  Product Description
The Dometic SinePower DPSI 3012TS is a 3000W pure sine wave inverter designed for motorhomes, caravans, and campervans where multiple high-power appliances need to run simultaneously. This 12V to 230V inverter delivers clean, stable power for sensitive electronics like laptops, TVs, and kitchen appliances. The compact design measures 445 x 255 x 87mm and weighs 5.1kg, taking up less space than comparable inverters on the market.

The integrated mains priority switch automatically detects when shore power becomes available and switches your electrical system from battery power to mains supply. This intelligent feature preserves your leisure battery life by prioritising external power sources when connected to a campsite or charging point. The transfer switch eliminates manual switching between power sources and prevents backflow, protecting your electrical system.

The inverter connects to Dometic's N-BUS and CI-BUS systems for straightforward installation in existing motorhome electrical setups. You get three control options: manage power consumption through the Dometic TD283 wall display, the Dometic Power app on your smartphone, or the included remote control. The low-profile housing includes integrated mounting brackets, making installation simpler than inverters requiring separate mounting hardware.

Frequently Asked Questions

What does the transfer switch do on the Dometic DPSI 3012TS inverter?
The integrated transfer switch automatically detects when mains power from a campsite hookup or charging point becomes available and switches your motorhome's electrical system from battery inverter power to shore power. This automatic changeover preserves your leisure battery life by prioritising external power sources, eliminates the need for manual switching, and prevents electrical backflow that could damage your system.
What appliances can run on a 3000W pure sine wave inverter?
A 3000W inverter handles most motorhome appliances including microwaves, coffee machines, hair dryers, laptops, TVs, phone chargers, and small kitchen appliances simultaneously. Pure sine wave output is essential for sensitive electronics, appliances with motors, and devices with digital displays. The DPSI 3012TS provides 3300W maximum output for one minute and 5700W surge power for one second to handle appliance startup loads.
How do I control and monitor the Dometic SinePower DPSI 3012TS?
You have three control options for the DPSI 3012TS. The Dometic Power app provides smartphone control and real-time energy consumption monitoring from anywhere in your vehicle. The Dometic TD283 wall display mounts inside your motorhome for quick status checks and control. The included remote control offers basic on/off functionality and comes with a connection cable. All three methods show accurate consumption data to help manage your battery power efficiently.
What is the difference between pure sine wave and modified sine wave inverters?
Pure sine wave inverters like the Dometic DPSI 3012TS produce smooth AC power identical to mains electricity, making them compatible with all appliances including sensitive electronics, devices with motors, and equipment with digital displays. Modified sine wave inverters produce stepped output that causes buzzing in audio equipment, shorter appliance lifespan, reduced efficiency, and incompatibility with medical equipment, laser printers, and variable speed tools. Pure sine wave technology is essential for modern motorhome electrical systems.
What size leisure battery do I need for a 3000W inverter?
The DPSI 3012TS draws approximately 250A from a 12V battery at full 3000W load. For short-term high-power use, a 200Ah lithium leisure battery provides around 40 minutes at full load, while 400Ah gives 80 minutes. Lead-acid batteries should only be discharged to 50 percent, so double these capacities for comparable runtime. Most motorhome users run lower wattage appliances intermittently rather than continuously at maximum load, extending battery life considerably. The transfer switch feature helps by automatically switching to mains power when available.
