## Summary description

AIREN SilverFour+ 400W 12V solar panel designed to generate up to 400 watts of DC power at a 12‑volt nominal system. Suitable for off‑grid, mobile or backup power setups, it provides a compact solution for charging 12V batteries and supplying DC loads. Use cases include caravans, boats, cabins and small off‑grid installations where a 12V output is required.

## Long description

Aluminium 5.25" front panel with red LEDs providing control for up to four 3‑pin fans and offering front I/O ports including 2x USB 2.0, 1x eSATA and a power connector. The unit monitors fan rotation and triggers an alarm if a fan stops. Panel dimensions are 149×42×68 mm and it accepts a +12V input; regulated outputs range from 5 to 11.8V with a maximum combined power of 30W. Included accessories: mounting screws, four fan connection cables, one power cable, one SATA power cable and one USB cable.
Advantages
The aluminium construction with integrated side rails fits a standard 5.25" drive bay and provides durable mounting for high‑RPM fans. Red LEDs indicate operating status; the built‑in speed control lets you adjust fan voltage and reduce noise or increase airflow as needed. A stop‑running alarm notifies you immediately of fan failure, and front ports give convenient access to USB 2.0 and eSATA connections.
Suitable for
Desktop PC systems requiring additional fan control
High‑RPM cooling setups where monitoring and alarm are needed

Attach up to four 3‑pin fan connectors to the dedicated fan outputs and connect front devices to the USB or eSATA ports as required. Adjust fan speed using the panel controls to set desired voltage between 5 and 11.8V, ensuring the total connected load does not exceed 30W. If a fan stops, the alarm indicator will activate.
Usage recommendations
Verify total power draw of connected fans and devices before operation to avoid exceeding the 30W limit. Use in well‑ventilated drive bays and secure all cables to prevent strain on connectors. Replace failed fans promptly when the stop‑running alarm appears.
