Control response time
When controlling assets (EV's, batteries), the Sofar EMS sends a command to the device, which then needs time to process this command and adjust its state accordingly. This is known as the control response time. The time needed for this, and the time it takes for the Sofar EMS to send a new command, depends on the following factors:
- The type of device (e.g., battery, EV charger, heat pump)
- The settling check
- Limitation on the RS485 bus
- The scheduler interval
When your Sofar EMS is active in ancilllary services, a fast response time is crucial. On this page, we will explain how these factors influence the control response time and how you can optimize it for your specific use case.

Key takeaways:
- Don't use Modbus-RTU (RS485) when having multiple devices connected to the RS485 bus. Use Modbus-TCP instead.
- Disable ramp-up and ramp-down settings on devices that support it, such as batteries and inverters, to allow for faster response times.
- Disable settling check, if you understand the implications.
- Set the scheduler interval to 1 second for faster command processing.
