SCM60 MPPT-MB Solar Charge Controller

The Mastervolt SCM60 MPPT-MB solar charge controller is a fully automatic battery charger that uses power supplied by photovoltaic (PV) solar panels. Its primary function is to optimize the energy output from your solar panels to charge your batteries up to 30% faster than conventional controllers, thanks to MPPT (Maximum Power Point Tracking) technology.

The SCM60 MPPT-MB regulator automatically adapts to 12 V, 24 V, or 48 V battery systems. It is compatible with all battery types, including AGM, gel, flooded, and Mastervolt Lithium Ion batteries. Charge profiles are preprogrammed for each battery type.

The SCM60 MPPT-MB charge controller can handle a solar input power range from 600 Wp to 3600 Wp. Specifically, it supports a maximum PV power of 900 Wp for a 12 V system, 1800 Wp for a 24 V system, and 3600 Wp for a 48 V system.

The maximum PV input voltage that the SCM60 MPPT-MB controller can accept is 145 V.

Yes, the SCM60 MPPT-MB supports various types of solar panels, including 36, 60, and 72-cell models. Its maximum PV input voltage of 145 V allows connecting multiple panels in series, reducing cable lengths and simplifying installation.

The controller uses a three-stage automatic charging algorithm:

BULK: During this phase, the charger delivers maximum power for fast charging from 0 to 80%. ABSORPTION: The charger has reached its maximum charging voltage, and the current decreases until the battery is fully charged (100%). FLOAT: This phase starts when the battery is fully charged and maintains it in a fully charged state. Installing the battery temperature probe allows automatic adjustment of charging voltages to temperature variations.

Yes, the Solar ChargeMaster SCM60 MPPT-MB is protected against overloads, short circuits, overheating, battery voltage drops and spikes, high/low PV voltage, and reverse polarity. However, it is not protected against overvoltage on the solar input or against induced overvoltage from lightning.

The SCM60 MPPT-MB controller housing has an IP23 protection rating. This means it is protected against finger contact and water spray up to 60° from the vertical. It is designed for indoor use and must be protected from harsh environments, ammonia, or salt.

The SCM60 MPPT-MB integrates natively with Mastervolt's MasterBus network. This connectivity provides advanced monitoring and centralized control functions, enabling enhanced automation of your energy system, such as triggering a water heater or direct management of Lithium Ion batteries without external relays.

The SCM60 MPPT-MB controller operates within an ambient temperature range of -20 °C to 55 °C. It is important to note that a power reduction may occur above 40 °C to lower the internal temperature of the heat sink.

The SCM60 MPPT-MB charge controller has dimensions of 398 x 168 x 104 mm (Height x Width x Depth) and weighs 5.5 kg.

The Solar ChargeMaster does not require any special maintenance. It is recommended to regularly check your electrical installation (at least once a year) and immediately address any faults such as loose connections or burnt cables. If necessary, clean the housing with a clean, soft cloth, without using liquids, acids, or abrasive powders.

The controller must be mounted on a solid, heat-resistant vertical surface, with the connectors facing downward. It should be installed in a ventilated indoor space, at least 20 cm away from each side and 50 cm above and below any object to ensure proper airflow. Do not install it in the same compartment as the batteries, nor directly above them due to potential corrosive sulfur emissions.

Yes, using an external DC switch is highly recommended. When the PV field is exposed to light, it supplies a DC voltage to the MPPT Solar ChargeMaster that can be dangerous to touch. An external switch allows you to disconnect the controller from power sources (PV and batteries) before any maintenance or cleaning.

The SCM60 MPPT-MB is compatible with Mastervolt Lithium Ion batteries. Thanks to MasterBus integration, it can directly manage these batteries, eliminating the need for manual relay adjustments typically required for this battery type. Pre-programmed charge profiles are also available for Lithium Ion batteries.

If the internal temperature of the Solar ChargeMaster exceeds 80°C, the output power will decrease (LCD indication 22). If the temperature continues to rise, an error (02 + ERROR) will be displayed. It is then necessary to check the cooling system and installation environment to ensure that air circulation along the heatsink is not obstructed.

The controller includes a temperature-compensation function. Using a battery temperature probe, it automatically adjusts charging voltages. When battery temperature is low, charging voltage increases; when temperature is high, charging voltage decreases. This prevents overcharging and gassing, extending battery life.

No, the SCM60 MPPT-MB is designed with a passive cooling system, making it very quiet during operation.
