2.2 Appropriate use
The SolarMax TS series inverters are designed exclusively to convert the direct current generated by PV modules into alternating current which conforms to the parameters of the public grid. Any other use is contrary to the purpose for which the inverters were designed.
The inverter may only be connected to a suitable medium-voltage transformer. It is not permitted to connect the unit directly to a medium-voltage switch circuit or to the power grid.
SolarMax Produktions GmbH accepts no liability for damages resulting from using inverters for purposes other than this. Any modifications to the inverter performed by the system operator or the electrician without a review and approval by SolarMax Produktions GmbH are prohibited.

3 Description of the station components
This chapter describes the station components.
3.1 SolarMax TS-SV inverter
The main component of a station is the SolarMax TS-SV central inverter. It converts the PV generator’s direct current into alternating current which conforms to public grid parameters. The output of a station depends on the number of installed TS-SV inverters. One to four TS-SV inverters together with an MCU make up an inverter system that is connected to a medium-voltage transformer.
The TS-SV inverter consists of three independent power units. Each power unit has its own MPP tracker, DC-end overvoltage conductors, power switches on the DC and AC end (Q1 to Q6), a contactor at the AC end (K1 to K3) and EMV filters. All power switches are accessible from outside when the inverter casing is closed.
The control units of the power units have two digital signal processors (DSP) which assume all the monitoring, controlling and regulating tasks. All the safety-relevant values are continuously monitored and compared by both processors. The result is greater oper-ating safety and reliability. The DSP’s high performance enables precise and rapid identi-fication of the maximum power points (MPP) of the PV generator and, combined with the low-loss power unit, delivers maximum yields. The completely digital regulation ensures outstanding quality of the current fed into the grid which means extremely negligible grid reactions.
The inverters of the TS-SV series are capable of delivering reactive power if necessary to actively support the mains during short blackouts, to reduce output in response to rising mains frequency and to receive and implement remote control commands (power output reduction, etc.).
The inverter comes from the factory configured for multi-MPPT operation. All the DC inputs of the installed inverters must be connected in parallel and fitted with fuses for the single MPPT operating mode. A short description of these operating modes can be found in section 3.3 “Configuration variants of the station”.
The inverter is not fitted with potential separation. This is provided by the medium-voltage transformer.

3.2 TS-SV master control unit (MCU)
The TS-SV master control unit (MCU) is the control and operating unit for as many as four TS-SV inverters. The interfaces and contacts of the MCU enable innumerable com-munications and monitoring variants, see 5.4.6 “Interfaces and contacts of the MCU”.
The MCU is connected to the TS-SV inverter via a modular bus interface. The MCU is powered both from the AC end (from the autonomous power supply transformer) as well as from the DC end. This enables the MCU to operate around the clock. The MCU has a switch that you can use to configure the single or multi MPPT operating mode see 5.5 “Configuring the MCU”.
The MCU has a mounting rail that enables the installation of the MaxWeb xp web-based data logger and the potential equalization set (PAS).

3.4 Additional station components
The following station components are not supplied by SolarMax Produktions GmbH:
■■ DC fuse box■■ Autonomous power supply transformer (transformer for the station‘s own power
supply)■■ Medium voltage transformer and 400 V low-voltage installation■■ Medium voltage switchgear■■ AC fuses between each inverter and the medium-voltage transformer
The design of these components is in the hands of the station outfitter. The details con-tained in the following sections are only standard values and typical characteristics.
3.4.1 DC fuse unit
The DC fuse unit is only needed if the intention is to operate the station in single MPPT operating mode. The station outfitter is responsible for constructing the DC fuse unit. When you dimension the DC fuse unit keep in mind the connection conditions for the single MPPT operating mode, see 5.3.2 “Connect inverter to the PV plant”.
3.4.2 Autonomous power supply transformer
The autonomous power supply transformer powers the MCU and other, project dependent consumers (lighting, MaxWeb xp, fans, etc.) inside a station. The use of an autonomous power supply transformer is necessary if no local 230 V / 400 V mains are available. The selection and dimensioning of the transformer is in the hands of the station outfitter.
Typical characteristics
The actual size of the autonomous power supply transformer (if necessary) depends on the number and type of the additional consumers inside the station.

