SMART PORTS
Smart ports are designed to power smart loads or accept AC-coupled inverter inputs. They are
controlled by an internal relay configured in the EG4
®
Monitor Center. Each port can also be manually
switched on or off using the breaker. Each smart port is individually configured and has different load
specs, as outlined in the table below.
When using the smart ports configured for smart loads, the attached devices can be powered on or off
according to grid presence, Time of Use (TOU), battery State of Charge (SOC/Voltage), and PV state.
When using the smart port with an AC-coupled inverter, additional power can be injected into the ESS
system from the PV array connected to the inverter.
Reference the tables below for wire size and torque recommendations depending on the type of wire
and connection.

NOTE
When operating a hybrid inverter with the GridBOSS, smart port functionality is moved
from the hybrid inverter to the GridBOSS. All devices that connect through a smart
port must be cabled directly to a GridBOSS smart port. Select GridBOSS in EG4
®
Monitor Center when configuring a smart port.
