The TRACER 1210A is a charge controller with MPPT technology (Maximum Power Point Tracking), for use in photovoltaic systems. Through the use of MPPT technology, Tracer can increase charge current up to 30% or more compared to conventional controllers. The sophisticated charging three-phase system can be configured to optimize the charging parameters in accordance with the technical specifications of the battery. The controller is protected against voltage spikes, over temperature, over current, reverse polarity.
The charging voltage control takes place in MPPT, combined with a multi-phase control system. This ensures greater efficiency and battery life. The MPPT control is implemented thanks to the MOSFET power transistors, which are turned on and off in high frequency PWM to control the charging voltage in a precise manner.
This type of charge controller is equipped with display which has the purpose to show the status of the controller work and of the accessories connected to it (panels and accumulators). In addition to this function also it carries out maintenance of the battery is avoiding the overhead that underdischarging. These functions are automatically performed by the charge controller on the basis of the threshold voltages which are respectively HVD (maximum disconnect voltage) and LVD (minimum voltage of disconnection). In this way it gives the opportunity to accumulators to remain more efficient and longer in time.
These disconnection processes, automatically performed by the charge controller, are based on an automatically calculated parameter and maintained by the same regulator, ie the SOC, ie the state of battery charge.
This charge controller, for the calculation of the SOC, uses an integrated circuit capable of cutting edge calculate with great precision. The SOC is a very important parameter on which they are based protections for overload and undershooting. An additional parameter based on the SOC is the LVR (reconnection of load voltage). Leveraging this parameter, the controller can understand when accumulators are quite loads can be reconnected to the load (as with LVD protection accumulators may be disconnected from the load).
