Why This System Works
- True plug-and-play — solar panel connects directly to the Lithium1200 via the FlexoLink cable. No wiring, no separate controller, no setup.
- 400W solar input delivers maximum daily harvest — ideal for high-consumption setups.
- Built-in MPPT in the Lithium1200 maximises solar harvest automatically.
- Power Boost extends AC output from 1200W to 1600W for heavier appliances.
- 15m cable means panel in the sun, power station in the shade — better for both performance and longevity.
- Tilt legs angle the panel at 45° for optimal performance in winter or early and late sunlight.
- Mounting bracket keeps the Lithium1200 secure while driving — no movement, no damage on rough terrain.
- Every component is individually warranted and supported by Flexopower directly.
Mobile Dual Battery System — With the FlexoDrive DC-DC Unit
The Lithium1200 in this kit becomes a complete vehicle-based Mobile Dual Battery System when paired with the FlexoDrive DC-DC unit, installed by a qualified Flexopower installer. The DC-DC unit manages alternator charging intelligently at 320W — protecting your vehicle's battery while delivering consistent charge to the Lithium1200 while you drive. Engine On / Off Auto Sense detects when the engine starts and stops, automatically beginning and ending the charge cycle without any manual intervention. Monitor and control the system via the FlexoApp.
Unlike a fixed dual-battery installation, the Lithium1200 moves with you — between vehicles, trailers, camp and home. Your power investment is not locked into one vehicle.
The FlexoDrive DC-DC unit is available through our qualified installer network only — not sold direct. Contact us to find a Flexopower installer near you.
