Power inverter Voltcraft SW-150 24V 150 W 24 V DC to 230 V AC, fanless

The Voltcraft SW-150 24V is a compact, fanless power inverter that converts 24 V DC to 230 V AC with a continuous output of 150 W. Designed for quiet operation and minimal space usage, it enables powering small household appliances, chargers and electronic devices from 24 V battery systems commonly found in vehicles, boats and off-grid installations. Built-in overload and short-circuit protection help maintain safe operation under variable loads.

Advantages

The fanless design provides silent operation and reduces maintenance by eliminating moving parts. Its compact casing and straightforward DC input make installation simple in confined spaces. Thermal and electrical protection functions guard connected equipment against overloads and short circuits, while the stable AC output ensures compatibility with typical low-power devices and chargers.

Suitable for

• Powering laptop chargers, phone chargers and small electronic devices
• Running low-power household appliances such as small fans or LED lights
• Use in vehicles, caravans, motorhomes and boats with 24 V battery systems
• Off-grid or temporary installations where quiet, compact power conversion is required

Key specifications

• DC input voltage: 24 V
• AC output voltage: 230 V
• Continuous output power: 150 W
• Design: fanless (convection cooled)
• Protection features: overload protection, short-circuit protection, thermal protection
• Output waveform: modified sine / suitable for resistive and many electronic loads
• Compact dimensions and low weight for easy installation

How to use

Connect the inverter to a properly sized 24 V DC battery or power source following the polarity markings on the input terminals. Place the unit on a stable, well-ventilated surface to allow passive cooling and avoid covering the housing. Plug the AC device into the inverter’s 230 V output socket and switch the inverter on. Monitor the total power draw to ensure it does not exceed the continuous 150 W rating; if the inverter detects overload or a short circuit it will shut down or limit output until the fault is removed.

Recommendations

For reliable operation, use the Voltcraft SW-150 24V with devices whose combined power draw stays below 150 W and avoid inductive loads with high startup currents. Ensure battery capacity and cabling are adequate for the expected load and keep the inverter away from direct moisture and heat sources.
