What happened
Brazilian travelers Alessandro De Franceschi and Maria Eduarda Cardoso used a Victron Energy-based electrical system in a motorhome that connected to the grid only about three times during an approximately one-year journey through 10 African countries.S1 The installation supported two air conditioners, two refrigerators, an electric stove and Starlink satellite internet equipment in areas without conventional electricity infrastructure.S1
The system combines rooftop photovoltaic generation, three lithium batteries and charging from the motorhome’s alternator while it is moving.S1 A Victron Energy Orion DC-DC charger draws power from the vehicle during travel, while a SmartSolar MPPT 100 V/50 A controller manages photovoltaic charging.S1 The battery bank also works with a 24 V, 5,000 VA MultiPlus-II inverter, a 500 A SmartShunt, a Cerbo GX hub and a GX Touch 70 display for conversion and monitoring.S1
Each of the three batteries is rated at 25.6 V and 200 Ah, providing a combined nominal storage capacity of approximately 15.36 kWh before discharge limits and conversion losses.S1 Monitoring is available through the onboard display and remotely by smartphone, allowing the travelers to inspect battery charge and changes in solar output while the motorhome is parked.S1 The African expedition began in August 2025, and the couple also visited four countries without taking the vehicle.S1

Background timeline
XAIPART take
Technical impact
XAIPART analysis: The installation illustrates a layered off-grid architecture in which photovoltaic charging, alternator charging and lithium storage cover different operating periods. For engineers, sizing should be based on simultaneous appliance demand, usable battery capacity, conversion losses and expected solar conditions rather than nominal storage alone.
Market impact
XAIPART analysis: Mobile work vehicles, expedition platforms and remote field assets may benefit from integrated power conversion, monitoring and communications. Procurement teams should treat the battery, charger, inverter and monitoring devices as one validated architecture because compatibility between components can influence availability, installation effort and field support requirements.
Action
XAIPART analysis: Buyers evaluating similar systems should request a load profile and energy balance that includes air-conditioning, cooking, refrigeration, communications and charging loads. They should also verify usable capacity, low-voltage cutoff, alternator-isolation requirements, remote-monitoring coverage and service access before assigning costs or lead times.
XAIPART Forecast
XAIPART expects the Victron Energy-based motorhome installation to operate without a grid connection for at least 300 days within 12 months while serving a comparable daily load; if it records fewer than 300 grid-independent operating days, this forecast is wrong.XAIPART analysis
