Photovoltaic low voltage inverter communication box

What is a PV communication box?

Network infrastructures of PV systems are very heterogeneous. PV Communication Boxes are the link between the various network components. They ensure that data is reliably bundled, converted, and forwarded. Our PV Weather Stations are the interface between weather sensors and the plant monitoring and deliver data to maximise the energy output.

Why should you choose a PV communication box for ground-mounted PV systems?

Our PV communication boxes for ground-mounted PV systems are delivered ready for use and can be individually adapted to the communication infrastructure of the respective PV system. This guarantees optimal data acquisition, which has a positive effect on the function and economic efficiency of the plant.

What is a PV retrofit combiner box?

The installation of our PV retrofit combiner boxes makes it possible to obtain data at string level in PV systems with existing, unmonitored PV DC combiner boxes. All without additional work such as trenching and cabling. Wireless communication simplifies installation and avoids additional costs or maintenance work on the communication cables.

How does an inverter communicate with a monitoring platform?

The communication between the inverter and the monitoring platform relies on a communication protocol in terms of software and mainly uses a monitoring stick module as a medium or bridge for data transmission and reception in terms of hardware. This ensures that the inverter’s operation can be displayed on the monitoring and maintenance platform.

What communication methods do micro inverters use?

This ensures that the inverter’s operation can be displayed on the monitoring and maintenance platform. The mainstream micro inverter manufacturers in the global market primarily transmit and control data through communication methods such as WiFi, PLC, RS485, Sub-1G, and Zigbee. Below is an overview of each brand’s communication methods:

How does a micro inverter plc work?

The PLC module converts the operational data sent by the micro inverter into high-frequency signals through power lines and transmits them to the PLC receiver through the power grid. The receiver then connects the data to the router through a network cable, thereby connecting to the user’s device. No additional wiring is required.
