Solar inverter
Modbus monitoring
Power, energy, operating state and alarms read directly from your inverters over Modbus, and delivered to your own platform next to the site meters and loads.
THE PROBLEM
Each inverter brand has its own portal, and none of them sees the whole site
Commercial and industrial solar sites often mix inverter brands, added in phases over the years. Each brand sends data to its own portal, with its own login and export format. Asset owners, O&M contractors and energy managers end up stitching reports together by hand.
Those portals also see only the inverters. They do not show the site import meter, the diesel generator or the loads, which are what decide whether the solar is actually offsetting grid energy.
Most string and central inverters expose their measurements over Modbus. Reading them locally puts every inverter, every meter and every load into one data stream that you control.
HOW WE SET IT UP
Inverter data on your terms
Confirm Modbus access per inverter
We check each inverter model for Modbus RTU or TCP access, and whether it needs a communication card or a setting enabled. The register map is confirmed before commissioning.
Inverters and meters together
The same gateway reads the inverters and the site energy meters, so generation, import and export are recorded on one timeline.
Alongside the existing logger
Where the manufacturer's logger already polls the inverters, we can read through it, use a separate port, or plan the bus so both coexist.
Delivered to your platform
Readings go to RIOD Live or straight to your own platform over MQTT with TLS 1.2, with API access for asset management or billing systems.
AT A GLANCE
Inverter monitoring in brief

FAQ
Questions buyers ask us
Can I read my solar inverter over Modbus?
Most commercial string and central inverters support Modbus RTU over RS485 or Modbus TCP over Ethernet, sometimes after enabling it in settings or fitting a communication card. We confirm access and the register map for each model.
Can inverters from different brands be monitored in one system?
Yes. Each inverter model gets its own register map in the cloud application, and the readings appear in one view with common names and units.
Can inverter data go to our own monitoring platform instead of the manufacturer portal?
Yes. The gateway sends readings to RIOD Live or directly to your own server or platform, and data can be passed on through an API.
Can we monitor solar generation and grid import together?
Yes. Site energy meters on the same RS485 bus or network are read by the same gateway, so generation, import and export share one timeline.
Want all your inverters in one place?
Send us the inverter models and the site meter layout. We will confirm the Modbus access and how the data reaches your platform.
