89 2.0 Information on installation.
Electrical safety Before opening the cabinet, the solar inverter must be disconnected from the grid and from the PV generator . The solar inverter continues to conduct a hazardous voltage internally and at the connection sockets for the PV generator for ca.
91 EN Information on cleaning Before cleaning, disconnect the system from the power grid by opening the grid breaker (main fuse) and open the DC switch on the PV generator , in order to exclude the danger of electric shocks. Use a soft, dry cloth to clean the system.
2.2 Installation The solar inverter must be installed by a trained, qualified electrician. A special tool is necessary for installation. Please read this chapter very carefully .
93 EN If installing the solar inverter in a switch box, ensure adequate heat dissipation. The ambient temperature must not fall below or exceed –25°C or +40°C. The solar inverter should not be exposed to direct solar irradiation, so as to protect it from unnecessary external heating.
Electrical connection and cable entry For installation, please observe the instructions in the "Setup" leaflet! 94 ! If the solar inverter is fixed to the installa- tion frame, the electrical connection can be led through. The unit may only be ope- ned by a qualified electrician.
95 EN Grid connection The grid connection of the solar inverter must have 5 wires (L1, L2, L3, PE, N). Cable cross-sections of 5 x 4 mm2 are recommen- ded. The solar inverter is connected to the supply grid via the circuit board terminals inside the unit.
96 Y ou must use adequately dimensioned cable cross-sections in order to avoid a considerable increase in the grid impedan- ce between the domestic distribution and the solar inverter . The terminal range of the AC terminals is 0.5 to 6 mm2 for rigid cables and 0.
97 EN PV generator connection · Preparation Execute the DC cabling according to your electrician's system dimensioning. Check each PV string for correct functioning by performing a no-load voltage current and short-circuit current measurement.
98 Important information · The direct PV generator voltage is availa- ble internally after connecting the PV generator to the solar inverter via the DC connectors and switching on the PV generator sw.
99 EN · The DC voltage can be up to 750 V . The unit may only be opened by a qualified electrician! · Always disconnect the PV generator side first by opening the PV generator switch, and then the g.
100 Communication connections V ia the communication connections (inter- faces), operating data can be retrieved from the data memory with an external computer and specific operating settings made.
101 EN · Connection Remove the cover of the solar inverter before connecting an interface cable. Pay heed to all safety hints (Pages 90 and 91). Y ou will find the necessary cable terminal block with the RS 485+, RS 485-, GND_G, TX, RX, GND_G, TX 2, RX 2 connections on the board in the centre, bottom left (see figure on the left).
102 Connecting the sensors · Optional irradiation sensor The optional addition of an irradiation sensor (type Si-01TC-T from Ing.-Büro Mencke & T egtmeyer ) with integrated PT -100 temperature s.

104 2.3 Commissioning Connect the solar inverter internally via the ground cable (yellow-green) to the cabinet cover . (See also Setup, step 7) Put the cabinet cover on. Screw it down tightly with the four screws on the front. Do not place any objects (e.
EN 105 in cloudy weather . This is normal, and does not affect either the yield or the mode of functioning of the solar inverter . · Switching off Disconnect the PV generator side first by opening the PV generator switch, and then the grid connection by isolating the relevant mains fuse.
However , language setting, LCD contrast and total energy offset (only to be used in the event of replacement) must be configured directly on the unit.
107 EN This is the only exception for which work may be performed on the open unit under voltage! Remove the cabinet cover to carry out the configuration. The following settings can be performed using the illustrated keys: PLUS UP/DWN RST Fig.: The setting keys are located beneath the display .

3.1 Monitoring and diagnosis Display The dot matrix LCD display is integrated into the cabinet of the solar inverter so that it is easily visible. The display consists of 16 characters and 2 lines. The top line 1 shows the current feed-in power of the solar inverter .
Data memory Y our solar inverter is equipped with an internal data memory as standard. This data memory provides you with a detailed view of the mode of functioning and the relevant values of your solar power supply at all times. Y ou can access these data with the help of the NT Monitor software described below .
113 EN 3.2 Sunways NT Monitor software General information The Sunways NT Monitor visualisation soft- ware was developed for PV system monito- ring and configuration of the solar inverter using PC. It is contained on the enclosed CD and can also be downloaded free of charge on the Internet from www .
114 from ICP-Deutschland, (available from your specialist dealer), which will guarantee reliable data transfer . The addresses of the solar inverter must be input in the solar inverter using the Sunways NT Monitor software or input directly with the keys illustrated on page 107.

(3) PV system for 2 to 99 solar inverters with interface converter (I C) Connection to PC via RS 485 / RS 232 In order to connect several solar inverters to a PC, the RS 485 signal is looped thr ough from inverter to inverter , until it is led into the inter- face converter .
118 The signal is looped through all units. T wo «RS 485+» terminals and two «RS 485-» terminals are located on each terminal block. This means that the signal can be led into the solar inverter at one terminal and out of the solar inverter at the other termi- nal.

123 EN Operation of Sunways NT Monitor After installing the Sunways NT Monitor software on your PC, you can start the program. The word «Sunways» will now appear on your screen. On the menu bar at the top, you will see the four menu areas «Program», «Data», «Settings» and «Help».
124 Y ou can call up «Daily values» and «Monthly values» in the same way , by clicking on the respective keys. Exit the window with the «Close» key . Y ou will return to the «Settings» menu. · Help menu Y ou will find further helpful information on operating the Sunways NT Monitor software in the «Help» menu.
3.3 Fault indications Y our solar inverter operates fully automati- cally and maintenance-free. However , if operational faults occur due to external or internal causes, these will be displayed on the screen. · AC over/undervoltage (3-phase) Y our solar inverter monitors the limits of minimum and maximum permissible 3-phase grid voltage.
Display for AFI error protection: · Overheating fault Y our solar inverter is designed for an ambient temperature of up to +40°C. When the maximum upper temperature threshold is reached, the feed-in is stop- ped. When the heat sink temperature has decreased, the solar inverter starts up again automatically .
127 3.4 Fault diagnosis Fault display Overtemperature UDC Overvoltage Causes The maximum permissible ambient temperature of 40°C has been exceeded. The necessary air circulation was not taken into account during installation. Objects have been stored on the heat sink, impeding free convection.
128 Fault display UAC_1 UAC_3 AC under/over- voltage Causes The grid voltage is too low or too high. The cable cross-section in the AC feed line to the solar inverter is too small. Y our solar system feeds into a spur line, which is inade- quately dimensioned.
129 Fault display AFI Residual current Incorrect time, date are stored in Sunways NT Monitor with incorrect time data. Causes The AFI error is displayed if a residual current has occur- red in the PV system and the solar inverter has sub- sequently disconnected from the grid.
3.5 W arranty terms and conditions · W arranty period The warranty period is five years from purchase of the solar inverter by the end user . Please complete the enclosed war- ranty card and return it to Sunways AG. Please keep the original invoice with the date of purchase in a safe place.
131 EN · Exclusion of liability W arranty claims and liability are excluded for direct or indirect damages due to: · Interventions, modifications or attempted repairs · Inadequate ventilation · Force majeure (e.g. lightning strike, water damage, vandalism, fire, overvoltage, thunderstorms etc.
