Saulės energijos reguliatorius MPPT SCM25 Mastervolt

The maximum charge current of the Mastervolt MPPT SCM25 solar charge controller is 25 A at 40 °C. This value is essential for correctly sizing your solar installation and batteries.

The SCM25 is designed for solar installations with a power output between 200 and 700 Wp. Specifically:

At 12 V: maximum power of 360 WpAt 24 V: maximum power of 720 WpThese values ensure optimal and safe operation of the charge controller.

Yes, absolutely. The SCM25 MPPT charge controller is specifically designed to be compatible with entry-level 60-cell solar panels, in addition to traditional 36-cell and 72-cell models. This makes it highly versatile for different panel configurations.

The SCM25 is compatible with a wide range of batteries:

AGM, Gel, Flooded (open lead-acid), Lithium Ion (Mastervolt). Charge profiles are pre-programmed for each type and can be easily selected via the power button.

Yes, the SCM25 regulator has an automatic 12/24 V detection function. It automatically adapts to your system’s voltage, simplifying installation and preventing manual configuration errors.

The maximum PV input voltage (at minimum temperature) is 75 V. Under nominal operation, the PV voltage must be between:

15 and 66 V for a 12 V installation, and 30 and 66 V for a 24 V installation. It is important to respect these limits to avoid damaging the regulator.

Yes, the SCM25 charge controller is supplied with a battery temperature sensor. It automatically adjusts charging voltages based on battery temperature, optimizing charging and extending battery life.

The SCM25 regulator has an IP23 protection rating. This means it is protected against finger contact and water splashes up to 60° from the vertical. It is suitable for indoor use in dry or humid environments, but not for outdoor exposure to rain.

The manual states that the SCM25 is compatible with Mastervolt lithium-ion batteries. For a lithium battery from another brand, it is imperative to verify the compatibility of charge profiles and voltages. If in doubt, consult the battery manufacturer or a qualified installer.

To select the battery type, hold the Power button pressed for more than 5 seconds. The LCD screen will then display the different pre-programmed charge profiles (AGM, gel, flooded, Lithium Ion). Use the button to navigate and confirm your selection.

Yes, the SCM25 is equipped with a switched output 'Load' (consumer) capable of supporting a maximum current of 25 A. This output can be used to power DC equipment, with built-in protection against overloads and short circuits.

The SCM25 dimensions are 135 x 190 x 75 mm (height x width x depth). Its weight is approximately 1.3 kg. These compact dimensions make it easy to install in confined spaces, such as on a boat or in a campervan.

The SCM25's power consumption when solar production is absent (at night) is extremely low, around 5 mA. This preserves the battery without discharging it unnecessarily. The controller automatically switches to sleep mode to reduce its power draw.

No, it is not recommended to install the SCM25 in the same compartment as the batteries. Batteries can release explosive gases and corrosive vapors. It should be installed in a separate, well-ventilated location, protected from water spray.

The SCM25 regulator can operate within an ambient temperature range of -20 °C to 55 °C. Above 40 °C, power is automatically reduced to protect internal components. Cooling is passive (fanless), making it silent.

Yes, the SCM25 is fully compatible with 200 Wp solar panels. The recommended power range is 200 to 700 Wp, which includes 200 Wp panels. At 12 V, the maximum power is 360 Wp, so a 200 Wp panel is within the limits.
