APPENDIX PV MODULE SELECTION
Find the following PV panel parameters first, and calculate to see if it meets the product's acceptable
spec range (See Technical Specification section).
PV Panel Parameters
Pmax
Vmp
Imp
Voc
Isc
Please consider below requirements:
(a) Total Voc < Product's max. PV input voltage
(b) Vmp falls within Product's optimal operating voltage range
If one PV module cannot meet this requirement, connect multiple PV modules in series to
increase the total voltage.
Example for CPD1200EO12LCD
After considering Voc of PV module not exceeds 40VDC and Max. Vmp within 15~18VDC, we can
choose PV module with below specification.

Example for CPD2200EO24LCD
After considering Voc of PV module not exceeds 55VDC and Max. Vmp within 30~36VDC, we can
choose PV module with below specification.
