1Introduction

The STP 60 inverters are designed to act exclusively as grid-tie inverters for PV systems. The inverter converts direct voltage generated by a PV array to alternating current. The device must be connected to the utility grid and a sufficient number of PV modules in order to operate properly. The STP 60 inverters are not suitable for any other applications (such as operation with battery or wind turbine systems).

The STP 60 system consists of four main components:

• Sunny Tripower 60

• PV array junction box The PV array junction box makes it possible to combine

the needed number of PV strings for the STP 60 inverter. A PV array junction box is needed for each STP 60 inverter.

• SMA Inverter Manager The SMA Inverter Manager is required for the

operation of the Sunny Tripower 60. Up to 42 Sunny Tripower 60 inverters can be connected to one SMA Inverter Manager. The SMA Inverter Manager handles all communication of the inverters. It serves as central interface for data acquisition systems, upload to cloud services and power-plant control.

• Local commissioning and service tool (LCS tool) The LCS tool is required for commissioning and

servicing STP 60 inverters via the SMA Inverter Manager. The LCS tool acts as the primary user interface of the STP 60 system.

2.6 Grid Connection

These instructions for utility grid connection are for qualified personnel only. To reduce the risk of electric shock, do not perform any maintenance work other than that specified in the user manual unless you are qualified to do so.

For fuse and RCD information, refer to Section 5, page45. AC fuse rating must not exceed the ampacity of the conductors used.

INFORMATION

All electrical installations in the U.S. and Canada must be made in accordance with the local standards and National Electrical Code the Canadian Electrical Code

ANSI/NFPA70 or

CSA C22.1.

• Before connecting the inverter to the utility grid, contact your local grid operator. The electrical conn ectio n of th e inve rter mus t be ca rried out by qualified persons only.

• Ensure that no cables used for electrical connection are damaged.

IMI Detection

The inverter has built-in IMI/RCMU (Insulation Monitoring Interrupter / Residual Current Monitoring Unit) according to the UL 1741 for non-isolated EPS interactive PV inverters. It acts on continuous ground fault current and a sudden change in the ground fault current. This functionality is activated during normal operation.

Insulation Resistance Detection

The inverter has a built-in insulation resistance detection / ISO circuit, which is certified according to the UL 1741 for non-isolated EPS interactive PV inverters. The insulation resistance detector performs a measurement of the connected PV system resistance to ground before the inverter connects to the grid. If the resistance is below the gr id c ode set val ue, the inv erter wil l wa it a nd r e-m eas ure the resistance after a short while. When the resistance is above the grid code set value, the inverter performs a self-test and connects to the grid.

2.8 Ethernet Connections

For outdoor use, ensure that an appropriate cable is used. If the cable is very stiff, an intermediate terminal should be used in order to change from a stiff to a more flexible cable before entering the inverter. For some cables it might be sufficient to remove the hard outer mantle of the part of the cable inside the inverter enclosure. This is to protect the PCB-mounted RJ-45 Ethernet ports from excessive strain, which could lead to damage or connection issues.

Procedure:

1. Do not remove the RJ-45 connector on the Ethernet cable.

2. Run the cables through the base of the inverter via cable glands. See figure 2.22.

3. Cut slice in rubber grommet. Place the grommet in the gland to ensure proper seal.

4. Plug into the Ethernet connector.

2.9.1 External PV Array Junction Boxes

PV str ing s mu st b e co nne cte d to the DC i npu t vi a an ext ern al PV array junction box. The PV array junction box connects the PV strings of the PV array and protects the individual strings against overcurrent.

INFORMATION

The same number and type of modules must be connected to all PV strings connected to the PV array junction box. In addition, all connected modules must have the same orientation.

INFORMATION

Observe correct fuse rating. Consult module manufacturers' manuals for information on correct string fuse rating.

Use a suitable voltage detector that can measure up to 1,000 V DC. Verify the polarity and maximum voltage of the PV arrays by measuring the PV open-circuit voltage. The inverter is protected against reversed polarity and will not generate power until the polarity is correct.

The combined output from the DC combiner must be connected to the DC input of the STP 60 inverter.

PV array is floating, with both the (+) and (-) conductors connected to the inverters' PV inputs. Neither conductor is connected to ground.

The DC power can be disconnected with the inverter-integrated DC load-break switch.

Do NOT connect PV to ground!

SMA Solar Technology AG 3 Initial Setup and Start

Protection class of PV modules

The inverter must only be operated with PV modules of protection class II, compliant with IEC 61730, application class A.

Only connect PV modules to the inverter. Other energy sources are not allowed.

PV modules generate a voltage when exposed to light.

2.10 Closure

1. Close the cover of the inverter installation area. Fasten the three front screws. See Section 5.5, page50.

2. Turn on AC power.

3 Initial Setup and Start

3.1 User Interface

The user interface comprises:

• Local display, for all inverter variants. The local display shows status information of the inverter. It is not possible to configure or set up the STP 60 inverter via the display. The "#" in the display explains the operation modes.

• Local commissioning and service tool (LCS tool). The LCS tool enables configuration of one or multiple STP 60 inverters.

3.1.1 Operating Modes

The inverter has five operation modes, indicated by LEDs.

Status LEDs LEDs

Off grid Green

Red

Connecting Green

Red

On grid Green

Red

Internal inverter event Green

Red

Fail safe Green

Red

Off grid (standby) (LEDs off) #0-51 When no power has been delivered to the utility grid for

more than ten minutes, the inverter disconnects from the grid and shuts down. User and communication interfaces remain powered for communication purposes.

Connecting (green LED flashing) #52 to 53 The inverter starts up when the PV input voltage reaches the

minimum DC feed-in voltage. The inverter performs a series of internal self-tests, including measurement of the resistance between the PV arrays and ground. Meanwhile, it also monitors the grid parameters. When the grid parameters have been within the specifications for the required amount of time (depends on grid code), the inverter starts feeding into the utility grid.

On grid (green LED on) #60 The inverter is connected to the utility grid and feeds into the

utility grid. The inverter disconnects when:

• it detects abnormal grid conditions (dependent on grid code),

• an internal event occurs, or

• PV power is insufficient (no power is supplied to the grid for ten minutes).

The inverter then enters connecting mode or off-grid mode.

Internal inverter event (green LED flashing) #54 The inverter is waiting for an internal condition to be within

thresholds (for example when the temperature is too high) before it re-connects to the utility grid.

Fail safe (red LED flashing) #70

If the inv ert er d ete cts an e rror i n it s ci rcu its dur ing the sel f-test (in connecting mode) or during operation, the inverter goes into fail s afe mo de, disc onnec ting f rom t he gri d. The in verter will remain in "fail safe" mode until power has been absent for a minimum of ten minutes, or the inverter has been shut down completely (AC+PV).
