Curated by Workshop Notes · Updated June 2026
Built for off-grid cabin owners and van builders who need a reliable 12V starter system that won't fry under heavy loads. Not for whole-house residential backup—this shop focuses on portable, stackable components for small-scale independence.
Curator's pick: Victron Energy SmartSolar MPPT 100/20 Charge Controller
This is the brain of the rig; while cheap PWM controllers exist, the Victron is the only one I trust to actually maximize harvest on cloudy days without humming or overheating. Plus, the Bluetooth monitoring saves you from having to wire in a separate, fragile display screen.
⚠ Worth knowing: The Renogy panels are sturdy, but the mounting hardware included is often too light-duty for high-wind areas or highway speeds. If you're mounting these on a vehicle roof, throw those stock Z-brackets in the scrap bin and fabricate custom steel mounts instead.

How to use this together
1
Mount and Connect Solar Panels
Begin by securely mounting your Renogy 100 Watt Solar Panel in a sunny location, oriented for maximum sun exposure. Use the iGreely 10AWG Solar Extension Cable to connect the panel to your indoor components. If expanding later, the BougeRV Solar Connectors allow for easy parallel connection of multiple panels to increase wattage.
2
Install Charge Controller and Battery
Wire the Renogy Solar Panel to the Victron Energy SmartSolar MPPT 100/20 Charge Controller, ensuring correct polarity. Next, connect the Battle Born 100Ah LiFePO4 Deep Cycle Battery to the charge controller. This order is crucial: always connect the battery to the charge controller first, and then the solar panels, to avoid voltage spikes.
