How do I use a dual optimizer (2ES) on a single module?

If your system has an odd number of modules per string, you can use a dual optimizer (2ES) on a single module by connecting the pair of leads marked Input A to the module, and connecting the pair of leads marked Input B to each other.

Input A is the shortest pair of input leads.

A 2ES bar code will automatically fill in serial numbers for a pair of modules except on the last module in the string. If using a 2ES on a single module anywhere else in the string, remove the automatically entered number (beginning with 881-) before scanning your next bar code.

 

When replacing or changing a serial number in the configuration wizard, there will be a prompt asking whether you want to update the following serial number or leave it alone. If using a 2ES on a single module, click "Leave it alone."
