Hi, I have performed simulations for Brazil of solar farms. One of our strategies would be to charge the battery only with clipped power energy. The clipped here occurs practically every day. In the "manual dispatch" option, the system also charging BESS in the "clipped energy power" moments outside. So, I thought about the following options:

1 - Use the manual dispatch with Brazil's respective times (This is already able to do). However, I need to put a rule to only charge the BESS with clipped. How do I do that?
2 - In the dispatch look-ahead option, I can impose the rule. However, I can't change the time I want BESS not to work (3 pm to 6 pm).

So, how can I change the manual dispatch to insert the rule of only loading with clipped? Or, how can I order the dispatch not to work from 3 pm to 6 pm?

Thinking about new markets, this option in software would be interesting. Thanks for your work!

Note that "clipped power" is not the correct term here. Clipping happens when the inverter clips the input voltage to its maximum or minimum rated input voltage. Power limiting happens when the inverter DC input power exceeds the inverter rated power. The battery algorithm currently charges the battery with power that would otherwise be lost due to power limiting rather than due to voltage clipping.
