9.1 Sunny Island Inverter Behavior Under Fault Conditions

Display of errors, warnings, and events

Pending warnings and errors are shown automatically on the display of the Sunny Remote Control until the cause of the warning or error is no longer logged by the Sunny Island or has been acknowledged. Events are logged by the Sunny Island. The following menus log warnings, errors and events:

• 410# Error active - display of currently pending warnings and errors

• 420# Error history - warning and error history

• 430# Event history - events history

• In systems for increased self-consumption and battery backup systems: 440# Error Grid - history of the last five utility

grid errors

Structure of display numbers

Each error and each event has a unique three-digit display number that is determined based on the parameter or measurement value assignment. Events and errors use the same number range:

• 1xx - Sunny Island

• 2xx - Battery

• 3xx - Generator or utility grid

• 4xx - Generator

• 5xx - Utility grid

• 6xx - Relay

• 7xx - System

• 8xx - External devices and components

• 9xx - General

Meaning of abbreviations F indicates an error, W a warning, and E an event. In the event of an error, the display shows whether the error has come or gone using ! for "Set" and C for "Clear".

Error Levels

The Sunny Island distinguishes between five different levels of errors, each requiring different user interaction.

must be replaced.

Handling of pending errors upon activation

During the activation procedure, all pending errors are acknowledged without the error being logged in the list 420# Error history. Errors which are still pending are entered again after activation. Errors which were detected by the Sunny Island before activation and are no longer detected after activation are shown in the list 420# Error history.

Autostart

The autostart function allows automatic restarts in the event of malfunctions. If the autostart function fails in the event of a malfunction, the Sunny Island attempts to carry out the next autostart immediately. The number of autostarts is restricted. If the Sunny Island is in operation without malfunctions for ten minutes, it resets the autostart counter.

When the maximum number of autostarts has been reached, the Sunny Island reacts as follows:

• The Sunny Island waits ten minutes.

• The autostart counter is reset.

• The Sunny Island attempts to perform an autostart.

• When the maximum number of autostarts has been reached, the Sunny Island waits again for ten minutes.

9.2 Acknowledging Errors

If a malfunction or failure occurs, the Sunny Island switches to standby mode. Once you have eliminated the cause of the error, you can enable a restart of the Sunny Island inverter by acknowledging the error.

Procedure:

1. Eliminate the cause.

2. Press the button on the Sunny Remote Control. This acknowledges the error.

3. Start the system (see Section4.2, page18).

9.5 Frequently Asked Questions (FAQ)

9.5.1 Questions Regarding the Sunny Island

The Sunny Island does not switch off even though you have opened the load-break switch of the BatFuse?

The Sunny Island may still be supplied from the AC side.

• Switch off all AC sources and disconnect them from the Sunny Island.

The Sunny Island does not switch to energy saving mode?

Another function might have a higher priority than energy saving mode, e.g., equalization charge or full charge.

After automatic disconnection in battery protection mode, the Sunny Island can no longer be started?

• Only charge the battery when the Sunny Island cannot be switched on (see Section9.6 "Charging the Battery After Automatic Shutdown in Off-Grid Systems", page72).

• Switch off all loads.

• If there is a generator in the system, start the generator manually. When doing so, observe the warm-up time of the generator. Five minutes without charge current can result in disconnection of the Sunny Island inverter.

• If sufficient power is available from the generator or the AC sources in the stand-alone grid, e.g., sufficient solar irradiation for PV inverters, switch the Sunny Island on. AC sources in the stand-alone grid can only start feeding in electric current once the Sunny Island has been started and is in operation.

9.5.2 Questions Regarding the Sunny Remote Control

The display of the Sunny Remote Control is dark and nothing is displayed?

The Sunny Island might not be switched on.

• Switch the Sunny Island on (see Section4.1, page18).

✖ The Sunny Island does not switch on?

• Ensure that the fuse in the BatFuse is not defective.

The Sunny Remote Control might not be connected to the Sunny Island.

• Ensure that the Sunny Remote Control is connected to the Sunny Island.

The RJ45 data cable may be damaged.

• Replace the RJ45 data cable between the Sunny Remote Control and the Sunny Island.

"MMC/SD operation failed !" is shown in the display?

An action with the SD memory card has failed.

• Use a computer to ensure that the SD memory card is free of errors.

