More power for less
With a powerful SP420 solar panel connected, you can quickly charge your battery with solar energy, meet your power needs and save money on your electricity bill in the long run.

Charge faster with 23.4% conversion rate
With a conversion rate of up to 23.4%, the F3600's 3,840 Wh battery can be fully recharged in just 2 hours and 16 minutes using four SP420 solar panels in full sunlight (under ideal conditions).
IP67 waterproof for worry-free trips
The SP420 uses a multi-layer ETFE material, which provides better light transmittance, higher efficiency and longer lifespan. The solar side of the panel is IP67 rated against splash water and is also scratch resistant.
Adjustable support legs
Quick and easy setup: Unfold the SP420 panel, adjust the angle to the sun – and you're ready to produce solar energy.

Foldable and portable
The SP420 solar panel is the ideal companion for camping or RV trips. When you're ready to go, fold the panel up and store it in your car or van.
