-==== Err 74 - Phase overload ====
+==== Err 74 - Too many units in parallel ====
 Applies to Inverter RS and Multi RS models. Firmware versions 1.12 and higher.
 The number of inverters in parallel doesn't match with the transfer capabilities of the ac input relay of the Multi RS or Transfer switch.
-Firmware v1.12 does not support parallel units and a grid connection, so any combination of a Multi RS with a grid connection with more than one unit in parallel will trigger this error code on the Multi RS. The Multi RS only supports 3 units in 3-phase configuration at the moment.
