Background
 Why are photovoltaic (solar power) panel assemblies needed?
– cost effective alternative
– to provide power where or when line power is not available
– Other methods, eg generator, fuel cell, wind not practical
 Why is CCH offering?
– wireless I/O, also applications for lighting, instruments, sensors
 Why not just offer batteries?
 What is the difference between solar for ordinary locations and
for Division 2 hazardous locations?
 Key questions to select:
– what location to install? (ie how much sun?)
– what load, in amperes? (size the panel and the battery)
– how often will the load need power?

Battery Technologies
There are three (3) general types of battery
technologies that are used in photovoltaic (PV)
off-grid application
Flooded
AGM
Gelled
18
Battery Technologies
Flooded
19
Battery Technologies
Flooded
Most common in Home Power applications
Large size offering
Requires controlled environment
Non sealed system
Requires quarterly inspections to determine
electrolyte level and specific gravity
Less initial cost
20
Battery Technologies
AGM
21
Battery Technologies
AGM
Absorbed Glass Mat
Sealed system- All gases are recombined and
returned to battery system
Electrolyte is suspended in a glass mat
Large range of product sizes, many manufacturers
Confused often with a gel-cell
Lower cost and shorter cycling life than
gelled electrolyte
22
Battery Technologies
Gelled Electrolyte
23
Battery Technologies
Gelled electrolyte
 Designed for maintenance-free deep cycling
solar applications
 Sealed, valve-regulated, gelled electrolyte
 Low stand loss minimizes deterioration between
transport and storage
 Non-spillable ICAO, IATA, and DOT ratings
ensure safe transport without the need for
special containers
 Handles heat better than AGM or Flooded
Battery
• UL Listed:
UL1989
 Higher initial cost, heavier weight
Specifically designed batteries supply power to
the load when sunlight decreases or at night
24
Battery Technologies
Does depth of discharge affect cycle life?
Yes! The harder any battery has to work, the sooner it will fail.
The shallower the average discharge, the longer the life. This is why it’s
important to size a battery system to deliver at least twice the average
power required, to assure shallow discharges.

Sizing Solar Arrays
(4) Questions that your customer will be able to
provide the answer to:
1 - What is the power consumption expressed as
either watts or amps
2 - Duty-cycle…How long is the equipment
running, continuous, intermittent, etc.
3 - What is the equipment voltage, generally but
not always this is: 12VDC / 24VDC / 48VDC
4 - Where is the geographic location for the
system, different locations have different solar
resource values
29
Selecting a System
STEP ONE
Determine the equivalent sun hours
of the application you would like to
install a solar kit into.
Example:
Atlanta, GA  4.0 Equivalent Sun Hours
In case you are wondering,
Syracuse, NY …1.5 (ESH)
30
Selecting a System
STEP TWO
Determine the load requirements for your application in Amp-hours / day.
For wireless applications, determine the power of your device in amps
(for CCH wireless radio power consumption, refer to the calculator on our website:
http://www.crouse-hinds.com/wirelessIO/Calculator/Files/CCHSolarCalc.xls
STEP THREE
Determine the duty cycle (i.e. 100% for continuous vs. 50% for 12 hours per day) of your load.
STEP FOUR
Adjust for a 1.2 service factor to account for load requirement variability
STEP FIVE
Select the solar kit capable of meeting or exceeding the load requirements (in Amp-hours /
day) for your application.
Note: Assemblies for higher load requirements are available.
Load requirement (Amp-hours / day) = (amps of device x duty cycle x 1.2) x 24 hours / day
31
Selecting a System
Example:
200 mA device, continuous duty cycle, Atlanta GA
Load requirement = (200 mA x 100% x 1.2) x 24 hours / day = 5,760 mA-hr / day
Load requirement = 5.8 Amp-hours / day used in a region which has 4 equivalent sun hours
