SKU: Y3-2M Bus Category:

Order requirement

APsystems Y3 cable is sold with QS1 and YC600Y inverters only.

APsystems 2-Meter Y3 AC Bus Trunk Cable connects the microinverters in a branch into a single output. Use it with YC600Y and QS1 microinverters.

The Y3 Bus Cable is a continuous length of insulated and UV resistant 2.5mm2 12AWG cable. Every 2 meters (~ 6ft), the cable features a pre-assembled connector plug for one microinverter.

When you are planning your layout, consider one connector for every microinverter. That is equivalent to every 2 solar panels when using the YC600Y inverters and every 4 panels when working with the QS1 units. Use the Y-CONN cap (sold separately) to seal any unused connectors.

Cable gauge: 12AWG
Cable diameter: 2.5mm
Maximum current: 20A
YC-2M length: 2 meters (recommended for YC600Y and QS1 )
3 internal wires including ground
Cable type: U-1000-RO2V (TC-ER)

The YC3 bus trunk cable comes in two lengths, depending on the PV layout (see video below):
– 2-meter for 2×1 YC600Y and 2×2 QS1 microinverter portrait layouts.
– 4-meter for the 4×1 QS1 portrait and landscape layouts.
