⚙How It Works
A data gateway concentrates the many protocols of a PV plant — inverter RS485, meter Modbus, sensor 4-20 mA — onto a single uplink to the cloud or SCADA. It buffers data locally so short network outages lose nothing, and it is the device that makes a fleet of mixed-vendor equipment appear as one coherent plant on the monitoring dashboard.
▦Structure & Composition
The gateway carries multiple downstream ports (RS485, Ethernet, digital inputs) and an upstream link (4G, Ethernet or WiFi). A local store buffers logged data, and a protocol engine translates between Modbus, MQTT and vendor-specific registers. It is DIN-rail mounted inside the plant cabinet, powered by a wide-range DC supply.

Applications
Selection Guide
- Choose the device capacity (up to 60 devices) to cover every inverter, meter and sensor on the site.
- Match the uplink to the site — 4G where no fixed line exists, Ethernet where it does.
- Confirm the gateway speaks the inverter and meter protocols before integration.
Frequently Asked Questions
What does a gateway actually do?
It concentrates many device protocols onto one uplink and buffers data locally, so the whole plant appears on one dashboard.
4G or Ethernet uplink?
4G suits remote sites without fixed lines; Ethernet is cheaper and more reliable where a network exists.
What happens during a network outage?
The gateway buffers data locally and re-syncs when the link returns, so no production data is lost.
