You shouldn't need a phone, a tablet, and three different apps just to check your RV battery. Juggling multiple displays and tiny screens? Not anymore.

LIBER43 is the centralized display of the LIERGRID system. One 4.3-inch HD touchscreen gives you real-time visibility of every component — battery SOC, inverter status, solar input, and DC-DC charging — all in one place. With physical rotary control and built-in Bluetooth, true one-screen control is finally here.

Whether you're on weekend trip or full-time off-grid adventures, LIBER43 puts complete system visibility and effortless command right at your fingertips.

See Everything at a Glance

LIBER43's crisp screen shows you exactly what's happening with your entire RV power system — instantly and clearly.

See your battery level, how much time you have left, and all charging sources — shore power/generator, alternator, and solar — all at a single glance. No guessing, no switching between devices.

One simple tap on any module on the Home screen takes you straight into detailed insights for the battery, inverter charger, solar charger, or ALT charger.

Plug-and-Play Setup

Power on LIBER43 and it automatically recognizes every connected LIERGRID component. The System Configuration page instantly displays the exact number of devices connected. Confirm once and your system is ready — no manual entry required. Add new modules later? LIBER43 automatically detects and updates the overview with one tap.

One Knob. Two Taps. Total Control.

Twist the rotary knob to turn your entire RV power system ON or OFF — works instantly even with gloves on, or in the dark. No app, no extra switches are required. Two touch buttons right above and below the knob give you one-tap access to programmable functions like inverter output on/off. Effortless, reliable control at your fingertips — every single time.

Built-in Bluetooth: Connect to Two Powerful Apps

LIBER43 features built-in Bluetooth that communicates seamlessly with two dedicated TBB apps — one for real-time monitoring, one for instant service support.

TBB Connection App — Local Monitoring

Mirrors the LIBER43 screen on your phone in real time. View all system data, adjust settings, or control functions anywhere inside the RV. No need to walk to the screen. Also supports OTA firmware upgrades for the display itself.

TBB Service App — One-Tap Support and remote diagnostics

Encounter an issue on the road? Open the app and tap “Submit Issue”. Describe the problem briefly. The App instantly uploads system logs, firmware version, and component status. Our engineers receive the ticket immediately and can provide remote guidance or direct resolution. Track everything in the Issue List.

System Settings, Simplified

Make your power system work exactly the way you live and travel — whether you're weekend camping, hitting the open road, or living full-time off-grid.

With just a few taps on the screen or in the TBB Connection APP, you can easily customize battery behavior, charging preferences, display settings, and quick-access controls to suit your unique needs.

One Screen vs. Multiple Devices

You're parked at a remote campsite. The sun is setting and suddenly your old system throws alarms from different modules — battery low here, inverter overload there. You waste precious minutes checking each screen and app while your family waits to cook dinner.

With separate devices, alarms get missed, you constantly switch between tiny displays, and adding a new battery means reconfiguring everything.

LIBER43 ends that hassle for good.

1. One clear screen + your phone — instant alerts, complete visibility
2. Physical POWER knob — turn the entire system on/off in one second, even at night or with gloves
3. Automatic module detection — expand your setup effortlessly

One glance. Full control. Real peace of mind — whether you're at a crowded campsite, driving mountain roads, or living full-time off-grid.
