Preparation

Before connecting all wirings, please take off bottom cover by removing two screws as shown below.

Diagram Description: An illustration shows the bottom of the inverter with two screws indicated for removal to access internal wiring.

Mounting the Unit

Consider the following points before selecting where to install:

• Do not mount the inverter on flammable construction materials.
• Mount on a solid surface
• Install this inverter at eye level in order to allow the LCD display to be read at all times.
• The ambient temperature should be between -10°C and 55°C to ensure optimal operation.
• The recommended installation position is to be adhered to the wall vertically.

Be sure to keep other objects and surfaces as shown in the right diagram to guarantee sufficient heat dissipation and to have enough space for removing wires.

Mounting Diagram Description:

A diagram shows the side view of the inverter mounted on a wall. It indicates recommended clearances of 50cm on the sides and 20cm above and below for heat dissipation and wire access. It also shows a vertical mounting orientation and suggests mounting on concrete or non-combustible surfaces.

INSTALLATION - Wiring

Battery Connection

CAUTION: For safety operation and regulation compliance, it's requested to install a separate DC over-current protector or disconnect device between battery and inverter. It may not be requested to have a disconnect device in some applications, however, it's still requested to have over-current protection installed. Please refer to typical amperage in below table as required fuse or breaker size.

WARNING! All wiring must be performed by a qualified personnel.

WARNING! It's very important for system safety and efficient operation to use appropriate cable for battery connection. To reduce risk of injury, please use the proper recommended cable.

Recommended battery cable and terminal size:

Please follow below steps to implement battery connection:

1. Assemble battery ring terminal based on recommended battery cable and terminal size.
2. The 1KW model supports only 12VDC systems. The battery string connection is shown in the chart below. For 1KW models, you are advised to connect a battery with a capacity of at least 100Ah.

Battery Connection Diagram Description:

Diagrams show how to connect batteries for 1KW and 2-3KW models. For the 1KW model, two 12V batteries are shown in series. For the 2-3KW models, two sets of two 12V batteries are shown in series, indicating parallel connection of battery banks.

WARNING: Shock Hazard

Installation must be performed with care due to high battery voltage in series.

CAUTION!! Do not place anything between the flat part of the inverter terminal and the. Otherwise, overheating may occur.

CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals are connected tightly.

CAUTION!! Before making the final DC connection or closing DC breaker/disconnector, be sure positive (+) must be connected to positive (+) and negative (-) must be connected to negative(-).

AC Input/Output Connection

CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between inverter and AC input power source. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 10A for 1KW.

CAUTION!! There are two terminal blocks with "IN" and "OUT" markings. Please do NOT mis-connect input and output connectors.

WARNING! All wiring must be performed by a qualified personnel.

WARNING! It's very important for system safety and efficient operation to use appropriate cable for AC input connection. To reduce risk of injury, please use the proper recommended cable size as below.

Suggested cable requirement for AC wires:

Please follow below steps to implement AC input/output connection:

1. Before making AC input/output connection, be sure to open DC protector or disconnector first.
2. Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3 mm.
3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws. Be sure to connect PE protective conductor [Ground Symbol] first.

AC Wiring Diagram Description:

Diagrams illustrate the connection of AC input and output wires to the terminal blocks. It shows the correct polarity for Ground (yellow-green), Line (brown or black), and Neutral (blue) wires for both AC input and AC output. The PE protective conductor is shown connected first.

CAUTION: Important

Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause utility short-circuited when these inverters are worked in parallel operation.

CAUTION: Appliances such as air conditioner are required at least 2~3 minutes to restart because it's required to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a short time, it will cause damage to your least 2~3 connected appliances. To prevent this kind of damage, please check manufacturer of air conditioner if it's equipped with time-delay function before installation. Otherwise, this inverter/charger will trig overload fault and cut off output to protect your appliance but sometimes it still causes internal damage to the air conditioner.

PV Connection

CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter and PV modules.

WARNING! All wiring must be performed by qualified personnel.

WARNING! It is 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.

PV Module Selection:

When selecting proper PV modules, please be sure to consider below parameters:

1. Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter.
2. Max. power voltage (Vmp) should be during PV array MPPT voltage range.

Solar Charging Mode Table:

Please follow below steps to implement PV module connection:

1. Remove insulation sleeve 10 mm for positive and negative conductors.
2. 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.

PV Connection Diagram Description:

Diagrams show the connection of PV module cables to the inverter's PV input terminals. It emphasizes correct polarity for positive (+) and negative (-) conductors.

1. Turbo is enabled by default. To disable Turbo, you can set it in the Settings or APP.
2. The Turbo mode is disabled in the following three scenarios: (1) The mains is connected and in mains mode (2) The mains is set to UPS mode (3) When the Turbo mode is set to off
3. Turbo mode is more suitable for heating and motor equipment, but not for all electrical appliances, some electrical appliances equipped with voltage protection (such as precision instruments, etc.) do not apply to Turbo mode. To confirm whether the device can use the Turbo mode, refer to the actual test.