3.4.3 Medium-voltage transformer
The medium-voltage transformer is the link between the local 280 V network within a sta-tion and the medium-voltage network. The inverter may only be connected to the power grid via a medium-voltage transformer. The medium-voltage transformer provides the potential separation between the PV power plant and the medium-voltage switch system or the power grid. The inverter does not have its own potential separation. The medium-voltage transformer is not included in the scope of supply.
Determining the size
The dimensioning of the medium-voltage transformer depends on the number of TS-SV inverters used. Dimension the medium-voltage transformer in such a way that its no-load losses remain as low as possible. The following reference values are applicable to a maximum ambient temperature of 40 °C.

4 Installation4.1 Transport & storage of the inverter
DANGER
■■ The inverter is a heavy device which, if not handled properly, can tip over during transport and cause serious personal injuries.
■■ The inverter must be transported upright.
4.1.1 Means of transport
Forklift trucks
The inverter has openings in its base to allow it to be transported by a forklift truck. Secure the devices against falling.
Crane
At the upper corner struts the inverters have four M16 threaded cylinders (weld nuts). You can screw M16 eye bolts into these cylinders. These allow the inverter to be lifted by a crane or forklift truck.
DANGER
■■ If you use a forklift or some other lifting equipment take extreme caution. Make sure the lifting equipment has adequate lifting capacity.
■■ Secure the inverter against falling while it is being moved by a forklift truck.■■ Whenever this is done always make sure that the inverter’s weight is correctly
distributed on the lifting equipment (ensure that centres of gravity are properly distributed).
■■ Ropes or strips must have an angle of > 60° to the inverter top.
■■ Necessary minimum lifting capacity of the transport vehicle or lifting equipment: 950 kg (weight of the inverter).
20
4.1.2 Storage conditions
Store the inverter in a dry, enclosed space.
CAUTION
Possible damage to the device! Never store the inverter outdoors. Not even for a short time.
4.2 Site selection and operating conditions of the inverter4.2.1 Specifications and instructions for site selection
Choosing a suitable location for the inverter is decisive for its operating safety as well as its expected service life and efficiency. An ideal location is indoors or in a container with the following characteristics:
■■ The site must be dry to prevent any condensation from collecting in the inverter: no puddles, no damp masonry walls, no openings where snow or rain can enter.
■■ The ambient air of the inverter must be free from dust, salt, and ammonium vapours. If required (e.g. for installations near the sea or in desert areas), the ambient air of the inverter must be filtered (e.g. with an air conditioning unit or a filter).
■■ Do not install the inverter in rooms or work areas which contain or are made of com-bustible materials. Follow the local fire safety regulations.
DANGER!
Fatal electric shock hazard! – The inverter must be installed in an enclosed electrical plant room so that unauthorized persons have no access.
CAUTION
Fire hazard! - Suitable for mounting on concrete or other non-combustible surface only!
■■ Because the inverter is a source of noise, do not install it near residential spaces.■■ Make sure that the floor of the installation site is level and its bearing capacity is
adequate. ■■ The inverter must be installed on the entire contact face of the 6 bases.
21
en
■■ To ensure that the inverter is accessible for possible repair work the front side must be at least 1 m away from the nearest object (wall, other inverters, etc.). Do not install the inverter on a raised surface, platforms or consoles.
■■ Where the inverter and the medium-voltage transformer are installed in separate rooms, a warning note must be attached to both units: „Before carrying out any work to the AC connection between the inverter and the medium-voltage transformer, the electricity connection to the supply lines to the PV generator and the medium-voltage network must be switched off“.
4.2.2 Operating conditions at the site
■■ The ambient conditions are specified in the technical data, see section 7.■■ The installation location must meet the requirements contained in the standard for
electromagnetic immunity for industrial environments (EN 61000-6-2) and for emis-sions in industrial environments (EN 61000-6-4).
NOTE
■■ Please remember that the inverter and existing accessories give off heat during operation which can contribute to a serious heating up of the ambient air if the plant rooms are small or poorly ventilated.
■■ Our basic rule is always to recommend that the ambient temperature be kept under 30 °C.
■■ The ventilation at the site must provide an air change rate of 5000 m3 per hour and inverter. The air must flow through the inverter from bottom to top.
■■ Conditions in the plant room which could lead to even a short period of excessive ambient air temperature (TAmbient > 50 °C) make the installation of an additional ventilation system an absolute necessity.
22
4.2.3 Cooling system of the inverter
The inverter’s heat sinks are actively cooled by internal fans. The cool, fresh air enters the inverter from below, is drawn in by the fans and is blown upwards through the ventilation screens out of the inverter.
For safety reasons the heat sink temperature is limited to 85 °C. When ambient tem-perature is over 45 °C the heat sink temperature can reach 80 °C. If this happens, the maximum feed output is temporarily reduced and a corresponding status message appears on the inverter’s display screen. But if the temperature still runs as high as 85 °C the inverter is shut down to prevent a thermal overload.
NOTE
Optimal cooling is decisive for maximum inverter output yield. Install inverters only at a site corresponding to the description in 4.2.2 “Site selection and operating conditions”.
4.3 Recommendations for station construction
The construction and setup of the inverters in a station must meet the requirements of the IEC 62271 202 industrial standard.
The TS-SV inverters are generally built into a concrete station. The conception of the station depends on the country-specific standards and regulations for the construction of rooms containing electrical facilities and is the responsibility of the station outfitter.

