriPro
Power Inverter.
The TriPro Power Inverter works for nearly all kinds of load.
2. Why does our product not called UPS but Inverter?
Power back-up’s basically break down to two types: Floating and Cyclic. As a
“floating” back-up, the batteries are recharged immediately after they have been
discharged every time. UPS belongs to the floating type; it is designed for short
period of power shortage. On the other hand, the “cyclic” back-up is designed to
provide power for long period of shortage. In most cases the batteries will only be
recharged after they become emptied. The Inverter, as it is called, does not have
to be recharged constantly. The inverter differs from UPS in its specially-tailored
design to provide back-up power for a long period of time.
3. What can the Maruson Inverter work with?
Maruson’s Inverter works with all kinds of 3C (communications, computers, and
consumer electronics). It is especially designed to work with consumer
electronics while the typical online UPS is only compatible with PC’s.
The load can be a vacuum cleaner, refrigerator, air conditioner, motor, or T.V.,
etc.
4. What are advantages of using an Inverter?
Combining all the advantages of having a separate battery bank and the
simulated sine wave technology, Maruson’s Inverter allows for a longer
discharging time that is indispensable to areas often experiencing energy
shortages. 90% of the companies in the Dominic Republic, for example, own one
or more UPS(’) and/or inverter(s).
5. Why chooses the Maruson Inverter instead of other online
UPS?
All the Maruson Inverter has a battery bank in which you can connect as many
batteries as you want. While it is compatible with all the computer and
communications appliances, the Inverter is also cleverly designed to work with
any consumer appliances. Most UPS’ on the market break down easily but both
the longevity and the quality of the TriPro Power Inverter are guaranteed.
6. How long will the Inverter work for?
How long the Inverter works for depends on how many batteries you have. The
TriPro Power Inverter allows for an unlimited number of batteries to work so that
whatever appliances connected could run as long as desired. However, typical
UPS’ found in the market do limit the number of batteries you can connect to.
7. Is there any functional difference between the “sine wave” and
the “simulated sine wave”?
Generally speaking, the structure of the simulated sine wave is simpler than that
of the sine wave. Products using the simulated sine wave technology often score
quite high in both capability and reliability. However, there are no big differences
between the two in terms of their functional abilities.
8. Why is there a common conception that the sine wave is
“better” than the simulated sine wave?
This common misconception comes from the fact that most power-generating
factories still operate with the sine wave technology. Most people are wrongly
educated in thus way that the sine wave technology is naturally better.
9. What is a green power generator?
The Maruson Inverter is a kind of green power back-up (or so-called generator):
It produces no noises, no smoke, nor any other pollution.
10. Why does the Maruson Inverter go through a Three-Step
recharging process?
The three-step recharging process is a new technology that allows the
recharging cycle to proceed faster. In areas where power shortages often come
unwarned, it is the best to keep the battery banks recharged at all times.
11. Where is the Maruson Inverter needed?
The Maruson Inverter is especially needed in areas that often experience long
periods of power shortage. Homes or farms in remote areas would find the
Inverter particularly useful because of its sustainability. Large retail stores or
supermarkets will also find the Inverter indispensable. For example, in case of a
power shortage in a retail store located in a metropolitan area, without noise and
pollution to the neighborhoods, the Inverter will supply the sufficient and
necessary power from emergency exits to refrigerators and video-recording
cameras. Here the Inverter could keep the food refrigerated and even prevent
possible robberies. Imagine how wonderful it would be and how many lives would
be saved when there is a fire in the movie theater and there is an inverter to keep
the fire exits operating.
