If the system has turned off for low power reserve, it may be turned on by
pressing the On/Off button on the HMI for at least one second. The system
batteries should have been fully charged by running the truck before turning
the system on again. If the batteries are not charged, the system may
immediately turn off for low power reserve or have very short run time.

Battery Charging
Truck Running
Charging amperage is provided by the truck alternator. A 270 amp alternator
is the minimum required to support the TriPac Envidia system. For many
applications or truck operation profiles, such as high tractor duty load, high
driver “Hotel Load”, extended layover duration, high ambient temperature
or short drive times between layovers, increased battery charging capacity
may be required. Undersized alternators will increase TriPac Envidia charge
time. The truck alternator will spend a higher percentage of operating time at
maximum output. This may shorten the life of the truck alternator. To
provide the additional charging capacity, the alternator and charging cables
