 Note that this is part is setting the capabilities, not actually setting limits for the system to use. See [[#qwhy_does_the_system_exceed_the_configured_power|here]] for info on setting limits for the system.
+Then you need to set the operating mode:
+  * Green mode:
+    * Only sell surplus solar back to the grid after consumption and battery charging
+    * Energy in battery is reserved for consumption
+    * Charge battery when prices are low
+  * Trade mode:
+    * Always sells surplus solar back to the grid
+    * Energy in battery is used to trade
+    * Charge battery when it is beneficial for trading
+You can always adjust this mode at a later stage, so pick the one that best suits your needs.

 At the moment this is not possible. If we decide to add it, it will first be added to the [[https://flows.nodered.org/node/victron-dynamic-ess|Node-RED implementation]] first.
-==== Q: Can you give an example with calculations? ====

-Given a system at 15% SOC that has set the battery costs to 0.06 €/kWh, energy prices right now (11.00) set at € 0.29 and becoming € 0.40 this evening. Why would it feed into the grid already and not wait until the prices are higher?
-The battery cost is € 0.06 per kWh. This means that for a cycle of battery usage to be useful (financially beneficial) the price difference should be at least € 0.12 cents per kWh (€ 0.06 for charging, and € 0.06 for discharging). € 0.40 - € 0.29 is € 0.11 which is below that, hence Dynamic ESS does not want to use the battery for this task, instead it is offloading the excess to the grid.
