RV POWER ACCESSORIES
Enhance your RV electrical system with battery monitoring and charging management accessories from Victron.
CHARGING MANAGEMENT
Improve battery charging accuracy with precise battery voltage and temperature measurements. This information helps compatible charging equipment optimize battery charging and support proper battery management.
Particularly recommended when the MPPT charge controller and battery bank are installed in different locations, where cable voltage drop and temperature differences can affect charging performance.

BATTERY MONITORING WITH DISPLAY
View battery voltage, charge and discharge current, state of charge, consumed amp-hours (Ah), and estimated time remaining.
Track historical battery performance, including deepest discharge, average discharge, and the number of charge/discharge cycles.
Includes a measurement shunt and a dedicated physical battery display.

DISPLAY-FREE BATTERY MONITORING
Provides similar battery monitoring features to the BMV-712, but without a separate physical display. Your phone acts as the display through the VictronConnect app.
According to the supplied engineering information, monitoring data can be stored for up to 46 days. This is a practical option when less wiring and clutter are preferred.

440W RV Solar Power Kit FAQ
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:
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:
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:
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:
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:
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.
