2.0 INSTALLATION
AC Circuit Breakers:
The main service panel must dedicate a 15 amp minimum, double pole breaker (120/240 volts
AC) to operate the ST unit.
Wire Routing:
Determine all wire routes both to and from the Sun Tie. Possible routing considerations include:
•
AC input wiring from the main service panel to the ST
•
DC input wiring from the PV array to the ST
•
DC ground from the PV array to an external ground rod
•
All wiring and installation methods should conform to applicable electrical and building codes.
•
Pre-plan the wire and conduit runs. The DC terminal blocks accept up to a #6 AWG wire; the
AC circuit disconnects accept cable sizes up to #1 AWG.
•
For maximum safety, run both AC and DC wires/cables in (separate) conduits.
WARNING: CHECK FOR EXISTING ELECTRICAL OR PLUMBING PRIOR TO DRILLING HOLES
IN THE WALLS!
