F 201 VBATMAX 2 Battery voltage at 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. When doing so, bear in mind
the technical data for the battery at the
DC connection (see the Sunny Island
inverter installation manual).
•
Ensure that the DC sources are correctly
connected and configured.
W 202 VBATMAXSL1 1 Battery voltage at 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.
