The trunk cabling portion of a microinverter system is extremely important since it directly impacts labor costs at an installation site. The Chilicon modular trunk and branch cabling system incorporates industry standard 10 AWG VNTC tray cable with a UV and cut resistant outer jacket. Each 'modular' component of the 4 conductor cableplugs together right on the job site. For the first time, you can mix landscape and portrait mode PV module layouts side-by side on the same string. In addition, the trunk cable is 'Self-Terminating' as shown in the figure below. There is no longer a need to procure 'termination caps' for the end of each microinverter string.
The trunk cable's 10 AWG cabling enables use of 30 A OCP devices (typically a 2 pole circuit breakers). This means that 20 CP250e devices running 289W output can be wired on a single 30 A string in 240V split phase mode, or 18 CP250e devices running 277W output can be wired on a single 30A string in 208V three phase mode. In the case of the 720W output, CP-720 device, 8 inverters (16 modules) can be wired to a 30A breaker in 240V split phase mode, or 7 inverters (14 modules) in 208V three phase mode. See the CP-250E Datasheet or the CP-720 Datasheet for detailed current and voltage scaling information.
