1. Introduction
This hybrid PV inverter can provide power to connected loads by utilizing PV power, utility 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 solar modules (solar panels), battery, and the utility. When MPP input voltage of PV
modules is within acceptable range (see specification for the details), this inverter is able to generate
power to feed the grid (utility) and charge battery. This inverter is only compatible with PV module
types of single crystalline and poly crystalline. Do not connect any PV array types other than these
two types of PV modules to the inverter. Do not connect the positive or negative terminal of the
solar panel to the ground. See Figure 1 for a simple diagram of a typical solar system with this hybrid
inverter.
Note: To conform to the EEG standard, every inverter sold to German area is not allowed to charge
battery from Utility. The relevant function is automatically disabled via the software.

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-
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 so heavy that it should be lifted by at least two persons.
CAUTION! Before attempting any maintenance or cleaning or working on any circuits connected to
the inverter, disconnecting AC, DC and battery power from the inverter can reduce the risk of electric
shock. Merely turning off controls will not reduce this risk because internal capacitors can remain
charged for 5 minutes after disconnecting all sources of power.
CAUTION! Do not disassemble this inverter by yourself. It contains no user-serviceable parts.
Attempt to service this inverter by yourself may cause electric shock or fire and will void the warranty
from the manufacturer.
CAUTION! To avoid fire and electric shock, make sure that existing wiring is in good condition and
that the wire is not undersized. Do not operate the damaged Inverter or substandard wiring.

6. Grid (Utility) Connection
6-1. Preparation
Before connecting to AC utility, please install a separate AC circuit breaker between surge
protection device (SPD) and AC utility. This will ensure the inverter can be securely disconnected
during maintenance and fully protected from over current of AC input.
NOTE1: Although this inverter is equipped with 250Vac/40A fuse, it’s still necessary to install a
separate circuit breaker for safety consideration. Please use 250Vac/40A circuit breaker between
surge protection device (SPD) and AC utility.
NOTE2: The overvoltage category of the AC input is III. It should be connected to the power
distribution.
WARNING! For safety and efficiency, it's very important to use appropriate cables for grid (utility)
connection. To reduce risk of injury, please use the proper cable size recommended below.

6-2. Connecting to the AC Utility
Step 1: Check the grid voltage and frequency with an AC voltmeter to see if it’s same as the
“Vac” value on the product label.
Step 2: Turn off the circuit breaker.
Step 3: Remove insulation sleeve 10 mm from three
conductors and shorten phase L and neutral
conductor N for 3 mm. Refer to chart 1.
Step 4: Connect wires according to the polarities indicating on terminal block. Be sure to connect
PE protective conductor (G) first.

between inverter and PV modules.
NOTE1: Please use 600Vdc/30A circuit breaker.
NOTE2: The overvoltage category of the PV input is II.
Please follow the steps below to implement PV module connection:
Step 1: Check the input voltage of PV array modules. The acceptable input voltage of the inverter
is 250Vdc-450Vdc (with rated load). This system is applied with two strings of PV array. Please
make sure that the maximum current load of each PV input connector is 13A.
Step 2: Disconnect the circuit breaker and switch off the DC switch.
Step 3: Assemble provided PV connectors with PV modules by the following steps.
Components for PV connectors and Tools:
Female connector housing
Female terminal
Male connector housing
Male terminal
Crimping tool and spanner
Prepare the cable and follow the connector assembly process:
Strip one cable 8 mm on both end sides and be careful NOT to nick
conductors.
Insert striped cable into female terminal and crimp female terminal as
shown below.
Insert assembled cable into female connector housing as shown below.
CAUTION: Exceeding the maximum input voltage can destroy the unit!! Check the
system before wire connection.
WARNING: Because this inverter is non-isolated, only three types of PV modules are
acceptable: single crystalline and poly crystalline with class A-rated and CIGS
modules.
To avoid any malfunction, do not connect any PV modules with possible current
leakage to the inverter. For example, grounded PV modules will cause current leakage
to the inverter. When using CIGS modules, please be sure NO grounding.
CAUTION: It’s requested to use PV junction box with surge protection. Otherwise, it
will cause damage on inverter when lightning occurs on PV modules.

Insert striped cable into male terminal and crimp male terminal as shown below.
Insert assembled cable into male connector housing as shown below.
Then, use spanner to screw pressure dome tightly to female connector and male connector as
shown below.
Step 4: Check the correctness of the polarity of connection cable on PV modules and PV input
connectors. Then, connect positive pole (+) of connection cable to positive pole (+) of PV input
connector. Connect negative pole (-) of connection cable to negative pole (-) of PV input connector.
WARNING! For safety and efficiency, it's very important to use appropriate cables for PV module
connection. To reduce risk of injury, please use the proper cable size as recommended below.
