Typical wiring for PV
array-direct system
(no battery)
Example: 36V
For a 24V system, modules are
wired in groups of 2 instead of 3.
For a 48V system, modules are
wired in groups of 4 instead of 3.
Explanation
3 modules in series increases
volts to 36.
2 or more sets in parallel increases
the amps & watts.
A controller (current booster) is NOT
required with SunCentric™ pumps.

Ground the array framework to
earth for lightning protection.
Do NOT ground the power negative.
