Solar Boost 2000E MPPT Charge Controller. 25 Amp, 12 Volt

Patented Maximum Power Point Tracking (MPPT) technology allows Solar Boost 2000E to increase charge current up to 30% more compared to conventional charge controllers (average yearly gain will be around 10-15%). ** Note: Max input voltage (Voc) on this controller is 30 volts DC, so it cannot be used with the higher voltage solar panels, such as the Kyocera KD210. For those panels we suggest using one of the Morningstar MPPT charge controllers.

The Solar Boost 2000E provides a TWO stage Pulse Width Modulation (PWM) 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. A built in LCD digital display monitors solar charge performance.

*** Note for AGM's (Concorde PVX or LifeLine), or gelled batteries.

The float voltage will have to be readjusted down to around 13.43 volts using the internal pot inside the controller. Instructions for adjusting it are in the owners manual. ***

The display shows battery voltage, solar panel current and output charge current. You can actually see current boost working by noting 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.
