This week we take you inside a full Victron Energy RV solar install on an Airstream Office model — complete with 24V Epic lithium batteries, Multiplus inverter/charger, DC-DC charging from the tow vehicle, and custom fabrication to maximize space.
We walk through every step — from battery programming to running cables, installing a Cerbo GX touchscreen, and testing the system under load. You’ll see the Orion XS 1400 in action, learn about 12V-to-24V charging, and get practical tips for cooling electronics compartments.
Whether you’re upgrading your RV, planning an Airstream build, or just curious about off-grid Victron setups, you’ll find plenty of real-world advice in this install.
