People are asking

What is a pure sine wave inverter and why does it matter?

A pure sine wave inverter produces clean AC power identical to the power from a household wall socket. This is important for sensitive electronics like laptops, phone chargers, medical equipment, and appliances with motors. Modified sine wave inverters are cheaper but can damage or reduce the lifespan of these devices.

What size inverter do I need for my campervan?

Match the inverter wattage to your highest-draw appliance. The MSI-412 (400W) suits laptops and small appliances. The MSI-912 (900W) handles a microwave, electric blanket, or hair dryer. The MSI-1812T (1800W) covers kettles, toasters, and most 240V appliances. Always factor in surge draw at startup for motor-driven appliances.

How do I wire a Dometic inverter to my campervan battery?

Dometic inverters connect directly to your 12V battery bank using heavy gauge cable — typically 25-50mm² depending on the inverter size and cable run length. Always fuse the connection close to the battery using an ANS or ANM fuse of the appropriate rating. Vanlifer can assist with electrical planning if needed.
