TBB Power SolarMate SF100-50 solar charge controller with MPPT technology enables maximum energy tracking for solar charging. This technology allows the controller to track the maximum power point of an array quickly and accurately in any environment, obtain the maximum energy of solar panel in real time, and charge the battery at maximum current. The SF100 series controller has a built-in multi-stage battery charging algorithm, along with an MPPT algorithm that allows for wide voltage input ranges. This makes this controller suitable for charging various types of batteries, including Gel, AGM, Lithium, and traditional Lead-acid batteries. It has built in RS485 and CAN communication capabilities for system integration, as well as built in Bluetooth transmitter for monitoring and controlling from a smartphone or tablet via the Solar Mate app. The controller will also store data regarding historical events, daily power generation, monthly power generation, and total power generation. Maximum solar panel voltage: 100V Maximum solar panel power based on battery bank voltage: 800W (12V) / 1600W (24V) Battery Voltage: Fully automated operation 12V / 24V selection Communication port: RS485/RJ45 interface Grounding: negative common ground Current limiting function: 50A Self-consumption:
