Date:2013-4-7 Views:1537

  Project name : 22KW solar power system

  Execution time : September , 2012

  Installation location : Tibet

  Projectdesign :

  ●Solar panel array 22.5KW

  ●MPPT solar pumping inverter 22KW 1set

  ●Solar lighting protection combiner box 2sets

  ●Three-phase asynchronous motor pump 1set

  ●Water well and water tower sensor  

Project introduction :  solar panels adopt connection in series first , then in parallel as strings , then all the strings connect to lighting protection combiner box , finally connect to MPPT solar pumping inverter ,  via MPPT algorithm of inverter to track the maximum power point, adjust output automatically , with high efficiency and low cost .

Water well sensor and water tower sensor to test low and high water level . When the tested water level of water well is lower than low water level , the pump will stop work . It will restart once the water level recover to the point between low and high water level . When the tested water level of water tower is higher than high water level , the pump will stop work , only will restart the work once the water level recovers to the point between the low and high water level .
