9.4 Checking the Function
Requirement:
☐ The Sunny Remote Control must be connected to the off-grid inverter/master.
• For the first six months after installation of new off-grid systems, check every week whether error
messages have been registered. TThis will reveal any hidden errors in the installation or
configuration:
• Switch to installer mode (see Section 4.4.1).
• Select the 420# Error history menu and check whether error messages have been
registered.
• If error messages have been registered, rectify the cause
(see Section 10"Troubleshooting",page54).
• Check every six months whether error messages have been registered:
• Switch to installer mode (see Section 4.4.1).
• Select the 420# Error history menu and check whether error messages have been
registered.
• If error messages have been registered, rectify the cause (see the technical description of the
off-grid inverter for the causes of errors and disturbances).
9.5 Checking the Connections
1. Disconnect the off-grid inverter from voltage sources (see Section 8).
2. Ensure that the cables on the DC+ and DC- terminals are securely fastened
(torque: 4 Nm ... 5.7 Nm).
3. Ensure that the terminals are free of corrosion.
4. Ensure that the cables in the AC1 and AC2 terminals are securely fastened.
5. Close the inverter (see the off-grid inverter installation manual).
6. Switch on all switch-disconnectors and miniature circuit-breakers.
