Here in this post, we are going to show you the back panel pictures of various leading inverter models available in the market.
- Sukam shiny –Pure sinewave
- Microtek SEBz pure sine wave
- Exide Inverter – Pure sinwave
- Luminous – Pure sinewave
- Amaron – Pure sinewave inverter
Almost all leading inverter models have the same kind of features, but they differ in outlook.
Some companies give different name for the same function in the inverter to differentiate their product from the crowd.
So, don’t get confused, we will describe you about the sliding buttons and other functions you see in the back panel of the inverter. No worries!
Back panel of Sukam Shiny Inverter, a pure sine wave model from Su Kam.
In the above picture, there are two switches in between the power output socket and cooling fan.
W-UPS ——–UPS
LA ————-SMF/TUB
Let us explain the functions for the above two switches,
W-UPS means ‘wide UPS’ mode, which means the inverter operates in voltage range of 100 V to 300 Volt.
In this wide UPS mode, the switch over time is little longer compared to ‘UPS’ mode. So, if you use desktop PC connected with Inverter in W-UPS Mode, your PC would restart during power cuts.
It’s better to use UPS mode when connecting your desktop PC with your inverter for power backup. You won’t lose any unsaved data in your computer during power cut.
This UPS mode ——W UPS mode is just similar to voltage selection button in Microtek Inverters.
In simple words,
W UPS – 100 to 300 Volt
UPS – 180 to 260 Volt
There are some advantages and disadvantages in using ‘UPS’ mode.
If you use UPS mode in your inverter, during evening time when the overall power consumption rises, you might face some drop in voltage from grid. If your grid power voltage goes below 180 v , instantly your inverter switch back to battery mode and start using your battery power,
NO power cut required, just a low voltage will trigger your inverter to switch back to Battery mode. This is the big problem with UPS mode in any inverter. If ‘Low voltage’ occurs frequently, then you will end up in low backup or no power backup when the real power shedding happens L
Conclusion
If you plan to use Home UPS for your desktop computer, better you switch on UPS mode button, only when you use your desktop computer. Switch it back to W UPS mode, when you shut down your desktop PC.
W-UPS mode (wide ups mode) or wide voltage mode (100 to 300v) is always safe and gives better battery life. If you don’t use any desktop PC with your inverter, always keep your inverter in W-UPS mode (100to300V) to get better battery backup during power cuts.
Laptop users don’t need to use UPS mode, laptops have internal battery and they don’t reboot during power cutsJ
Battery selection Switch or Charge current selection switch
You will find another important switch in the back panel of Home Ups,
Battery selection switch, which is called as charge current selection switch.
—————————————————————
In Sukam shiny
This switch is labeled as LA ——SMF/TUB
LA – Normal charging mode (up to 10 amp)
SMF/TUB – High charge mode (up to 15 amp)
LA means Lead acid battery or Normal Inverter battery.
SMF means Sealed Maintenance free Battery
TUB means Tubular battery (both short and tall tubular)
————————————————————-
LA battery or Normal inverter battery – Most non-tubular inverter batteries comes under this category.
LA mode in Sukam shiny gives only normal and safe charging current (upto 10 amp) to connected battery. This is just a safety measure to ensure long battery life.
But during long and intermittent power shedding, we would recommend using the high charge mode (SMF/TUB) for Normal inverter batteries (non tubular). Slow or standard charging mode won’t quick charge your battery. It is safe to use batteries like ‘Exide inverter plus’ in high charge mode to handle and intermittent power shedding.
Caution: How ever we recommend High charge mode (SMF/TUB) for normal inverter batteries, we also recommend not to use high charge mode for batteries older than 3 years ( both LA and Tubular)
Batteries older than 3 years are not capable of accepting the high charge current (up to 15 amp), there is a risk of battery failure.
Play safe!
Replacing the FUSE in Home UPS / INVERTER
This is just a simple job to restore your inverter.
Fuse in the back panel of the inverter may blow at times of high voltage or any other voltage fluctuations in the grid.
NO need to call a technician to replace this fuse. Most inverters are provided with spare fuses. Check your inverter box for spare fuses. Some electricians will take the spare fuses provided with new inverters during installation and they don’t allow the consumer to replace it themselves.
It is a not that much complicated job, you can try it yourself.
Just open the fuse cap at the back panel of inverter (open it like opening a bottle cap), check whether the fuse is blown or intact.
If you find faulty or blown fuse, replace it with new fuse provided with your inverter.
Caution: Switch OFF the mains supply before working on your inverter. Replace the blown fuse with same amp rating, never try with lower or higher amp rating.

Amaron Inverter – Home UPS
————————————————————
Microtek SEBz Pure sinewave inverter
Most users complain about the reboot problem when using home UPS with desktop computers.
This is not a problem with inverter, you need to set the right mode in inverter before connecting desktop PC to your inverter.
We have already published a article about Microtek back panel switches configuration

