When Garrett signed up for the Big Beard Battery Solar Clinic, he wasn’t exactly sure what he was getting into—but he knew one thing: he wanted off-grid power without the fear of messing it up.
What he got was more than just a solar and lithium install. He got hands-on education, expert guidance, and the confidence to take full control of his RV power system.
🛠 Learning By Doing
In the video, Garrett shares how he arrived at the clinic unsure about how all the components—solar panels, charge controllers, lithium batteries, inverters, and monitors—fit together. But by the end of the week, he had installed a complete RV solar lithium power system himself… and understood every part of it.
He didn’t just plug and play—he learned:
How to wire solar panels correctly and safely
Why fusing and cable sizing matters
How to configure Victron gear for efficient, off-grid performance
The ins and outs of shunt-based battery monitoring
Best practices for mounting, airflow, and battery health
🤝 Expert Support, Not Just Supervision
What really stood out to Garrett was the balance of independence and support. The Big Beard Battery team didn’t just tell him what to do—they walked beside him, offering guidance when needed, and stepping back so he could learn through experience.
As Garrett puts it, “They let me build it, but they made sure I did it right.”
🏝 It’s Not Just a Clinic—It’s a Texas Experience
Garrett also shares a few unexpected highlights from the experience—like relaxing in the resort-style pool, swapping stories with other RVers, and capping off the week with homemade brisket from Todd Henson himself.
It’s clear that the Solar Clinic isn’t just a training—it’s a full-on off-grid lifestyle immersion, complete with southern hospitality and serious know-how.
🔋 A Fully Functional, DIY Lithium Power System
By the time Garrett rolled out, his RV was upgraded with a custom-designed DIY solar lithium system, capable of running everything he needs while boondocking—without the hum of a generator or fear of running out of juice.
And better yet, he knew how to use it, maintain it, and expand it in the future.
