SolarFlex Protect 220 adds a 220-watt roof panel and 30A MPPT Victron smart solar-charge controller. It is primarily designed to recharge an owner-supplied battery and operate essential 12-volt systems such as lighting, USB ports, water pumps, slide-outs, leveling equipment and compatible refrigerators. Owners can expand the system with additional solar collection, battery monitoring and inverter capability
SolarFlex Discover 440i includes 440 watts of solar collection 30A MPPT Victron smart solar-charge controller, and a 2,000-watt inverter. With an appropriately sized battery bank, it can operate the RV’s 12-volt systems and compatible 120-volt equipment such as televisions, computers, CPAP machines and smaller kitchen appliances. This package is well suited to moderate dry camping, remote work and owners who want practical household power without moving immediately into a larger lithium system. Loaded with expansion possibilities this system can easily be upgraded to 880 watts of solar collection and is prepped for an additional inverter installation to power a rooftop air conditioner.
SolarFlex Outlast 660i-L steps up to 660 watts of solar collection, a 3,000-watt hybrid inverter/charger and a heated 270Ah Dragonfly Energy lithium-ion battery. It is designed to run multiple compatible 120-volt appliances and support a soft-start air conditioner from battery power. Fast charging and advanced system monitoring make it a strong option for longer off-grid stays.
SolarFlex Magnum 880i delivers 880 watts of solar collection through four 220-watt panels, dual 30A MPPT Victron smart solar-charge controllers, a 2,000-watt inverter and Victron SmartShunt battery monitoring. With an appropriately sized owner-supplied battery bank, it can operate the RV’s 12-volt systems and compatible 120-volt equipment through up to seven inverted outlets. Dual roof ports, panel splitters and a portable-solar connection provide additional flexibility, while dedicated PV and inverter disconnects help simplify system control. Magnum 880i is well suited to owners who want increased solar collection, practical household power and longer dry-camping capability without moving into a factory-installed lithium package.

It combines 1,320 watts of solar collection, two heated 270Ah lithium-ion batteries, a 3,000-watt inverter/charger, whole-coach inverted outlets and two soft-start air conditioners. An integrated energy-management system can prioritize critical equipment when demand exceeds the available supply. The package is designed for experienced dry campers and high-demand users looking for extended boondocking capability.
SolarFlex Protect Chill combines 220 watts of solar collection with a 30A MPPT Victron smart charge controller, EM-20 Energy Management System and variable-speed air conditioning or heat-pump capability. The system is inverter-prepped with up to seven designated 120-volt outlets, giving owners a foundation that can grow as their power needs change. The EM-20 allows available power to be prioritized between the air conditioner and outlet circuit, giving owners more control over how energy is used off-grid. Protect Chill does not include a factory-installed inverter unless the RV is equipped with a residential refrigerator.
SolarFlex Discover Chill builds on that flexibility with 440 watts of solar collection, 30A MPPT Victron smart solar-charge controller, and a 2,000-watt inverter with transfer switch, up to seven inverted outlets and Victron SmartShunt battery monitoring. Its EM-20 Energy Management System allows owners to shift available power between the variable-speed air conditioner and the inverted outlet circuit based on what they need most at the moment. That makes Discover Chill especially useful for campers who want meaningful 120-volt capability while managing limited off-grid power efficiently. Power where you need it, when you need it. Loaded with expansion possibilities this system can easily be upgraded to 880 watts of solar collection.
