Does solar energy affect data-collection?


to-ya farm Jan 3, 2022 09:53 AM

hi ^^

my AWS structure is like below

                                                         ---(RS232)-->                                                            

  solar pannel(DC12V)-----> datalogger-----------computer(220AC) <---------swithchgear  <------public electric power
                                                 <----------------- -------(220AC for rain detector and precipitation heater)

                                                   

I want to connect solar energy(DC->220AC) to swichgear.

                                                       ---(RS232)-->                                              <--solar power(DC->AC220)    

  solar pannel(DC12V)-----> datalogger-----------computer(220AC) <---------swithchgear  <----public power
                                                 <----------------- -------(220AC for rain detector and precipitation heater)

If i did it, could it affect any trouble  for data-collection.

the reason i think so is

If a computer receives power from solar energy and power sources (from the government), is it likely to interfere with data collection? ( Because of the difference between solar power and public electric power quality

thank you.

Two things you need to consider in your wiring:

1)Proper grounding for surge protection

2)Reducing electrical noise

Follow local regulations on how to properly ground AC power. That usually involves a nearby grounding rod. The solar power system should also connect to ground. Surge protection needs a good connection to ground to operate correctly.

DC to AC converters can produce a lot of electrical noise. It is common that a cheap converter will output more noise than a more expensive model. Converters will often specify noise as "ripple". Clean power helps the datalogger make clean analog measurements. Having a battery on a power supply such as a PS150 helps filter a lot of noise.

In the analog measurements on the datalogger, be sure to use the option for 50Hz noise rejection. It will remove much of the noise from the AC power line.
