To Verify Data Monitoring Connectivity

Verify connectivity using the following information:

1. Check the status light located on the front of the communication PCB in the

card cage on the right side of the upper compartment in the data monitoring

section.

If the green status light is in a solid on state, the data monitoring connection is

established. If the status light is not solid, troubleshoot the connection.

2. Register the inverter at the AE Solar Energy web site to complete the setup for

monitoring the inverter.

The AE 500 inverter can communicate via Modbus/TCP or Modbus/RTU.This

chapter is written for PV installers, electricians, controls contractors, and Modbus

network programmers.

Modbus is a serial communications protocol and is the most commonly used means

of monitoring and communicating between devices in the PV industry. The Modbus

protocol allows for communication between a Modbus master device and multiple

Modbus slave devices connected to the same network. The physical layer for

Modbus/TCP is a CAT5 Ethernet network. Modbus/RTU uses a twisted pair shielded

conductor RS-485 network.

The following steps are required to set up a Modbus TCP network for your AE

inverter:

• Field installation : This step can be completed onsite by a PV installer or an

electrician that does not have working knowledge of a Modbus network
