We are happy to introduce a new feature in Dynamic ESS that allows you to better align with the specifics of your energy contract. Some energy contracts set energy prices to ‘zero’ when they go negative, preventing customers from profiting from negative buy prices. If your contract includes this con…

Awesome! please consider that some systems are not able to be integrated with victron, but for example i turn my enphase solar off with another system. Please please please add an option that DESS just considers solar production to be 0 kwh if the prices are below 0

I had a similar issue where SolarEdge shuts off the Solar production and DESS is not charging energy with negative prices from the grid.

Is there a list that shows which PV inverters (brand / type) are supported. Those should use the modbus / sunspec. I am mainly curious for GroWatt inverters. I see a interesting github for this type inverters: [image] GitHub - mahoekst/SunspecModbusServer Contribute to mahoekst…

Hi Barbara, I would like to see the option to have solar turned of during negative BUY prices (not sell prices) during negative sell prices I can put solar to my battery, and DESS will limit my solar inverters already (Via modbus) so that’s covered, however I noticed it’s not turning of solar duri…

[image] Help needed - SMA, Solar Edge, Kostal and others Venus OS beta testing Hey all, Per Venus OS, v3.60 now in beta, more PV Inverters (SMA, SolarEdge, Enphase, Kostal and others) can be controlled by a GX device. Rather than just monitored/read-out. Unti…

Hi, You are right, that was my mistake: this is indeed for buy. However, also for sell once your battery is full and there are no loads to use solar for.

What would be the difference with the current behaviour for negative sell prices ? When sell prices are negative and there is no load to put solar to DESS is already curtailing my 2 SMA inverters and victron solar charger ? (Even though the sma page on the documentation claims this doesn’t work) th…

Hi, is there an update on the ETA of this fuctionality? Currently the managing of my solaredge by victron doesn’t allow me to use home automation to shut down the inverter because victron overwrites it within seconds. I would love this feature not to have to do it manually anymore.

Hi Mathijs, Yes, this functionality is now in an internal test version of the GX software. I expect it to go to public beta this month.
