I know that using a combined solar array to power 2x MPPT drives is not recommended because the MPPT algorithms will not work at its peak efficiency.... But...
I want to test run a DC Solar bus installation (about 5kWp) to drive a MPPT Charge controller and a Solar Pump VSD. The advantage this is that:
a) I do not run the pump every day and then I can use that solar power from the array to charge my batteries or run other loads.
b) If the sun is not shining I don't have to worry that the pump may drain the batteries, which would have been the case if the pump was powered by the inverter.
c) I can get away with a smaller inverter since the pump is powered from the solar VSD only
d) I can power the solar VSD from the inverter if I need to, e.g. at night time.
Any comments?
