To commission multiple solar charge controllers:
1. Close the DC disconnect or use a selector switch to apply battery power to
all of the solar charge controllers at the same time.
The LCD on each unit displays the two startup screens in sequence, as
shown in Table 2-4, followed by a prompt screen for you to set the device
number.
2. On all the charge controllers, set the device number to a value other than its
default value of 00. No two charge controllers can have the same device
number. The device number can be set to any number between 01 and 31.
For the first solar charge controller, 01 is recommended. If you have two
charge controllers, simply set them to 01 and 02.
After setting the device numbers, a “Copy Config?” prompt screen appears
on all of the solar charge controllers. The options available are “Yes” and
“No”
3. On the solar charge controller you set to device number 01, select “No.”
You will be prompted to enter (as described in steps 2 through 9 in
“Commissioning a Single Unit Without a System Control Panel”):
• Battery connection. The default is Bank 1, and each solar charge
controller connected to a common battery bank must be set to the same
battery connection.
• Battery voltage
• Battery type
• Battery capacity.
4. The first unit will now have the minimum configuration settings confirmed. If
you want to customize other more advanced settings (such as 2-stage or 3-
stage charging, or custom battery type settings), it is recommended to do
that now as these settings can be automatically copied over to the other solar
charge controllers that are yet to be configured.
5. On the next solar charge controller, which should still be displaying the
“Copy Config?” prompt screen, select “Yes.”
Note
: If it is necessary to reset the solar charge controller to factory default
settings, checking that the device number has reverted to 00 will confirm the
reset was successful.
