1. Introduction
1-1. Overview
This PV inverter is designed to convert solar electric (photovoltaic or PV) power into
utility-grade electricity that can be sold to the local power company. This inverter is embedded
with smart MPP tracker to allow the PV inv erter to operate at optimum power output voltage.
Figure 1 Basic PV System Overview
This inverter is only compatible with PV module types of single crystalline and poly crystalline.
And, only Class A-rated PV modules are acceptable to use. Do not connect any sources of
energy other than these two types of PV modules to the inverter. When designing the PV
system, ensure that the values comply with the permitted operating range of all components
at all times. See Figure 1 for a simple diagram of a typical PV system with the Inverter.
1-1. Affecting Factors for Performance of the Inverter
There are a lot of factors to influence the performance of this inverter.
Rating for PV Modules
PV modules are r at ed at ideal f acto ry conditions , such as spec ified illumination (1000 W/m2),
spectrum of the light and temperature (25 °C / 77 °F). This is called the STC (Standard Test
Condition) rating and is the figure that appears on the spec label of PV module. Generally
speaking, only around 60% to 70% of its peak STC-rated output will be produced from your
PV modules due to unpredicted environmental factors.
Temperature and Power Reduction
Environment temperature affects the power output of PV modules. Higher the temperature,
lower the power output of PV module. Comparing with pole-mounted PV module array,
roof-mounted PV module array generates less power due to less air circulation and excess
heat from roof top.

Conventions used:
WARNING! Warnings identify co ndit ions or practices that could result in personal injur y;
CAUTION! Caution identify conditions or practices that could result in damaged to the
unit or other equipment connected.
Important: The inverter will reduce its output generation to protect its electronic circuits
from overheating and any damage under high temper ature environment. For maximum power
output in high temperature, it’s recommended to mount the inverter in a shaded location with
good ventilation.
Angle of the Sun
The angle of the sun in relation to the PV ar ray surf ace—the arr ay orientatio n can dramatic ally
affect the PV arr ay output. The arr ay energy out put will vary depend ing on the time of da y and
time of year as the sun’ s angle in relation to the array changes. Sunlig ht outp ut de creases as
the sun approaches the horizons (such as in winter in Europe) due to the greater atmospheric
air mass it must penetr ate, reducing both the light i ntensity that strikes the arr ay’s surface and
spectrum of the light. In general, you can expect only four to six hours of direct sunlight per
day depending on what part of Europe the inverter is installed.
Partial Shade
Shading on a single PV module of the array will reduce the output power of the entire system.
Such shading can be caused by something as simple as the shadow of a utility wire or tree
branch on part of the array’s surface. This condition, in effect, acts like a weak battery in a
flashlight, reducing the total output, even though the other batteries are good. However, the
output loss is not pr oportionate to shad ing even a tiny bi t of shading w ill reduce t he PV power
to the inverter. The inverter is designed to maximize its power production in all of the above
situations using its proprietary MPPT algorithm.
Other Factors
Other factors to reduce power generation of a solar system are:
Dust or dirt on the modules
Fog or smog
Mismatched PV array modules, with slight inconsistencies in performance from one
module to another.
Inverter efficiency
Wire losses
Utility grid voltage
2. Important Safety Warning
Before using the inverter, please read all instructions and cautionary markings on
the unit and this manual. Store the manual where it can be accessed easily.
This manual is for qualified personnel. The tasks described in this manual may be performed
by qualified personnel only.
General Precaution-
Page 5

WARNING! Before installing and using this inverter, read all instructions and cautionary
markings on the inverter and all appropriate sections of this guide.
WARNING! Normally grounded conductors may be ungrounded and energized when a
ground fault is indicated.
WARNING! This inverter is heavy. It should be lifted by at least two persons.
CAUTION! Authorized service personnel should reduce the risk of electrical shock by
disconnecting both the AC and DC power from the inverter before attempting any
maintenance or cleaning or working on any circuits connected to the inverter. Turning off
controls will not reduce this risk. Internal capacitors can remain charged for 5 minutes after
disconnecting all sources of power.
CAUTION! Do not disassemble this inverter yourself. It contains no user-serviceable parts.
Attempt to service this inverter yourself may cause a risk of electrical shock or fire and will
void the warranty from the manufacturer.
CAUTION! To avoid a risk of fire and electric shock, make sure that existing wiring is in good
condition and that the wire is not undersized. Do not operate the Inverter with damaged or
substandard wiring.
CAUTION! Under high temperature environment, heat sink of this inverter could be hot
enough to cause skin burns if accidentally touched. Ensure that this inverter is away from
normal traffic areas.
CAUTION! Use only recommended accessories from installer. Otherwise, not-qualified tools
may cause a risk of fire, electric shock, or injury to persons.
CAUTION! To reduce risk of fire hazard, do not cover or obstruct the heat sink.
CAUTION! Do not operate the Inverter if it has received a sharp blow, been dropped, or
otherwise damaged in any way. If the Inverter is damaged, called for an RMA (Return Material
Authorization).

4. Installation
4-1. Selecting Mounting Location
Consider the following points before selecting where to install:
Do not mount the inverter on flammable construction materials.
Mount on a solid surface
Although the unit is fitted with UV resistant components, direct exposure to sunlight
may cause a power reduction due to excessive heating.
This inverter can make noises during oper ation which may be perceived as a nuisance in
a living area.
Install this inverter at eye level in order to allow the LCD display to be read at all times.
For proper air circulation to dissipate heat, allow a clearance of approx. 20 cm to the
side and approx. 50 cm above and below the unit.
Dusty conditions on the unit may impair the performance of this inverter.
The ambient temperature should be between -25°C and 60°C to ensure optimal
operation.
The recommended installation position is to be adhered to (vertical).
Unused DC connectors and interfaces must be sealed with sealing plugs to ensure
protection class IP65 for the whole system (inverter & cables).
This inverter is designed with IP65 for outdoor applications with high humidity.

NOTE1: Although this inverter is equipped with a fuse (F1 point on PCB, 3KW: 250VAC/20A;
5KW: 250VAC/30A), it’s still necessary to install a separate circuit breaker for safety
consideration. Please use 250VAC/20A circuit breaker for 3KW and 250VAC/30A circuit
breaker for 5KW.
NOTE2: If you want to add a manual RCMU, it shall be type B.

Then, switch on the AC circuit breakers. After 60 seconds, the system will automatically
connect to the grid. Then:
If inverter icon is in the LCD display like below, commissioning has been successfully.
Or, if
icon flashes, there is insufficient radiation and the inverter is in standby
mode. Wait for sufficient radiation.
Or, if icon flashes, the grid voltage or frequency is beyond acceptable range
and the inverter is in standby mode. Wait for grid voltage or frequency to return to
acceptable range.
Or if
icon flashes, there has been an error. Please check chapter 11 for trouble
