10 Cleaning and Maintenance
10.1 Cleaning and Checking the Sunny Island Inverter Enclosure
• If the enclosure is heavily soiled, use a soft brush to remove the soiling.
• If the enclosure is dusty, remove the dust with a dry soft cloth. Do not use any solvents, abrasives or corrosive liquids.
10.2 Cleaning the Sunny Remote Control
• Clean the Sunny Remote Control with a dry soft cloth. Do not use any solvents, abrasives or corrosive liquids.
10.3 Performing a Manual Equalization Charge in the Off-Grid System
After extended periods without charging (e.g., systems operated seasonally), perform a manual equalization charge at
the end or start of the season.
Requirement:
☐ The Sunny Remote Control must be in standard mode or user mode.
Procedure
1. Select the display page Battery on the Sunny Remote Control and press the button (see Section 5.3.1 "Displaying
Parameters and Operating and Setting the System", page 27).
2. Select the parameter Equalize and set to Start.
10.4 Checking the Function
• For the first six months after installation of new systems, check every week whether error messages have been
logged. This will reveal any hidden errors in the installation or configuration:
• Switch to installer mode on the Sunny Remote Control (see Section 5.4.1, page 29).
• Select the menu 420# Error history and check whether any error messages have been logged.
• If error messages have been logged, eliminate the cause (see Section 9 "Troubleshooting", page 41).
• Check every six months whether error messages have been logged:
• Switch to installer mode on the Sunny Remote Control (see Section 5.4.1, page 29).
• Select the menu 420# Error history and check whether any error messages have been logged.
• If error messages have been logged, eliminate the cause (see Section 9.4 "Logged Warning Messages and Error
Messages", page 46).
10.5 Checking the Connections
2. Ensure that the cables on the DC+ and DC‒ connections are securely fastened (torque: 12 Nm).
3. Ensure that the connections are free of corrosion.
4. Ensure that the cables in the AC1 and AC2 connections are securely fastened.
5. Close the Sunny Island (see the Sunny Island inverter installation manual).
6. Switch on all load-break switches and circuit breakers.

Danger to life from electric shock due to live voltage
High voltages are present inside the Sunny Island. When the enclosure lid is removed, live components can be
touched which can result in death or serious injury due to electric shock.
• Disconnect the Sunny Island from voltage sources (see Section 8, page 40).
