Morningstar SunLight 10amp/24v/LVD
Morningstar SunLight 10amp/24v/LVD
10-Position Rotary Timer with Built-in Low Voltage Disconnect

DESCRIPTION
Advanced 24V Solar Lighting Control
The Morningstar SunLight 10A 24V solar lighting controller is engineered to provide precise, automated management of off-grid solar lighting systems. Designed for 24V applications, this sophisticated regulator combines standard solar charge control functions with an industry-leading lighting controller, making it an optimal choice for street lighting, pathway illumination, security lights, and remote bus shelters.
Operating with a maximum current rating of 10 amps, it efficiently manages solar arrays while ensuring your battery bank is protected and your lighting operates exactly when required. Note that standard environmental de-rating factors apply when sizing your solar array.
Customisable Timer Profiles
A standout feature of this lighting regulator is the intuitive 10-position rotary control dial. This integrated interface allows users to quickly select from a variety of pre-programmed lighting timer profiles. Whether the requirement is dusk-to-dawn operation, or specific post-dusk and pre-dawn intervals, the rotary dial eliminates the need for complex digital programming interfaces and ensures reliable, set-and-forget operation in the field.
Integrated Low Voltage Disconnect (LVD)
Protecting the health of off-grid battery banks is critical. The built-in Low Voltage Disconnect (LVD) feature actively monitors the 24V battery system. If the voltage drops to a critical level, the controller automatically disconnects the lighting load. This essential safeguard prevents deep discharging, significantly extending the life cycle of your lead-acid batteries. The unit also includes internal jumper settings, allowing technicians to easily switch the charging profile between sealed and flooded lead-acid battery chemistries.
Diagnostic and Testing Capabilities
System verification and troubleshooting are simplified through integrated diagnostic tools. Dual LED status indicators provide immediate visual feedback regarding the current charging status and offer early warnings for low voltage disconnect events. Furthermore, a dedicated manual test button is available on the faceplate, allowing installers and maintenance personnel to instantly verify system operation and load functionality during daytime installation or routine checks.
Key Features
- 10-Position Rotary Dial: Quick and easy selection of multiple lighting timer profiles.
- Low Voltage Disconnect (LVD): Protects 24V battery banks from damaging deep discharges.
- Dual LED Indicators: Provides clear charging status and low voltage warnings at a glance.
- Manual Test Button: Enables rapid system verification and troubleshooting in the field.
