Cloud-Based Monitoring

Model Number: PLC Box, Data Logger, ComBox 1C, ComBox 4C
Monitoring for a PV system is a must, whether you are a homeowner, installer or utility. It is the most efficient and inexpensive way to troubleshoot and maintain a PV system, ensuring the system is at its optimal performance over the lifetime of the installation. It only makes sense that our monitoring system should be cloud-based for ease of access from anywhere in the world, through a web portal, an Android or iOS app.

Hardware
Data Logger and PLC BoxFor communication reliability, Darfon Cloud-based monitoring solution separates the communication before it reaches the service panel. The solution includes two hardware pieces: the PLC Box and Data Logger. The PLC Box is installed between the microinverters and service panel then sends information to the Data Logger. By bypassing the service panel, you avoid all the white noise and get a clean, stable signal. This latest generation of Data Logger incorporates WAN and GSM transmission for connecting to the Cloud.

ComBox 1CTo make installation faster and easier for our installers, Darfon’s ComBox prewires the Data Logger and PLC Box into a junction box that is simple to install. ComBox 1C is for one circuit PV systems, whereas, ComBox 4C is for larger installations with up to 4 PV circuits. With ComBox 1C, you just need to bring the grid tie and PV conductors into the box and land them on the quick connect terminals. With ComBox 4C, you will need to install the circuit breakers you need, then land the PV and grid tie conductors. Utilizing the 1C and 4C ComBoxes, you have all the advantages of separating the PLC communications from the noisy house circuitry without the complicated wiring.
