Controlador de carga solar Victron Energy BlueSolar PWM-LCD&USB 12/24V 30A

Victron Energy BlueSolar PWM-LCD&USB 12/24V 30A is a solar charge controller designed for small off-grid photovoltaic systems and vehicle installations. It supports 12V and 24V battery banks with automatic system voltage detection and provides up to 30A of charging current. The integrated LCD shows real-time information on charging status, battery voltage and settings, while the USB port allows convenient charging of portable devices. The controller combines pulse-width modulation charging with basic battery protection functions to maintain battery health and prevent overcharging.

Advantages

The device offers reliable PWM charging with automatic 12V/24V detection and a maximum continuous charge current of 30A for consistent battery management. Its built-in LCD gives clear, at-a-glance information about system voltage, battery state and charging activity. The additional USB output provides a low-power charging option for phones or accessories without affecting the main battery circuit. Compact housing and straightforward wiring make the controller suitable for installations in RVs, boats and small off-grid power systems.

Suitable for

• Small off-grid solar installations for cottages and cabins
• RVs and campervans requiring battery charge management
• Marine applications such as boats and tenders
• Backup power systems and battery maintenance setups

Key specifications

• Input type: photovoltaic (PV) panel input compatible with 12V and 24V systems
• Maximum charging current: 30A continuous
• System voltage: automatic 12V / 24V detection
• Charging method: Pulse-Width Modulation (PWM)
• Display: integrated LCD for status and settings
• Additional outputs: USB port for device charging
• Protection features: overcharge protection and basic battery monitoring

How to use

Install the BlueSolar PWM-LCD&USB controller close to the battery bank to minimise cable losses and follow safe DC wiring practices. Connect the battery first to allow the controller to detect system voltage, then connect the PV array and any loads as directed in the installation manual. Use the LCD interface to review battery voltage, charging status and adjust available settings. The USB port can be used to charge small devices directly; ensure total load does not exceed the controller's rated current.

Recommendations

Place the controller in a dry, ventilated location away from direct heat sources and protect exposed wiring with appropriate fuses or circuit breakers. For longer battery life, select the correct battery type and settings via the LCD, regularly inspect connections, and keep PV array wiring and battery terminals clean and tight.
