Automatically limit inverter outputs based on grid excess with Home Assistant and OpenDTU

Here is my Home Assistant OpenDTU dsashboard:

I sometimes need to be able to limit by production excess around a number to avoid retruning too much energy to the grid.

So I did a Home Assistant automation that is looking at the grid_power sensor to automatically adjutst the inverters' limit in order to keep the returned powr at a specifed amount.

Zoom on the toolbar:

• Power limit: this is an input where I can type (in manual mode) a limit to apply to all inverters

• Auto Limiter: when off, I decide the limit. When on, the automation triggers each minute to adjust the limits automatically.

• Setpoint: this is my desired level of excess to stick around. There are 2 setpoint: when the limiter is on, and when it is off. If set to 0, there will be a little excess and consumption. Setting it to -400W for example let me return lieelt energy to the grid and also keep a buffer.

For examle here is today's result on a cloudy / sunny day, from 13h30 until 18h00:

Spikes of production or consumption trigger an adjustment. The adjustments take time to apply: around 10-20 seconds in my case. So I am running the automation each minute.

Putting that in place is super easy: just copy paste the input_number and automation sections from my opendtu config below.

You will need to adjust:

• sensor.grid_power => your grid power
• sensor.inverter_1_power, sensor.inverter_2_power, sensor.inverter_3_power, etc: your inverters power. Note that I am only using that to compute a more accurate available number of active inverters. You could replace that by the number of inverters you have, the correction will take more minutes to apply.

The file view.yaml is the Dahboard view

The file opendtu_3erl.yaml is to support automatic inverter limitation with 3ERL API. There is 2 setpoint values:

• Setpoint when 3ERL limiter is off
• Setpoint with Limiter: when 3ERL limiter is on
