Photovoltaic (PV) modules generate electricity when exposed to light. Modules pose a
shock hazard and risk of serious injury or death if instructions and safety precautions are
not followed carefully. Cover the glass faces of the modules with opaque material while
working on the system to stop the production of electricity. Avoid touching the terminals
and isolate wire end until all connections are complete.
Batteries can explode or severely burn if the terminals are shorted to the opposite polar-
ity. A single point system ground is required per NEC A.690. It is recommended to tie the
battery negative (-) terminal to the equipment chassis at the time of installation. Always
observe proper polarities when making electrical connections to the modules, batteries,
and controller.

3. For all connections use correct interconnect cables and tray cable (see gure right).
Note: Congurations on the right are with 12V modules. For 24V modules the array volt-
age will be double the value shown for the conguration.
Tray Cable Conduit
For more than two strings, use a combiner I/O Panel and refer to
the diagram included with the panel for wiring instructuions.

Battery Wiring
For 12V systems
Each 12V battery is in parallel with the next. Connect the RED jumper from BAT 1 POSITIVE (+)
terminal to the BAT 2 POSITIVE (+) terminal and the BLK jumper from BAT 1 NEGATIVE (-) terminal
to the BAT 2 NEGATIVE (-) terminal. Repeat this pattern for each battery.
For 24V systems
Each pair of 12V batteries are in series and form one string. Connect the BLK jumper from BAT
1 NEGATIVE (-) terminal to the BAT 2 POSITIVE (+) terminal. Repeat this pattern for each series
string.
Each series string must be connected in parallel to complete the bank wiring. Connect the RED
jumper from BAT 1 POSITIVE (+) terminal to the BAT 3 POSITIVE (+) terminal, and the BLK jumper
from BAT 2 NEGATIVE (-) terminal to the BAT 4 NEGATIVE (-) terminal. Repeat this pattern foe each
parallel pair.
For 48V systems
Each quadruple set of 12V batteries are in series and form one string. Connect the BLK jumper from
BAT 1 NEGATIVE (-) terminal to the BAT 2 POSITIVE (+) terminal, BAT 2 NEGATIVE (-) terminal to
the BAT 3 POSITIVE (+) terminal, BAT 3 NEGATIVE (-) terminal to the BAT 4 POSITIVE (+) terminal.
Each series string must be connected in parallel to complete the bank wiring. Connect the RED
jumper from BAT 1 POSITIVE (+) terminal to the BAT 5 POSITIVE (+) terminal and the BLK jumper
from BAT 4 NEGATIVE (-) terminal to the BAT 8 NEGATIVE (-) terminal. Repeat this pattern for each
parallel pair.
Final Connection
Inside the control/battery enclosure, connect the controller RED BAT (+) wire to the battery bank
POSITIVE (+) terminal. Connect the controller BLK BAT (-) wire to the battery bank NEGATIVE (-)
terminal.

I/O Panels
For I/O Panel wiring, refer to the diagram provided with the panel.

Conrm all connections, ttings, and fasteners are secure and the PV array
surface is clean and facing South.

24V systems 42VDC (open circuit voltage)
48V systems 84VDC (open circuit voltage)
Measure Voltages (Conrm all breakers are o󰀨 before measuring)
Measure PV array voltage from the PV(+) terminal to the PV(-) terminal in the
enclosure.
Measure battery voltage from either the BAT(+) terminal block to the BAT(-)
terminal block or the BANK(+) to the BANK(-) to verify that they are approximately:
12V systems 12-13V
24V systems 24-26V
48V systems 48-52V
Set breakers to the ON (closed) position
On the charge control panel
1. Set the BAT(+) CB2 input breaker
2. Set PV(+) CB1 input breaker
3. Set the LOAD (+) CB3 output breaker
Conrm that the controller status LEDs function properly.
On the charge control panel, measure the voltage from the LOAD(+) ter-
minals to the LOAD(-) terminals which should be the same as the battery
voltage.
Verify both the PV and battery polarity is positive. If negative, reverse wiring
to the system and check again.

6Connect Your Equipment

For optimum performance, your PV array should face true south in the Northern Hemisphere (and true north
in the Southern Hemisphere). However, when determining direction using a magnetic compass, indicated
bearings will vary from true bearings because of the di󰀨erence between the location of the true and magnetic
north poles. This angular di󰀨erence varies with location on the globe and is called the “declination.”
• Locate your using the web site below. (Great accuracy is not critical).
• Using the magnetic declination from the web site calculate true South. For example, the declination for
Washington, D.C., is
Approximately -11º; for Chicago, IL, -3º; and for Los Angeles, CA, +14º.
• Determine magnetic south at your site using a magnetic compass.
• If the local declination found in step 2 is negative, true south is that number of degrees added to
magnetic south. For example, at Washington, D.C., true south is the same as 180º + 11º = 191º
indicated. If the local declination found in step 2 is positive, true south is that number of degrees
subtracted from magnetic south. For example, at Los Angeles, true south is the same as 180º –
14º = 166º indicated.
• Orient your array in the direction of true south (or north if applicable) as determined above.
• The Internet site http://www.ngdc.noaa.gov/geomag-web/#declination will calculate magnetic variation from an input
of latitude and longitude, or Zip code.
For optimum performance, your PV array should set to a specic tilt angle. To determine the desired tilt angle
of the array, us the latitude from step one above.
Take this value and add the factor based on the table below. This will provide the optimum worst
case performance with the minimum amount of annual adjustment, based on the winter months
(Northern hemisphere).
Latitude range between 90 – 45° SET TO 60°
Latitude range between 40 – 25° +15°
Latitude range between 25 – 15° +5°
Latitude range between 10 – 0° SET TO 15°
