The SCM25 MPPT is Mastervolt’s smallest MPPT charge regulator and just as powerful as its big brother. With 200 to 700 Wp in solar panels, switchable output, and buzzer, this Solar ChargeMaster is very well suited to small and medium systems.The innovative technology in the Mastervolt MPPT charge regulators increases the efficiency of the solar panels. The SCM25 MPPT charges your batteries up to 30 % faster than PWM regulators – with the same number of panels.MPPT charge regulator for all solar panelsBesides the traditional 36 and 72-cell panels, the SCM25 MPPT is also ideal for the inexpensive 60-cell panels.Easy to use, safe, and flexibleThe SCM25 MPPT is suitable for all battery types, including Mastervolt Lithium Ion. The charging profiles for all types of batteries are pre-programmed and can be selected at the push of a button. The SCM25 MPPT is quiet and equipped with a very user-friendly, clear display. Built-in protection against overload, high/low battery voltage, overheating, short circuits and reverse polarity ensures that safety comes first. Moreover, the SCM25 MPPT has a robust casing and is protected against condensation in conformity with IP23.FeaturesVery high efficiency for faster chargingStable, accurate Mastervolt maximum power point trackerUp to 30% faster charging compared with PWM technologySuitable for inexpensive 60-cell panelsCapacity for solar panel configurations from 200 to 700 WpAutomatic 12/24 V detectionFlexible charging characteristicsBattery temperature sensor for long lifespanLarge and bright displaySecure switchable outputSafe operation, audio signal in case of malfunctionsVery quiet operationRobust casing, suitable for humid environments (IP23)Specifications Battery ChargerMaximum charge current at 40C/104F: 25 ASystem voltage (battery): 12/24 V auto selectBattery types: AGM, gel, wet, Lithium IonBattery temperature sensor: YesLithium Ion protection: Via multipurpose contact output (product code 77030500)Switchable output (maximum current): 25 AEnergy consumption (night): 5 mASpecifications Solar Input (DC)Nominal PV current at 40C/104F: 18 APV start voltage (12/24 V): 15 V/27 VNominal PV voltage (12 V): 15-66 VNominal PV voltage (24 V): 30-66 VMaximum PV voltage (Tmin): 75 VMaximum PV power (12 V): 360 WpMaximum PV power (24 V): 720 WpMaximum efficiency: >98%Static MPP efficiency: 99.9%General SpecificationsCooling: PassiveDisplay/read-out: Backlit LCD with PV power, load power, battery voltage, charge current, warnings, battery state of charge, battery settingGrounding: (-) TerminalAlarms: BuzzerProtection degree: IP23Dimensions (H x W x D): 135 mm (5.3″) x 190 mm (7.5″) x 75 mm (3″)Weight: 1.3 kgTechnical SpecificationsTechnology: MPPT (Maximum Power Point Tracker)Temperature range (ambient temperature): -20C to 55C/-4F to 131FCable size: Maximum 10 mm Litz wireProtections: Over temperature, overload, high/low battery voltage, high/low PV voltage, short circuit, reverse polarity, and HV transientsRelative humidity: 95% non-condensingOptional ExtraTemperature sensor 6m MV41500500Temperature sensor 15m MV41500800DownloadsUser Manual Datasheet .input-wrapper a { text-decoration: none; / Removes underline / background-color: transparent; / Ensures no background color / } .input-wrapper a:hover { text-decoration: underline; / Adds underline on hover / background-color: transparent !important; / Removes grey highlight / }
