7.2 System Wiring for 24 V Battery Installation
“Series” Wiring
is shown, for
nominal
24 V system: Voltage from
panels will read 45 V when discon-
nected (open circuit).
Installing a Solar Tracker?
Use
stranded wire for flexibility. Secure
the wires to tracker with plenty of
tape. Leave a good slack loop to
allow free motion of tracker.
Remote Tank Float Switch
: Con-
nect float switch to terminals 4-5 of
the pump controller when it breaks
contact on rise, to turn the pump
OFF.
Otherwise use terminals 3-4 for
opposite function.
Grounding:
Connect
either battery minus or
solar minus to ground,
never connect both to
ground!
7.1 System Wiring for 12 V Battery Installation
12 V
system
: Voltage from panels
will read 22-25 V when discon-
nected (open circuit).
Connect the pump controller directly
to battery bank.
Remote Tank Float Switch
: Con-
nect float switch to terminals 4-5 of
the pump controller when it breaks
contact on rise, to turn the pump
OFF.
Otherwise use terminals 3-4 for
opposite function.
Grounding:
