What We Do
Permanent, professional solar systems for RVs, travel trailers, and off-grid builds — designed for how you actually use them.
Our Services
Full RV Solar System Design & Installation
The complete package — from load assessment and system sizing through final commissioning and walkthrough. We use Victron Energy components throughout: MPPT charge controllers, MultiPlus inverter/chargers, Lynx power distribution, Cerbo GX monitoring, and lithium battery banks sized for your actual power needs.
Every system is custom-designed for your specific rig and lifestyle. A full-timer with a Class A who wants to run the AC off solar has very different needs than a weekend boondocker with a travel trailer. We size and spec accordingly.
Best for: Full-time RVers, dedicated boondockers, anyone ready to stop depending on shore power.
Lithium Battery Upgrades
Upgrading from AGM or lead-acid to lithium is one of the highest-impact improvements you can make to an existing system. Lithium batteries charge faster, discharge deeper, weigh less, and last significantly longer than older battery chemistries. We handle the full upgrade — battery selection, BMS integration, and ensuring your existing charge sources are properly configured for lithium.
Best for: RV owners with an existing system who want better performance and longer battery life.
System Assessment & Consulting
Not sure what your system needs? We’ll assess your current setup, identify weak points, and give you an honest picture of what it would take to get where you want to be. No upsells — just a straight answer about your system.
Available in-person for customers in San Antonio and surrounding areas, and remotely for customers across Texas.
Best for: RV owners troubleshooting an existing system, or anyone planning a future build and wanting professional input.
Off-Grid & Tiny Home Solar
The same principles that make a great RV solar system apply to tiny homes, cabins, and other off-grid structures. We design and install Victron-based systems for permanent off-grid living — sized for your load, built to last, and designed to give you real energy independence.
Best for: Tiny home owners, cabin builders, and anyone establishing a permanent off-grid power system.
Why We Use Victron Energy
We spec Victron Energy components on virtually every build. Victron is the choice of serious full-timers, live-aboard boaters, and professional installers worldwide — not because it’s the cheapest option, but because it’s the most reliable, most expandable, and best-supported system available.
Victron’s VRM monitoring platform lets you check your system from anywhere in the world. Components communicate with each other. Software updates are free. And when something needs troubleshooting, there’s a massive community of experienced users and dealers who know these systems inside and out.
We’re an RVTAA certified installer with specialized Victron training, which means we know these systems at a level beyond reading the manual.
Not Sure What You Need?
That’s what the consultation is for. Tell us about your rig and how you use it, and we’ll tell you exactly what we’d recommend — and why. No commitment required.
