SMARTGRIDONE CONTROLLER GUIDE
Which SmartgridOne controller fits your project?
Compare Home, Light, Pro EDS, Pro OM1 and Ultra by application, project limits and physical connections. This guide uses the latest technical comparison from the Eniris webshop.
Good to know: controller hardware and control licences are separate products.
QUICK CHOICE
Start with the project type
Home and Light cover compact residential installations. Pro expands towards larger residential and commercial sites, while Ultra is designed for demanding C&I and utility applications.
Light
Network-first installations

Compare project fit
| Controller | Target users | Project limits |
|---|---|---|
| Home | Residential | Up to 5 devices, 40 A |
| Light | Residential | Up to 5 devices, 40 A |
| Pro EDS | Residential & commercial | No minimum power, up to 1 MW |

CONNECTIONS & I/O
Compare physical connections
Check the interfaces that must be available directly on the controller. This is often the deciding factor between Home, Light, Pro EDS and Pro OM1.
| Connection | Home | Light | Pro EDS | Pro OM1 | Ultra |
|---|---|---|---|---|---|
| RS485 inputs | 1× | 0* | 4× | 1× | 4× |
| Modbus TCP inputs | 1× | 1× | 1× | 1× | 3× |
| Digital inputs | 0 | 0 | 0 | 2× | 8× |
| Digital outputs | 0 | 0 | 0 | 2× | 8× |
| Relay outputs | 0 | 0 | 0 | 2× | 0 |
* SmartgridOne Light supports RS485 via an external RS485-to-USB converter.
FINAL CHECK
How to make the final choice
- 1Count the devices.Home and Light support up to five devices; larger or more complex projects move to Pro or Ultra.
- 2Check the grid connection and project power.Home and Light are intended for residential connections up to 40 A; Pro covers projects up to 1 MW.
- 3List every required interface.Count RS485, Modbus TCP, digital I/O and relay connections before choosing the hardware.
- 4Match control complexity.Use Ultra when many devices, demanding logic or time-critical control are central to the project.
