It converts direct current generated by the photovoltaic modules into symmetrical, threephase alternating current and supplies it to the public power grid. Power generation independent of the public grid (island operation) is not possible. 10 Through three-phase technology, PIKO 4.2/5.5/7.0/8.3/10.1 unite the stability and durability of central inverters with the flexibility and the high degree of efficiency of transformer-less string inverters. In order to improve the degree of efficiency, PIKO 4.2/5.5/7.0/8.3/10.1 with a lower input power (less than 10 percent of the rated output) use only one or two phases for current feed-in. The device selects the phase on a random basis each time. The PIKO inverters are fitted with an integrated DC switch. No external break switch is therefore required, unless specified by local country laws (example France). The solar modules are connected to the inverter via plug-in connectors. The inverters PIKO are available in various output sizes (see table 22, page 50) and offer you maximum flexibility in configuring your solar energy system. This is achieved through a broad DC input voltage range, independent MPP regulators for each input, which enable the connection of solar modules in various combinations (alignment, inclination, quantity, type). In order to conveniently display the yields and production data of your photovoltaic system, the inverter has an integrated web server, see chapter 8.8.1. 05/2013 | DOC01318011 | Operating manual for PIKO inverter 4.2 - 10.1 7 Unit and system description Arc detection Acknowledge malfunction Arcs can occur in a PV system. These arcs can cause damage. The inverters PIKO 7.0 AD/8.3 AD/10.1 AD are equipped with arc detection. The DC break switch must be switched off and on again in order to acknowledge the error message. The inverter then starts normally. When an arc occurs again, the inverter behaves as previously described. Arc types There are two kinds of arcs: — Serial arcs — Parallel arcs Serial arcs occur on damaged DC lines or at loose contact points. These arcs occur more often in PV systems than parallel arcs. Parallel arcs can occur between the plus and minus pole of the system or at individual sub-generators. Arcs are dangerous. For one thing they destroy the components upon which they occur and high temperatures can also trigger a fire in the PV system. The arc detection monitors the PV system for arcs. It determines the string in which an arc is occurring. The arc detection differentiates between serial or parallel arcs. In the event of a serial arc, the inverter shuts off the relevant string. This extinguishes the arc. A parallel arc is issued as an error message. Because it is not technically possible for an inverter to delete a parallel arc, this is only shown as a message in the display. The signal tone also sounds and the red LED lights up. The message disappears in the display once the error message is acknowledged. Note: The entire installation of the PV system should be checked for damage after each event message referring to an arc. Inform your installer where appropriate. Note: In rare individual cases, false alarms can occur that can be extinguished outside of the PV system. Causes for such false alarms can include, for example, transformer stations or large energy consumers. IMPORTANT: Under certain circumstances (e. g. with feed cables >60m), arcs cannot be registered. This is why regular maintenance of the PV system is essential. Regular inspection of the installation must be carried out despite arc detection! "Arc" fault When an arc occurs, an event message referring to this appears in the display. The red LED is permanently lit, the yellow LED blinks in a 5-second rhythm and a signal tone is heard. The inverter switches off the relevant string. After 30 seconds, the inverter attempts to switch on the relevant string again. When the inverter recognises an arc four times within a period of 30 minutes, it shuts off the defective string entirely. The arc detection can be deactivated with the communication board II menu (default "On"). The occurring malfunctions are recorded in the inverter. 05/2013 | DOC01318011 | Operating manual for PIKO inverter 4.2 - 10.1 11 7 Unit and system description 3 1 6 7 5 4 2 Fig. 6: System illustration of a grid-connected photovoltaic system 1 2 3 4 PV string 1 PV string 2 and 3 (optional) Inverter Electronic DC switch 5 6 7 AC mains cable 3-phase AC line circuit breaker (for layout, see table 6, page 18) Feed meter Inputs Internal consumption The PIKO operates using the so-called string principle: In this system, a limited number of solar modules (depending on the desired power output while considering the maximum permissible input voltage) are connected in series as a string, which is then connected to the inverter. The number of strings depends upon the configuration of the solar system. The strings are connected to the inverter with plug-in connectors. The PIKO inverters are designed in such a way that the generated current can be used internally either entirely or in part. Depending on the device type, one, two or three separately controllable inputs are available. Inputs one and two can sometimes be connected in parallel in order to allow a higher input current (see table 7, page 19). For PIKO 5.5, parallel connection is not possible. Photovoltaic module Inverter Production meter Consumption meter Grid Control signal Jumper switch External load relay You can obtain the highest yields through the maximum permissible input voltage. This is achieved by using the smallest possible number of inputs with identical power. An example: For the installation of 48 solar modules, it is better to use two inputs with 24 modules each rather than three inputs with 16 modules each. Be sure to always observe the specifications on the type plate! Feed meter Consumer devices Fig. 7: Possible configuration for internal consumption The switch output is a potential-free NO switch. Note: An external load relay must be installed between inverters and devices. No devices may be connected directly to the inverter! You can find the description for the electrical connection in section "Connect switch output (S0/Al OUT)" on page 29. You can find the description of the S0 output configuration for the control of internal consumption in section "Setting the switch output function" on page 34. 