This is the trunk cable for your APSystems YC600 & QS1 Micro Inverter system.
This 2 meter (6.5 feet) trunk cable will link the AC output from each of your YC600 or QS1/QS1A micro-inverters. 2m between connections, priced per connection.
The number of trunk cable connections is determined by the number of inverters you have on the string. Normally YC600 strings have a maximum of 12 solar modules (6 inverters), while the QS1 allows up to 3 inverters, or 2 inverters in the case of the QS1A.
The Trunk Cable should enter a suitable rail-mounted junction box, or roof-flashing junction box for transition to home-run AC wiring. Each trunk cable string should be terminated at the non-service end of the cable with an AC Bus End Cap, and any unused trunk cable connectors can be plugged with an AC Bus TCONN Caps.
To unlock the micro-inverter’s connector from the AC Bus Trunk Cable a Connector Unlock Tool is needed (although it is possible to do with fine screwdrivers & manual dexterity).
