Features of the Enphase Energy ET3C-G2-06 AC Trunk Cable with 3 Drops for D380 Inverter - 208 VAC

D380 TwinPack Trunk Cable
The D380 TwinPack cable assembly is constructed with a 12 gauge trunk cable and three "drop" cables at the inverter locations. The drop cables are spaced at two module-wide intervals. TwinPack cable assemblies are connected end to end to create a branch circuit of the desired length. Dimensions of the cable assembly are shown below in inches.

  

The 12 gauge trunk cable would be protected with a 20 amp circuit breaker allowing up to 33% more power per branch circuit, compared to branch circuits of the M190 and M210. A single 20 amp branch circuit would allow for up to 10 D380 TwinPack microinverters (20 PV modules) at 240 Vac, or 15 D380 TwinPack microinverters (30 PV modules) at 208 Vac. Different models of trunk cable are used depending on whether the installation is 240 Vac or 208Vac.

  • ET3R-G2-06 green label trunk cable is used for 208 or 240 Vac single phase
  • ET3C-G2-06 blue label trunk cable is used for 208 three phase installations.

 

Installation
The D380 TwinPack cable assembly has been designed with 3 inverter tap cables spaced at 2 module wide intervals. Twinpack cable assemblies would be connected end to end to create a branch circuit of the desired length. The twinpack cable assembly is then fastened to the module racking. D380 twinpack microinverters mount to the module racking below one of the associated PV modules.

For PV modules installed in landscape orientation, the D380 twinpack microinverters could be mounted to the vertical module supports. The spacing between inverter taps is intended for 2 rows of PV modules.

    This table provides detailed information on the possible branch configurations and the number of end-caps and single-drop cables that would be needed.
