# I Own Microtek UPS SEBz (3 year old) – But not getting good backup – My new battery also requires water toppings frequently – Why?
You inverter is three year old. There might be some problem in the circuit board.
Microtek has upgraded all its components in the PCB of UPS SEBz model in recent years, the new PCB is now more advanced than before.
We strongly recommend to change the PCB in your inverter. (PCB means Printed circuit board)
It’s a simple process that needs hardly 20 mins to complete.
A new PCB-Printed circuit board (full set) for Microtek UPS SEBz 850 va would cost around Rs.1200 (including service charge),
All you need is to call your nearest microtek dealer, and ask him for PCB replacement.
Dealer might confuse you with different reasons for low back up, slow battery charging, overcharging and overload problem in your old inverter, just ignore it and ask him to send microtek service engineer to your home for PCB replacement.
# Is this applicable only for microtek Inverters or shall I try it with my old sukam inverter?
This is applicable for all branded inverters
Inverter should be at least 3 year old
If your inverter is few months old and not stable, you could try replacing PCB.
By replacing the PCB in your home ups, you could get the following benefits
1. Solution to low battery backup problem
2. Better charging current and quick recharge of battery during intermittent power shedding.
3. No frequent distilled waters toppings required for battery. Correct cutoff voltage for low and high battery charge status.
4. Better load bearing capacity in battery mode.
5. Better battery life assured.
Give it a try, just Rs.1200
That’s it!
Dear Admin,
This is a wonderful idea.
Many people earlier had purchased square wave inverter.
Wish there was option for consumers to upgrade to sine wave via kit from manufacturer at a cost.
just an idea for add on services for manufacturer.
Hello Admin,
I have problem in sukam shiny UPS, i.e battery charging cutoff is not happening (in trickle charging) and require frequent topup. So visited many shops but they have very little or zero knowledge about trickle charging and said purchase a new battery.
so I called sukam (pune) and asked then to diagnose problem, they said replace the card, it will solve the problem. I agreed and asked then problem should be resolved if new card will not work then will not pay anything.
service engineer came and checked voltage , trickle mode cutoff. So opened the inverter and replace a card and cheked. it din’t worked so he went to service station to get the another card, he opened pack found that PCB burnt. Again opened another new card, installed it, but it fan not working.
I was surprised that all card was recycled (repaired) and few card has solder with copper wire whose line (bus) was burnt on card.
So looking at this type of card, I asked him to install my original card because I will not pay for old repaired card.
This type of practice I have seen in past also and some reputed brand doing this like Kent, Zerob, Eureka and now this time SUKAM.
its is very difficult or impossible to get new part for branded product, atleast for above brand.
I would like to know from where I can get original (new) part for Inverter (Sukam).
Since, my inveter is three old so planing to scrap it instead or repairing.
One more thing, does battery reconditioning (with EPSOM salt) works? because no one at many battery shop know about reconditioning process or might be they don’t want to disclose it because they will force customer to buy new battery.
Sir, Please tell me that where can i get original part and does reconditioning (EPSOM / Castic soda) method works?
Thanks!!
Sadly, some service engineers are using reconditioned PCB’s.
Before installing, we should make sure that it is new and original.
You better scrap your old inverter and buy new one. You could exchange it .
We do not recommend battery reconditioning.
Better you try bench charging at any battery service center.
My Microtech inverter 750VA got burnt – I heard a loud noise and smoke emanating. I called Microtech service 01142733377. The engineer came on the following day. He informed me that PCB had burnt. I saw a small part of it indeed burnt. He informed me the replacement would cost Rs. 1250. So I asked him to change the PCB. He said he put a new 950 VA PCB. Next he told me the connectors were also burnt. I asked him to replace the connectors too. I thought he would charge me 1500+ ( cost of PCB+service charge 250=cost of connectors. Fortunately I read this blog in the meanwhile and learnt the PCB replacement (with service charge) was about Rs1200. I told him to charge less considering my old age with no income. He issued receipt for Rs 1200 and I paid the amount. Thanks for the blog for it save me from paying more.
