Victron MPPT Charge Controllers

Van Junkies stock a wide range of Victron MPPT solar charge controllers. In theMPPT model names, for example, MPPT 75/50, the first number is the maximum PV open circuit voltage. The second number, 50, is the maximum charge current.

SmartSolar charge controllers include Bluetooth for wireless communication with smartphones or tablets.

Blue Solar charge controllers do not have Bluetooth. They can be retrofitted to have Bluetooth by connecting the VE.Direct Bluetooth Smart dongle.

Sizing options:

  • Suitable for a variety of battery voltages. Most models connect to 12, 24, and 48V batteries, some only connect to 12 and 24V batteries, or only to 48V batteries.
  • Charge currents rating from 10A all the way up to 100A.
  • Maximum PV array Voc voltages ranging from 75V up to 250V.
  • Multiple chargers can be used in parallel, for large systems we recommend to use the models with a VE.Can communication port.

A solar charge controller, also known as a solar charge regulator, is a device that is used to regulate the charging of a battery from a photovoltaic (PV) panel. It is an important component of a PV system, as it ensures that the battery is charged safely and efficiently.

Solar charge controllers have several functions, including:

  1. Preventing overcharging: The controller monitors the battery's voltage and reduces the charging current from the PV panel when the battery is fully charged. This prevents the battery from being damaged by overcharging.

  2. Protecting against over-discharge: The controller also monitors the battery's voltage and disconnects the load when the battery reaches a low voltage level. This prevents the battery from being damaged by deep discharge.

  3. Maximizing power output: The controller adjusts the charging current to match the maximum power point of the PV panel, which maximizes the amount of power that the panel can generate.

Solar charge controllers are available in various types, such as pulse width modulation (PWM) controllers and maximum power point tracking (MPPT) controllers. PWM controllers are more affordable, but MPPT controllers are more efficient and can improve the overall performance of the PV system.

The Victron Energy MPPT (Maximum Power Point Tracking) charge controllers in particular are designed to optimize the charging of a battery bank from a solar array. They provide several key advantages and functionality:

  • High efficiency: MPPT charge controllers use advanced algorithms to track the maximum power point of a solar array, which allows them to extract the most power possible from the array and transfer it to the battery bank. This results in higher efficiency and faster charging times.

-Wide range of operating voltage: MPPT charge controllers can handle a wide range of input voltage from the solar panels, which allows them to work with different types of solar panels and array configurations. This makes them very flexible and can be used with different types of solar panels and configurations.

  • Automatic tracking: The MPPT controller continuously monitors the solar array voltage and adjusts its operation to follow the maximum power point of the array, which ensures that the battery bank is always charged with the most power possible.

  • Advanced monitoring and control: MPPT charge controllers can be connected to a network for remote monitoring and control, which allows you to monitor the system's performance and adjust settings as needed. This also allows you to track the solar array's power production and the battery bank's charge status.

  • Weather adaptive charging: MPPT controller adapts to the weather condition and adjust charging accordingly. So you don't have to worry about overcharging or undercharging the battery bank

  • Battery life optimization: MPPT controllers offer customizable charging profiles which optimize the battery life, providing a longer battery life.

  • Multi-stage charging : MPPT controllers have multi-stage charging, which will provide the best charge for the battery, depending on the state of charge and the environmental conditions.

-Compatible with other victron energy product: It can work seamlessly with other victron energy products such as the Multiplus inverter/charger, and GX devices for advanced monitoring and control.

Overall, Victron Energy MPPT charge controllers are a reliable and efficient option for charging a battery bank from a solar array. Their ability to track the maximum power point of a solar array and their advanced monitoring and control features make them a popular choice for off-grid and grid-tie solar power systems.
