Mastervolt 131824000 Solar ChargeMaster SCM40 PWM

Mastervolt Solar ChargeMaster SCM40 PWM (131824000)

The Mastervolt Solar ChargeMaster SCM40 PWM (131824000) is a high-capacity 40-A Pulse Width Modulation (PWM) solar charge controller engineered for marine, mobile, and off-grid 12V and 24V DC battery systems. Designed to manage photovoltaic array outputs up to 700 Wp (12V) or 1400 Wp (24V), it provides optimal 3-stage battery charging (Bulk, Absorption, Float) for AGM, Gel, Lead-Acid, and Lithium-Ion (LiFePO4) battery chemistries.

Equipped with a clear, backlit digital LCD screen, the SCM40 PWM displays real-time solar yield, battery voltage, charging current, and system load status. It features an integrated 40A switchable load output with low-voltage disconnect (LVD) to prevent deep discharge of battery banks, alongside automatic ambient temperature compensation and comprehensive protection against reversed polarity, short circuits, and thermal overload.

Key Features

• 3-Stage Intelligent PWM Charging: Optimizes battery health with Bulk, Absorption, and Float charge cycles.

• Integrated Backlit Digital Display: Provides real-time metrics including battery voltage, PV charge current, load current, and battery state-of-charge.

• Switchable 40A Auxiliary Load Output: Integrated low-voltage disconnect (LVD) protects battery banks from damaging over-discharge.

• Automatic System Voltage Recognition: Automatically detects 12V or 24V DC battery system configuration upon startup.

• Multi-Chemistry Compatibility: Selectable battery presets for Lead-Acid, Gel, AGM, and Lithium-Ion (LiFePO4) batteries with optional temperature compensation.

• Solid-State Electronic Protection: Built-in protection against reverse PV/battery polarity, short circuits, overtemperature, and reverse current flow at night.