4.3.1 Heating
The inverters are tested to operate at temperatures to -20 °C. Remember to check the minimum operating temperatures of the other components and, if necessary, to install a heating unit.
4.3.2 Excavating the construction site
The construction site must be excavated following the instructions of the station outfitter. Stations fitted with a basement ventilation system must be effectively protected against the intrusion of rain, snow and water through the lateral cooling shafts. There must be drainage channels and pipes in place and the subsurface soil must be permeable.
24
4.4 Lightning protection
The requirements for appropriate lightning protection for a PV power plant depend on many different factors (plant size, how the cables are run, the modules used, the sur-roundings, etc.).
A project-specific protection concept must be developed by a qualified person.
4.5 Montage4.5.1 Inverters
The inverters can be fastened to the floor with M12 screws. Use the hole pattern shown in 3.1.2 “External operating elements and dimensions”. In addition to anchorage to the ground the inverters can be anchored to the wall with a bracket above to the M16 threaded cylinders.
4.5.2 MCU
The MCU is usually mounted on the wall in the station. The hole pattern is shown in 3.2.1 “Exterior view and dimensions”.

5 Electrical connection5.1 Guidelines for electrical installation
DANGER
■■ Only qualified electricians may install and start-up the TS-SV inverter and the MCU.
■■ The local regulations and guidelines for the installation of electrical devices must be followed.
■■ All the feed lines to the inverter and the MCU must be appropriate for the expected voltages, currents and ambient conditions (temperature, UV load, etc.).
■■ Make sure that all lines are laid tension-free.
5.2 Earthing of the station components
As a principle, all metal parts which are not protected against being touched must be earthed.
DANGER
A correct earthing is vital for the operation and safety of the devices (for example, by an earthing strap buried in the ground).
The station components must be earthed as follows:
■■ Each inverter with two 95 mm2 wires connected to M10 threaded bolts. The position of the MS threaded bolts: see 5.3.1 “Interior view of the inverter”.
■■ The MCU with one 10 mm2 wire (also important for perfect communication between the MCU and inverters). The position of the terminals: see 5.4.1 “Interior view of the MCU”. The MCU must be grounded independently of the inverters.
■■ Each of the DC fuse boxes with one 95 mm2 wire per box.■■ The star point of the 400 V coil of the autonomous power supply transformer.■■ The AC-side overvoltage protection of the inverter is earthed.
DANGER
Never ground the possibly existing low-voltage star point at the medium-voltage transformer!
26
5.3 Connecting the inverter5.3.1 Interior view of the inverter
Open the inverter by loosening the four or three captive M5 screws of the left and right front cover.
DANGER
Make sure that all the DC and AC feed lines to the inverter are dead before you start the installation work.

