Advanced 24V Solar Lighting Control with the Morningstar SunLight 20A

The Morningstar SunLight 20A 24V controller is engineered specifically for off-grid lighting applications. Combining the proven reliability of Morningstar charge controllers with an advanced, automated lighting control circuit, this unit provides precise management of your solar lighting systems. Whether you are illuminating a remote pathway, powering industrial security lighting, or managing rural signage, this controller ensures your lighting operates efficiently and your battery bank remains protected.

Automated Dusk-to-Dawn Lighting Management

One of the primary challenges in off-grid solar lighting is ensuring lights activate precisely when needed without draining the battery prematurely. The SunLight controller solves this with a built-in rotary control dial, allowing users to configure lighting duration with exceptional accuracy. You can easily set the system for dusk-to-dawn operation or limit the lighting time to specific hours after sunset. This eliminates the need for external timers or light sensors, streamlining your installation and reducing potential points of failure.

Comprehensive Battery Protection

A critical aspect of any remote solar installation is battery longevity. This controller includes a vital Low Voltage Disconnect (LVD) feature. The LVD continuously monitors the 24V battery bank and automatically disconnects the lighting load if the voltage drops below a critical threshold. This prevents deep discharge events, which are the leading cause of premature battery failure in off-grid setups.

Additionally, a built-in battery type selector allows you to configure the charging profile for either sealed or flooded lead-acid batteries, ensuring the charge parameters precisely match your specific battery chemistry.

Intuitive System Monitoring and Testing

Commissioning and troubleshooting are simplified through integrated diagnostic features. The controller is equipped with clear LED indicators: a green LED confirms when the solar panel is actively charging the battery, while a red LED alerts you when the LVD has engaged. Furthermore, a dedicated manual test button allows installers to instantly verify the lighting circuit and system functionality during daytime installation, saving time and ensuring everything is wired correctly before leaving the site.

Key Features for Professional Installations

• 24V 20A Capacity: Suitable for medium to large off-grid solar lighting arrays.
• Rotary Timer Dial: Provides precise control over lighting duration and dusk-to-dawn settings.
• Low Voltage Disconnect (LVD): Protects your battery bank from damaging deep discharges.
• Battery Type Selector: Optimised charging profiles for sealed and flooded lead-acid batteries.
