Victron DC-DC Chargers

Victron Energy DC-DC chargers, the reliable and efficient solution for all your battery charging needs.

Firstly allow us to explain the difference between a DC-DC charger
and a DC-DC converter:

While both Victron DC-DC chargers and DC-DC converters serve a similar purpose of converting DC power, there are some key differences between the two.

A DC-DC charger is specifically designed to convert DC power from a source such as a vehicle's alternator or battery into a regulated and controlled charge for another battery system, such as in a "Dual Battery" setup . It ensures efficient charging of batteries by adjusting the voltage and current based on the battery type and condition. DC-DC chargers also often include additional features like battery temperature sensing and intelligent charging algorithms to optimise battery lifespan and performance.

On the other hand, whilst some models ARE suitable for charging duties, a DC-DC converter is more versatile and used for converting DC power to a different voltage level to cater to various devices or systems. It allows you to step up or step down the voltage, depending on the requirements of your load.
DC-DC converters are commonly used in applications such as powering appliances or equipment in vehicles, boats or off-grid installations. They provide a consistent and stable power supply, ensuring proper functioning of the connected devices.

In summary, whilst a Victron DC-DC charger is specifically designed for efficient battery charging, a DC-DC converter offers voltage transformation for powering devices or systems with different voltage requirements.

Why choose Victron DC-DC Chargers?

Whether you're looking to power your marine applications or optimise your automotive systems, our range of Victron isolated and non-isolated DC to DC chargers provides the flexibility and performance you require. Choose Victron for advanced charging technology that keeps your batteries performing at their best.

Here are a few reasons why Victron doesn't include a Solar Charge Controllers in their DC DC Chargers:

1. The DC to DC charger can remain cheaper.
2. Solar can be charging into the battery system simultaneously with the on-board vehicle charging.
3. You can purchase the correct solar regulator to match your solar panels, which will provide the best efficiency for solar charging.

The difference between isolated and non-isolated Victron DC to DC chargers.

An isolated DC-DC charger has one negative connection for each battery and there is no internal connection between the negatives. They are required for systems that need to be isolated, which could be for a number of reasons including limiting corrosion (typically marine applications) and preventing noise on one battery system from affecting the other battery system.

For systems that do not require isolation, either unit can be used. However, the non-isolated unit is cheaper and requires one less wire to be installed. In automotive systems, the negative of both batteries is typically connected to the chassis of the vehicle. This is a non-isolated system; therefore, either unit will be suitable. Caravan, RV, and 4X4 customers tend to purchase non-isolated Victron DC to DC chargers, with the most popular being the 30A 12/12 DC to DC charger.

What is a "Smart" DC to DC Charger?

The term "Smart" refers to Victron's ability to connect your Bluetooth device (Smartphone) to their DC to DC Charger via the Victron Connect APP. This allows you to monitor and make setting changes easily. It's a unique feature of Victron energy systems. The VictronConnect App is available in App Store, Google Play, Mac app, and Download for Windows.
