Step 8. Connect Apsystems Microinverters To Grid; Step 9. Ac Extension Cable; Step 10. Complete The Apsystems Installation Map - APsystems DS3D Quick Installation Manual

WARNING: Each PV panel must be carefully connected to the same channel.
Make sure to not split positive and negative DC cables into two different input channels: microinverter will be
damaged and warranty will not apply.
NOTE: Each channel connects 2 PV modules in series (For PV modules with Voc<60V).
The input channel will not work if connects to a single module(Voc<60V).
That means the quantity of PV modules in the sysem is even number.
NOTE: Remove the DC
connector caps before
PV modules connection.

Step 8. Connect APsystems Microinverters to Grid

NOTE: 1.Please install bi-polar circuit breakers with proper rated current or according to the local regulation,
which are mandatory to connect to grid.
2.Leakage current breakers or AFCI/GFCI breakers are not recommended to install.

Step 9. AC Extension Cable

When AC extension cable is needed, users could connect the AC bus cable and AC extension cable in a junction box
or use a pair of male/female AC connectors that APsystems provides as optional accessory.
