How to Add More Solar Panels to an Existing RV Solar System

Many RVs come from the factory with a small solar system, but what happens when you want to add more solar panels? In this video, I walk through the process of expanding an existing RV solar system and explain the key factors that determine whether your upgrade will work efficiently. We'll cover how to wire additional panels in series, parallel, and series-parallel configurations. I'll also discuss the challenges of mixing solar panels with different VMP operating voltages and explain when upgrading from a PWM charge controller to an MPPT charge controller becomes necessary. If you're planning to expand your RV solar system, this video will help you avoid common mistakes and maximize charging performance. 🔗 PRODUCTS & GEAR USED IN THIS BUILD Solar Panels → https://amzn.to/3S2Q8Jz Victron MPPT Charge Controller → https://amzn.to/4xjg2c5 Solar Parallel Connector → https://amzn.to/4gdMIO2 MC4 Connectors → https://amzn.to/4utIDcc Battery Monitor / SmartShunt → https://amzn.to/3QxDfH3 DC Circuit Breakers → https://amzn.to/3RTL2iV Bus Bars → https://amzn.to/4eBtnVU Solar Panel Feet → https://amzn.to/4oqMR2S 🧰 Tools Used Digital Multimeter → https://amzn.to/3S74ecU MC4 Crimp Tool Kit→ https://amzn.to/4omRlaP Wire Crimper → https://amzn.to/4v4okD3 Wire stripper → https://amzn.to/4vHRBn9 Heat Shrink Torch → https://amzn.to/4olRICx Some of the links in this description may be affiliate links.
