The Sunny Boy has two input areas, "A" and "B", each with their own MPP tracker. Up to two strings
can be attached to each of the two input areas. They must fulfill the following requirements:
• Per input area (A or B) the following requirements of the connected modules apply:
- Same type
- Same number
- Identical alignment
- Identical tilt
• When connecting only two identical strings, it is more efficient to connect them to just one input
area.
Exception: Shadowed strings or if the total input current is greater than 15 A.
