HYBRID INVERTER | Installer Manual13
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 pos-
sibly 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 elec-
tricity 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.

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 Manual14
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.
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 dissipa-
tion 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.

HYBRID INVERTER | Installer Manual15
Choose the recommended drill head(as shown below) to drill 4 holes on the wall, 52-60mm deep.
Use a proper hammer to t the expansion bolt into the holes.
Carry the inverter and hold it, ensure the hanger aims at the expansion bolt, and x the inverter on the
wall.

HYBRID INVERTER | Installer Manual17
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 con-
nection 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. 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.

4.7. Connecting a Lithium Battery
When connecting a Lithium battery, follow the connection steps below and check ‘Setting up a Lithium Bat-
tery’ 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 manu-
facturer'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 Manual19
PLEASE NOTE
When connecting more than one battery, ensure they are set in the conguration of ‘master and
slave’.
4.8. 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. There-
fore, 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 con-
nected.
