want to buy inverter. Need HELP!!
I currently have 1500 WATT 12V Luminous inverter. Brought it 2years ago. Its still running but have few issues. like the power button on inverter is no longer working(can be manageable). the real thing is i have attached two 150AH batteries to it. I’m worried as it is not 24V. will it effect my batteries life? also whenever the goes off and inverter runs then there is a huge buzzing noise from my fan and pc
after googling i found that if my inverter is not sine wave then this happens. Also i work as a freelancer and have beast like PC which consumes a lot of power under heavy load.
I dont have money to waste on inverters every 2yrs. after researching a lot the below are the choices left
https://www.luminouseshop.com/collections/inver...
the lowest price is 8500/- snapdeal
https://www.luminouseshop.com/collections/inver...
6000/- snapdeal
after upgrading the inverter my load will be 1500WATT – 1pc, 2fans, 3 lights sometimes mixy 
what should i do. should i upgrade or not or do you have any other brands in mind?? please suggest me before snapdeal removes the SBI CC offer. THANKS FOR READING AND TAKING TIME to ANSWER GUYS

Don’t use more than 1 batteries. parallel or in series definitely avoid. use good brand battery
between in which area you live? still power cut… 
If you are sure about that you ’re using square wave now, you should upgrade to sine wave since square wave is not suitable for electronic equipments (PC, TV, Mobile etc)
Go for the brand of you choice or based on the reviews, Brand name has nothing to do with the quality, all the brands are importing parts from oem (mostly from china) assemble it here and slap their logo and sell it like the made it from scratch
thanks for the replies guys
finally got this one https://links.desidime.com/?ref=forums&url=http...
for 8500/- on snapdeal as there is a service center near my location

I feel APC is better over luminous (though luminous provides all flash features). With 15-18% coupons you can find good apc inverters on ebay. Have purchased from the below seller few months back and seems to be good.
