Victron Energy SolidSwitch 104

The Victron Energy SolidSwitch 104 Lets a Low Power Digital Signal Switch Your DC Loads

The Victron Energy SolidSwitch 104 is a compact DC load switch that turns loads of up to 70V and 4A on and off from a low power digital signal. If you build or maintain battery-based power systems for RVs, off-grid cabins, boats, or mobile work rigs, you have probably wished a small control signal could do the job of a hand-operated switch. That is what this little module is for. It is also a handy way to switch a contactor coil, so a tiny signal can end up controlling a much bigger circuit.

It weighs about 0.1 lbs and measures roughly 3 x 3 x 2 inches, so it will not take over your electrical bay. Outbound Power carries the Victron SolidSwitch 104 for installers, DIY system builders, and anyone who wants a controllable DC switch in a Victron-based setup.

Victron Energy SolidSwitch 104 Features

70V and 4A Switching Capacity For Controlling Real DC Loads

The SolidSwitch 104 is rated to switch DC loads of up to 70V and 4A. That covers a wide range of small DC loads and control circuits. Do the math on your own load before you buy, since 4A is the ceiling.

• Switches DC loads up to 70V
• Switches loads up to 4A
• Designed for DC loads, so confirm your load type before ordering

Digital Signal Control So You Can Automate Instead Of Flipping Switches

This switch is controlled by a low power digital signal. A controller or monitoring device can command the switch, and nobody has to walk out to the battery bay with a flashlight. The datasheet for the SolidSwitch 104 is available from the manufacturer, and we recommend checking it to confirm that the signal from your control device is compatible.

Resistive, Capacitive, And Inductive Load Support For More Flexible Projects

The DC load can be resistive, capacitive, or inductive. The manufacturer gives the coil of a high-power contactor as an example of an inductive load. In practice, a small switch like this can be the go-between that lets a low power signal operate a heavy-duty contactor, which in turn handles the serious current.

Compact Size For Tight Installations

At roughly 3 x 3 x 2 inches and 0.1 lbs, the SolidSwitch 104 is easy to fit into a crowded enclosure or equipment compartment. Please review the manufacturer's dimensions drawing before you plan a mounting location.

Clear Protection Limits So You Can Design Around Them

Good design starts with knowing what a part will not do. The SolidSwitch 104 is not reverse polarity protected and is not short circuit proof. Plan on proper fusing and careful, correct wiring in your system. Think of it as a precise tool that rewards careful installation.

Real-World Applications

The SolidSwitch 104 is a building block, not a standalone power system. Here are situations where a digitally controlled DC switch may make sense, provided your load stays within 70V and 4A.

• RV and camper systems. Switch a small DC circuit or contactor coil from a control signal.
• Off-grid homes and cabins. Use a controller to switch a DC load on or off without a trip to the battery room.
• Marine and boat builds. Control a small DC circuit remotely. Confirm the installation environment suits the product first.
• Mobile worksites and service vehicles. Operate auxiliary DC loads from a central control point.
• Custom battery and monitoring projects. Let a low power digital output drive a contactor coil that handles larger loads.

How The SolidSwitch 104 Compares To Other Options

A standard manual toggle or rocker switch works well when someone is standing right there to operate it. The SolidSwitch 104 is a better match when a digital signal needs to do the switching, such as when a controller is managing a load automatically or remotely.

It also differs from a high-power contactor. A contactor is built to carry heavier current, while the SolidSwitch 104 tops out at 4A. The two can work as a team, because the SolidSwitch 104 can switch the contactor's coil. Make sure the specifications of each component in your design line up.

Is The Victron SolidSwitch 104 Right For You

This is a specialist component. It is best suited to installers, system designers, and confident DIYers who already know what they want to control and how it will be signaled.

This may be a good fit if:

• You need to switch a DC load of up to 70V and 4A.
• You have a low power digital signal available to control it.
• You want to drive the coil of a larger contactor.
• You are comfortable adding your own fusing and protection.

Before you buy, confirm that your control signal is compatible, that your load is DC, and that it stays within the voltage and current rating. Remember that the SolidSwitch 104 has no reverse polarity protection or short circuit protection. If you are unsure, the Outbound Power team is happy to help you think it through.

Common Questions

What is the maximum load the SolidSwitch 104 can switch?
The manufacturer rates it for DC loads of up to 70V and 4A.

How is the SolidSwitch 104 controlled?
It is controlled by a low power digital signal. Check the manufacturer datasheet to confirm that your control device is compatible.

Can it switch inductive loads like a contactor coil?
Yes. The load can be resistive, capacitive, or inductive, such as the coil of a high-power contactor.

Is the SolidSwitch 104 protected against reverse polarity or short circuits?
No. It is not reverse polarity protected and not short circuit proof, so wire it carefully and protect the circuit appropriately.

Will it switch AC loads?
The product information describes switching DC loads. Please confirm any other use with the manufacturer before purchase.
