Model 12 Volt 25 Amp - SB2000E MPPT Solar Controller
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 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.
