Todd breaks down how to read a Victron inverter data plate — including power factor, volts amps, and the difference between peak and continuous load. Learn why a “3000VA” inverter really gives you about 2400 watts of usable power, how load type affects performance, and how to size your inverter safely and accurately for your system.

Todd breaks down the difference between volt-amps and watts, why Victron and many generators use “volts amps” on their spec sheets, and how power factor affects what your system can actually run.

Todd walks through every piece of this powerhouse setup — showing how we achieved a true luxury off-grid system that can run three A/Cs during the day and two all night, no hookups required. If you’ve ever dreamed of living off-grid without giving up comfort, this is the setup that proves it’s possible.

Her presentation proved that the next generation of RVers is ready to power up—and take charge. Watch the full talk on YouTube!

In this episode of Todd's Two-Minute Tech Tip Tuesday, we answer a question that many RV owners face: "Why do my breakers keep tripping?" Todd explains how limited circuits in your RV—especially shared GFCI outlets—can easily overload and trip breakers, even if you're just making coffee while someone uses a hair dryer. Learn how a simple power monitor can help you understand your power usage and avoid those pesky trips.

Should you go with a 12V or 24V battery system? 🤔 From compatibility and wire thickness to inverter loads and solar controller output, Todd breaks down when 12V makes sense—and when 24V is the better choice.

We’re diving into the Victron Lynx Distribution System—a game-changer for organizing your RV solar and power setup.
