Figure 1: Cable Connection

NOTE

• Position the solar panel to shield the battery from direct sunlight.
• For detailed installation instructions, refer to the corresponding installation guide for your equipment: the 40W Solar Panel Kit Installation Guide for the solar panel, or the RAK7267 WisGate Soho Pro and RAK7240V2/RAK7240CV2 installation guides for the gateways.

Power ON and OFF

System Power ON

Important

Before powering on:

• Verify the polarity of the PV input and Load connections.
• Ensure all connectors are securely installed.
• Ensure the battery system is properly installed and grounded.

1. Press the ON/OFF power switch to turn on the battery system.
2. Verify that the system starts operating normally.

NOTE

The LED behavior depends on the solar input condition.

• After power-on, the green LED remains solid on for approximately 3 seconds before entering the normal operating state.
• When solar power is available, the green LED remains solid on.
• When solar power is unavailable, the green LED flashes. If no load connection is established, the LED turns off after approximately 15 minutes, and the battery system enters sleep mode. When a load is connected, the green LED continues flashing.

System Power OFF

Before powering off or disconnecting cables, do not disconnect the PV or Load cables while the battery system is operating.

1. Press the ON/OFF power switch to turn off the battery system.
2. Confirm that the system is powered off and that the LED indicators are turned off.
3. Disconnect the cables in the following order: first disconnect the PV Input cable, then disconnect the Load cable.
