Description
SUNBEAM system MINI-MPPT
Ultra-portable miniaturized solar charge controller
This compact yet powerful device builds on the success of the Mini-R and now features MPPT functionality, which increases the efficiency of solar panels. It supports solar panels up to 140W, another improvement over its predecessor. Despite its small size, its robust miniature design ensures low power consumption and exceptional portability.
The SUNBEAMsystem MINI-MPPT is a compact, efficient solar charge controller. Its key features are:
- MPPT optimization: Increases charging efficiency by 30-35%, in certain scenarios by up to 50%.
- Compatibility: Supports various battery types, including lead-acid and LiFePO4.
- User interface: Informative display with important data and a multi-function control button.
- Safety: Equipped with protection functions against reverse polarity, overtemperature and overcharging.
- Resistance: Protection class IP45 for splash water and dust protection.
- Energy efficient: Low self-consumption of 0.009 A.
Overall, the MINI-MPPT combines advanced charging technology, versatility and user-friendly features in a durable, energy-efficient package.
With MPPT optimization
This feature allows for an average increase in total charging capacity of 30-35%, and in some cases even 50%, compared to the older Mini-R.
Extended 4-stage charging with preset battery types:
Compatible with most lead-acid batteries and LiFePO4 batteries, therefore suitable for vehicles and yachts.
Informative display
Displays battery voltage, charging current, device temperature, and error codes. It also shows the selected battery type and charging status. A multifunction button allows control of settings and information display.
Built-in safety features
Equipped with electronic protection devices, including reverse polarity, over-temperature and overcharge protection.
Splash-proof and dust-proof
Corresponds to protection class IP45.
Low self-consumption
0.009A
Supported battery types
standard
Standard batteries, sealed batteries, SMART LITHIUM (not for storage) and AGM (must allow 14.6V every 7 days).
gel
A gentle program for gel batteries and also special AGM batteries that do not support 14.6 V.
LiFePO4
For LiFePO4 batteries, including SMART LITHIUM charging.
| GEL* | HOURS* | LiFePO4 | |
| Boost charging voltage | 14.2V | 14.4V | 14.4V |
| Maintenance charging voltage | 13.8V | 13.8V | No trickle charge |
| Equalizing charging voltage | No EQ | EQ 14.6V | No EQ |
| Boost Charge Recovery V. | 13.2V | 13.2V | - |
| Over-discharge recovery V. | 12.6V | 12.6V | 12.6V |
| Over-discharge voltage | 11.1V | 11.1V | 11.1V |
| Temperature compensation | -3Mv/2V/0ºC | -3Mv/2V/0ºC | - |
Lead-acid batteries require temperature compensation to prevent overcharging in hot weather and undercharging in cold weather. LFP batteries, on the other hand, do not require this compensation; therefore, the charger will not compensate when set to LFP mode.
Intelligent 4-stage charging
CC/Boost
Constant current phase (charging only occurs as much as the solar module can supply).
Balancing/Desulfurization
Included in the standard program. Activated every 7 days and only with a constant connection. Rejuvenates lead-acid batteries by extending the constant current (CC) phase up to 14.6 V.
CV / Absorption
Constant voltage phase (end of the high-charge phase).
Maintenance charging / servicing
It maintains a fully charged battery, which is necessary for lead-acid batteries but not desirable for LFP batteries. SMART LITHIUM can maintain this if you use your vehicle daily, but if you are not using it, you should switch to the LFP settings to turn this off.

Technical data
Loading algorithm: MPPT
Battery types: GEL | AGM | SEALED | LiFePO4
Battery system voltage: 12V
Maximum current: 10A
Maximum PV power: 140W
Maximum PV power: 30Voc
Self-consumption: 0.009A
Operating temperature range: -30ºC to 50ºC
Protection against dust and water: IP45
Weight: 160g (including protective case)
Dimensions: 10.2 x 6.5 x 2.7 cm
Usage restrictions
Maximum capacity: The device can handle solar modules with a power output of up to 140 watts and an open-circuit voltage (Voc) of 30 V. If multiple solar modules are to be connected, only a parallel connection is supported; series connection (solar modules) is not.
Battery settings: Consult your battery manufacturer's manual to find the appropriate settings for your battery. The default settings should be sufficient for most battery types, although some manufacturers may have specific charging requirements.
IP45 rating: The device is protected against light splashes of water, but should not be submerged in water.
Recommended battery size: For practical reasons, it is recommended to keep the total battery capacity below 300-400Ah. While the device is compatible with larger batteries, charging times will increase significantly. Please also consider the reduced sunlight during winter when using the device for trickle charging.
