@dfaber in the old forum, I asked that the grid setpoint parameterized in the ESS also be taken into account for active DESS. In the spring of this year it was still ignored, and you replied as follows: In this case, as the ESS grid setpoint is known and we could use it, I did create an issue for …

Also -10W grid setpoint is working with DESS activated: [Screenshot_20240921_085738_Chrome] Conclusion: small negative grid setpoints such as -10 or -20W work in DESS, high negative values such as several minus hundreds or -1000W are obviously limited to significantly lower negative values. In my…

Beta firmware on MultiRS or Venus OS? Also grid setpoint on Multi RS? Do you have a firmware for Multi RS that can inject into grid?

I have now tested changing the grid setpoint in VenusOS 3.42 to -1000W in the ESS settings: DESS deactivated: grid setpoint is maintained DESS activated: grid setpoint is unfortunately still ignored I would like to have it set to -10W to prevent buying from grid as far as possible, which also wor…

It seems that DESS does take the grid setpoint into account within certain limits! Here last night with grid setpoint -20W. On average, there was actually always a slight feed-in: [Screenshot_20240919_075157_Chrome] I will now also test this with -10W.

Oh no, I accidentally deactivated DESS last night, i.e. the screenshot above with -20W is from deactivated DESS! I will now test this with -20W and DESS active and will report tomorrow!

Yes, it is coming to public in next weeks ( RS firmware )

I’ve been looking at the code. ESS setpoint does not seem to be used. In some scenarios "0" is hardcoded and in other scenarios it doesn’t use a setpoint directly like ESS does, but instead uses a very large setpoint along with a MaxDischargePower override which is calculated from pv output and con…

Ok this looks good! DESS active and grid setpoint -20W last night. On average, there was always a slight feed-in to the grid.

Next night I’ll try -10W.