12 05/2013 | DOC01318011 | Operating manual for PIKO inverter 4.2 - 10.1 7 Unit and system description Active power and reactive power control The terms There are three types of electrical power in the mains grid: — Active power (W) — Reactive power (Var) VDE application rule (VDE-AR-N 4105) and Renewable Energies Act (EEG) 2012 New application rules for PV systems have applied in Germany since 1 January 2012. The VDE application rules (VDE-AR-N 4105) and the Renewable Energies Act (EEG) are compulsory. The PIKO inverters satisfy the currently required standards and guidelines. Note: Should the PV system not fulfil the Renewable Energies Act (EEG) 2012, the grid operator can reduce the feed-in tariff or dispense with it entirely. — Apparent power (VA) Active power Active power is that electrical power that is converted by an ohmic device. Ohmic devices are devices with no coils and capacitors (e. g. heat radiators, electric stoves, light bulbs). The active power is registered by the usual electricity meters. This means that only the active power is calculated or paid for. The following points are relevant when implementing the new application rules: The active power current is "in phase". This means that current and voltage are synchronous. Both reach the zero point and the peak value at the same time. — Fixed limitation of the feed-in power to 70% of the PV output — Frequency-dependent active power control — Active power control with a ripple control signal receiver — Provision of reactive power — Regulating of unbalanced loads Reactive power Reactive power is that electrical power that is converted by inductive and capacitive devices. Inductive devices are coils. Capacitive devices are capacitors. These devices require electrical energy in order to build up the magnetic or electrical field. This power is referred to as reactive power. Devices with motors and capacitors (e. g. washing machine) draw reactive power from the grid. The reactive power is not registered by the usual electricity meters. However, like the active power, it does draw from the mains grid. The reactive power current is "out-of-phase". That means that current and voltage reach the zero point and the peak value at different times. Apparent power Apparent power is the total output, consisting of real and reactive power. The calculation of electrical power takes place through the geometrical addition with the angular functions (cosϕ, sin ϕ and tan ϕ). Frequency-dependent active power control To date inverters are to be immediately disconnected from the grid when they exceed the upper frequency limit of 50.2 Hz. Grid stability can be negatively impacted by the abrupt switching off of large generation plants. Hence the need for an active power reduction solution in the event of overfrequency. This means that inverters need not be disconnected from the grid when exceeding 50.2 Hz, but instead that the active power must be reduced. This active power is then reduced by 40% per Hz. When the frequency reaches 51.5 Hz, the inverter must be immediately disconnect from the grid. Active power control with a ripple control signal receiver The active power of the PIKO inverter can be controlled directly by the energy supply company via a ripple control signal receiver (1). With this technology, the generated power can be regulated at four levels (see Fig. 8). Displacement factor cosϕ The size of the real, reactive and apparent power can be determined with the displacement factor cosϕ. The smaller the cosϕ factor is, the less the active power and therefore the greater the reactive power. Note: The displacement factor cos ϕ can be set with the parametrisation software PARAKO in order to define the magnitude of the reactive power.

Remote retrieval of the current yield/power values and/or saved log data. 22 05/2013 | DOC01318011 | Operating manual for PIKO inverter 4.2 - 10.1 8 Installation Situation 1: Configuring the inverter All settings relating to communication, for example, activation of data transfer to a solar portal, can be selected directly via the display or the integrated web server. In order to access the web server for configuration, you require a computer that is connected to the inverter either directly or via the network. The inverter is equipped with two Ethernet interfaces (RJ45 sockets) for this purpose. The computer must also be equipped with this type of interface. The operating system is irrelevant, as the web server is called up via an Internet browser (e. g. Mozilla Firefox, Microsoft Internet Explorer). You can then connect the inverter and computer either a) directly via an Ethernet cable (see illustration 31) or b) via a local network (switch/hub/router and Ethernet cable, see figure 29). 1 2 3 4 Fig. 30: Several inverters in the network 1 2 3 4 5 Version a) is the best option when no switch/hub/router is available.

