The new MoonRay MPPT solar charge controllers are truly optimized for use on yachts and RVs. MoonRay outperforms other MPPT charge controllers. Tested in both perfect as well as ‘real-life’ weather conditions. It’s performance outshines others in clouded or partial shadowing conditions.
The MoonRay is optimized for a typical installation on a boat or motorhome. Often, with a single solar panel or a couple of solar panels connected in parallel. Charging one or several 12V batteries.
Thanks to its versatility it is also possible to use many MoonRay’s together. Controlling groups of solar panels. This makes it possible to optimize each group. So you can make groups according to the ever-changing conditions on a moving platform. Thanks to the Multi Connect App it is possible to collect information from all the controllers as they were one.
*If you intend to connect your Moonray MPPT charge controller to a 24V system, note that you´ll need to use two or more solar panels connected in series.
MOONRAY IS NOT LIKE OTHER SOLAR CHARGE CONTROLLERS
Installing a solar panel system on a yacht or motorhome might be challenging. The solar panel industry mostly focusses on big fixed installations. However, SUNBEAMsystem aims is to make equipment for non-stationary vehicles and boats. Which requires the solar system setups to be much different from a home installation. One can identify five things that are essentially different in our line of business.
- Partial shadowing is much more frequent.
- Fewer or only one solar panel
- Prefer the connection of solar panels in parallel over serial
- Off-Grid charging of 12V or 24V* DC batteries, not 230V AC
- The need for power efficiency and power conservation (don’t waste energy)
- The use of high-efficiency solar cells
*If you intend to connect your Moonray MPPT charge controller to a 24V system, note that you´ll need to use two or more solar panels connected in series.

HOW DOES IT WORK?
The mentioned factors are the key to making a real charge controller optimized for yachts and motorhomes. And not just porting technology from a house roof installation.
MoonRay solves it all and this is how the optimization functions:
- Charging will start when the solar panel(s) reach a voltage of 0.1V above the battery voltage(sometimes <0.9V). Even with ever so little power, it will add up on the total stored energy over the day. Especially in countries with cloudy weather or with the sun at low angles.
- The energy efficiency curve is extremely flat. You could compare this with a fine-tuned combustion engine. Where you have a good pull starting at low RPM’s all the way up to high RPM’s. Whereas an old-style MPPT would rather be very efficient at a specific (high) RPM only. At the cost of having low or no output at lower RPM’s.
- The MoonRay is a high performer even if with a non-optimized random size on the solar panel(s). In other words, choose your solar panel size/watt without limitation.
- The MoonRay will harvest more during the natural power fluctuations up and down. And is not limited to perfect angles and solar irradiation.
- MoonRay features an optimized MPPT algorithm for a lower solar panel voltage. It is also adapted for a solar panel Vmp in the range of 17 to 25 Volts. This to charge a 12V battery with a single solar panel or likewise many solar panels. (remember that parallel is the best solar panel installation on a yacht/motorhome)
On top of this, the self-consumption of 13mA (14mA for 320) is industry-leading for an MPPT solar charge controller in this size range. Ensuring a low energy waste.

Competitor MPPT
Showing a typical peak, indicating the need for a minimum amount of solar panels and perfect weather conditions. Resulting in bad efficiency most of the time.
