WIRING FOR COMMUNICATION TO THE GATEWAY (240 V SPLIT-PHASE SYSTEMS)

Chilicon Power trunk cables have 4 color-coded conductors: RED, BLACK, , GREEN

BLACK and conductors are for the PLC communication. The same grid line (BLACK) must

be used to connect the inverter to the Gateway to ensure robust communication. Specifically,

the Gateway inside the home (120 V) should be powered using GRID HOT LINE B (= BLACK

trunk conductor) and GRID NEUTRAL (= trunk conductor).

NOTE: Communication with the Gateway is usually fine even if the Gateway is connected in the

wall socket to the RED and trunk-equivalent wires. However, the signal will be weaker.

The Gateway socket survey screen (Menu->Advanced Settings) indicates the strength of the

signal. In the worst case, you simply have to swap the RED and BLACK trunk wires on the

breaker or at the AC disconnect.

NOTE: Miss-wiring AC grid lines to the inverter trunk (for instance swapping a GRID L1 for GRID

NEUTRAL) will not damage the inverters. However, they will not export power in this

configuration. If inverters are miss-wired, LED single blink export confirmation from the LED will

never be established.

WARNING: NEVER CONNECT GREEN to a Live Wire
