Schneider POS 11401 | Solar Panel Lamp Controller 12/24V

The POS 11401 manages solar panel charging and lamp operation automatically. This controller regulates battery charging from photovoltaic panels efficiently. It also controls LED or CFL lamp output based on ambient light levels. Consequently, you get reliable off-grid lighting for gardens, pathways, or remote sites.

You can install this controller between your solar panel and battery bank. The POS 11401 handles both 12V and 24V system voltages automatically. It includes overcharge, over-discharge, and reverse current protection features. Therefore, your battery and lamps remain safe from electrical damage.

Electrical Specifications and Power Ratings

The controller supports a maximum solar input of 150 watts at 12V. The POS 11401 handles up to 300 watts when operating at 24V systems. Its rated charge and load current reaches 10 amperes continuously. The unit automatically detects system voltage upon initial connection.

Three LED indicators show charging status, battery level, and load condition. The POS 11401 uses Pulse Width Modulation for efficient battery charging. This method extends battery life by preventing harmful overcharging. Below is a complete breakdown of its technical characteristics.

Interface and Connection Layout

The controller features four terminal pairs for system connections. The POS 11401 labels terminals for solar panel, battery, and lamp outputs. Each terminal accepts wire sizes from 1.5 to 6.0 mm². A small LED display shows the current operating mode and battery voltage.

You can adjust the lamp timer from dusk to dawn manually. The POS 11401 also offers 1 to 15 hour timer settings. A push button on the front forces lamp activation for testing purposes. Therefore, installation and configuration require no special software tools.

Operational Benefits for Solar Lighting

This controller automates outdoor lighting without manual intervention. The POS 11401 turns lamps on at dusk and off at dawn. It protects batteries from deep discharge during extended cloudy periods. Engineers value this unit for reliable solar street lighting and garden applications.