The units are cabled as described under situation 1. The inverter can send yield data to an Internet solar portal at regular intervals. Alternatively, you can connect the inverters to each other via the RS485 interface and then need only connect one of the inverters via Ethernet (figure 32). a) the inverter must be connected to a DSL router or to a network with Internet access or With this type of connection, the web server of the inverter connected via the Ethernet also displays the current output data of the other inverters. However, the web server and the stored log data are only available for the inverter connected via Ethernet. b) the inverter must have an integrated wireless modem (GSM) available as an accessory. 1 Version a) requires a DSL connection. If your inverter is located close to the building and you already have a DSL connection, you can use the available connection for transfer. In the case of data transfer via DSL, a max. of 300 inverters can be networked. Note: If the inverters are connected to the Internet by DSL router in the local network, both direct retrieval of the log data as well as transfer of the log data of all connected inverters is possible through a solar portal. 2 3 4 Version b) 5 6 Fig. 32: Connect inverters via the RS485 and retrieve performance data via Ethernet 1 2 3 4 5 6 To do so, Inverter Additional inverters, max. 200 depending on cable length RS485 connection Ethernet/crossover cable Switch/hub Computer To transfer the data to a solar portal with a modem, first connect the inverter via the Ethernet/crossover cable. You will only need one modem: the inverter with the modem then assumes the function of a router for the other inverters. For version b) with a wireless modem, you will require a SIM card from a mobile phone provider. There must also be adequate wireless reception at the point of installation. Make sure that the APN (access point name) is set correctly. To do this, use the "Settings" page in the "GSM-Link" configuration tool (see section Installing GSM modem). You will find a detailed description on our website. ATTENTION Inadequate reception quality, e.g. in areas with weak network coverage, can lead to connection problems and to the GSM modem dialling into the grid too often. Depending on the price model of the GSM contract, this can result in increased costs. 24 05/2013 | DOC01318011 | Operating manual for PIKO inverter 4.2 - 10.1 8 Installation The reception quality is also affected by the weather. We recommend testing the reception with a normal mobile telephone for a few days prior to installation to ensure that adequate reception is possible despite differing weather conditions. Situation 4: Remote retrieval of yield data You can also connect to the inverter remotely instead of through a local network. This may possibly involve additional connection costs. Similar to situation 3, the inverter must either Note: The maximum cable length of the GSM antenna is 8 m! a) be connected to a DSL router or The number of inverters that can be networked is in principle only limited by the available IP addresses. In practice, a maximum of 30 inverters can be networked when transferring data via a GSM modem. Version a) Inverter with DSL connection to the Internet b) have a modem (GSM) installed. To ensure the inverter can actually be accessed via the Internet, several requirements must be met. — The inverter must have a fixed IP address in the local network. 1 — Port forwarding must be configured to the inverter IP address in the router. 2 3 4 WWW 5 Fig. 33: Connecting several inverters through the Ethernet and transferring data via modem 1 2 3 4 5 Inverter with an integrated modem (GSM) Additional inverters (without a modem), max. 29 Ethernet/crossover cable Computer (for configuration and, if applicable, direct retrieval) Mobile communications antenna Note: For installations with several (max. 30) inverters, you will only need one modem. — The router must be assigned a fixed IP address by the Internet provider or you must register the router with a DynDNS service to connect the dynamic router IP address with a fixed name. The inverter can then be accessed over the Internet under the domain name provided by the DynDNS service, and you can connect to the inverter with any Internet browser (see figure 34). Setting up a port forwarding and a DynDNS service can't be illustrated in detail here due to the vast number of different devices and services available. Note: DynDNS services can also be found under the designation "Dynamic DNS" and "DNS-Host-Service". In order that the router can be reached under the selected domain name, it informs the DynDNS service of each IP address change. Many of the available routers offer such a function, but a router generally only supports certain DynDNS services. With some router manufacturers the function for port forwarding is called "Virtual Server" or similar. For further information see the operating instructions of the router. 05/2013 | DOC01318011 | Operating manual for PIKO inverter 4.2 - 10.1 25 8 Installation 1 5 3 WWW 2 4 Fig. 34: Retrieving log data: Inverter connected to the Internet via DSL 1 2 3 4 5 Inverter DSL router Internet Computer Internet-compatible mobile phone with browser function Version b) with an integrated modem Dialling in with a computer and analogue telephone connection does not function reliably for an inverter with GSM modem. We therefore recommend dialling in via a computer with a GSM modem or a mobile telephone with a modem function (see figure 35). 