PRODUCT DESCRIPTION
Solar Boost™ 3048 is a 30 amp 24/48 volt Maximum Power Point Tracking (MPPT) photovoltaic (PV) battery charge controller.
Through the use of patented MPPT technology, Solar Boost 3048 can increase charge current up to 30% or more compared to
conventional controllers. Solar Boost 3048’s sophisticated three stage charge control system can be configured to optimize charge
parameters to precise battery requirements based on battery electrolyte type, battery size in amp-hours, and battery temperature.
The unit is fully protected against voltage transients, over temperature, over current, and reverse battery and reverse PV
connections. A manual equalize function is provided to periodically condition flooded lead-acid batteries. Solar Boost 3048 also
includes an automatic current limit feature which allows use of the full 30 amp capability without worrying about overload or nuisance
fuse blow from excessive current.
Solar Boost 3048 employs series pass Pulse Width Modulation (PWM) charge voltage control. The multistage charge control
system combined with precise PWM voltage control leads to superior charging and enhanced battery performance. To provide
optimum charge control on installations where battery load varies widely during charge, Solar Boost 3048 can interface to an
external current shunt to provide optimal charge control. The PWM control system uses highly efficient and reliable power MOSFET
transistors. The MOSFET’s are turned on and off at high frequency to precisely control charge voltage and MPPT. Environmentally
sealed high current high reliability relays are used to disconnect the PV array at night to prevent unwanted current drain. Relays are
used rather than blocking diodes for improved power conversion efficiency, current boost performance, and true reverse battery
polarity protection in an MPPT controller. The relays are not stressed by functioning as part of the voltage control system and
continually turning on and off as with other PV controllers. They simply turn on in the morning and off in the evening, and in this
application have a life expectancy in excess of 10
5
operations.
Fully automatic temperature compensation of charge voltage is available as an option to further improve charge control and
battery performance. The available SensorLug™ battery temperature sensor is built for long term reliability. The sensor element is
environmentally sealed and encapsulated into a copper lug which mounts directly to the battery terminal. A user friendly digital
display is also available to monitor PV charge performance. The display may be provided in the Solar Boost 3048 controller, as a
remote panel, or both. The remote panel cable may be up to 300ft/91.4m in length.

OPERATION
¾ Once installed and configured, charge control and MPPT operations are fully automatic. Charge turns on
whenever the PV array is capable of producing
≈0.2 amps at ≈2.5V greater than battery voltage. When PV
charge is on the Charge Status LED will indicate the present charge mode, and when PV power production
is relatively high, it will show approximate battery state of charge. At night when PV power production stops,
the PV array is disconnected from the battery to prevent unwanted current drain.
¾ Après l’installation et la configuration, les opérations de contrôle et les opérations CONVERSION
OPTIMALE D’ÉNERGIE sont automatiques. Le chargement démarre lorsque l’intervalle PV peut produire
de
≈0.2 amps à ≈2.5V plus que le voltage de la batterie. Lorsque le chargement du PV est en cours,
l’indicateur (LED) d’état de charge montre le mode de chargement actuel, et lorsque la production de
puissance photovoltaïque est relativement élevée, l’indicateur montre l’état approximatif de charge de la
batterie. Pendant la nuit, lorsque la production de puissance photovoltaïque s’arrête, le réseau
photovoltaïque doit être débranché de la batterie pour prevenir les fuites de courant.
¾ Nach der Installation und Konfiguration, sind die Beladungskontroll- und MPPT Operationen vollständig
automatisch. Die Beladung schaltet ein jedesmal das PV System ist fähig, mehr als
≈0.2 Amps bei ≈2.5V
höher als die Batteriestromspannung. Wenn die PV Beladung eingeschaltet ist, wird das Beladungsstatus
LED den aktiven Beladungsvorgang andeuten, und wenn die PV Stromerzeugung relativ hoch ist, wird es
einen approximativen Batteriebeladungsvorgang anzeigen. Während der Nacht wenn die PV Erzeugung
aufhörtm wird das PV System von der Batterie ausgeschaltet um eine ungewünschte Stromausladung zu
vermeiden.