5.3.2 Connecting the inverters to the PV plant
General connection conditions
■■ Per power unit as many as three DC feed lines (strings) can be connect in parallel.■■ Maximum DC input current per power inverter: 720 A■■ Maximum DC input voltage per inverter: 900 V■■ Maximum DC input current per power unit: 240 A■■ If the feed lines are long we recommend you use larger line cross sections to keep
down transmission losses. ■■ Maximum admissible over-dimensioning of the PV generator output power: 50 %.
NOTE
The DC inputs of the inverter are overvoltage protective Type 3.
Connection conditions for the multi MPPT operating mode
■■ It is not permitted to install a ground connection to the PV generator.■■ Starting from three DC feed lines for each power unit, the minimum cross section
increases because in case of a short circuit the two intact feed lines pass on all the return current to the defective line (the cross section increase for three DC feed lines can be dropped if all the DC feed lines are fitted with fuses):
Number of feed lines per power unit Minimum cable cross section
1 95 mm2
2 50 mm2
3 70 mm2
28
Connection conditions for the single MPPT operating mode
■■ Minimum conductor cross section: 95 mm2
■■ All the DC inputs of the inverters in use must be connected in parallel.■■ The DC bus bars for connecting the inverters in parallel must be dimensioned for the
maximum current:
Number of inverters Maximum current in the DC bus bars [A]
2 720
3 960
4 1 440
■■ All DC feed lines must be individually fitted with fuses, both at the plus as well as the minus pole. Use 160 A NH fuses which have been certified for at least 1 000 VDC (the 160 A correspond to the max. DC total current of a MaxConnect combiner box).
■■ Installation of a ground connection to one pole of the PV generator is permissible (plus or minus pole).
DANGER
Fatal electric shock hazard! – When a pole of the PV generator is grounded (or func-tionally grounded), that pole must be considered as live and must be insulated.

5.3.6 Connecting the shutdown contact 1 (optional)
Position of the shutdown contact 1 (SD1-SD4) in the inverter: see 5.3.1 “Interior view”.
The shutdown contacts 1 (SD1-SD4) enable remote shutdown of as many as eight inverters using an external break contact (e.g. an emergency off switch). If the shutdown function 1 is activated the current supply circuit of the AC contactor K1 is disconnected directly and the inverter is locked. This results in the immediate disconnection from the grid which is also effective when the control unit fails. The inverters remain locked until the external break contact is reclosed. In addition, the status message “Shutdown 1” is displayed.
The shutdown 1 is inactive if there is a short circuit between either the contact pair SD1 and SD2 (SD12) or SD3 and SD4 (SD34), e.g., with a plaited bridge. The shutdown 1 is only active if both contact pairs SD12 and SD34 are open. When shipped from the factory the contact pair SD12 is short-circuited with a plaited bridge.

5.4.6.3 Shutdown contact 2 – X511
The shutdown contact 2 (X511) allows the inverter to be remotely shut down via an external break contact. The function is similar to the one of shutdown contact 1, but the separation from the grid is not made directly via the supply voltage of the AC contactor K1. It is controlled by software via the inverter’s control unit. The inverters remain locked until the external break contact is reclosed. In addition, the status message “Shutdown 2” is displayed. The shutdown 2 is inactive, if EN1 and EN2 (EN12) are short-circuited by a bridge (condition at the time of delivery). The shutdown 2 is active if the contact pair EN12 is open.
5.4.6.4 Alarm contact – X501
The alarm contact (X501) is used to display the status of the generator connection box MaxConnect plus in the graphics display. For this purpose use a two-wire cable to connect the contacts of the potential-free fault alarm output of MaxConnect plus to the STM and GND contacts on the inverter’s terminal block. As soon as the STM and GND contacts are short-circuited, the inverter display shows the status message “Warning MaxConnect”.
5.4.6.5 Connection PAS - X2201
Interface for the connection of the potential equalization set (PAS). Use the cable supplied with the potential equalization set.

