Victron 12 volt Inverters

What Size Inverter Do I Need? 

The size you need depends on the total wattage of the devices you plan to run at the same time. Add up the wattage of each device and choose an inverter that exceeds that total. As a rule of thumb, add 20-25% on top to give yourself headroom for startup surges. 

Some appliances, like fridges and power tools, draw a higher wattage when they first switch on. That surge can be two to three times the running wattage, so your inverter needs to handle it without tripping. 

What Can a 12V Inverter Run? 

A 12V inverter can run most standard household devices, but the key factor is wattage. Low-draw devices like laptops, phone chargers and LED lights are well within range. Higher-draw appliances like kettles and microwaves need a larger inverter, typically 1,500W or above. 

Why Are There Large Differences in Price for the 12V Inverters? 

Price differences come down to output power, build quality and extra features. A 300-watt continuous output costs less than a 3,000-watt continuous output unit because it’s designed to handle more. A smart inverter with Bluetooth monitoring, a handy feature, will naturally cost more than a unit without one. 

How Much Power Do I Need? 

The amount of power you need depends on which devices you plan to run and for how long. Add up the wattage of everything you want to use at the same time, and that gives you your minimum inverter size. From there, build in some extra capacity for peace of mind. 

A laptop typically draws 45W to 100W. A small television sits around 80W to 150W. A kettle, on the other hand, can pull 2,000W or more, so one high-draw appliance can change your requirements entirely. 

Think about your typical day. If you're charging devices and running lights, a 500W to 800W inverter covers most needs. If you're cooking, running a fridge and watching television, you're looking at 1,500W or above.
