1. Introducing Cooper Crouse-Hinds Solar Power!

2. Solar Power • Background • What is it, how does it work • Component functions, ratings, certifications • Information needed to select • Competition • Product info, pricing, lead-times, tech support

3. 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?

4. Terminology • Off grid: solar power with battery backup • Grid tie: tied into utility power • Stand-alone: large (KW) solar power assembly • Hybrid: standalone coupled with generator • Inverter: electronic equipment to convert DC voltage from solar to AC for load

13. Mounting Structures • Roof & Ground Mount • Rapid Rac

14. Mounting Structures • Top of Pole • Single module • Multi module

15. Mounting Structures Side of Pole • Single module • Multi module

16.

17. 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 • Higher initial cost, heavier weight Battery • UL Listed: UL1989 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. Typical Battery Cycling Ability vs. Depth of Discharge Typical Life Cycles Capacity Withdrawn Gel AGM 100% 450 150 80% 600 200 50% 1000 370 25% 2100 925 10% 5700 3100

27. Catalog Numbering Logic

28. 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
