Solar Boost Solar Charge Controllers
Solar Boost Solar Charge Controllers
| 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. |  |
| Solar Boost 2000E – 12 volt / 25 amp rating. Patented MPPT technology allows Solar Boost 2000E to increases charge current up to 30% or more compared to conventional charge controllers. Solar Boost 2000E provides a precision Multi-stage PWM charge control system to ensure the battery is properly and fully charged. An equalize function is also included to periodically condition liquid electrolyte lead-acid batteries. A built in LCD front panel display monitors solar charge performance. The display shows PV module input current, output charge current, and battery voltage. |

| You can actually see current boost working by noting the difference between solar panel current and output charge current. |
