Overload
Battery voltage is too low.
Corrective measures:
6610
Overload
Battery voltage is temporarily too high.
Corrective measures:
6612
Overload
Excessive current has been applied to the internal transfer relay of the Sunny Island at line
conductor Lxx.
Corrective measures:
6613
Overload
The power of the loads is too high for the Sunny Island at line conductor Lxx.
Corrective measures:

• Charging the battery:
– Charge the lead-acid battery in emergency charge mode.
– Charge lead-acid batteries with external battery charger (see documentation of the
battery manufacturer).
• Ensure that DC loads are shed via a load-shedding contactor when the battery state of
charge is low.
• 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.
• 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 mode.
• Ensure that the inverter is functional. Clean the fans and restart the inverter.
• Ensure that there are no short circuits in the system and that the power of the loads is not
greater than the power of the Sunny Island inverter.
• Use a star delta electronic circuit to start three-phase loads with a high start-up electricity
demand (e.g. motors).
• Connect the loads with very high power directly to the generator whenever possible.
Ensure that the generator is not overloaded.
