Page 5: Safety Instructions
Safety instructions Risk of Electric Shock 1. Do not remove the casing. Inverter contains no user serviceable parts. Refer servicing to qualified service personnel. 2. When a photovoltaic panel is exposed to light, it generates a DC voltage. When connected to this equipment, a photovoltaic panel will charge the DC link capacitors. - Page 6 Hot surfaces Although designed to meet all safety requirements, some parts and surfaces of Inverter are still hot during operation. To reduce the risk of injury, do not touch the heat sink at the back of the PV-Inverter or nearby surfaces while Inverter is operating.

Page 12: Mounting Inverter To The Wall
Mounting Inverter to the wall Select a wall or solid vertical surface that can support the PV-Inverter. Inverter requires adequate cooling space. Allow at least 20cm space above and below the inverter. Using the mounting frame as a template, drill 4 holes as illustrated in the following figures. - Page 13 Hang the inverter on the mounting frame Check the installation conditions a) Do not install the PV-Inverter on a slanted surface Edition 1.6E, 2010/06...

Page 15: Connecting To The Grid (Ac Utility)
Connecting to the grid (AC utility) Measure grid (utility) voltage and frequency. It should be 230VAC (or 220VAC), 50/60Hz, and single phase. Open the breaker or fuse between PV-Inverter and utility. For Inverter, connect AC wires as follows: Insert utility wires through cable gland. Connect wires according to polarities indicated on terminal block. -

Page 18: System Diagram
PV panel PV Panel: Provide DC power to inverter. EATON ETN1000 / ETN2000 PV Inverter converts DC (Direct Current) power from PV panel(s) to AC (Alternating Current) power. Because Inverter is grid-connected it controls the current amplitude according to the PV Panel power supply. -
Page 19: Operating Your Pv-Inverter
5. Operating Your PV-Inverter Modes of operation There are 3 different modes of operation. 1. Normal mode: In this mode, Inverter works normally. Whenever the supplied power from PV panel is sufficient (voltage>150VDC), Inverter converts power to the grid as generated by the PV panel. If the power is insufficient, (voltage<100VDC) Inverter enters a “waiting”... -
Page 20: Front Panel Arrangement
Front Panel arrangement Function Key LCD (Liquid Crystal Display) Power-on LED Fault LED There are 2 LED’s on Inverter, one is green and the other is red. Normally, only the green LED switches on during operation. Their indicated status is explained as follows: Power on (green LED): It lights to indicate that Inverter is running. -
Page 21: Front Panel
Front Panel Operating Inverter is quite easy. During normal operation, Inverter runs automatically. However, to achieve maximum conversion efficiency of Inverter, please read through the following information: Automatic ON-OFF: Inverter starts up automatically when DC-power from the PV panel is sufficient. Once the PV-Inverter starts it enters one of the following 3 states: Standby: The PV string can only provide just enough voltage to minimum requirements of the controller. - Page 22 Repeatedly press the function key until the desired display is reached. Release the key and press again for more than 2 second until you see “Lock”, release the key; the information remains on the display. To change the display again, please press the key as indicated in above section 3.
