It offers 10 customizable lighting modes, automatic day/night detection, and battery protection through low voltage disconnect and temperature compensation, ensuring efficient and reliable solar energy management for 12V systems. ## Description Solar lighting controller includes advanced microcontroller for automatic lighting control functions 10 field adjustable lighting control options Low Voltage Disconnect Temperature Compensation Includes SunSaver battery charging circuit 20 amps, 12 volts Review: It works beautifully right out of the box - I'm using this product with my two 100-Watt Renogy mono-crystalline solar panels. It's charging a 12V battery during the day and running lights from the battery at night. The entire system is off-grid and is working in a completely dry environment that experiences the full range of America's North East temperature range. (I.E., Approximately 0-degrees F to 100-degrees F.) It works beautifully right out of the box. I'm using the SunLight to time control 12-V LED pathway lights and re-charge a 12V flooded battery.) (I've successfully tested the SunLight's various built-in timing functions to control the load (ie LED path lights) ) I've observed perfect operation of the system, as well as automated shut-down when the battery charge level drops too low. I have no complaints and so far (~5 months) it works perfectly. I like the product. Review: Incredible AT First, Problems Now - This is a great product that not only works as expected but it was also easy to install. My garden uses extensive yard and deck lighting, all of which were LED or converted to LED prior to the installation of the solar system. This device, in conjunction with a 100 Watt solar panel on the roof and an 80 AHr battery, provides about six hours of lighting after a sunny day. The only improvement would be to remove the feature that shuts it down once the battery discharges to 11.7 v as standard 12v LED lighting is capable of running efficiently on lower voltages without problem and this is really designed for lighting. This limit is hard-wired into the device but making it user-adjustable (or non-existent) would be ideal. I had to take off a star because of the limitation. UPDATE: After using this for a while, I am discovering that with only a minimal load of LED garden lights (I disconnected all but a few for testing), it shuts them off prematurely. When it does, the low voltage indicator comes on while the battery itself still has over 13.5 volts available. A little while later the lights come on again, then go off again over and over. Morningstar replaced the unit but the replacement does the same thing and now they no longer respond to support requests so steer clear! ## Features - Morningstar's SunLight is the world's leading solar lighting controller - solar array voltage to determine day and night - SunLight's ON/OFF/ON options ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008H723E4 | | Brand | Morningstar Corporation | | Colour | white/black | | Customer Reviews | 4.7 out of 5 stars 12 Reviews | | Display Type | Digital | | Display type | Digital | | Item Weight | 254 g | | Item weight | 254 g | | Manufacturer | Morningstar | | Manufacturer Part Number | SL-20L-12V | | Material | Plastic | | Model Number | SL-20L-12V | | UPC | 733556560093 | | Voltage | 12 Volts | ## Product Details - **Colour:** white/black - **Brand:** Morningstar Corporation - **Voltage:** 12 Volts - **Item weight:** 254 g - **UPC:** 733556560093 ## Images ![Morningstar SunLight Charge Controller SL-20L-12V by Morning Star - Image 1](https://m.media-amazon.com/images/I/717cSQVsbpL.jpg) ![Morningstar SunLight Charge Controller SL-20L-12V by Morning Star - Image 2](https://m.media-amazon.com/images/I/71G+z5FIyfL.jpg) ![Morningstar SunLight Charge Controller SL-20L-12V by Morning Star - Image 3](https://m.media-amazon.com/images/I/71i+ApBIe+L.jpg) ![Morningstar SunLight Charge Controller SL-20L-12V by Morning Star - Image 4](https://m.media-amazon.com/images/I/61zjwLc06vL.jpg) ![Morningstar SunLight Charge Controller SL-20L-12V by Morning Star - Image 5](https://m.media-amazon.com/images/I/71kkfNYjjJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works beautifully right out of the box *by P***K on 23 December 2014* I'm using this product with my two 100-Watt Renogy mono-crystalline solar panels.
