1. SAFETY
This device should only be used in accordance with the instructions within this manual and in
compliance with local, regional, and national laws and regulations. Only allow this device to be installed,
operated, maintained, and repaired by other person(s) who have read and understood this manual.
Ensure the manual is included with this device should it be passed to a third party.
DO NOT allow minors, untrained personnel, or person(s) suering from a physical or mental impairment
that would aect their ability to follow this manual, install, maintain or repair this device.
Any untrained personnel who might get near this device while it is in operation MUST be informed that it
is dangerous and instructed carefully on how to avoid injury.
1.1. General Safety
1.2. Symbols
WARNING This symbol indicates information that if ignored, could result in personal
injury or even death due to incorrect handling.
CAUTION This symbol indicates information that if ignored, could result in personal
injury or physical damage due to incorrect handling.
PLEASE NOTE Indicates information that is considered important, but not hazard-related.

HYBRID INVERTER | Installer Manual6
1.3. Safety Instructions
Be sure to read this manual thoroughly before installation.
Do not attempt to install the inverter by yourself. Installation work must be carried out in compliance
with national wiring standards and by suitably qualied personnel only. Do not turn on the power until all
installation work is complete.
Do not disassemble the inverter. If you need repair or maintenance, contact a professional service
centre.
Always use an individual power supply line protected by a circuit breaker and operating on all wires with
a distance between contacts of at least 3mm for this unit.
The unit must be correctly grounded, and the supply line must be equipped with a suitable breaker and
RCD to protect people.
Disconnect all wires/cables before performing any maintenance or cleaning to reduce the risk of
electrical shock.
The unit is not explosion-proof, so it should not be installed in an explosive atmosphere.
Never touch electrical components immediately after the power supply has been turned o since the
system can still have residual energy, so an electric shock may occur. Therefore, after turning o the
power, always wait 5 minutes before touching electrical components.
This unit contains no user-serviceable parts. Always consult an authorised contractor for repairs.
1.4. Disposal
DO NOT dispose this product with domestic waste!

4. INSTALLATION
4.1. Parts List
Check the equipment before installation. Please make sure nothing is damaged in the package. You should
have received the items in the following package:

HYBRID INVERTER | Installer Manual15
4.2. Selecting the Mounting Area
DO NOT install the inverter in the following areas:
Areas with high salt content, such as the marine environment. It will deteriorate the metal parts and
possibly lead to water/dampness penetrating the unit.
Areas lled with mineral oil or containing splashed oil or steam, such as those found in kitchens. It will
deteriorate plastic parts of the unit, causing those parts to fail or allowing water/damp to penetrate the
unit.
Areas that generate substances that adversely aect the equipment, such as sulphuric gas, chlorine gas,
acid, or alkali. These can cause the copper pipes and brazed joints to corrode and fail to conduct
electricity reliably.
Areas that can cause combustible gas to leak, which contains suspended carbon-bre or ammable
dust, or volatile inammable such as paint thinner or gasoline.
Areas where there may be gas leaks and where gas may settle around the unit as this is a re risk.
Areas where animals may urinate on the unit or ammonia may be generated.
High altitude areas (over 4000 metres above sea level).
Environments where precipitation or humidity is above 95%
Areas where the air circulation is too low.
4.3. System Diagram
ALSO CONSIDER:
Installing the indoor unit, outdoor unit, power supply cable, transmission cable, and remote control cable
at least 1 metre away from any television or radio receiver. This will prevent TV reception interference or
radio noise. This will prevent radio signal interference from external units that might interfere with the
Wi-Fi or GSM monitoring.
If children under 10 years old may approach the unit, take preventive measures so they cannot reach
and touch the unit.

HYBRID INVERTER | Installer Manual16
Install the indoor unit on the wall where the oor height is higher than 1600mm.
For proper heat dissipation, allow a clearance of approximately 500mm to the side, 500mm above and
below the unit, and 1000mm to the front of the unit.
≥500mm
≥500mm
4.4. Mounting the Inverter
Select installation locations that are adequate to support the weight of the converter.
Install this inverter at eye level to allow the LCD to be read anytime.
An appropriate ambient temperature is between -25 ~ 60°C to ensure optimal operation.
Be sure to keep other objects and surfaces, as shown in the gure to guarantee sucient heat
dissipation and have enough space to remove wires.
For proper air circulation to dissipate heat, allow a clearance of approximately 50cm to the side.
WARNING
Risk of injury (Heavy Object).
Remember that this inverter is heavy so users must be careful in handling the unit during installation
especially when mounting or removing from a wall.

4.5. Battery Connection
For safe operation and compliance, a separate DC over-current protector or disconnect device is required
between the battery and the inverter. Switching devices may not be required in some applications, but
over-current protectors are still required. Refer to the typical amperage in the table below for the required
fuse or circuit breaker size.

HYBRID INVERTER | Installer Manual18
Please follow the below steps to implement battery connection:
Please choose a suitable battery cable with the correct connector which can well t into the battery
terminals.
Use a suitable screwdriver to unscrew the bolts and t the battery connectors in, then fasten the bolt
with the screwdriver, ensuring the bolts are lightened with a torque of 5.2 N.m in a clockwise direction.
Make sure the polarity at both the battery and inverter is correctly connected.
In case of children touching or insects, go into the inverter. Please make sure the inverter connector is
fastened to a waterproof position by twisting it clockwise.

CAUTION
Reverse Polarity.
Before making the nal DC connection or closing DC breaker/disconnect, be sure positive (+) must
be connected to the positive (+) and negative (-) must be connected to the negative (-). A reverse
polarity connection on the battery will damage the inverter.
CAUTION
All wiring/connecting must be performed by qualied personnel. Before making the nal DC
connection or closing the DC Breaker/disconnection device, ensure the inverter unit is wired
correctly. A reverse-polarity connection on the battery will damage the inverter.

4.6. Connecting a Lithium Battery
When connecting a Lithium battery, follow the connection steps below and check ‘Setting up a Lithium
Battery’ to connect with an inverter.
1. Connect the correct cable diameter following the battery manufacture specications and recommended
safety devices.
2. Connect a communication cable from the batteries to the inverter in compliance with the battery
manufacturer's guidelines. The cables have two ends, one to be specically connected to the BMS and
another to be connected to the inverter, do not misconnect them.
3. Connect the power and communication cables to the inverter correctly.

HYBRID INVERTER | Installer Manual20
PLEASE NOTE
When connecting more than one battery, ensure they are set in the conguration of ‘master and
slave’.
4.7. Battery Temperature Sensor Connection
Without a remote temperature sensor, lead-acid batteries may undercharge or overcharge depending on
the ambient temperature of the installation environment. This may result in a re hazard.
PLEASE NOTE
Depending on the battery type, the inverter should be capable of controlling the batteries BMS.
Therefore, you need to set the protocol of the BMS on both the battery and the inverter.
When using more than one battery, the rst battery will be the master, and the other batteries will
be the slaves. Please, check the battery manufacturer's specications for proper operation.
To verify if the battery is communicating, access the Li BMS menu as detailed in the section ‘Setting
Up a Lithium Battery’ and check whether the values are realistic. It is important that the charge and
discharge limits in that page match the numbers expected for the number of batteries physically
connected.
