German EEG §9 requires to reduce feed in power by DNO for all installations up from 7kVA in 4 steps 100/60/30/0%. (See Multiplus FW update v555) Older Installations before February 2025 receive a compensation pay for assumed power within this throttled time. New installations after Febraury 2025 a…

You may have to create a node red solution.

My Node Red solution for power limiting is here . It already works like expected. To trace a complete year, tools like VRM using visualisation and database seems to be prefered. Its simply to see the voltage level of inputs instead counts. Maybe I have to connect analog inputs in parallel to achieve …

Thanks for the link. I trigger the function every hour with an inject node, but you can chose the frequency you want to log. Be careful though as a higher frequency will generate a lot of data. To record the throttle times, log frequency of one minute seems appropriate. For one year, this will p…

Aha. Does it switch that often? I would just record changes and a timestamp. I only see 16 or so switches changes there per input. How long was it running?

For the moment, the control device supplied by DNO is not connected. They like to see the functionality first to make sure the power limiting works like required by their rules. I have no idea, how much they use those throttle signals. What I heard from some DNOs that they never used. In Bavaria th…

Janvi, afaik, the will use 2 relais-outputs for a 2 Bit signal. HL State 00 0% 01 30% 10 60% 11 100% Best, Wilm

This is a proposal by VDE from last year to use one of the remaining outputs for the new EnWG §14a what is the use case LPC limitation of power consumption. Obviously the DNO cannot change their existing devices and control signals needs to be same for everybody. The Royal Air Force in 2nd world wa…

Janvi, what has an Azon guided bomb to do with §9EEG or §14aEnWG? Never, and I mean never, try to compare anything, especially with me, with the Nazi-regime. My family was deported from Bohemia. But, If your DNO still stays with the good old German Rundsteuerempfänger instead a real control-box …

I deleted my last 4 words but before and after, it remains still a comparison of signals and not of countries or ideologies. The new and hardly available FNN-Steuerbox also works with 4 relais contacts. The danger of manipulation is that somebody else than the DNOs will control the power of all inv…

Maybe. I haven’t tried. In node red i am working on a flow to log run/closed time. Was thinking maybe something like that?

An adaptation of this idea.
Using the closed and open status.
