Conext XW PRO 6848 6,800W 48V Installation

Overview
The Conext XW Pro digital communications interface with the Conext Gatewaysupports
commands from external equipment to control power output and operational modes,
which allows support for industry-accepted communication standards SunSpec Modbus
and IEEE2030.5.

SunSpec Modbus
The Conext XW Pro supports the following data models from the SunSpec Modbus
specification via the Conext Gateway.
SunSpec Model Name Description
Model 1 Equipment Identification
Model 102 Split-Phase Inverter Monitoring
Model 121 Basic Settings
Model 123 Immediate Controls
Model 124 Storage Controls
Model 20001 Inverter Custom Model
Power Limiting
Externally-controlled power limits are applied at the AC transformer at the inverter output
prior to connecting with the AC bus. During Selling, Conext XW Pro arbitrates between
all sources of power limitation, including externally-controlled limits, by taking the
minimum. If the system receives a lower power request than what is currently in effect,
the Conext XW Pro will control power flow to the new limit.
Similarly, during Peak Load Shaving, the lower of Load Shave Amps and the externally-
controlled limit minus the load power is taken.
Communications Loss
Communications with the SunSpec Controller is continuously monitored. When a
communications loss with either the Conext Gateway or the SunSpec Controller is
detected, the Conext XW Pro supports the following configurable responses via a
