Manufacturer's Description

Patented Maximum Power Point Tracking (MPPT) technology allows Solar Boost 2000E to increase charge current up to 30% or more compared to conventional charge controllers. Don't waste money by throwing PV power away! Get the power you paid for with a Solar Boost charge controller.

A built in LCD digital display monitors solar charge performance.The display shows battery voltage, solar panel current and output charge current. You can actually see current boost working by knowing the difference between solar panel current and output charge current. A charge status LED indicates the present charge mode, and shows when the battery has become fully charged.

  • Patented MPPT technology increases charge current up to 30% or more!
  • 12 Volt / 25 Amp rating supports wide range of applications
  • Electronic current limit prevents overload or nuisance fuse blow
  • LCD digital display monitors PV charge performance
  • Durable powder coat finish & conformal coated electronics resist corrosion
  • Available temperature compensation further improves battery performance and life
  • Fully protected against excess current, temperature, transient voltage and polarity
  • Full 5 Year Limited Warranty

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 2000E is a 25 amp 12 volt Maximum Power Point Tracking (MPPT) photovoltaic (PV) battery charge controller with built in digital display. Through the use of patented MPPT technology the 2000E can increase charge current up to 30% or more compared to conventional controllers. The 2000E's sophisticated charge control system improves battery performance and life while minimizing battery maintenance. The unit is fully protected against voltage transients, over temperature, over current, reverse battery and reverse PV connections. An automatic current limit feature allows use of the full 25 amp capability without worrying about overload or nuisance fuse blow from excessive current. An environmentally sealed high current high reliability relay is used to disconnect the PV array at night to prevent unwanted current drain.
