9 Troubleshooting SMA Solar Technology AG
48 SI60H-80H-BE-en-20 Operating Manual
9.4.2 Battery Category (2xx)
F 169 Overload30min 3 The 30 minute overload capacity
of the master has been exceeded.
• Reduce the power of the loads.
W 170 Overload30minSlv1 1 The 30 minute overload capacity
of slave 1 has been exceeded.
W 171 Overload30minSlv2 1 The 30 minute overload capacity
of slave 2 has been exceeded.
F 172 Overload 3 The overload capacity of the
master has been exceeded.
• Reduce the power of the loads.
W 173 OverloadSlv1 1 The overload capacity of slave 1
has been exceeded.
W 174 OverloadSlv2 1 The overload capacity of slave 2

F 201 VBATMAX 2 Battery voltage on the master is
above the permissible
measurement range.
• Check whether the value of the
parameter 120.02 BatVtg is above
65.0 V. If the value is above 65.0 V,
check the settings of the DC sources and
ensure that the battery capacity is
sufficient. Observe the technical data of
the battery at the DC terminal (see the
Sunny Island installation manual).
•
Ensure that the DC sources are correctly
connected and configured.
W 202 VBATMAXSL1 1 Battery voltage on slave 1 is
above the permissible
measurement range.
W 203 VBATMAXSL2 1 Battery voltage at slave 2 is
above the permissible
measurement range.
F 206 BatTmpHi 3 The battery temperature is too
high.
• Wait for the battery to cool down. Tip:
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.
2,000 Ω at 20°C to 25°C. If the
resistance deviates strongly from this
value, replace the sensor.
F 208 BatVtgHi 3 The battery voltage is greater
than the target charge voltage.
•
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.
