Morningstar SunLight 20amp/12v/LVD

Advanced 20A Solar Lighting Regulation for 12V Off-Grid Systems

Managing automated lighting in remote and off-grid locations requires more than a standard charge controller. It demands precise load control, reliable battery protection, and intuitive configuration. The Morningstar SunLight 20A 12V Solar Lighting Controller is engineered specifically to meet these needs, combining high-quality solar charging with sophisticated lighting automation in a single, robust unit.

Designed for 12V DC systems, this 20A regulator offers the perfect balance of flexibility and automated operation. Whether you are illuminating an isolated bus shelter, securing an agricultural shed, or setting up pathway lighting, this controller ensures your lighting activates precisely when needed while safeguarding your battery bank against premature failure.

Intelligent and Programmable Lighting Control

At the core of this unit is a highly versatile rotary control dial that provides 10 distinct lighting options. Users can easily select between traditional dusk-to-dawn operation or specific timed settings that turn the lights off after a predetermined number of hours. This level of control is crucial for conserving battery power during long winter nights or extended periods of overcast weather. By only running the lights when necessary, the overall load on the system is significantly reduced.

For commissioning and ongoing maintenance, the integrated test button offers an immediate way to verify system performance. Instead of waiting for nightfall to confirm your wiring and timer settings, a simple press of the button activates the lighting load, allowing for rapid deployment and straightforward troubleshooting.

Robust Battery Protection with Low Voltage Disconnect

Batteries represent the most critical and expensive component of any off-grid solar installation. To maximise battery lifespan, this controller features an integrated Low Voltage Disconnect (LVD). When the battery voltage drops to a critical threshold, the LVD automatically disconnects the lighting load, preventing the damaging deep discharges that can permanently ruin lead-acid batteries.

Monitoring the system status is simple thanks to the clear LED interface. A green LED provides continuous feedback on solar charging activity, while a dedicated red LED instantly alerts users when the LVD has been triggered. This visual feedback is invaluable for understanding system health at a glance.

Versatile Design and Secure Connections

Accommodating different battery chemistries is essential for optimal charging. The controller includes a user-selectable jumper, making it simple to switch the charging profile to suit either sealed or flooded batteries. This ensures the correct voltage setpoints are applied, further extending the operational life of the battery bank.

Installation is straightforward, facilitated by large, accessible screw terminals. These oversized terminals ensure a secure, low-resistance connection for the solar array, the battery, and the lighting circuits, reducing the risk of voltage drop and terminal heating over time.
