System and Component Functionality
Expandable battery bank Our system can support 2-4 Victron 200ah Smart Lithium Batteries giving you between 400ah-800ah of energy storage. These batteries are superior to competitors for the following reasons:
High energy density: Victron Smart Lithium Batteries have the same energy density as most 100ah drop in batteries, meaning you get double the power for the same footprint.
Communication with the system: Using a physical connection to the Battery Management System (BMS) allows for closed loop communication. The BMS takes control of the system for greater efficiency and safety.
Bluetooth connectivity: The Victron Connect app gives you warnings and updates about battery health in real time.
Superior discharge current: The Victron 200ah Smart Lithium batteries can discharge at 400 continuous amps allowing you to support large DC loads and inverters.
A Victron 3000VA Hybrid Inverter Charger gives you the ability to power an induction cookstove, air conditioner, tools and more while off-grid. When you are plugged into shore power, it also allows you the ability to charge your battery bank.
A 50 amp Solar Charge Controller allows for up to 640 watts of solar on your camper.
60 amps of DC-DC charging from the alternator provides additional power to the batteries.
16 dedicated DC circuits to supply power to loads such as your fridge, heating system, lights, usb ports and more!
4 dedicated AC circuits including a 20 amp breaker for high loads such as an induction cookstove or an A/C unit.
Full monitoring via the Victron Connect app as well as the Cerbo and Touch GX touch screen provides you with the information to make educated decisions. You can also add auxiliary sensors for temperature and water tank level.
Alternator upgrade option with a pre wired and programmed Wakespeed alternator regulator installed in the box to work with a Nations Starter and Alternator 280 amp dedicated secondary alternator. See below for details on this upgrade.

Upon arrival, you will need to connect positive and negative lines to the batteries, make your solar, alternator and shore power connections and then crimp on your AC and DC loads.
Maintenance: fully charge your batteries every 2-4 weeks allowing for cell rebalancing. If leaving for an extended period of time turn off your DC loads via the dedicated breaker and switch inverter to charger only mode with it plugged into shore power. Make sure that the AC current limit is set to 13 amps.
