Note: The Sunny Boy has provisions for either one or two
PV strings. The positive and negative terminal blocks
each have two positions, so two pairs of DC-input wires
can be connected in parallel.
CAUTION: Avoid using wire nuts to join any wires togeth-
er or to make any connections anywhere in the PV system.
Wire nuts are a frequent cause of unreliable connections,
resistive connections, and ground faults.
8. Connect the positive and negative DC wires to the appropriate terminals in the
DC disconnect enclosure.
9. Fasten the wires while applying a torque of 15 in-lbs.
10. Verify that all connections are correctly wired and properly torqued.
