2. Setup and Installation

2.1 Unpacking and Inspection

Before installation, carefully inspect the unit for any damage. The package should contain the inverter unit and a user manual.

2.2 Preparation

Before connecting any wiring, remove the bottom cover by unscrewing the two screws.

2.3 Mounting the Unit

Select an appropriate location for installation based on the following:

• Do not mount on flammable materials.
• Mount on a solid surface.
• Install at eye level for easy LCD display reading.
• Ambient temperature should be between 0°C and 55°C.
• Mount vertically on the wall.
• Ensure sufficient space (20cm sides, 50cm top/bottom) for heat dissipation and wiring access.

WARNING: Suitable for mounting on concrete or other non-combustible surfaces only.

2.4 Battery Connection

CAUTION: Install a separate DC over-current protector or disconnect device between the battery and inverter. All wiring must be performed by qualified personnel.

Use appropriate cable sizes for battery connection. Refer to the table below for recommended cable specifications:

Steps for Battery Connection:

1. Remove 18mm of insulation from positive and negative cables.
2. Connect all battery packs as required.
3. Insert battery cables into the inverter's battery connector, ensuring correct polarity (positive to positive, negative to negative), and tighten bolts to 2-3 Nm.

2.5 AC Input/Output Connection

CAUTION: Install a separate AC breaker between the inverter and the AC input power source. The recommended AC breaker spec is 50A. Do not mis-connect input and output connectors. All wiring must be performed by qualified personnel.

Refer to the table below for recommended cable specifications for AC wires:

Steps for AC Input/Output Connection:

1. Before making connections, ensure the DC protector or disconnector is open.
2. Remove 10mm of insulation for the six conductors. Shorten phase L and neutral conductor N by 3mm.
3. Insert AC input wires into the terminal block according to polarities and tighten screws. Connect the PE protective conductor (yellow-green) first.
4. Insert AC output wires into the terminal block according to polarities and tighten screws. Connect the PE protective conductor (yellow-green) first.
5. Ensure all wires are securely connected.

CAUTION: Appliances like air conditioners require 2-3 minutes to restart. If a power shortage occurs and recovers quickly, it can damage connected appliances. Check if your air conditioner has a time-delay function.

2.6 PV Connection

CAUTION: Install a separate DC circuit breaker between the inverter and PV modules. All wiring must be performed by qualified personnel.

When selecting PV modules, ensure the open circuit voltage (Voc) of PV modules does not exceed the max. PV array open circuit voltage of the inverter (500VDC) and is higher than the min. battery voltage. Refer to the table below for recommended cable specifications:

Steps for PV Module Wire Connection:

1. Remove 10mm of insulation from positive and negative conductors.
2. Check correct polarity of connection cable from PV modules and PV input connectors. Connect positive (+) to positive (+) and negative (-) to negative (-).
3. Ensure the wires are securely connected.

2.7 Lithium Battery Connection (Optional)

If using a lithium battery, ensure it is a compatible model configured for the inverter. The inverter has two connectors for lithium batteries: RS485 port of BMS and power cable.

Steps for Lithium Battery Connection:

1. Assemble battery terminals as per recommended battery cable and terminal size (similar to Lead-acid battery connection).
2. Connect the RS485 port of the battery to the BMS (RS485) communication port of the inverter. Ensure a Pin-to-Pin connection.

Lithium Battery Communication and Setting:

The BMS communication cable facilitates information exchange between the lithium battery and the inverter, allowing the inverter to:

• Re-configure charging voltage, charging current, and battery discharge cut-off voltage based on lithium battery parameters.
• Start or stop charging based on the lithium battery status.

RS485 Port Pin Assignment:

Lithium Battery LCD Setting:

After connecting, complete and confirm the following settings:

1. Select program 05 as 'lithium battery type'.
2. Confirm program 41/42/43/44/45 setting values.

If communication is successful, the LCD will display specific information, including a 'Communication successful icon', 'Max lithium battery charging voltage', 'Max lithium battery charging current', 'Lithium battery discharging is forbidden', 'Lithium battery charging is forbidden', and 'Lithium battery SOC(%)'.

2.8 Final Assembly

After connecting all wirings, replace the bottom cover and secure it with the two screws.

3.4 Battery Equalization

Battery equalization reverses the buildup of negative chemical effects like stratification and removes sulfate crystals, which can reduce battery capacity. It is recommended to equalize the battery periodically.

How to Apply Equalization Function:

1. Enable battery equalization in LCD setting program 33.
2. Apply by setting equalization interval in program 37 or activating immediately in program 39.

When to Equalize:

The controller enters the Equalize stage when the setting equalization interval is reached or immediately activated.

Equalize Charging Time and Timeout:

During equalization, the controller charges the battery until it reaches the equalization voltage, then maintains this voltage. The battery remains in this stage until the set equalized time is reached. If the battery voltage does not reach the equalization point within the timeout, the charge controller will extend the time. If it still doesn't reach the voltage after the timeout, equalization stops, and the system returns to float stage.

3.5 Charging Modes

• Solar Only: Solar energy is the sole charge source, regardless of utility power availability. Ideal for abundant solar resources.
• Solar Priority: Solar energy charges the battery first. Utility charges only when solar energy is unavailable. Suitable for areas with expensive grid power.
• Mains Priority: Utility power charges the battery first. Solar energy charges only when utility power is unavailable.
• Hybrid Charge: Both solar and utility power charge the battery. Recommended for unstable power grids to ensure backup supply.
