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. Therefore, it is
important that all installing procedures shall be completed by qualified
personnel that are trained to install and operate PV Inverters. Moreover, this
user manual only describes the information that needed for the Eaton grid-tie
PV Inverter and does not cover any installation information relating to other
equipment installed in the PV system. The following safety instruction shall
be followed:
WARNING
It is necessary that only qualified personnel conduct the
installation and operation of the Eaton grid-tie PV Inverter.
Otherwise, risk of damage could occur to the unit or connected
property due to improper installation and/or electrical shock do
due improper actions.
ELECTRICAL SHOCK
Alternating Current (AC) and Direct Current (DC) sources are
terminated in this device. In order to prevent risk of electrical
shock during maintenance or installation, it is necessary to
ensure that all AC and DC terminals are disconnected.
HOT SURFACE
Although inverter is designed to meet international safety
standards, the surface of the inverter can become hot during
operation. Therefore, do not touch the heat sink or peripheral
surfaces during or shortly after operation.
ELECTRICAL SHOCK
Risk of electrical shock from energy stored in capacitors. Do not
remove the cover until three minutes after disconnecting all
sources of supply power and the service shall be done by
qualified personnel.

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.
The following figure shows the general configuration for a PV Inverter a grid

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. Therefore, Eaton grid-tied PV Inverters will not be suitable
with PV modules that are required to have the negative (–) or positive (+)
polarity of the PV module connected to ground. For such application,
please contact the supplier before proceeding.

A. LCD Display
LCD screen displays all measured values and parameters.
B. LED Indicators
There are three indicators used to indicate the operating status.
C. Control Keys
They are three control keys available to switch between each display
menu and configure the settings for the LCD.
D. DC/AC Switch
It is a built-in disconnect switch that is used to disconnect both the DC
input and AC output power from the PV inverter.
E. Night Backlight Button
When the inverter has stopped operating at night, a night backlight
momentary
button provides startup power to the PV inverter in order to
active the LCD screen with LED backlight during the night. Therefore,
user will be able to obtain the operating information in the night.
However, the button should be immediately release pressed.
F. Handling Area
It is a carrying area that is used to lift off PV Inverter. For the lifting, two
people are required due to the size and weight of PV Inverter.
