1. Tibet naqu 22KW solar pumping system
Project name : 22KW solar power system
Execution time : September , 2012
Installation location : Tibet
●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 .
