Manufacturer's Description

Patented Maximum Power Point Tracking (MPPT) technology allows Solar Boost 50 and Solar Boost 3048 to increase charge current up to 30% or more compared to conventional charge controllers. Donít waste money by throwing PV power away! Get the power you paid for with a Solar Boost charge controller.

Solar Boost controllers also provide an advanced fully automatic three stage charge control system to ensure the battery is properly and fully charged, resulting in enhanced battery performance with less battery maintenance. An equalize function is also included to periodically condition liquid electrolyte lead-acid batteries.

An optional user friendly digital display is available to monitor PV charge performance. Optional temperature compensation of charge voltage is also available to further improve charge control and battery performance.

Solar Boost controllers increase charge current by operating the PV module in a manner that allows the module to produce all the power it is capable of. A conventional charge controller simply connects the module to the battery when the battery is discharged. When the 75W module in this example is connected directly to a battery charging at 12 volts its power production is artificially limited to about 53 watts. This wastes a whopping 22 watts or nearly 30% of the available power!

Patented MPPT technology used in Solar Boost controllers operates in a very different fashion. The Solar Boost controller continually calculates the module's maximum power voltage, in this case 17 volts. It then operates the module at its maximum power voltage to extract maximum power. The higher power extracted from the module is then provided to the battery in the form of increased charge current. In conditions where extra PV power is not available, Solar Boost controllers will operate as a conventional controller with very low voltage drop.

The actual charge current increase you will see varies primarily with module temperature and battery voltage. In comfortable temperatures, current increase typically varies between 10 to 25%, with 30% or more easily achieved with a discharged battery and cooler temperatures. What you can be sure of is that Solar Boost charge controllers will deliver the highest charge current possible for a given set of operating conditions.

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 3048ís 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 multi-stage 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 MOSFETís 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 105 operations.
