Possible cause
High temperature protection of the
house battery: The inverter charger
combination switches to reduced
charging current when the tempera-
ture of the battery exceeds the cutoff
value (>52 °C).
Only LiFePO4 batteries: Low tempera-
ture protection of the house battery.
The inverter charger combination
switches to reduced charging current
(up to 10 % of the maximum charging
current) when the temperature of the
battery drops below the cutoff value
(<0 °C).
The device is in constant voltage phase. No action required (see chapter "Battery
Mains input current is limited.
Output power exceeds permanently
the continuous output power.
The battery is defective.
The remote control is connected incor-
rectly.
Night mode is activated.

Suggested remedy
➤ Check that the air inlets and outlets are not
covered or obstructed.
➤ Allow the battery to cool down.
The inverter charger combination returns auto-
matically to full charging current when the tem-
perature drops to the restart value (<50 °C).
➤ Ensure ambient temperatures >0 °C.

➤ Set the switch for AC input current limita-
tion to maximum current (see chapter "Lim-
iting the mains input current" on page 26).
➤ Ensure that the total nominal power of the
AC output load is lower than the continu-
ous output power of the inverter.
➤ Replace the battery.
➤ Check the connections.
➤ Switch off the night mode (see chapter
"Setting the night mode" on page 26).
