External battery management
detected but not configured.
• Start QCG and configure a new
system with external energy
management (e.g., system with
lithium-ion battery).

A 20% recalibration of the bat-
tery state of charge has been
performed with a jump of more
than 10%.
• Check the battery.

Corrective measures
W 309 RlyProtect
1
Excessive current has been
applied to the transfer relay
of the device at L1
: Excessive
current has been applied to the
internal transfer relay of the
master.
• Reduce the total power of the
loads, e.g. by staggering their use
over time.
• Connect the loads with very high
power directly to the generator
whenever possible or connect the
utility grid. Ensure that the generator
is not overloaded.
• In off-grid systems, ensure that the
country data sets of the SMA
inverters are set to stand-alone grid
operation (see the installation
manuals of the SMA inverters).
W 310 RlyProtectSlv1
1
Excessive current has been
applied to the transfer relay
of the device at L2
: Excessive
current has been applied to the
internal transfer relay of slave 1.
W 311 RlyProtectSlv2
1
Excessive current has been
applied to the transfer relay
of the device at L3
: Excessive
current has been applied to the
internal transfer relay of slave 2.
F 314 ExtVtgLoss
2
External voltage failure
: The
voltage and/or frequency of the
generator or the utility grid are
outside of the configured range.
Corrective measures for a genera-
tor:
• Adjust the thresholds for generator
frequency and/or voltage on the
Sunny Island (see the Sunny Island
inverter installation manual).
Observe and analyze the measured
values
134.02 ExtVtg
and
134.04 ExtFrq
during operation.
• Adjust the generator voltage and/
or generator frequency.
Corrective measures in battery
backup systems:
• Contact the Service, if required (see
Section 16 "Contact", page 161).
