RS485 Communication

Advantages of RS485 Communication

The RS485 communications technology, as a widely used industry standard, provides efficient monitoring of PV-systems over long distances and in areas with strong electrical interference.

The micro-inverters are equipped with two RJ-45 connectors and can be used in conjunction with a data logger to monitor the performance of the PV-system. The installation of the system is easily carried out using the Plug & Play connectors.


Set-Up of a RS485 Micro-Inverter Systems

Each micro-inverter is connected to one or two PV-modules using the DC wiring. The DC power is individually converted into grid-compliant AC power. With the RS485 communication version, the converted AC power is then directly fed into the utility grid via AC wiring. The inverter is equipped with two AC terminals on the right side of the connection area. The inverter has two AC connectors. The AC connectors are polarized differently, so that multiple inverters can be connected to form a continuous AC power circuit.

To enable communication and monitoring, the micro-inverters are additionally equipped with two RJ-45 connectors, with which the micro-inverters are connected to each other and then either to the AEDL-LAN Data Logger, the AEDL-UH Data Logger, the USB-RS485 Interface Adapter, or to a building management system.
