the cargo compartment under the truck cab sleeper compartment. It draws
fuel from the truck's diesel fuel tank and electric power from the TriPac
Envidia batteries.

Control Circuits
The primary control circuits operate on 12 Vdc supplied by the system
batteries. The compressor control circuits operate on 230 Vac supplied by
the Compressor Drive Module.
Power Sources
All of the onboard batteries of a truck with the TriPac Envidia system can be
thought of as a reservoir of electrical power. When the truck is parked, the
TriPac Envidia system, and any other electrical devices in use, will consume
the power in this reservoir. The faster the power is consumed the sooner the
reservoir will be empty.
