Product Features - Projecta SC420/ND Manual

2. Product Features

• 4 Stage charging ensures the battery is charged to the optimum level
• Advanced MPPT technology to improve charging efficiency in different weather
and temperature conditions
• Tempered glass cover with screen touch operation and sturdy aluminium housing
• Selectable battery chemistry types, including AGM, GEL, WET and Lithium
• Auto recognition of 12V/24V battery system voltage
• Protects your battery from discharge at night. Under low light or no light conditions, the solar panel
voltage could be less than the battery voltage. The controller contains circuitry which prevents current
flowing back from the battery and into the solar panel
• Multi charging protections against reverse polarity, over-voltage and over-temperature.
• With the use of a battery temperature sensor (optional), the controller will compensate charging
voltages when the battery temperature becomes too high (For Lead acid only).
• Supports remote display for monitoring additional parameters, such as charging watt-hours,
charging current and solar input voltage.
