I have this inverter where in i have 2 strings each facing east and the other is west,

the problems I see as of now is that the inverter will get both AMPeres and balance everything out, this makes the output smaller than expected, as I check the manual of the said inverter, it has a 2 mppt, based on the SOLAX website "| http://www.solaxpower.com/en/x1-boost-3/   "

eg, 1 string will have 2.5kw while the 1 string has a 1.5kw, this will bring down the amp of the said inverter down...

Is this normal for all inverter to balance the ?

    It will be lower, but over a greater time span. For a grid tied system, East and west facing arrays have no advantage that I can see. 

    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Magnum MS4024, Prosine 1800(now backup) and Exeltech 1100(former backup...lol), 660 ah 24v Forklift battery(now 10 years old). Off grid for 20 years (if I include 8 months on a bicycle).
    - Assorted other systems, pieces and to many panels in the closet to not do more projects.

    the problem im seeing right now is that the inverter is trying to balance amp and the spec is that its a dual mppt... probably some setting is needed....

    There is a string sizing tool on the website, See if your configuration is valid. You need to make an account and login.

    Probably a good move. I am not familiar with it, and have only heard of one other in Australia.
