ENERGY FLOW

How power moves through the system.

While the truck runs, the alternator charges the lithium bank through a controlled DC-to-DC charger. Parked, that stored energy runs the compressor, fans and cabin power — no main engine required.

Alternator — generates power while the truck is driven.

Controlled DC-to-DC charger — regulates current into the battery bank.

Lithium battery bank — stores energy for overnight use.

Electric APU compressor — cools the sleeper using stored battery power.

110V inverter — powers cabin devices without the main engine running.

PROTECT THE TRUCKunverified

Fewer idle hours. Less wear on the systems that keep you compliant.

Reducing unnecessary idle time may reduce exposure on NOx sensors, DPF pressure and temperature sensors, exhaust temperature sensors, SCR, DEF dosing, and EGR components.

QUIET COMFORT

Sleep without the engine running underneath you.
