C-Series PV input

Issue:

Customer is installing a C-series charge controller and wants to confirm the input PV voltage.

Environment:
 

C35
 

C40
 

C60


Resolution:

C35 - Voltage Configuration 12V 24V Maximum PV Array Open Circuit Voltage 55V

C40 - Voltage Configuration 12V 24V 48V Maximum PV Array Open Circuit Voltage 125V

C60 - Voltage Configuration 12V 24V Maximum PV Array Open Circuit Voltage 55V


Cause: THESE MAX VOLTAGE LIMITS ARE NOT TO IMPLY THE C-SERIES BEHAVES LIKE MPPT, BECAUSE IT DOES NOT.
ARRAY VOLTAGE MUST BE CONFIGURED FOR THE SAME VOLTAGE AS THE BATTERY FOR MAXIMUM EFFICIENCY.
