3. 安全に関する注意事項

Please read all instructions carefully before installation and operation. Failure to follow these instructions may result in damage to the controller, battery, or solar panels, and may void the warranty.

• Ensure the battery is connected first to allow the controller to recognize the system voltage.
• Always connect the solar panels and load after the battery.
• Disconnect the solar panels and load before disconnecting the battery.
• Install the controller in a well-ventilated, dry, and cool environment, away from flammable materials.
• Avoid touching or short-circuiting wires or terminals.
• 過熱を防ぐために、すべての接続に適切なワイヤゲージを使用してください。
• This device is for indoor use only. Avoid exposure to water or excessive humidity.
• お子様の手の届かない場所に保管してください。

4. インストール

4.1 配線手順

1. Connect the battery to the charge controller. Ensure correct polarity (+ to + and - to -). The controller will display the battery voltage.
2. Connect the solar panel to the charge controller. Ensure correct polarity. The controller will begin charging the battery.
3. Connect the load to the charge controller. Ensure correct polarity.

重要： Always connect the battery first and disconnect it last. This sequence prevents damage to the controller from voltageサージ。

4.2 取り付け

Mount the controller vertically on a wall or flat surface in a well-ventilated area, away from direct sunlight, high temperatures, and water. Ensure there is sufficient air circulation around the heat sink.

5. 操作

5.1 LCDディスプレイとボタン

The controller features an LCD display and three buttons for operation: UP, DOWN, and SET.

• 上ボタン： Navigates through display interfaces, increases parameter values.
• 下ボタン： Navigates through display interfaces, decreases parameter values.
• SETボタン： Enters/exits setting mode, confirms parameter changes.

5.2 Browsing Display Interfaces

Press the UP or DOWN button to cycle through various display interfaces, including battery voltage, charging current, accumulated discharge, and load status.

5.3パラメータ設定

To enter the setting interface, long-press the SET button for 5 seconds. Use the UP and DOWN buttons to adjust values and the SET button to confirm and move to the next parameter. Long-press SET again to save changes and exit.

調整可能なパラメータは次のとおりです。

• 電池のタイプ： Select the correct battery type (e.g., Lead-Acid, Lithium).
• 負荷制御モード: Set timer for load operation (e.g., 24H for continuous, 16H for dusk-to-dawn).
• チャージVoltage: Adjust maximum charge voltage.
• 放電カットオフVoltage: 最小音量を設定するtage before load disconnection.
• 放電再接続ボリュームtage: ボリュームを設定するtage at which the load reconnects.

Refer to the "Specifications" section for default and adjustable ranges for each parameter.
