micro inverters help with shading issues, but I'd rather see some form of DC balancing handle that before sending to a centralized inverter which can be more efficient, and not cause any problems for off-grid and battery backup situations.
'AC coupled' off-grid inverters can work with 'grid-tie' micro inverters to provide back-up power... http://magnumenergy.com/wp-content/u...g-Rev-5-10.pdf
