A coffee maker or a toaster will surprise you in that they have very high power consumption demands. They will consume anything from 800 watts up to 1500 watts or more. What you need to do when you are setting up your system is look at the devices that you are going to be powering. Then get the inverter that will be large enough to power your needs and wants.
This is our DIY electrical power. Pick up the bin (carefully, it’s heavy) and put it in your trailer, pickup truck, van, or car and you can haul electricity along with you. If you have an RV, then adding an inverter to your existing battery array will provide you with AC power in addition to DC power. Will everyone want a system like this – probably not. Can you purchase an inexpensive generator for about the same amount? Yes. There are times that a system like this will be exactly what you want. Next, we need to get a solar panel so that we are truly off the grid.
