GSLC175-120/240
and
GSLC175-230
are the “inverter only” versions for Radian models
GS8048, GS8048A, and GS7048E. They have hardware for Radian inverter AC and DC
connections. Battery monitoring or PV capability must be installed as needed. Installation for these
items begins with the DC shunts on page 26.
o
