Solar inverter need help with EAST / WEST facing string on a single inverter...

ChanChan Registered Users Posts: 45 ✭✭
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, Prosine 1800 and Exeltech 1100, ForkLift battery. Off grid for @13 of last 14 years. 1000 watts being added to current CC, @2700 watts to be added with an additional CC.

    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.
