You are correct on the info< your load is 5 kva if you want to run an ac (split 1.5 tons) a fridge, tv and few lights and fans.
What you dont know is that there are a lot of generators available in the marker for 5 kva. They have a lot of quailties and specifications that differ from one another.
A 5 kva chinese genset are available starting from 37000 ( no warrantiy) different names it really makes no differrence coz people just stick on various stickers on them , so brand is of no value.
Then there is one 5 kva (china) for 45000, its brand is Loncin or Kipor which are of ok quality with shop warranty i.e they rectify the problem if any accurs at thier shop.
The best quality that can come out of china is FIRMAN generator, 5 kva costs around 60 k(negotiable), comes with a 1 years warranty which is the maximum on generators and its company backed. This set has japanese parts in it and even if you google it, you can c that its distributed all over the world, namely U.S, S.A and australia majorly.
China has a lot of qualities and its self evident if you c this generator.
You can check it out : www.oanda.com.pk/products
look under gasoline generators.
I would not recommend you to take shershah into perspective coz there is no guarantee of sets and they have a name in decieveing customers since ages( they say something , give something else), you may find something good there too but its like finding a needle in a hay stack.
The used honda generator which is being assembled in pakistan by atlas motors will cost you around 90k min, current market price is of 115k. They are assembled in pakistan but with japanese parts. (same as firman)
As far as the firman experience is concerned : they are undoubtedly the best in the market , right up there with honda, infact for the price i would say they are better than honda as i have seen its performance and quality. They can also be seen at makro stores.
The people selling firman confirm they have sold more than 1000 sets in one year and so far there has been no probs.
