 Re-charge the battery or reduce the AC loads to continue operation.
-If the error immediately pops up when switching on the inverter (without load) on a full battery the cause is most likely a broken internal fuse.

 ==== Err 55, Err 56, Err 58 - Inverter self test failed ====
 The inverter performs diagnostic tests before it activates its output. In the case that one of these tests fails an error message is displayed and the inverter does not turn on.

 This error will not auto-reset. Check the installation and restart the unit using the power-switch.
+==== Err 59 - ACIN1 relay test fault ====
+Automatic checking of the disconnect means failure.
+This usually indicates a broken relay (sticky contact) in the AC input stage.

 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.
 The inverters remain operational, they won't connect to the grid. Once the issue is resolved the units will connect.
