Dometic SMART-IN 12V 400W Inverter - Pure Sine Wave
The Dometic SMART-IN 12V 400W Inverter converts power from your 12V leisure battery into a clean 230V pure sine wave supply, making it ideal for running electronics while travelling or living off-grid.
Compact, efficient and designed for reliable operation, the SMART-IN 400W is well suited to campervans, motorhomes and other mobile installations where you need dependable mains power without excessive battery consumption. Its pure sine wave output closely replicates the power supplied by a household socket, making it suitable for powering a laptop, games console or camera battery charger.
Efficient off-grid power
The SMART-IN offers an energy yield of up to 93%, helping you make efficient use of the energy stored in your leisure battery. Its low self-consumption also reduces the amount of power used by the inverter itself, helping preserve battery capacity when you're off-grid.
Professional connectors help minimise voltage drop and unnecessary power losses, reducing battery consumption and improving overall efficiency.
Compact and easy to install
Integrated mounting brackets make the inverter straightforward to secure within your electrical installation. Its 400W format makes it useful wherever you need a dependable 230V supply from a 12V battery bank.
The inverter is also ready for remote ON/OFF control, allowing it to be controlled from a more convenient location if installed out of sight.
Built-in protection
The Dometic SMART-IN includes a range of protection features designed to safeguard both the inverter and your electrical system:
- Soft start protection
- Overload protection
- Short-circuit protection
- Reverse polarity protection
- Overheat protection
- Low battery alert
Pure sine wave explained
A pure sine wave inverter produces a smooth AC waveform similar to the electricity supplied by a normal household socket. This provides broad compatibility with electronic equipment and helps ensure reliable operation.
While modified sine wave inverters can be suitable for simpler loads, pure sine wave models provide broader compatibility and are generally the better choice for electronics such as laptops, chargers and other equipment containing electronic power supplies.
