Chilicon Power Residential Design and Installation Guide

Module Layout and Orientation: The three standard length MTC cable sections make for easy deployment
in either portrait or landscape mode for either 60, 72 or 96 cell modules for the CP-250E, placing one
microinverter per module. However, the layout and cabling using the CP-720 dual microinverter requires
additional planning. Use of modules with DC leads shorter than 1.2m long can significantly complicate the
layout and may require the use of additional DC jumper cables, which Chilicon Power strongly discourages. The
most efficient layout is usually even rows of PV modules facing each other such that both sets of MC4 DC cables
can easily connect to one microinverter. This and other common configurations are described in the Chilicon
Power
“Cable Guide
” located in the appendix. Chilicon Power highly recommends reviewing it to determine the
optimal layout and cable lengths needed during project design.
2.4 Compatibility
The CP250E model is compatible with both 60-cell and 72-cell PV modules.
The CP-720 model is compatible with 60, 72, 96, and 128 cell modules.
All microinverters come with TI-Lane MC4 DC connectors. The connectors are a recognized component, tested
by UL (certification file number E347414). Other connector options may be available as specials.

2.6 Microinverter Marking
The microinverter label contains the company name and logo, operating parameters, safety warnings, and the
unit serial number. The serial number identifies the batch or production date of the device. Chilicon Power
recommends making an installation map showing the location of all inverters on the site. A second, peel-off serial
number is included to facilitate marking the project site map.
