When people start upgrading their RV electrical systems—especially when stepping into the world of dual inverters, full-time boondocking, or large solar arrays—there comes a moment where the equipment they’ve added still doesn’t quite deliver the seamless experience they expected. You may have the battery bank, the solar, the inverters, and the monitoring dialed in, yet a single stubborn question remains: “Why am I overloading one inverter when I have two?” This is where the

Welcome back to Todd’s Two-Minute Tech Tip Tuesday , brought to you by Big Beard Battery —your go-to source for off-grid lithium power and RV solar systems. In this session, Todd answers three of the most common questions RV owners ask about DC-to-DC charging , battery storage voltage , and solar maintenance during winter . Whether you’re driving across the country or parking your rig for the season, understanding these fundamentals can make the difference between a smooth st

Stepping Down 24V to 12V the Right Way When upgrading your RV to a 24-volt lithium battery system , one of the most common questions we get at Big Beard Battery  is: “If I switch to 24 volts, how do I still power my 12V lights, fans, and accessories?” It’s a great question—and one that comes up often as more RV owners make the jump to higher-voltage systems for efficiency, faster charging, and cleaner power management. The good news is: you can have both. With the right DC-DC

In this video, Chris shares his experience at the Big Beard Battery Solar Clinic, where he installed a powerhouse RV system — featuring 4,300 watts of solar, three 24V 300Ah “The Beast” batteries, and dual Victron 3000W inverters.

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.

If you’ve ever installed or expanded your RV solar system, you’ve probably realized that finding the right length of solar cable  can be a challenge. Instead of buying pre-cut cables that may be too long or too short, you can easily make your own custom PV solar cables  using MC4 connectors . In this week’s Todd’s Two-Minute Tech Tip Tuesday , brought to you by Big Beard Battery , Todd Henson walks through how to build your own PV cable step-by-step — saving you time, money,
