Smart DataLogger for C&I photovoltaic installations

GoodWe developed the EzLogger3000C for commercial and industrial solar projects where it is necessary to collect, process, and transmit information from numerous devices.

The datalogger acts as the installation’s central communication point, allowing information to be sent to cloud servers and monitoring platforms, while also enabling remote control and energy management functions.

Its ability to work with multiple protocols makes it suitable for projects where different equipment and supervision systems coexist.

Connection of up to 100 devices

The GoodWe EzLogger3000C supports connection of up to 100 devices, making it possible to centralize photovoltaic installations with a large number of inverters and auxiliary equipment.

This capacity is especially useful in commercial, industrial, and collective self-consumption solar plants where information from different devices needs to be concentrated in a single data acquisition system.

Four RS485 ports

The unit incorporates 4 RS485 interfaces identified as COM ports, providing different communication lines for connecting compatible devices.

Communication via RS485 uses the Modbus-RTU protocol, widely used in energy installations and industrial automation systems.

The availability of four separate buses makes it easier to distribute connected devices and provides flexibility in the design of the installation’s communications network.

Two Ethernet LAN ports

The EzLogger3000C features 2 LAN interfaces, allowing connection to Ethernet networks and to different supervision equipment or platforms.

Through Ethernet, GoodWe specifies compatibility with the following protocols:

• Modbus-TCP.
• IEC 60870-5-104.

These options expand the datalogger’s integration possibilities in energy management systems, automation, and photovoltaic installation monitoring.

Integrated 2.4 GHz WiFi

The device includes IEEE 802.11 b/g/n WiFi connectivity in the 2.4 GHz band.

GoodWe includes this connection to simplify local setup and maintenance tasks, offering an additional alternative to wired Ethernet connectivity.

Optional 4G

The manufacturer’s technical documentation also includes optional 4G communication, expanding connectivity possibilities in installations where conventional network infrastructure is not available.

The availability of this function depends on the specific project configuration and accessories.

Configuration via SolarGo and integrated web interface

The GoodWe EzLogger3000C can be configured using the SolarGo app and through an integrated web interface.

The web interface allows access to the device from a compatible browser to view data and perform configuration and maintenance tasks.

GoodWe highlights this dual option as a flexible way to commission and manage the datalogger according to the needs of the installer or photovoltaic plant operator.

Monitoring via SEMS and third-party platforms

The EzLogger3000C supports simultaneous monitoring via SEMS and third-party platforms.

This feature allows the GoodWe monitoring ecosystem to be maintained while also transmitting information to compatible external systems, providing greater flexibility in professional installations that use centralized management platforms.

Compatibility with different inverter generations

GoodWe highlights that the EzLogger3000C facilitates the parallel integration of inverters from different compatible models or generations.

This feature can be especially useful in expansions of existing photovoltaic plants, where new inverters must coexist with previously installed equipment.

Exact compatibility should always be checked against the current list of compatible inverters and devices published by GoodWe.

Data recovery with 30-day retention

The datalogger includes a data recovery function after interruptions, with retention of up to 30 days.

This functionality is designed to reduce information loss when a temporary communication interruption occurs and later recover the stored data.

Digital and analog inputs and outputs

In addition to its communication interfaces, the GoodWe EzLogger3000C includes different inputs and outputs designed to expand its integration possibilities within the installation.

• 4 digital inputs (DI).
• 2 digital outputs (DO).
• 4 analog inputs (AI).
• 1 PT100 input.
• 1 PT1000 input.
• Active output: 12 V, 100 mA.

These interfaces allow different compatible signals and sensors to be connected within energy monitoring and management projects.

Inputs for PT100 and PT1000 sensors

The datalogger specifically features one PT100 sensor input and one PT1000 sensor input.

These resistive sensors are commonly used for temperature measurement in technical and industrial applications, providing an additional monitoring option within the photovoltaic plant.

USB 2.0 port

The GoodWe EzLogger3000C incorporates 1 USB 2.0 port and is compatible with USB storage devices.

GoodWe includes this interface as support for maintenance operations, access to information, and device software updates.

Four LED indicators

The unit has 4 LED indicators that make it possible to visually identify different operating and communication states.

These indicators simplify installation, diagnostics, and maintenance by providing basic information directly from the datalogger itself.

Consumption below 15 W

The EzLogger3000C operates with a 24 V DC power supply and has a power consumption of less than 15 W.

The power adapter specified by GoodWe supports an input of 100 to 240 V AC, 50/60 Hz and provides an output of 24 V DC.

Different mounting options

The device offers several installation possibilities to facilitate integration into electrical cabinets, technical rooms, and other spaces intended for monitoring systems.

GoodWe includes the following mounting methods:

• Wall mounting.
• DIN rail mounting.
• Desktop installation.

This flexibility allows the datalogger to be physically adapted to the characteristics of each project.

Compact dimensions and reduced weight

The GoodWe EzLogger3000C measures 255 mm wide, 47.5 mm high, and 173 mm deep.

Its weight is approximately 0.8 kg, making it easy to integrate into technical cabinets or wall-mounted installations without requiring a large support structure.

Operating range from -30 to +60 °C

The unit is designed to operate at an ambient temperature between -30 and +60 °C.

For storage, GoodWe specifies a range between -40 and +70 °C.

The permitted relative humidity is between 5 and 95%.

Operation up to 5,000 meters altitude

The manufacturer specifies a maximum operating altitude of 5,000 meters, providing a wide margin for installations located at high elevations.

IP20 protection

The GoodWe EzLogger3000C has an IP20 protection rating.

For this reason, it must be installed indoors or inside a suitable enclosure that provides the additional protection required against dust, humidity, water, and other environmental agents when installation conditions require it.
