HI
Can i have two arrays one facing east the other facing west on one inverter, will i lose power to the array that is not in the sun.
whaty is the best way to fix this without getting another inverter

How many charge controllers?

Even if you only had one MPPT charge controller you will still get something from the array that is not in the sun. The controller will try to find a compromise between the arrays.

This is for a grid-tie the inverter already has the mppt built in

Are these two arrays in series? (I really hope not)

What inverter do you have?

I hope your inverter is of the type similar tothe Sharp 3500 model :

If so, you are in luck, since it supports up to three differently oriented arrays.

If not, you're out of luck.

I have an advanced energy mm5000 watt it also has 3 brakers for 3 array inputs it is the same inverter as the m5 beaconpower

Not a great situation but much better than if both arrays were in series.

As long as each panel in each 48V string is in the same plane, the MPPT will come up with a compromise operating voltage.
