LUMINOUS ZELIO+ 1100/12V (E-comm) Pure Sine Wave Inverter

Please suggest, if we buy these inverters from online, only for wiring and setup purpose need to spent additional amount. 

Luminous is bad. I have similar Luminius invertor at home. I don't know if it is exact same model, but it looks same and same power rating. Its horrible. 

1. It has a fan that makes so much noise randomly. Like, even a ceiling fan cannot make that much noise in full speed. It comes on randomly for like 10 minutes even when it is cool climate and the inverter is not in use.

2. It makes 5 loud beep sound each time electricity goes off, and 1 beep when electricity comes on. It is so annoying to see it make so many beeps.

Luminous Zolt 1100 costed me ₹4400 on first day of Great India Festival.

And purchased Livgaurd 160A 66 months battery for ₹12600 from Flipkart and battery delivered within 24 hrs thru a local vendor.

Bought this model last year from flipkart for around 5500 . This is working good so far, did not observe loud beeps and fan noise.

Dont know about Luminous but wanted to share experience about Microtek. 

Bought Microtek (HB 1275) 2 years back. It was dead on arrival. Then the shop dealer said Goods once sold cant be replaced. He is very popular Inverter dealer in that area. So called Microtek, Service was decent. They asked if I bought from Microtek authorised dealer. I told him that the shop I bought from had "Authorised Dealer" certificate. Service guy said anyone can buy that certificate. Then I asked, if so then point to the Authorized dealers since their website had none. He didnt respond. 

Then his manager said if I need replacement I need to send it to Delhi, wait for many weeks and see if they accept defect.  For this I will have to carry it for 15 kms to my city Branch office and drop it there. They wont pick it up. 

If Head office in Delhi accepts (which he told was rare), they will replace. Else they will quietly replace the faulty component and send it as new. He said better to get it serviced in front of my eyes at home. 

So I said ok. Service guy came, the whole core component of Inverter was faulty. So he just unscrewed it and replace full set. And since then no issues in basic functioning. reasonably quiet but keeps charging for several hours if we lose electricity for 3-4 hours.

My neighbor has the basic popular White color 1100 series Pure sive wave inverter. he had 0 issues he said.

Also I learnt we had Neutral wiring issue in DB box, Inverter went crazy. It wont work if Neutral line is faulty.  

@Censuresh are you still seeing the small appliance pass discount?
