Compact MPPT Charge Controller with Bluetooth

Powerful Despite Its Size
SUNBEAMsystem introduces the MoonRay SLIM – a new generation of compact MPPT charge controllers that deliver outstanding performance and power in an ultra-slim format. It’s smaller than the competition but outperforms many with superior charging efficiency and ease of use.
Compact MPPT Charge Controller
Ultra-low self-consumption
Up to 200W (400W)
Built-in Bluetooth
IP45 Protection
For 12v/24V Batteries
Earlier Start – Later Finish
Thanks to an exceptionally low voltage threshold, the MoonRay SLIM begins charging early in the morning and continues late into the evening. It’s ideal for shaded installations like boats or mobile setups – no need to wire panels in series to compensate for weak controllers, ensuring maximum daily energy harvest.
Flexible Mounting & Full Protection
The MoonRay SLIM is just as suited for wall-mounting as it is for mobile use in boats, RVs, or off-grid systems. With 8 built-in electronic protections, it’s a safe and reliable choice – even for sensitive electrical installations.

Smart Control via Bluetooth
With built-in Bluetooth and SUNBEAMsystem Mobile Smart Home compatibility, you get full control of your system both locally and remotely. Everyone in the family can access real-time data and system status via the app – wherever they are.
Display and Intuitive Control
An integrated screen provides quick access to key information. The convenient multifunction button lets you switch between three battery types directly on the device. Through the app, you can choose from preset battery profiles – including lithium and classic – or create a fully customized profile tailored to your setup.


Built for Harsh Environments
The MoonRay SLIM is dustproof and splash-resistant, making it perfect for marine environments, RVs, and off-grid use. Despite weighing just 350 grams, it handles up to 400W at 24V and features an ultra-low self-consumption of only 0.009A.
