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…

[image] dognose: [image] ndrew: Can you suggest how where I might look for more diagnostics? You could probably turn of DESS, when you have a battery capable of full charge and check two things: What happens when you set a grid-setpoint of 8000 + consumption, when there is no Solar? (Ex…

Hi Auke, I think I have the same issue, and a similar configuration. I have been googling and checking quite some threads, but until now I did not find a correct and hopefully easy solution, to switch off the Smartsolar RS 450/100 during negative prices. I see all kinds of solutions like HA or NodeR…

Yes, I installed more batteries. The batteries now can not be fully charged in the short time the prices are negative. So, it is no problem the PV is helping to charge them in that period.

I also have a large battery that cannot be fully charged during negative energy prices, but I would really like a solution to be developed that allows you to configure SolarEdge via Modbus to pause charging. I have three MP2-5000s and would like to see the charging capacity fully utilized based on g…

Hi all, Dynamic ESS will soon have a feature to turn off solar during negative sell prices. Will keep you posted :slight_smile:

Great, sounds really good! Question (or idea), how will this be implemented? I see two options: Hard switch off all solar Dynamic curtailing based on maximising grid import, though still maximise charging of the battery. This would enable for example still charging of car / run heatpump in parall…

Thats great news Barbera, thx for responding
