WIRING THE PCB-120 SERIES CONTROLLER
The PCB-120 Series controllers are limited to a maximum of eight 17 volt panels
connected in series for the 120 volt systems. However, more panels may be
connected in parallel.
This controller has a 4 position preset input voltage selector switch designed
for various solar module arrangements. Please refer to the selection chart for
the switch position for your system.
CAUTION: Only one of the 4 preset switches should in the on position at one
time. These preset voltage settings will work with the majority of the standard
solar modules on the market. If you need to change the voltage set point, the
"panel voltage adjusting pot" will allow you to do so. (Refer to the controller
adjusting procedures. CAUTION: If you change the voltage setting using the
adjusting pot, it will change the set points on all 4-selector switches. It is
highly recommended you do not adjust this pot.
