Radiation may cause damage to health.
• Do not stay at a place less than 20cm away from the inverter for a
long time.
Ground the PV generator.
• Comply with the local requirements for grounding the PV modules
and the PV generator.
• It is recommended that generator frames and other conductive
surfaces be connected in a manner that ensures continuous
conduction and grounding for optimum protection of the system
and personnel.
Make sure the input DC voltage is less than the maximum value. Over-
voltage may cause permanent damage to the inverter or other losses,
which will not be covered by the warranty!
Before attempting any maintenance, cleaning or working on any circuits
connected to inverter, authorized service personnel must disconnect
both AC and DC power from inverter.
CAUTION
Danger of burns
• When the product is working, the upper of the enclosure and the
enclosure body may become hot.
• During operation, only the touch screen needs to be operated.

WARNING
WARNING
• It is recommended to use only accessories that are compatible with
the inverter, otherwise it may lead to the risk of fire, electric shock or
personal injury.
• Make sure the existing wiring is in good condition, and the wires are
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 service. Unauthorized repairs may result in a risk of electric shock
or fire and will void your warranty, and will void the warranty.
• Keep away from flammable, explosive materials to avoid fire disaster.
• The installation location should be away from humid or corrosive
substance.
• Authorized service personnel must use insulated tools when installing
or working with this equipment.
• PV modules should have IEC 61730 Class A rating.
• Do not 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 when the MAINS , battery and PV supply has been
disconnected.
• Hazardous voltages may remain present for up to 5 minutes after
disconnection.

01 Safety Precautions
1.1.1 Install surge protection devices (SPDs) for PV
• CAUTION-The energy stored in the capacitor is a shock hazard, do
not operate the inverter, coupler, power cable, battery cable, PV cable
or PV generator while energized. After turning off the PV, battery and
power supply, always wait 5 minutes to allow the intermediate circuit
capacitors to discharge before unplugging the DC, battery and power
coupler.
• When accessing the internal circuit of inverter, it is very important
to wait 5 minutes before operating the power circuit or demounting
the electrolyte capacitors inside the device. Do not open the device
beforehand since the capacitors require time sufficiently discharge!
• Measure the voltage between terminals UDC+ and UDC- with a multi-
meter(impedance at least 1Mohm) to ensure that the device is
discharged ( <35VDC ) before starting to work inside the device.
• 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
• Over-voltage protection with surge arresters should be provided
when installing PV power generation system.
• The grid connected inverter does not have SPDs installed on both
PV input side and MAINS side.

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
consumer’s cutout), located between the inverter and the meter/
distribution system; SPD (test impulse D1) for signal in according l to
EN 61632-1.
• 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.
The islanding effect is a special phenomenon where a grid-connected PV
system still delivers power to the nearby grid when voltage losses occur in
the power system. This can be dangerous for maintenance personnel and

prevent the islanding effect.
• 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 about 700nf.
• Incorrect grounding can cause physical injury, death or equipment
malfunction and increase electromagnetic.
• Make sure that grounding conductor is adequately sized as required
by safety regulations.
• Do not connect the ground terminals of the unit in series in case
of a multiple installation. This product can cause current with a DC
component, Where a residual current operated protective (RCD) or
monitoring (RCM) device is used for protection in case of direct or
indirect contact, only an RCD or RCM of type B is allowed on the

Revo hybrid Series inverter should be worked with high voltage battery, for
the specific parameters such as battery type, nominal voltage and nominal
capacity etc., please refer to section 4.
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 off load connected to the batteries before dismantling battery
