7.24.4 Testing the Generator
If a generator is present, you must carry out the following steps:
Requirements:
☐ The miniature circuit-breakers for the AC sources must be switched off in the AC sub-distribution.
☐ The miniature circuit-breakers for DC sources must be switched off in the DC sub-distribution.
☐ The off-grid inverter must be in operation (see Section 7.24.2"Starting the Off-Grid
System",page116).
1. Connect the miniature circuit-breakers in the sub-distribution for external energy sources.
2. Connect the miniature circuit-breakers of the AC loads in the AC sub-distribution.
3. Connect the loads.
☑ The generator starts or the generator request is shown.
✖ Does the generator not start?
Generator management does not request the generator.
• Manually start the generator with the Sunny Remote Control (see the operating manual
of the off-grid inverter).
The generator or signal generator is not being activated.
• Rectify any faults in the wiring.
The generator is not operational.
• Identify possible causes using the manufacturer's manual and rectify these.
4. Switch to installer mode (see Section 7.5).
5. Select the 133.02 GnStt parameter and wait until the Run parameter is shown. In this way,
you will know that the off-grid inverter has connected the stand-alone grid to the generator.
✖ Is the grid LED glowing red?
The off-grid inverter does not switch the stand-alone grid to the generator due to an error
message.
• Select the 410# Error active menu and rectify the cause of the displayed warning or
error.
6. For single systems and single-cluster systems, check whether the connected active power of the
loads corresponds to the value of the 111.05 TotLodPwr parameter.
If the power shown is too high, rectify the defective load or fault in the wiring.
7. For multicluster systems, check whether the value of the 111.06 TotMccLodPwr parameter
corresponds to the connected active power of the loads.
If the power shown is too high, rectify the defective load or fault in the wiring.
8. Stop the generator (see the operating manual for the off-grid inverter).
