Installation Tools
Prior to installation, prepare the following tools:

Installing the Device
Before choosing an installation location, consider the following points:

• Do not install the inverter on combustible building materials.
• Install it on a solid surface.
• For proper air circulation and adequate heat dissipation, leave approximately 150cm of space on both sides, the top, and the bottom of the device.
• The ambient temperature should be maintained between – 10°C and 45°C to ensure optimal operation.
• Ensure that other objects are positioned at a safe distance from the inverter surface as shown in the example diagram, to allow for proper heat dissipation and sufficient space for wiring removal.

Note: Only suitable for installation on concrete or other non-combustible walls.
To install the unit, use 4 screws. It is recommended to use M4 or M5 screws.

Battery

AC Output

Enclosure Grounding
Please follow the diagram below to complete the grounding of the inverter enclosure.

NOTE

• Ensure the inverter enclosure is grounded first. If the device enclosure becomes live due to a fault, grounding will quickly direct the current to the ground, preventing electric shock from contact with the live enclosure.

Battery Connection
Connect the positive and negative terminals of the battery as shown in the diagram below. Be sure to install breakers that meet the required specifications on the battery lines.

1. First, connect the positive and negative battery cables to the battery terminal block.
2. Then install the terminal cover.

NOTE

• The POW-HV-EU series inverter’s battery lines come with spare replacement fuses. Use them as needed.
• After completing the connection, carefully check if the positive and negative cables are connected correctly and if the terminals are securely fastened.

Remote Control Panel Connection
Connect the remote control panel to the inverter using the dedicated communication cable provided in the package.

Operation

Starting the Inverter
After closing the battery circuit breaker, start the inverter using the power switch on the inverter body or the power switch on the remote control panel.

NOTE

• The switch on the remote control panel and the switch on the inverter body are independent.
• If you start the inverter using the power switch on the inverter, you must use this switch to turn off the inverter; you cannot use the remote control panel to do so.
• Similarly, if you start the inverter using the remote control panel, you must use the remote control panel to turn it off.

Connecting Loads

1. After the inverter starts normally, connect the plugs of the loads.
2. Ensure all cables are properly installed and securely connected.

DANGER

• Before connecting the AC output, ensure all loads are in the off state. Do not operate while the system is live.
• Check that the cables used meet the requirements. Thin or poor-quality cables pose serious safety hazards.

Remote Control Panel Overview

Functions of the Remote Control Panel

• Remote control of the inverter’s power on/off status.
• View battery voltage through the LCD display.
• Display battery capacity.
• Display inverter status.

NOTE

• The switch on the remote control panel and the switch on the inverter body are independent. If you start the inverter using the power switch on the inverter, you must use this switch to turn off the inverter; you cannot use the remote control panel to do so.
• Similarly, if you start the inverter using the remote control panel, you must use the remote control panel to turn it off.

Protection Functions

Troubleshooting

System Maintenance
