When we first purchased an RV we didn’t really understand power inverters, we only knew what mattered: An inverter converts the battery power (12 Volt DC) into power that works with our electronics (110 Volt AC power). After one year on the road the charger and battery on my laptop stopped working, and thus began the tireless research to find the best power inverter for our RV. Below is my take after two years of research, conversations with dozens of service techs, and getting it straight from the “horse’s mouth” (RV mfrs. and inverter mfrs) on why we ended up with a 3000 watt pure sine wave inverter.
Let’s start where it all begins: The Factory.
When you talk to RV Manufacturers the saying goes something like this: “if you want your RV built with all the highest quality products, fit, and finish…the rig would cost $5 million!” There might be a little exaggeration there but you get the point: in general RV manufacturers cut corners and install middle-of-the-road products to save you money on the MSRP. Our Monaco Vesta came equipped with a basic 1500 watt Modified Sine Wave Inverter and charger (that’s right the charger is built into the inverter, which is not good, but I’ll save that for another post). The factory installed inverter is pretty much the “go-to” for many RV mfrs, it works fine for many circumstances, but it’s not made to run all the expensive gadgets that typically end up in an RV.
