Operational status (display)

The inverter's operational statuses are shown on the inverter's display:

INFO

The user interface/menu items in the inverter depend on the software installed in the inverter and may differ from the description here.

1	Display area, information and inverter status displayed

The following table explains the operational notifications that can appear on the display:

Symbol	Display	Explanation
---	Off	Input voltage on the DC side (photovoltaic modules) is too low or inverter switched off.
	Bell symbol	An event is present. Remedial measures can be found in the chapter Event codes. The event can be queried in the inverter menu by going to Service > Event list or can be viewed using the Down arrow key.
	Software update symbol	There is a software update available for the inverter. The software update process can be started in the inverter menu under Service > Updates or via the inverter.
	Globe symbol	Shows a successful connection to the solar portal.
	Wifi icon	Displays the Wifi connection status.

Display	Explanation
IP address	Inverter IP address
Insulation measurement	Device performs an internal check
Grid check	Device performs an internal check
Starting	Internal control measurements according to VDE 0126
Starting, including check of DC generators	Device performs an internal check
Feed in	Measurement successful, MPP control active (MPP = maximum power point)
Feed-in ext. regulated	The feed-in is limited due to a fault (e.g. PV energy is restricted, Active power control, too high temperature, fault)
Shutdown by ext. signal	The feed-in is shut down as a result of an external signal from the energy supply company.
Event xxxx, yyyy	An event is present. Up to two active events can be displayed. Remedial measures can be found in the chapter Event codes.
Waiting time ...	The device is not feeding into the public grid due to an event. Grid synchronisation: The inverter synchronizes itself with the public grid and feeds in. Grid check: A grid check is carried out. Grid error: There is an error in the public grid. As soon as this is rectified, the inverter feeds in again. Overheating: The inverter’s temperature is too high. As soon as this has fallen, the inverter feeds in again.
DC voltage too low	Electronics are ready for operation, DC voltage is still too low for feed-in.
Impermissible DC voltage	DC voltage still too high.
Ext. battery control active (only with battery connected)	The battery is controlled by an external management system. Ch. 8.1
Deep discharge protection (only with battery connected)	The battery which is connected to the inverter is charged from the public grid using an equalisation charge.
Equalisation charge (only with battery connected)	The battery which is connected to the inverter is charged from the public grid using an equalisation charge. It can only be activated with installer access via the service menu.
Service charging (only with battery connected)	The battery which is connected to the inverter is charged from the public grid using an equalisation charge. It must be activated via the service menu. It can only be activated with installer access via the service menu.
Battery sleep mode (only with battery connected)	If the battery charging status falls below the min. SoC (e.g. 5% for BYD batteries), the battery sleep mode status is displayed and the battery is disconnected from the system. Sleep mode is exited as soon as the battery can be charged with excess power. If the SoC of the battery falls below the minimum allowed SoC, the battery receives a trickle charge of x% of the total battery capacity from the grid to protect the battery. Trickle charge: 5% trickle charge the first time the SoC falls below the permitted value. 10% trickle charge the second time the SoC falls below the permitted value. 15% trickle charge the third time the SoC falls below the permitted value. Once sleep mode has been exited, the next trickle charge starts again with +5 %.
