2 GENERAL DESCRIPTION 2.1 Introduction The ZIGOR SOLAR XTR3 is a single phrase solar inverter. It is responsible for converting the direct current generated by photovoltaic panels into alternating current for injection into the electrical power distribution grid. The ZIGOR SOLAR XTR3 can be used both to back up consumption and as a system to produce electricity. In the first case, if the electrical power consumption of the location in which the inverter is installed is lower than the power consumed by this unit, excess production is delivered to the grid. If this consumption exceeds production, the energy required to complete the balance is taken from the electricity grid. In the second case, all the power generated by the equipment is injected into the electricity grid. In both cases, the appropriate power measurement systems must be installed for each use. The installation of the ZIGOR SOLAR XTR3 and its connection to the electricity grid shall be done in accordance with local regulations and may require the installation of adequate electricity consumption measuring devices. The PV inverter only operates when it is connected to the electrical power distribution line and cannot operate as a stand-alone unit.

Do not use cables where losses will exceed 1%. R (L1), S (L2) , T (L3), N and Gnd : 4/6mm2 cross-sectional area wire.

Step 4. Remove the bottom cover of the inverter where AC terminals are by unscrewing the 3 screws that hold it, 2 near the fans and the other in the opposite side (as it is illustrated in the below figure). Due to the air seal located between the inferior and superior cover, placed to avoid the entrance of liquids in the system, the extraction of the inferior cover can be difficult, for it, also clears the screws of the indicated superior cover n the following image and this one will leave with extreme facility.

Fig. 3-7 Location of the screws

Step 5. Insert AC cables through the gland located on the left bottom corner, through rubber bushing, and AC-output cover. Then, insert Ground through the same enclosure. Step 6. The choice of cable together with the way it is routed, the ambient temperatures the inverter operates at, and other underlying conditions determines the maximum AC fuse protection used for the inverter.

6 COMMUNICATIONS INTERFACE 6.1 Access remote WEB (http) To communicate with the system, by the website, some settings have to be done previously. First of all, the system has to be connected by an Ethernet cable to the router. In the lower part of the system, there is the communication board: starting for the left side, there are: an Ethernet connector, two R115 connectors, and one USB connector (for ZIGOR exclusive use only).

Fig. 6-1 Communication Board

There is NO user installable software. The system is accessed by an internet explorer and it is used the same user interface for local mode and remote mode. When the wires are connected, the network has to be configured. There are two options; first, the router assign an IP to the inverter (DHCP: Dynamic Host Configuration Protocol) or configure it manually. Second, involves the configuration of the subnet mask, router and primary DNS. Note: It is required Internet Explorer 8 or higher or Mozilla Firefox 3 or higher. Note: There are some parameters that can be modified by the user; and another parameters, for your safety, that the manipulation is exclusive for ZIGOR maintenance workers.

6.1.1 Configuration by DHCP In the default configuration, the inverter is configured without DHCP. To enable, it has to be done from “settings” menu, “system” and in the 15th point is the option of “enable DHCP”, change the status to activate (“yes”). When this process has be done, go to “control” and in the fourth point “net”, select “IP NEW” and accept. The inverter will reset and it will be configured automatically for connecting by web. In this case, the inverter will have an IP direction that it has to be known, so the communication could be possible. It is located in the router (depends on the router) or from the inverter, being more easily this second choice To get the IP by the inverter’s screen, go to the “status” menu, “system” and annotate the IP. To do the communication, put the IP direction in the web navigator.

6.1.2 Configuration without DHCP In the default configuration, the inverter is configured without DHCP and with one IP direction, mask, router and primary DNS at random. Some admissible directions will have to be inserted manually, depends on the place will be connected. So the user manual of the router has to be looked up, and in case of doubts consult to your telephone service provider.

6.1.3 Configuration for external connection The steps haves been described for the connection of the inverter to one telephone network can only be used for doing the communication in the same network. To connect from computer that it isn’t connected to the same router but with Internet connection, one port in the router have to be opened. For more information you will have to consult to your telephone service provider.
