This is a complete 440W solar charging system built around two 220W bifacial rigid panels, a Victron SmartSolar 100/30 MPPT controller, and a 100Ah lithium (LiFePO4) heated house battery. It includes all mounting hardware, wiring, switches, and breakers needed to charge and protect a 12V RV house battery bank from solar.

The kit uses two 220W panels for a combined 440W of solar input. Paired with the included 100Ah lithium battery, this is generally enough to keep a moderate RV electrical load (lighting, fans, water pump, electronics, and occasional inverter use) charged through most sunny days without needing shore power or a generator.

This kit includes 2 × Lumera 12V 220W M10 Bifacial Rigid Solar Panels. Bifacial panels can capture reflected light on their backside in addition to direct sunlight on the front, which can add a modest energy boost depending on mounting height and surface reflectivity (roof color, snow, etc.).

Mounting is handled with 2 × Switch Energy Z Bracket Kits (one set per panel), which bolt to the panel frame and are then sealed and fastened to the RV roof. Z brackets create a small air gap under the panel, which helps with cooling and airflow compared to flush mounting.

This kit uses a Victron SmartSolar MPPT 100/30 charge controller, which:

• Regulates up to 30A of charging current from the panels to the battery
• Uses MPPT (Maximum Power Point Tracking) for higher charging efficiency than PWM controllers
• Includes Bluetooth monitoring via the Victron app for real-time charge status
• Supports lithium and lead-acid battery charge profiles

The kit includes a SWE LiFePO4 12V/100Ah Lithium Battery with built-in heating and Bluetooth monitoring. The internal heating element allows the battery to safely charge in cold temperatures, and Bluetooth connectivity lets you monitor state of charge and battery health from a phone app.

The kit includes several protection and disconnect components:

• IMO 4-Pole DC Switch, IP66, 32A/600VDC — for isolating the solar array
• Blue Sea Panel Mount Breaker, 40A/48VDC — protects the charge controller-to-battery wiring
• Victron 275A Battery ON/OFF Switch — allows the entire house battery bank to be fully disconnected

Together, these let you safely isolate the panels, the charge controller circuit, and the battery independently for maintenance or storage.

The kit includes pre-sized cable for both the solar array wiring and the battery connections:

• 25 ft MC4 XLPE red 10-gauge sun-resistant cable
• 25 ft MC4 XLPE black 10-gauge sun-resistant cable
• 10 AWG tinned battery cable (red and black) for controller-to-switch connections, in both bare-end and lugged terminations
• 2/0 AWG tinned battery cable (red and black) for the higher-current battery bank connections

All battery cable is tinned for corrosion resistance in RV and marine environments, and the MC4 cable is UV/sun-resistant for rooftop solar runs.

This kit is typically best suited for:

• RVs, vans, and trailers with roof space for two rigid panels
• Owners who boondock or camp off-grid and want a self-sufficient charging setup
• 12V systems that want lithium battery performance with cold-weather charging capability
• Setups that may later add engine (DC-DC) or shore charging alongside solar

Yes, this kit is designed to be DIY-friendly for anyone comfortable with basic 12V wiring. Roof penetrations for the panel brackets and cable entry should be properly sealed, and if you're unsure about wire routing, fuse/breaker sizing, or roof mounting, it's worth having a qualified RV technician or electrician review the install.

Yes. Optional add-ons include:

• Additional panels or a larger MPPT controller for higher solar capacity
• Larger or additional lithium battery banks
• Battery monitoring shunts and displays
• Combined solar + engine (DC-DC) charging bundles

Final wiring, fuse/breaker sizing, and mounting points should be reviewed against your specific RV's roof structure and electrical system, along with manufacturer guidelines. Consult a qualified installer or electrician if you're unsure about any step of the installation.
