TABLE 2
SELECTING PV MODULES
The 3000i is designed to operate conventional 12V 36 cell PV modules or higher voltage 60 cell modules. It is not intended for use with 72 cell
modules. If multiple PV modules are used best MPPT current boost performance will be obtained if all PV modules are identical. Dissimilar modules
should have V
MP
values within
0.5V or better and be of the same basic cell technology so their V
MP
will tend to track as operating conditions
change. If module types are very different consider using a separate charge controller for each module type to obtain the best MPPT current boost
performance. When multiple controllers are used on the IPN Network each controller independently MPPT’s their modules to thei
r best. Do not mix
36 cell and 60 cell modules on the same controller. Select PV modules that do not exceed the maximum ratings shown below, and preferably
produce I
MP
of at least 3.5 amps (2 amps with 60 cell modules) per 100 amp-hours of battery capacity.
Voltage, current and power produced by PV modules fluctuate widely with operating conditions. As a result a set of test conditions referred to as
Standard Test Conditions
(
STC
)
are used to rate modules in a meaningful manner and accurately predict real world performance. STC ratings are
not maximum or optimal ratings. Conditions can be present where V
OC
and I
SC
approach 1.25 times STC ratings which is why National Electrical Code
and our recommendations call for 1.25 derating of both V
OC
and I
SC
. Yet in real world conditions I
MP
actually seen is commonly only about 75
–
80%
of I
MP
at STC.

MOUNTING
➢
CAUTION:
The front panel may become quite warm to the touch during normal operation. Mount the 3000i
vertically to promote air flow and cooling, do not enclose in a confined space and avoid mounting in direct sunlight.
The 3000i is not watertight and must be protected from rain, snow and excessive moisture. Corrosion resulting from
liquid water or excessive moisture voids the limited warranty. An optional black powder coated deluxe mounting box
is available as BSE p/n 720-0011-01. The optional mounting box is the same X,Y dimension as the 3000i front panel
and 2.75” (7cm) deep.