1 In order to use the GSM modem, you will need a SIM card with a contract with a mobile phone provider. The GSM-Link software leaves you free to select your mobile phone provider. Using a modem involves additional costs. Details can be obtained from telecommunications providers. Not every mobile phone tariff is suitable for use with an inverter! Before purchasing the SIM data card, discuss the following points with your mobile phone provider and obtain all the access data you require (APN, user name and password). — You should select a provider whose grid supplies the strongest GSM signal at your chosen location. — The tariff must allow for packet data communication via GPRS. — Prepaid cards which are charged by mobile calls are not suitable. — Tariffs which specify particular times for data downloads cannot be used. — The tariff must permit a data volume of at least 5 MB per month and inverter. 2 — The SIM card must be activated before installation. 3 4 Fig. 35: Retrieving log data: Inverter connected to a mobile communications network 1 2 3 4 Installing GSM modem Inverter with integrated GSM modem Mobile communications antenna Mobile telephone (GSM) with modem function Computer • Switch the inverter off for at least 5 minutes, see chapter 9.4 ‹Disconnecting the inverter /decommissioning›.

DANGER Risk of death due to electrical shock! Deadly voltages are present in the inverter. Only a qualified electrician may open and perform work on the device. If the fuse has tripped, notify the installer; if there is a power failure, simply wait until the grid operator has corrected the problem. If the fault lasts only a short time (mains fault, overheating, overload, etc.), then the inverter will automatically resume operation as soon as the fault has been resolved. If the fault persists, notify your installer or the manufacturer's customer service department (for contact information, see back page). Provide the following information: — Device type and serial number. You will find this information on the type plate on the exterior of the housing. — Description of fault (LED indicator and display message). 44 05/2013 | DOC01318011 | Operating manual for PIKO inverter 4.2 - 10.1 10 Inverter operating characteristics Event list There is no need to take action when a fault occurs occasionally or only briefly and the device resumes operation.

The inverter regularly records performance data (voltage, power, energy) of the DC and the AC side. Note: Some of the data will also be shown on the inverter display during operation (see chapter 10.4). There are two ways of retrieving, displaying and permanently saving all log data: — Transfer the log data to a solar portal. — Download the log data with a computer. You can, of course, make use of both options together. Transfer the log data to a solar portal. The inverter can transfer its log data automatically and at regular intervals to a solar portal in the Internet. The data transfer may incur additional costs. As a rule, you must register the inverter with the solar portal operator. You can find further information at our service hotline. See also chapter 9.2.1. The solar portal displays the data on an Internet page and archives them. This enables you to view the status of your photovoltaic system at any time and from anywhere. All you need is access to the Internet (computer, Internet hotspot, mobile phone, etc.). Downloading the log data onto a computer. Retrieve the performance data of your photovoltaic system directly from the inverter. To do so, establish a connection to your inverter with a computer. The integrated web server displays the current performance data clearly on HTML pages so that you can access the data with any conventional Internet browser. No special software is needed. You can also download all saved log data and display it using the free visualisation software PIKO MasterControl (see chapter 11.3). Alternatively, you can use a spreadsheet application. 11.1 Logging into the web server • Switch on your computer. • Only for dialling in via GSM modem: Establish a dialling connection to the modem in the inverter. Note: Ensure that the proxy server for LAN connections has been deactivated. You can find further instructions concerning network settings in the operating system manual for your computer. • If your computer is connected to the inverter via a network cable, enter an "S" into the address line of the browser, followed by the serial number of the inverter (see type plate), for example http://S12345FD323456 ➜ The log-in window for the web server opens. • If your computer is connected to the modem in the inverter via dial-up connection, enter the letters "wr.S" in the browser's address line followed by the serial number of the inverter (see type plate), for example http://wr.S.12345FD323456 ➜ The log-in window for the web server opens. Note: Instead of the serial number, you can also use the name of the inverter or the IP address, for example http://name or for a dial-in connection http://wr.name or http://192.168.1.51 (if the inverter has this IP address). You can find out how to allocate a name to the inverter or to change the name in section ‹Changing the name› in chapter 9.2. • Enter user name and password.
