1. Introduction This manual describes all the information needed to install and operate an Eaton PV240, PV250, PV260 and PV270 grid-tie PV Inverter (“PV Inverter”). IMPORTANT In order to avoid problems during the install procedure, it is recommended to read the entire user manual before starting any install procedures. Any improper usage may result in damage to the unit.
2. Limited Warranty Eaton grid-tie PV Inverter comes with a 10-year warranty. This warranty covers all defects due to design, manufacturing and components.
4. Product Overview 4.1 Introducing the Grid PV System The grid-connected PV system is mainly composed of four parts: the PV-modules, the gird-tied PV Inverter, the AC-Connection Unit (the connection Interface) and a connection to the Public Utility. When a PV-panel is exposed to sufficient irradiation and connected to an inverter, it generates DC power. The PV Inverter converts DC to AC and feeds in to the Public Utility via the AC-Connection unit.
4.2 Introducing Eaton Grid-Connected PV Inverter Eaton grid-tied PV Inverter converts direct current (DC) power generated by a PV panel into alternating current (AC), which is compatible with the local electrical distribution network; also called the public utility, or grid system. The Eaton grid-tied PV Inverter is designed with a transformer less topography.

See framed area below. Figure 6.2.
G. DC Protection This is the over current and over voltage protection that is used for the Direct Current (DC) side. According the NEC 690.15-18, fuse holders can be used to disconnect the PV modules for serving. The Eaton grid-tied PV Inverter is shipped with dummy fuses (solid aluminum cylinders in the shape of the proper fuses).
The standard formula for DC Fuse Selection: Nominal Voltage of fuse must be 600VDC Rating and the fuse should be selected between 1.56 x Isc < IN Assume the maximum short circuit current (Isc) of the solar module used is 4.85A. The rating of the selected fuse must have a nominal current greater than 1.25 times but less than 1.6 times the short circuit current as 1.56 x Isc < IN Calculated by Standard Formula: A) 4.85A x 1.56 = 7.56A B) Implemented the above result within 1.
H. DC Input Terminal Block It is the terminal block that used to connect the DC cables from the PV modules. In order to have a trouble free connection, it is recommended to connect PV modules of the same type, same quantity, with an identical configuration of strings. However, the size selection of DC cables should be refer with cable size requirement in the National Electrical Code(NEC), ANSI/NFPA 70 in order to select the proper size of DC cables can be used with the PV inverter. I.
K. Utility Configuration DIP Switch It is a utility configuration dip switch that is embedded within DC/AC wiring box. This dip switch allows the user to do different configurations of the PV Inverter in order to let it connect to the different public grid systems using the same inverter. The dip switch is located at the right-bottom side of wiring box, which just under RS485 interface card and nearby the RS232 interface port as below shown in figure 6.2.15: Figure 6.2.
L. RS232 Interface (for service purpose) The Eaton gird-tied PV Inverter is equipped with a versatile communications interface and can be used with a stand-alone monitoring software called “Pro Control” to monitor the operating status of a single PV inverter or multiple PV Inverters through RS485 or RS232 interface. To active the RS232 interface, the RS485 interface card should be disabled manually by switching off the SW2 DIP switch as below figure 6.2.16 indicates.

In order to utilize an opening hole in the inner level area, it is necessary to use the required tools such as a slotted screwdriver with a hammer to knock at the certain point repeatedly as figure 6.4.6 indicated: Figure 6.4.6: Knocking point of inner level 1st Step: 2nd Step: Last Step: Use tools to target upper strick point and to knock once. Use tools to target bottom strick point and to knock again. Repeat the1st and 2nd step until the hole of inner level is opened.
7. Connecting the PV Inverter 7.1 DC Wiring Connections Since the wiring box has been opened during mounting procedures, please use the proper tools to knockout an opening hole in the desired location from wiring box for AC cables and then inserted a conduit and fixed it with the pipe end fitting as shown in figure 7.1.1. If the top cover of the wiring box is not removed yet, please remove the top cover of wiring box before this procedure started. Figure 7.1.
iv. Use multi-meter to confirm the total input power of PV strings in order to ensure the input power from PV string will not be exceed the permission setting 600VDC as the maximum operating voltage according to electrical specification of PV inverter and the maximum DC input current should be within 20A to each pole of DC terminal. IMPORTANT Configuration of the PV modules should be done by qualified service personnel with the instructions that are provided from the manufacturer of the PV modules.
C) Connecting DC cables of PV strings to the DC terminal by following the steps below: DC - DC + Figure 7.1.4: DC terminal for PV inverter i. Select the proper rating for the string fuse by following the calculation that had been mentioned in section G. DC Protection of chapter 6.2 ii. Install the DC fuse in its assigned location iii. Connecting DC positive polarity cable to the DC positive pole terminal in the wiring box iv.
WARNING Do not mix the connection with the wrong polarity. This may cause damage to the PV Inverter; therefore, it is very important to do the polarity check before connecting the DC power to the wiring box. Do not startup the PV Inverter while the fuse cover is removed. The dummy fuses must be kept within fuse holder if there is no protection fuses are planned to be installed. CAUTION Each port (terminal) of the multi-string DC input terminal is only able to connect with a maximum 20A connection.

9. Maintenance 9.1 External cooling fan replacement For PV240 and PV250 models, there is no cooling fan designed for the external housing, but an internal fan designed within PV inverter for the thermal management. Therefore, “FAN Lock” is the only failures message that user will retrieve from the LCD if the operation of internal cooling fan has failed. If this situation happens, please contact the Eaton service personnel for further instructions.
If the cooling fan is dirty, a vacuum cleaner can be used to clean from the top of the PV Inverter. If the cleaning procedure does not fixed the problem, service personnel can determine the status of the cooling fan and make a replacement. The following procedures described how to change the cooling fan, therefore, please read and understand all procedures before doing so. A) Switch off the DC/AC disconnect switch and wait for three minutes to discharge the stored energy for the PV inverter. Figure 9.1.
C) After cooling fan is already lifted out, disconnect the power cable of the cooling fan as shown in Figure 9.1.3. Figure 9.1.3: Disconnects the power cables of the cooling fan D) Install a new cooling fan by connecting its power cable to PV Inverter. Then re-tighten the 4 screws at the top cover. E) Switch on the DC/AC disconnect in order to complete the fan replacement procedure. Eaton Corporation Page 61 Ver 1.
9.2 Cleaning the LCD Display If the screen of the LCD display and the LED indicators are dusty and not readable, please use a piece of damp cloth to clean the surface. 9.3 Install or Replace the DC/AC fuse Insulation Protection An insulation glove should be worn during the configuring and replacing the fuse or installing the components.
