1. SP200 PV Pump Controller continuously monitors the performance of the system and can detect a variety 
   of anomalies.

2. SP200 PV Pump Controller automatically detects the ambient temperature. When the temperature is too high, 
    the controller will reduce the output power to maintain running as far as possible; When the controller temperature
    is cooled to a safe level, return to full power output.

3. SP200 PV Pump Controller integration improved MPPT algorithm, variable step size in real time tracking the MPP. 
   Compared to a conventional constant-voltage control (CVT) method more precise tracking, faster response speed,
   and overcomes the shortage of conventional disturbances tracking method near the MPP wide fluctuated running.

4.When SP200 PV Pump Controller fails, the panel LEC will display fault types, automatic reset common-cause 
   failure, and according to the degree of light sleep and awake to ensure the controller runs automatically the whole
  day .
