6.4.2 Connecting the AC Output
To connect up the AC output, follow these steps:
Step Instruction
1Check the grid voltage!
For Germany, the following applies: If the grid voltage is constantly higher
than 253 V, the Sunny Mini Central will not be fully operational. In this case,
contact the local grid operator for assistance. The inverter can temporarily
feed power into the grid with a maximum output voltage of 260 V. However,
the 10-minute average must not exceed 253 V.
2Isolate the grid connection (switch the line
circuit breaker to its "off" position), make
sure it cannot be switched back on, and test
to make sure no voltage is present.
3Make sure that the PV generator is not connected to the inverter!
4Remove the screws that secure the housing
cover of the Sunny Mini Central. Put the
screws and the washers to one side so that
they do not get lost. Pull the cover forward
to remove it.
