RV & Van Power Systems: Kits, Charging & Expert Support

A complete RV or van power system has five parts working together: lithium batteries for storage, solar panels and an MPPT controller for charging, a DC-DC charger to charge from your alternator while driving, a battery monitor so you know where you stand, and correctly sized fusing and wiring to make it safe.

Access Power Solutions builds these as matched kits at three levels, backed by engineering support.

• Weekend travelers — occasional trips, lights, fridge and device charging. Start with the Weekend Ready Kit.
• Regular travelers and remote workers — longer trips, laptops, connectivity and daily off-grid use. The Road Life Kit adds capacity, alternator charging and monitoring.
• Full-timers — your van or RV is your home, and power is infrastructure. The Full-Time Freedom System is custom-reviewed around your actual loads.

Storage (a LiFePO4 battery such as a Victron 12V 100–300Ah NG), solar generation (rigid rooftop panels), charge control (a Victron SmartSolar MPPT controller sized to the array), charging from the vehicle (a Victron Orion XS DC-DC charger), monitoring (Victron BMV-702 or Cerbo GX), and protection (battery management, a battery protect disconnect, correctly rated fuses and busbars).

Component sizing follows APS engineering revision v0.2. Final solar panel and controller models are being confirmed with our vendors.

Because usage grows faster than capacity. A system sized for weekend lights and a fridge runs out of headroom once you add remote work, longer trips, or an inverter for AC loads. That is why the mid-level path adds both storage and a second charging source — solar alone is not a complete charging strategy for daily use.

Size the array from your daily watt-hours and realistic sun hours — not from how much roof you have.
