1. Introduction
This hybrid PV inverter can provide power to connected oads by uti izing PV power,
uti ity power and battery power.
Figure 1: Basic hybrid PV System Overview
Depending on different power situations, this hybrid inverter is designed to generate
continuous power from PV so ar modu es (so ar pane s), battery, and the uti ity. When MPP
input vo tage of PV modu es is within acceptab e range (see specification for the detai s),
this inverter is ab e to generate power to feed the grid (uti ity) and charge battery. This
inverter is on y compatib e with PV modu e types of sing e crysta ine and po y crysta ine.
Do not connect any PV array types other than these two types of PV modu es to the
inverter. Do not connect the positive or negative termina of the so ar pane to the ground.
See Figure 1 for a simp e diagram of a typica so ar system with this hybrid inverter.
Note: By fo owing the EEG standard, every inverter so d to German areas is not a owed
to charge battery from Uti ity. The re evant function is initia y disab ed by the
software.

be performed by qua ified personne on y.
General Precaution:
WARNING! Before insta ing and using this inverter, read a instructions and cautionary
markings on the inverter and a appropriate sections of this guide.
WARNING! Norma y grounded conductors may be ungrounded and energized when a
ground fau t is indicated.
WARNING! This inverter is heavy. It shou d be ifted by at east two persons.
CAUTION! Authorized service personne shou d reduce the risk of e ectrica shock by
disconnecting AC, DC and battery power from the inverter before attempting any
maintenance, c eaning or working on any circuits connected to the inverter. Turning off
contro s wi not reduce this risk. Interna capacitors can remain charging for 5 minutes
after disconnecting a sources of power.
CAUTION! Do not disassemb e this inverter by yourse f. It contains no user-serviceab e
parts. Attempting to service this inverter by yourse f may cause a risk of e ectrica shock
or fire and wi void the warranty from the manufacturer.
CAUTION! To avoid a risk of fire and e ectric 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.
Conventions used:
WARNING! Warnings identify conditions or practices that cou d resu t in persona
injury;
CAUTION! Caution identify conditions or practices that cou d resu t in damaged to the
unit or other connected equipment.

CAUTION! Under environment of high temperature, the cover of this inverter cou d be
hot enough to cause skin burns if accidenta y touched. Ensure that this inverter is away
from norma traffic f ow.
CAUTION! Use on y recommended accessories from insta er. Otherwise, not-qua ified
too s may cause a risk of fire, e ectric shock, or injury to persons.
CAUTION! To reduce risk of fire hazard, do not cover or obstruct the coo ing fan.
CAUTION! Do not operate the Inverter if it receives a sharp b ow, drops, or otherwise is
damaged in any way. If the Inverter is damaged, p ease ca for an RMA (Return Materia
Authorization).

4. Installation
4-1. Selecting Mounting Location
Consider the fo owing points before se ecting where to insta :
Do not mount the inverter on f ammab e construction materia s.
Mount on a so id surface
This inverter can make noises which may be a nuisance in a iving area during
operation.
Insta this inverter at eye eve to faci itate the readabi ity of LCD disp ay at a
times.
For proper air circu ation to dissipate heat, ensure a c earance of approx. 20 cm to
the side and approx. 50 cm above and be ow the unit.
Dusty conditions on the unit may impair the performance of this inverter.
The ambient temperature shou d be between 0°C and 40°C and re ative humidity
shou d be between 5% and 85% to ensure optima operation.
The recommended insta ation position is to be adhered to the vertica .
For proper operation of this inverter, p ease use appropriate cab es for grid
connection.
The po ution degree of the inverter is PD2. Se ect an appropriate mounting
ocation. Insta the so ar inverter in a protected area where is dry, free of
excessive dust and has adequate air f ow. Do NOT operate it where the
temperature and humidity is beyond the specific imits. (P ease check the specs for
the imitations.)
Insta ation position sha not prevent access to the disconnection means.
This inverter is designed with IP20 standard and it’s for indoor app ications on y.
Regu ar y c ean the fan fi ter.

5. Grid (Utility) Connection
5-1. Preparation
Before connecting to AC uti ity, p ease insta a separate AC circuit breaker between
inverter and AC uti ity. This wi ensure the inverter can be secure y disconnected during
maintenance and fu y protected from over current of AC input.
NOTE1: A though this inverter is equipped with 250VAC/40A fuse, it’s sti necessary to
insta a separate circuit breaker for safety consideration. P ease use
250VAC/40A circuit breaker between inverter and AC uti ity.
NOTE2: The overvo tage category of the AC input is III. It shou d be connected to the
power distribution.
WARNING! It's very important for system safety and efficient operation to use
appropriate cab e for grid (uti ity) connection. To reduce risk of injury, p ease
use the proper size of cab e recommended be ow.