• Ensure that the data cable between the Sunny Remote Control and the Sunny Island is undamaged and that the plugs are firmly inserted into the pin connectors.

The display shows "WRONG FILE SYSTEM"?

The SD memory card is not formatted with the FAT-16 or FAT-32 file system.

9.5.3 Questions Regarding the Battery

A battery cell is defective?

• Remove the defective battery cell from the battery system. This reduces the rated voltage of the battery by the voltage of the battery cell.

• In the QCG, set the current rated voltage of the battery under New Battery (see Section10.8 "Replacing the Battery", page78).

The state of charge of the battery is not 100 percent after completion of a full charge?

The power requirements of the loads might have been so high before completion of the full charge that the battery could not be charged 100 percent.

•If necessary, select the parameter 222.03 AptTmFul and set to a longer time period.

The battery discharges even though the generator is running?

The Sunny Island may not have connected to the generator.

• Eliminate the cause (see Section9.5.4 "Questions Regarding the Generator", page70).

The power of the loads might exceed the power of the generator.

What do you need to do after replacing a battery current sensor?

• Calibrate the battery current sensor (see the Commissioning section in the Sunny Island inverter installation manual).

9.5.4 Questions Regarding the Generator

The Sunny Island does not connect to the running generator?

A high output power of the Sunny Island inverter when the battery state of charge is low may lead to the Sunny Island not being able to raise the AC voltage in the stand-alone grid to the AC voltage of the generator. The Sunny Island cancels the synchronization.

• To charge the battery, reduce the power of the loads.

The generator voltage might not be within the thresholds for voltage and frequency.

• Check whether the symbol " " is displayed permanently in standard mode. If the " " symbol is not displayed, ensure that the fuse is not defective or the circuit breaker is activated. If the " " symbol is not displayed permanently, the generator voltage is sporadically outside the thresholds.

• Set the thresholds for voltage and frequency of the generator voltage (see the Sunny Island inverter installation manual).

If the " " symbol is displayed permanently, the Sunny Island is in the warm-up period or is blocked for connection. Tip: Check whether the Sunny Remote Control displays the " " warning symbol in standard mode.

70 SI30M-44M-60H-80H-BE-en-30 Operating Manual

SMA Solar Technology AG 9 Troubleshooting

The Sunny Island only connects to the generator for a short time?

The generator may be overloaded.

• Select the parameter 234.03 GnCurNom and set it to 75% of the rated current of the generator.

• If possible, reduce the power of the loads.

The maximum permissible generator voltage may be set too low.

• Select the parameter 234.02 GnVtgMax and set to the maximum generator voltage.

The minimum frequency for the generator voltage may be set too high.

• Select the parameter 234.05 GnFrqMin and set to the minimum frequency of the generator voltage.

The permitted time 234.14 GnRvTm for reverse power might have been exceeded.

• Check whether warning W401 is registered in the menu 420# Error history. Tip: If a warning was registered, the warning symbol " " is shown in the standard mode of the Sunny Remote Control.

• Select the 540.02 GnAck parameter and set to Ackn. This acknowledges the generator error.

The Sunny Island does not reconnect to the generator after a disconnection from the generator due to noncompliance with the thresholds for voltage and frequency?

The Sunny Island is switched with a hysteresis, i.e., the thresholds for connection do not correspond to the thresholds for disconnection.

• To unload the generator, disconnect unnecessary loads.

• Wait until the voltage and frequency have reached the nominal values.

9.5.5 Questions Regarding Multicluster Systems

Extension clusters remain in standby mode even though the main cluster is in inverter mode?

The data cable between the masters of the individual clusters might not be connected. The master of the main cluster cannot forward the "Start" command to the masters of the extension clusters.

The multicluster system is not supplying full power?

An extension cluster or individual Sunny Island inverters of an extension cluster might have failed.

High levels of energy are transferred between the clusters in the multicluster system?

The state of charge of the batteries might differ temporarily. The off-grid system equalizes different states of charge automatically.

The nominal frequencies and nominal voltages may be defined differently.

• Set the frequencies and voltages in the 210# Inverter Settings menu to the same values for all masters.

The battery capacities might differ significantly.

• Distribute the battery capacities to the clusters as evenly as possible.

Individual battery cells of a battery might have failed.

• Disconnect defective battery cells and set the new rated voltage and capacity (see Section10.8 "Replacing the Battery", page78).
