Making adjustments like this would be best to have a review by our support team. Reducing the global AC output of the inverter involves a thorough understanding of the installation site and the overall goals for the system. To determine the best course of action,
we’ll need to gather some key information, some of these questions would include:</div>

Depending on the site’s purpose and configuration, different approaches may be more suitable. Some customers benefit more from setting a max A discharge rate, using the load limit power setting (if supported by the inverter firmware), or receiving a command
to reduce the global AC output.</div>

Each option has specific requirements, and in some cases, these changes may have a permanent effect on the inverter. That’s why it’s critical for our team to fully understand the setup before recommending a solution. </div>

If I understand the question correctly, you can use Time of Use to set the maximum charge or sell power in watts for up to 6 time slots. I believe this will limit only the battery charge or discharge rate, however. I don't believe this will limit the total
input (loads plus battery charging). You can limit the total sell power with the Grid Sell feature in the System Work Mode settings. The Max Sell Power should limit the total solar export plus battery selling to this setting. </div>
