The Sunny Boy 700 is factory set for the highest input voltage. To be able to use it
for smaller PV systems, you need to make some minor modifications to the unit. Inside
the Sunny Boy 700 at the top right there are a number of terminal blocks. The top
double terminal is not relevant for adjusting the input voltage range. Below the
double terminal there is a single terminal. This terminal is used to adjust the input
voltage. Below this terminal there are two free slots. You can see the input voltage
ranges associated with the slots from the drawing below.
The slots for the jumpers are
mounted on the Sunny Boy 700's
controller board. When supplied
from the factory, no jumper is fitted.
A jumper only needs to be used if
you want to operate the Sunny Boy
700 with a lower input voltage, i.e.
at 96 ... 200 V DC or at
73 ... 150 V DC.
