   * Note that there is no AC sensor necessary, since the inverter/charger will act as a 'dumb' bi-directional inverter/charger. It will act on the external command given, which can for example be 'take 2000W from AC in, or feed back 100W through AC in'.
-Available control points include the switch (on, charger-only, inverter-only, off), a power setpoint in Watts: regulates the power on the ac-input, and more.

+=== Mode 3 with a managed battery ===
+When using Mode 3 with a managed battery, please note that the maximum discharge current sent by the battery will be ignored. The implemented control loop should take care of discharge limits communicated by the battery.
+The exception to the above rule is a zero discharge limit. If a managed battery requests a zero discharge limit, the Multi will stop discharging the battery.
+    * If grid power is available, the Multi will go into passthru.
+    * If grid power is not available, the Multi will switch off.
+The maximum charge current sent by a managed battery is however always heeded and cannot be overruled by the setpoint.