Happy to hear this kind of positive review for our blog ☺
Thank you so much for sharing your experience.
Hello ,
Very nice and informative blog posts , i am really really hoping you would reply
i have a 6 years old microtek Sebz 1500 va inverter..
even when it was 1 year old i had tried to put it on “ups mode” 180v mode and used it to try to run my pc but it would restart during powercuts or fluctuations when it would switch to battery mode.. pc works fine with back ups.. generic non gaming pc
my room is around 18-20 meters away `from inverter location.. and i don’t have load more than 3 tube lights and 3 fans at a given point of time.. 2 common standard Ah size batteries
the small cfl located near to inverter shows a “1 very quick flicker” when i switch off power even on ups mode.. the inverter is otherwise ok..
1) will changing pcb really help in my case ? or are there any other parts also responsible for switch over time delay like transformers , capacitors etc that would require repalcement ?
2) is distance going to make a difference ? or does pc has to be near inverter for it to not restart ?
Thank you very very much for reading and i hope you would reply 🙂
Dear reader,
Replacing PCB will solve your problem
Distance is not a problem, in UPS mode your pc should not reboot during power cuts.
Thank you sir ,
Please answer following questions
1) Can we use SEBz 1600VA PCb for Sebz 1500Va model ? will it be compatible ?
2) What should be the cost for that Sebz 1600va PCB ?
Thanks , please reply
Dear Nick,
You can use the PCB of Microtek SEBz 1600VA for SEBz 1500 VA model. It is compatible. No issues.
Cost should be around Rs.1800
My Microtek inverter PCB got burnt due to lightening , I want to change PCB, Microtek is charging Rs2050, i feel it is expensive, so decided to buy new inverter.
HI AM using Microtek UPS SEBz 900 VA,(UPS SEBz GOLD, SINEWAVE 905G).
i have experienced very worst service from the authorized service team..
My ups gone bad within the warranty period, The PCB got bunt out.
With the authorized service person we got replaced the PCB with lots of /lots of efforts. (with the help of local dealer).
After replacement noticed
– heavy noise,
– for charging taking huge time , almost 3-4 time than the previous (original) PCB.
– Automatic changeover fault. After some days stopped automatic change over.
– Repeatedly fuse blowing .( No change in load )
After two months again the PCB failed .
In the beginning he use to say that we replaced the new PCB. When we checked personally the PCB looks like repaired one.
again when we enquired with the service person, he said we replaced with the repaired PCB not a new one. He said this is the practice they follow. this is the instruction they follow.
Now when we asked him to replace the new one, again he is saying the same thing that he can replace the repaired PCB only, not a new one. this is the instruction from company. After replacement the faulty PCB they keep it with them only. And he is charging 1500/- for the same. And they wanted to keep faulty PCB with them. i don’t understand when we re paying for the new PCB , why should we give the our old PCB.
As per him to replace the PCB, the charges will be 1500/- and he want to keep the faulty PCB. If we don’t want to give the faulty PCB the charges will be 4000/-
have below queries
1. If Within the warranty period if board fails ( consider service person cannot repair at site) , in that case do you replace with new board OR do you fix any used / repaired board ?
2. What will be the charges for the new board for UPS SEBz GOLD, SINEWAVE 905G (part no.:17BG3SCAF019453)
The location pin code is 591316.
3. After the warranty period , if board fails , does your service person replace with new board OR any used / repaired board.
4. When we are paying for the new board, why the service person collect the faulty board.
5. Will we never get the new / original board from company ?
Hi, I am having 7.5 KVA Cruze Sinewave UPS with Sr. No. 23G943C1001135. A Month back the same was down, there was no output. Got diagnosed by the dealer. After inspection found PCB was faulty. I wanted a refurbished or new PCB for the same. We also need to fit the same on the ups. Kindly send us the quote for the same. You can call / Whatsapp us on 9130074667
