1.3. Symbols Used
The following types of safety instructions and general information appear in this
document as described below:

2
Caution!
Danger of burn injuries due to hot enclosure parts!
During operation, the upper lid of the enclosure and the enclosure body
may become hot.
Only touch the lower enclosure lid during operation
Caution!
Possible damage to health as a result of the effects of radiation!
Do not stay closer than 20 cm to inverter for any length of time.
Note!
Grounding the PV generator
Comply with the local requirements for grounding the PV modules and
the PV generator. It is recommends connecting the generator frame and
other electrically conductive surfaces in a manner which ensures
continuous conduction and ground these in order to have optimal
protection of system and persons.
Warning !
Ensure input DC voltage ≤Max. DC voltage. Over voltage may cause
permanent damage to inverter or other losses, which will not be included
in warranty!
2. Safety
2.1. Important Safety Instructions
Danger!
Danger to life due to high voltages in the inverter!
All work must be carried out by qualified electrician.
The appliance is not to be used by children or persons with reduced
physical sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction.
Children should be supervised to ensure that they do not play with the
appliance.

3
Warning !
Do not operate the inverter when the device is running .
Warning !
Risk of electric shock!
Please keep the user manual properly. When operating equipment, in addition to
following the general precautions in this document, follow the specific safety
instructions. We will not be liable for any consequence caused by the violation of
the safety operation regulations and design, production, and usage standards.
Accessories only together with the inverter shipment are recommended here.
Otherwise may result in a risk of fire, electric shock, or injury to person.
Make sure that existing wiring is in good condition and that wire is not undersized.
Do not disassemble any parts of inverter which are not mentioned in installation
guide. It contains no user-serviceable parts. See Warranty for instructions on
obtaining service. Attempting to service the inverter yourself may result in a risk of
electric shock or fire and will void your warranty.
Keep away from flammable, explosive materials to avoid fire disaster.
The installation place should be away from humid or corrosive substance.
Authorized service personnel must use insulated tools when installing or working
with this equipment.
Never touch either the positive or negative pole of PV connecting device. Strictly
prohibit touching both of them at the same time.
The unit contains capacitors that remain charged to a potentially lethal voltage after
the MAINS, battery and PV supply has been disconnected.
Hazardous voltage will present for up to 5 minutes after disconnection from power
supply.
CAUTION-RISK of electric shock from energy stored in capacitor. Never operate on
the inverter couplers, the MAINS cables, Battery cables, PV cables or the PV
generator when power is applied. After switching off the PV, battery and Mains,
always wait for 5 minutes to let the intermediate circuit capacitors discharge before
unplugging DC, battery in plug and MAINS couplers.
When accessing the internal circuit of inverter, it is very important to wait 5 minutes
Warning !
Authorized service personnel must disconnect both AC and DC power
from inverter before attempting any maintenance or cleaning or working
on any circuits connected to inverter.

4
Warning !
Over-voltage protection with surge arresters should be provided
when the PV power system is installed.
The grid connected inverter is not fitted with SPDs in both PV input
side and MAINS side.
before operating the power circuit or demounting the electrolyte capacitors inside
the device. Do not open the device before hand since the capacitors require time
sufficiently discharge!
Surge protection devices (SPDs) for PV installation.
Lightning will cause a damage either from a direct strike or from surges due to a
nearby strike.
Induced surges are the most likely cause of lightning damage in majority or
installations, especially in rural areas where electricity is usually provided by long
overhead lines. Surge may be included on both the PV array conduction and the AC
cables leading to the building.
Specialists in lightning protection should be consulted during the end use application.
Using appropriate external lightning protection, the effect of a direct lightning strike
into a building can be mitigated in a controlled way, and the lightning current can
be discharged into the ground.
Installation of SPDs to protect the inverter against mechanical damage and
excessive stress include a surge arrester in case of a building with external lightning
protection system (LPS) when separation distance is kept.
To protect the DC system, surge suppression device (SPD type2) should be fitted at
the inverter end of the DC cabling and at the array located between the inverter
and the PV generator, if the voltage protection level (VP) of the surge arresters is
greater than 1100V, an additional SPD type 3 required for surge protection for
electrical devices.
To protect the AC system, surge suppression devices (SPD type2) should be fitted at
the main incoming point of AC supply (at the consumers cutout), located between
the inverter and the meter/distribution system;
All DC cables should be installed to provide as short a run as possible, and positive
and negative cables of the string or main DC supply should be bundled together.
Avoiding the creation of loops in the system.
Spark gap devices are not suitable to be used in DC circuits once conducting, they
won’t stop conducting until the voltage across their terminals is typically more than
30 volts.

5
Warning !
High leakage current!
Earth connection essential before connecting supply.
 Anti-Islanding Effect
Islanding effect is a special phenomenon that grid-connected PV system still supply
power to the nearby grid when the voltage loss is happened in the power system. It is
dangerous for maintenance personnel and the public.
Hybrid series inverter provide Active Frequency Drift(AFD) to prevent islanding
effect.
 PE Connection and Leakage Current
The end-use application shall monitor the protective conductor by residual current
operated protective device (RCD) with rated fault current Ifn≤240mA which
automatically disconnects the device in case of a fault.
The device is intended to connect to a PV generator with a capacitance limit of
approx 700nf.
Incorrect grounding can cause physical injury, death or equipment malfunction and
increase electromagnetic.
 Battery Safety Instructions
Hybrid Series inverter should be worked with low voltage battery, for the specific
parameters such as battery type, nominal voltage and nominal capacity etc., please
refer to section 4.1.
As accumulator batteries may contain potential electric shock and short-circuit
current danger, to avoid accidents that might be thus resulted, the following warnings
should be observed during battery replacement:
1: Do not wear watches, rings or similar metallic items.
2: Use insulated tools.
3: Put on rubber shoes and gloves.
4: Do not place metallic tools and similar metallic parts on the batteries.
5: Switch offload connected to the batteries before dismantling battery connection
terminals.
6: Only personal with proper expertise can carry out the maintenance of
accumulator batteries.

Note!
Please control the home loads, and make sure it’s within the “BACK-UP
output rating” under BACK-UP mode, otherwise the inverter will shut down
with an “overload fault” warning.
Please confirm with the mains grid operator whether there is any special
regulations for grid connection.
3. Introduction
3.1. Basic features
Hybrid Series is a high-quality inverter which can convert solar energy to AC energy
and store energy into battery.
The inverter can be used to optimize self-consumption, store in the battery for
future use or feed in to public grid. Work mode depends on PV energy and user’s
preference. It can provide power for emergency use during the grid lost by using the
energy from battery and inverter (generated from PV).
3.2. System Diagram
Hybrid Series is designed with two BACK-UP versions for customer to choose based
on the local rules.The applies to the wiring rules that requires Neutral line of alternative
supply must NOT be isolated or switched .
