SMA Solar Technology AG Commissioning
Installation Guide SC125_560HE-IEN083220 73
6 Commissioning
Before commissioning, all work performed on the device should be thoroughly checked. In particular,
the voltages on the DC and AC sides should be checked for conformance to the limits allowed on the
inverter and polarity.
6.1 Requirements for commissioning
Before commissioning, the following requirements have to be filled for correct commissioning of the
Sunny Central in accordance with the regulations.
The PV generator must be constructed and tested in accordance with VDE 0100 part 610 BGV A2
"Electrical Systems and Appliances". The grounding resistance is decisive for the safety of the
complete system and must therefore be determined before initial commissioning.
6.2 Cabling Checks
When performing the cabling checks, the connections made between the switch cabinet units are first
checked for correctness and proper installation.
In particular the following points must be checked:
• Correct order and tight mounting of the plugs of the transfer terminal strip
• Tight fixation and correct phase series of the transformer or sine filter connections
• Correct connection of the data and control lines at the power unit
• Correct connection of the data line for insulation monitoring
• Mounting location of the internal temperature sensor
• Internal power cabling for the team concept
• Are the PE rails of the cabinet components connected with each other?
6.2.1 Cabling Check AC Grid Connection
• The connection made to the feed-in cables is 3-phase.
• A right-hand rotary field must lie at L1, L2, L3.
• Measuring and recording the amount of the AC voltage.
• Make sure that the terminals are securely positioned.
Any warranty or guarantee claims are only valid when the commissioning gas been carried
out by SMA or when the "Commissioning report for Sunny Central systems" provided by
SMA is complete, signed and accessible to SMA.
Circuit breaker and motor overload switch
In the delivered state, all circuit beakers and motor overload switches in the Sunny Central
are switched off.
