1. Introduction
This hybrid PV inverter can provide power to connected loads by utilizing PV
power, utility power and battery power.
Battery
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: By following the EEG standard, every inverter sold to German area is not
allowed to charge battery from Utility. The relevant function is automatically
disabled by 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 heavy. It should be lifted by at least two persons.
CAUTION! Authorized service personnel should reduce the risk of electrical
shock by disconnecting AC, DC and battery 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, the cover 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 cooling fan.
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, please
call for an RMA (Return Material Authorization).
CAUTION! AC breaker, DC switch and Battery circuit breaker are used as
disconnect devices and these disconnect devices shall be easily accessible.

7. PV Module (DC) Connection
NOTE1: The overvoltage category of the PV input is Ⅱ.
NOTE2: Please use 1000VDC/35A circuit breaker.
Please follow below steps to implement PV module connection:
Step 1: Check the input voltage of PV array modules. The acceptable input
voltage of the inverter is 350VDC - 1000VDC. This system is only applied with
three strings of PV array. Please make sure that the maximum current load of
each PV input connector is 26A.
Step 2: Disconnect the circuit breaker and switch off the DC switch.
Step 3: Assemble provided PV connectors with PV modules by the following
below steps.
Components for PV connectors and Tools:
Female connector housing
Female terminal
Male connector housing
CAUTION: Exceeding the maximum input voltage can destroy the unit!! Check the
system before wire connection.
WARNING: Because this inverter is non-isolated, only two types of PV modules are
acceptable: single crystalline and poly crystalline with class A-rated.
To avoid any malfunction, do not connect any PV modules with possibility of leakage
current to the inverter. For example, grounded PV modules will cause leakage current to
the inverter.
CAUTION: It’s requested to have PV junction box with surge protection. Otherwise, it
will cause inverter damage when lightning occurs on PV modules.

The reference Nut cap locking force is 2.0~2.5Nm.
Step 4: Check correct polarity of connection cable from 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! It's very important for system safety and efficient operation to use
appropriate cable for PV module connection. To reduce risk of injury, please use
the proper recommended cable size as below.
