SolarFlex Discover 440i: Off-Grid Power Solution for 2024 Keystone RV Models

New for 2024! Keystone's SolarFlex Discover 440i offers everything RV owners need to venture off the grid. With two solar panels and a 2000W inverter, this system powers both 12V systems and seven compatible 110V outlets. While it’s not designed for endless energy supply, it provides ample power to extend your adventures off-grid, making it a robust and economical solution for moderate energy needs.

SolarFlex Discover 440i Components

The SolarFlex Discover 440i components work together to give you control over your energy supply while providing critical real-time power monitoring via the VictronConnect app.

What You Can Expect

SolarFlex Discover 440i introduces many of the conveniences of shore power, enabling you to run 110V electronics up to 2000 watts, such as small kitchen appliances, CPAP machines, computers, and entertainment systems. With a 440-watt solar array, this system doubles the energy capture and charge rate of the SolarFlex Protect 220. When paired with appropriate batteries and sunny conditions, SolarFlex Discover 440i makes dry camping a viable option.

Real-time battery monitoring through the Victron SmartShunt allows you to track power draw, remaining charge, and more via the VictronConnect app. This helps you manage your energy use and extend your time away from shore power or a generator.

Grow Your System for Greater Boondocking Adventures

SolarFlex Discover 440i is designed for easy expansion. It features a second roof port and prep for an additional charge controller, plus a soft-start AC prep, allowing for serious off-grid camping in the future. Adding a second inverter and appropriate air conditioner will significantly increase your system’s capabilities.**
