Jupiter Manual

Comprehensive electronic protection The charger is protected against overtemperature (bottom plate >90 °C) by reducing the output power when the maximum product temperature is reached.

• Protected against overload • Protected against short circuit • Protected against excessive temperatures

Adaptive charging in four stages The Jupiter is configured by default for a four-stage charging process. • Bulk — Absorption — Float — Storage • Bulk During this phase, the Jupiter supplies as much charging current as possible to quickly charge the batteries. • Absorption When the battery voltage reaches the absorption voltage setting, the charger switches to constant voltage aka absorption mode. For lead-acid batteries, it is important that the absorption time is kept short during superficial discharges to avoid overcharging the battery. After a deep discharge, the absorption time is automatically increased to ensure that the battery is fully charged again. For lithium batteries, the absorption time is fixed, 2 hours by default. Fixed or adjustable modes can be selected via the battery settings. • Float During this phase, the battery is charged with a trickle charge voltage to keep it in a fully charged state. When the battery voltage drops far below this level, for example, due to a high load for at least 1 minute, a new charge cycle is activated. • Storage The battery voltage is maintained at the configured storage voltage, which is slightly reduced compared to the float voltage to minimise gassing and extend battery life whilst the battery is unused and on continuous charge. Flexible charge algorithm The Jupiter has fully programmable charge algorithms and eight pre-programmed battery settings. Configurable with VictronConnect. Adaptive Absorption Time In adaptive absorption time mode, the correct absorption time is calculated automatically. Configurable with VictronConnect.
