this question is part 2 about the
customer with the used astropower 75 watt modules - he has a grundfos 11sqf-2 already set by the well driller. the input specifications for the cu200 pump & controller are 30 to 300 vdc, 1400 watts, 8 amps. this will initially be running array direct and i am trying to figure out the wire loss from the modules to the cu200 controller. to do that i need voltage and current numbers. im assuming the higher the voltage the lower the running current? from the specs above: 1400 watts divided by 8 amps = 175 volts... so if i feed this with closer to 300 volts would that mean the running current would drop to around 4.6 amps? thanks for the help, todd |
