Victron BlueSolar PWM-LCD&USB 48V-10A solar charge controller

Are you looking for a reliable solar charge controller? Then let us introduce you to the Blue Solar PWM Charge Controller LCD & USB from Victron Energy (MPN: SCC040010050)! This smart controller for battery voltages of 48 volts and 10 amps nominal charging current uses proven pulse width modulation (PWM) in combination with an advanced multi-stage charging algorithm to regulate the charging voltage. But that's not all:

Efficient battery optimization

The advanced charging process of the charge controller using PWM is fully programmable and goes through three consecutive phases: constant current, constant voltage, and charge maintenance. In the constant current phase, the battery is charged with stable current, enabling rapid energy absorption. In the constant voltage phase, the voltage is maintained at a constant level to achieve optimum battery capacity. The charge maintenance phase ensures that the battery maintains its full state of charge without overcharging. This intelligent charging strategy not only increases battery life, but also maximizes the efficiency of your solar system by ensuring that your battery is always in top condition.

Intelligent load control

Protect your battery from overcharging by connecting all loads to the load output. This automatically disconnects the loads as soon as the battery reaches a predefined voltage value. Some loads, especially inverters that are connected directly to the battery, can be optimally coupled with the load output to ensure communication between the inverter and the controller. A separate interface cable may be required for this (see manual). The day/night time setting allows you to efficiently control your lighting or other loads after sunset. In addition, the controller offers pre-programmed algorithms for various battery types such as AGM, GEL, liquid electrolyte, or LiFePO4 batteries with built-in BMS. This ensures that your battery is optimally charged and protected, while the controller can also cleverly supply devices with renewable energy via the two 5V USB outputs – a real asset to your solar system.

Additional features:

• Two 5-volt USB outputs (max. 2 A total)
• Suitable for lead-acid and LiFEPO4 batteries with integrated BMS
• Fully programmable three-stage charging
• Load output (programmable), protected against overload and short circuits
• Load shutdown at low voltage
• Reverse polarity protection for solar modules and/or battery
• Liquid crystal display (LCD)
• Programmable light control function
• Temperature protection

Comprehensive protection

The charge controller offers a comprehensive range of protective mechanisms to keep your solar system and battery safe. Integrated overcurrent protection ensures that charging currents remain within safe limits. In the event of a short circuit, the controller automatically switches off to prevent damage. In addition, reverse polarity protection protects against incorrect connection of solar modules or batteries. For battery optimization, the controller offers a three-stage charging system that divides the charging process into constant current, constant voltage, and charge maintenance. If the battery voltage is too low, the controller automatically switches off the load to prevent deep discharge. In addition, the temperature protection monitors the operating temperature and adjusts the charging strategy accordingly to extend the battery life and optimize performance.

Pulse width modulation (PWM)

Pulse width modulation (PWM) is a method of regulating electrical power that is often used in charge controllers for solar modules. With PWM control, the voltage for charging the battery is supplied in the form of rapid switching pulses. During the charging process, the duration of these pulses is adjusted depending on the current battery voltage and charge. The lower the battery voltage, the longer the pulses are in order to charge the battery with a higher current. As soon as the battery voltage approaches the desired end-of-charge voltage, the pulses are shortened to gently maintain the battery at the desired state of charge. This enables efficient and precise charging of the battery and prevents overcharging.

Crystal clear display

The liquid crystal display, also known as LCD, uses the properties of liquid crystals to modulate light and thus display clear images under a wide range of lighting conditions. Energy-efficient and high-resolution, it ensures a clear and intuitive display for real-time monitoring of the status of your solar system. You can conveniently read the charging current, battery voltage, and other important information. In addition, the screen serves as a user interface for easy setup and configuration of the charge controller. With just a few buttons, you can effortlessly navigate through the menus, adjust settings, and optimize your solar system according to your needs. This allows you to always maintain control over your energy production. The programmable light control function allows you to set the operating time of your lighting according to your individual needs, enabling energy savings and optimized use of solar power.