5.6 Connecting the other station components
The correct electrical installation of the following components is in the hands of the sta-tion outfitter. SolarMax Produktions GmbH instructions in this regard are limited:
AC circuit breaker
To protect the inverter and to permit its complete AC-side disconnection, an AC power switch must be connected to the AC connection of the inverter.
Specification AC circuit breaker:
■■ Maximum current: 800 A■■ Maximum voltage: 280 V (SM330TS-SV) / 320 V (SM360TS-SV)■■ Thermal and magnetic overcurrent release
Alternatively, an NH switch disconnector fuse with 800A NH fuses may also be used.
Medium voltage transformer
Standard values for dimensioning and typical characteristics can be found in 3.4.3 “Medium-voltage transformer”.
Autonomous power supply transformer
The star point on the secondary side (400 V) must be earthed. On the primary side (280 V / 320 V), no star point is necessary. The autonomous power supply transformer must be fused on the primary and secondary sides.
43
en
5.7 Application examples for single-MPPT operation
This section shows two examples of applications using three SM330TS-SV inverters and a TS-SV-MCU in each case. Both stations are designed for single-MPPT operation.
In the example in subsection 5.7.1 three DC bus bars are used. One DC bus bar for every central inverter. The DC bus bars are connected to each other with connection cables. The 315 amp fuses protect the connection cables. If the currents are balanced, no current flows in the connection cables. If the currents are not balanced, the current in the con-nection cables will not exceed 315 amp. The 315 amp fuses allow individual inverters to be disconnected from the DC input.
In the example in subsection 5.7.2 all DC inputs of the central inverters are connected in parallel to a common DC bus bar. In that case, the connection cables are not necessary. The 315 amp fuses can be dropped. Arrange the connections over the entire length of the DC bus bar, so that the current at a certain point cannot exceed 960 amp.
DANGER
■■ Only qualified electricians who have already completely read and understood this installation manual in advance may install and open SolarMax inverters.
■■ The qualified electrician is responsible for adhering to the valid local application installation and safety instructions.

CAUTION
Before you switch on the inverter, fit all the available protective covers, cover plates and perforated grids. The AC and DC power switches, and the main switch, can be operated from outside the closed device.
6.2 Commissioning (Initial Setup)
If the inverter is being commissioned the initial setup will start automatically. This pro-cedure must only be carried out once as part of the commissioning process. Information about operating the display is contained in the operating manual of the TS-SV inverter.
1. Switching on the inverter Switch on the MCU and the inverters as described in the operating manual of the
TS-SV inverter.
2. Selecting the display language In this step select the language in which the following information and texts in the
display will appear.
3. Selecting the individual country settings The individual country settings permit making such settings as the required mains
voltage and mains frequency range used in the country of installation. The selection of the country of installation is independent of the selected display language.
4. Date and time Set the local time and current date. The date set is stored as the commissioning date
and can be accessed later in the “Information” menu.
5. Confirming the entries Now confirm the completion of the initial setup with the button .
52
CAUTION
The individual country settings (step 3) must be entered with extreme care. Once the initial setup is completed the selections are permanently set and can no longer be modified. A wrong selection can lead to problems when operating the inverter and result in the license to operate being revoked by the local grid operator. An overview of the available country settings are contained in the operation manual of the TS-SV inverter.
NOTE
You can change all the settings in the initial setup (with the exception of the individual country settings) at any time in the “Settings” menu.

7.2 Temperature-dependent output reduction
The inverter can feed 100 % of its rated output for an unlimited time up to an ambient temperature of 45 °C. In the temperature range from 45 °C to 50 °C yield losses have to be expected, at 50 °C the inverter can still feed in 90 % of its rated output for an unlimited time. For this reason ambient temperatures exceeding 45 °C must be strictly avoided.
