Jupiter Manual

GENERAL

Introduction The Jupiter pack can be used as an integrated power conversion, battery charger, monitor, 12V power supply for off road vehicles. It is especially suitable for vehicles with smart alternators (a Euro 5 or 6 smart alternator), which often supplies charging voltage that is too low even with the engine running or in the event of a voltage drop over long cables, controlled charging is crucial. Controlled charging also protects the alternator in lithium systems from overloading, as the low impedance of lithium batteries results in a high alternator current. The Jupiter is set only to supply power when the engine is running. This is possible thanks to the integrated engine shutdown detection. This eliminates the need to adjust in-vehicle wiring or add an engine detection sensor to determine if charging can start. It also prevents the starter battery voltage from getting too low. The Jupiter is fully programmed and monitored using the VictronConnect App. This also includes remote access via VictronConnect-Remote (VC-R) when connected to a GX device (requires a GX device connection to the VRM Portal) via the integrated VE.Direct port, monitoring via the GX Remote Console or from a PC, Apple computer with macOS or Android device in conjunction with a VE.Direct to USB interface and VictronConnect. Discover all setting and monitoring options in the Setup & monitoring with VictronConnect [15] chapter and the VictronConnect manual. Silent while vehicle charging The heat is dissipated through natural convection, eliminating the need for a noisy cooling fan. Features Smart alternator compatibility It is common for vehicle manufacturers to install "smart" ECU (Engine Control Unit) controlled alternators to increase fuel efficiency and reduce emissions. Smart alternators provide variable output voltage and shut down when not needed. The Jupiter has an integrated mechanism that detects whether the engine is running (engine shutdown detection), so the charger is only activated when the alternator is supplying power. This ensures that the charger only draws power when the alternator supplies power. See the Engine shutdown detection [12] chapter for more information.

Separation of the starter battery and the service battery The Jupiter separates the starter battery from the service battery.
