LIBERGRID RV power system
TBB’s modular system for vans, motorhomes and work vehicles: a PH inverter charger, DC-DC and solar charging, M12 lithium and one monitor.
LIBERGRID is designed for converters, installers and owners fitting out a vehicle. At its centre is a PH inverter charger, which runs your 230V appliances and charges the battery from shore power. A DDN charger adds charge from the alternator while you drive and from solar when you stop, and an M12 lithium battery stores it all.
Everything reports to the LIBER43 touchscreen, which shows charge, solar input and power use, and switches the battery on and off. It connects to TBB’s apps over Bluetooth and Wi-Fi for monitoring and remote support.
In place of the DDN, an SN solar controller with a DN DC-DC charger suits vehicles with more solar. The D11 adds digital control of lighting, pumps and tank sensors.
Features
- Start with the parts you need and add more later, with every part designed to work together.
- Power assist tops up a weak campground supply from the battery, and power control stops the site breaker tripping.
- Runs an air conditioner, microwave and coffee machine on 230V, with twice the rated power for start-up surges.
- Charges from shore power, the alternator and solar, and the batteries warm themselves before charging in the cold.
- The LIBER43 screen shows the whole system and switches the battery, with Wi-Fi and optional 4G for remote monitoring.
- Four main components do the work of around ten in a typical setup: LIBER43, M12-230, PH3.0L and DDN1245.
