Level Cause
3 Overtemperature fault in
battery: The battery tempera-
ture is too high.
3 Measuring range of battery
voltage exceeded in device
at L2: Battery voltage is higher
than the target charge voltage.
1 The battery voltage is too high
and has not been generated by
the device.
1 Battery overvoltage: Battery
voltage is temporarily too high.
1 Undertemperature fault in
battery: The battery tempera-
ture is too low.
1 Overtemperature fault in
battery: The battery tempera-
ture is too high.
3
Battery undervoltage: Battery
voltage is too low.
1 Current battery capacity (SOH)
is below 70%.

Corrective measures
• Wait for the battery to cool down.
Useful hint: Protect the battery
against temperatures above 25°C.
This helps prevent premature aging
of the battery.
• Check whether the electrical
resistance of the battery
temperature sensor is approx.
2000 Ω at 20°C to 25°C. If the
resistance deviates strongly from
this value, replace the sensor.
• Ensure that all DC sources are
correctly configured.
• Ensure that all SMA inverters are
configured to the country data set
for stand-alone grid operation.
• Ensure that the battery room is
sufficiently warm.
• Wait for the battery to cool down.
Useful hint: Protect the battery
against temperatures above 25°C.
This helps prevent premature aging
of the battery.
• Charge the battery in emergency
charge operation or using an
external battery charger (see
Section 10.7 "Charging the Battery
After Automatic Shutdown in Off-
Grid Systems (Emergency Charge
Mode)", page 89).
• Ensure that DC loads are shed via a
load-shedding contactor when the
battery state of charge is low.
• Verify the plausibility of the error
message and replace the battery if
necessary.
