SP is a solar charge controller with built in Maximum Power Point Tracking (MPPT) technology, which enables them to increase the output from a solar photovoltaic (PV) array by as much as 30% compared with non-MPPT designs. SP can optimize the PV’s output and eliminate the fluctuation due to shading or temperatures variables. It is a multi-voltage MPPT with built in sophisticated battery charging algorithm, of which could support a wide variety of system designs. Meantime, the data management with 120days of history record can tell user actual performance of thy system. Nominal battery voltage PV open circuit voltage (Voc) Thanks to its self cooling design, it is suitable for most rugged environment with dust or bugs. All SP range products can operate at their full rating in ambient temperatures as high as 45 . Recommended PV For off-grid photovoltaic system up to max 5kW Peak efficiency 98% Excellent performance at sunrise and low solar insulation levels Low self consumption Continuous operation at full power up to 45C without de-rating Self cooling design for high reliability Built in TBB premium II battery charging algorithm for lead acid battery Built in auxiliary contact Data logging Extensive networking and communication capabilities - Auxiliary contact - RS485 : communication among TBB products or with others - CAN: Controller Area Network Maximum output current (45 ) Max efficiency (full load) Standby power consumption Charging algorithum Temperature compensation Equalization charging Communication port Dry contact Data logging Operating temperature Dimension (LxWxH) - mm Weight (kgs) Max wire sizes Protection 1 programmable 120days of history record - AH, WH, time in float, peak watts, Amps, Solar Array voltage, Max battery voltage, Min Battery voltage and Absorb for eady day along with total accumulated Amp Hours and kW hours of production -40 Cooling Standard
