RV Solar Installation & Power System Design
Professionally designed and installed off-grid power systems, sized to how you actually use your rig, not a generic kit. From the first load assessment through commissioning, every system we build is engineered first and installed second.
Why Solar Sizing Starts With a Conversation, Not a Catalog
A pre-packaged solar kit is sized for an average rig and an average owner — not for how you actually travel. Before any hardware gets specified, we work through how the system will really be used.
Usage Assessment
How the system needs to perform day to day.
- Nights spent off-grid vs. plugged into shore power
- What has to run when the engine and shore power are both off
- Weekend boondocking vs. full-time living
Load & Battery Sizing
Real numbers, not round ones.
- Daily amp-hour draw calculated from your actual appliances
- Battery bank sized to real usage, not a guess
- Charging sources balanced across solar, shore power, and generator
Component Selection
Hardware matched to the system, not the other way around.
- Panel wattage matched to available roof space
- Charge controller sized to actual array output
- Inverter/charger sized to peak and continuous loads
Built on a Professional Victron Component Stack
We build and commission Victron equipment as a complete, integrated system — not standalone parts wired together. Every component is selected, sized, and configured to work with the rest of the system.
Inverter/Chargers
MultiPlus and Quattro.
- Sized to your peak and continuous loads
- Installed with clean, labeled, torque-checked wiring
- Programmed and configured for your system
Solar Charging
SmartSolar MPPT controllers.
- Sized correctly to your panel output
- Configured and commissioned for your array
- Integrated with the rest of the charging system
Monitoring & Control
Cerbo GX, GX Touch, and VRM.
- Real-time state of charge and power draw
- Monitored from your phone, anywhere you have signal
- Full system visibility, not just a battery gauge
Distribution & Metering
SmartShunt and Lynx Distributor.
- Accurate battery monitoring from day one
- Clean, properly fused power distribution
- Calibrated for your specific battery bank
From Conversation to Commissioning
Every installation follows the same process, whether it’s a straightforward panel and battery upgrade or a complete 48V rebuild.
1. Load Assessment & Consultation
We start with how you actually use your rig — usage patterns, must-run loads, and travel style — before specifying any hardware.
2. System Design
For complex builds, system design is done in partnership with RV Solar Consulting to make sure the system is sized correctly the first time.
3. Professional Installation
Every connection is torque-checked, every run is fused and labeled, and the system is built to be serviceable, not just functional.
4. Commissioning & Handoff
The complete system is load-tested before we call it finished, and we walk you through the VRM app so you know how to monitor it yourself.
Backed by RV Solar Consulting’s System-Design Expertise
For complex builds, we design in partnership with RV Solar Consulting, an independent solar design partner with deep experience across hundreds of documented RV solar system designs. That partnership pairs dedicated system-design expertise with our own hands-on installation and diagnostic work, so a system is sized correctly the first time — no under-built systems that leave an owner short on power a few months later.
Frequently Asked Questions About RV Solar Installation
How do you decide what size system I need?
We start with a conversation about how you actually use your rig — nights off-grid, what has to run without shore power, and whether the goal is weekend boondocking or full-time living. That usage profile drives the load analysis and system sizing, not a pre-set package.
Can you upgrade or expand a system I already have?
Yes. We evaluate what’s already installed, determine what’s actually undersized or outdated versus what can be built on, and expand or upgrade from there rather than defaulting to a full teardown.
Do you work with lithium battery conversions?
Yes. Lithium battery bank sizing, BMS integration, and high-current DC distribution are part of every installation we design, along with converting existing lead-acid or AGM systems to lithium where it makes sense.
How long does a full installation take?
Timeline depends on system size and complexity — a straightforward panel and battery upgrade is different from a full 48V rebuild. We’ll give you a realistic timeline as part of the design conversation before work begins.
Will I be able to monitor the system myself?
Yes. Every system we build includes Victron’s Cerbo GX and the VRM app, giving you a real-time view of state of charge and power draw from your phone.
Do you install shore-power hybrid systems, or only fully off-grid?
Both. Some owners want a fully off-grid build; others want solar to supplement shore power and generator use. We design around how the RV is actually used, not a single fixed approach.
