Forecast based charge management ? CCGX und Multiplus 2




Is it possible to run a forecast based battery management? Considering Geo data, weather, ... The goal is loading the battery not in the morning - but e.g. at noon ..


--


In Deutschland , genauer gesagt in Berlin, gibt es Fördergeld wenn man einen Prognose basiert es Lademanagement umsetzt, die Idee ist den Akku nicht schon morgens direkt aufzuladen bei den ersten Sonnenstrahlen, sondern erst am Mittag , wenn Höchstleistung (PV) anliegt .. Auf diese Weise kann man eine gleichmäßige Einspeisung erreichen. Prognose basiert, heißt auch nach dass man Geokoordinaten mitgibt und eventuelle Wetterdaten berücksichtigt .. Es gibt ja die Möglichkeit über external Control eigene Steuerungen zu implementierenmentieren, hat das mal jemand versucht?

Hi @ rainer2407

translation of your question to English:

In Germany, more precisely in Berlin, there is a subsidy if you are using a forecast, the idea is not to charge the battery directly in the morning with the first rays of sun, but only at noon, when maximum power ( PV) is applied. On this way you can achieve a uniform feed. Prognosis is based, which means that geo-coordinates and weather data are taken into account.

--Answer:

No this is not possible with standard Victron software currently, you'll have to use an external EMS for this, maybe https://www.smart1.eu/ can do this? they can control Victron systems.

This is an interesting request, as I see a commercial benefit especially with a feed-in limit > 0 and < 100% of the PV power - which is quite common in Germany. And technically it also makes sense to reduce the peak load from PV feed-in for the grid stability.


Is there any plan to add this in an upcoming firmware of the GX?