Exide Inverter – Home UPS
Exide inverter has three modes for charge current selection.
To know more details on this
Read this post about Exide Inverter Charge selection Switch
———————————————————————————
Luminous Inveter Back Panel switches
Luminous Inverter backpanel is slightly different from others.
It has two Fuses
Charger fuse
Main Fuse
No confusion, luminous has provided two fuses to facilitate the maintenance process.
In Luminous, there is a cap on Charge current selection switch or battery selection switch. This is just a precaution to avoid making frequent changes in charge current selection. As we already said, using high charge current settings for old batteries is not recommended by most inverter manufacturers, so they put a cap on charge current selection switch.
Don’t worry, you can make changes by removing the cap, it’s always safe to use high charge current for new batteries.
UPS Mode – Normal Mode switch In Luminous
In Luminous inverter, you can find this UPS mode – Normal Mode switch with different label
Regulated UPS mode – UPS Mode – Narrow voltage mode – 180 to 260 V
UnRegulated UPS Mode – W UPS mode – Wide voltage mode – 100 to 300 V
Regulated UPS mode is best for using desktop computers with inverter. No reboot problem!
If you don’t use Desktop PC, then Use the default Unregulated UPS mode for better battery backup and performance.
Very good article. Keep Posting.
Thank you Sanjiv!
Nice article and very useful for the people who are new to the Inverter and guides to check the functions available in the inverters
Dear Admin,
I have Skam 850VA shiny coupled with new Luminous 150AH tubular battery. My queryies are as below –
1. Is it a better option to put the charging option to LA(normal 10Amp) only whether the battery is new and tubular, for increasing the battery life, given the powercuts are not that frequent and for only a few hours a day.
2. Does switching the charging mode a bit frequently(from High to low current) affects the battery life? I. e. When I don’t feel the need for fast charging I will keep the charging mode to normal, if some day power cuts are frequent for long duration I will flip the switch to fast charging mode.
Dear Amit,
Unless u experience long power cuts you don’t need to use
fast charing mode.
Using normal charging mode in inverter, helps prolong the battery life.
Frequently flipping the charge selection switch does not have big impact in battery life. It is smart decision to use fast charging mode, only when u need quick charge.
I am truly sick and tired of replacing fuses on the inverter back panel. All it takes is a bit of overload to blow the fuse. Sometimes those glass fuses completely disintegrate or melt inside the little fuse holder and then it becomes a nightmare to clean out bits and pieces stuck inside it.
The inverter also starts blaring a high pitched alarm as soon as the fuse blows that will drive anyone nuts. I am about to toss this piece of junk in the bin. Its high time manufacturers started using only MCBs for their inverters. We don’t live in the 19th century anymore for Pete’s sake.
I am using luminous inverter my charging light is blinking sir please tell me how to fix this problem . my all switch connected with inverter are not working i am in very big problem pls pls tell me
Hello,
There is a charging voltage selection switch in microtek sebz900va inverter. Do i need to keep charging voltage high if i want to charge with high current? I have a 220ah tubular battery. Please reply. Thanks.
Yes very Useful Information Thanks a Lot Dear Admin.
Dear Yousuf,
Thanks for your kind words.
FP mode is better 🙂
Hi,
I have Luminous Eco Volt 1050 with Exide TM500 15AH battery. It is just one month old and not giving back up more than 3 hours.
It is connected to two Desktop PC’s with 19″ LED monitors and two CFL (20Watts), and a Ceiling fan. It was only giving backup for 2 hours only.
When the power went off next time (inverter was showing battery was full charged), i switched OFF the CFL and Fan. used only two Desktop PC’s with 19″ LED monitors. But still it was only giving backup for 2 to 3 hours only.
Then i noticed that the battery selection switch was in the wrong position – in the Flat plate. I have changed that to Tubular. Back up is slightly increased to 3 hours.
All these time the battery charging current selection was in Medium as my battery is 150AH.
One of my friend is using Luminous 650VA inverter with 120AH Battery, and he is getting 6 to 7 hours backup. I wonder what went wrong with my Inverter.
1) wheather the wrong battery selection would have ruined my battery ?
2) Shall i set the battery charging current to High?
3) or shall i call my vendor / service person to solve the issue ?
4) Please, suggest how to improve my backup time.
Thanks in advance.
I am using Luminous Cruze UPS (3.5Kv). I have a real problem which is that the UPS will enter NL mode and switch off the load when there is less than 10% of load.. This is a massive problem since we rarely use more than 300 Watts and the machine will switch off twice daily..
IS there a way to either disable this mode OR reduce the Nl watts to MUCH less e.g. 10 watts..
Right now we can not really use this machine since it keeps cuttting power twice daily.
thanks
This is the big problem with ‘No load shutdown’ feature in big inverters.
You should book a complaint at luminous customer care.
Faulty chip is causing the problem here.

Dear Admin,
I am using Sukam Falcon sine wave 800 VA inverter. Previously i had used Exide Inverter plus IT500 150Ah battery which lasted 5years. I always used normal changing mode (LA). Now I replaced my battery and purchased Exide Inva plus IT500 150Ah battery fifteen days ago. I want to know that I should charge this battery with normal charging (LA) or high charging mode (Tub). In my area power cuts apx 5 -7 hours.
Hemant Sharma.
Dear Hemant,
Answer is simple
With normal mode , you get better battery life and normal backup
With high charging or Tubular battery mode, you get little shorter battery life and extended battery backup
Exide IT 500 is 100% compatible with all modes of charging

Is any problem to inverter, if frequently change UPS mode and ECO mode?????
Dear Admin,
I Have a 2KV Exide inverter which gives intermittent issues like once in 1 or 2 days it keeps switching between mains and ups numerous times, sometimes lasting upto a hour. Tube lights keep turning off and on at these times. My inverter is 4 months old. This issue i am facing is for last 15 days. And in the above period my PC has shutdown 5 or 6 times, only when there is this frequent switching. I did check the voltage with a . multimeter when there is this problem, the voltage seemed to be steady . Didn’t have any issue for last 3 months. Pls guide me.
