Now add the two pairs in parallel. Remember in
parallel, voltage remains the same and amperage
adds. Each pair produces 140V, so total voltage =
140V. Each pair produces 1.43A, so total amperage
is 1.43 + 1.43 = 2.86A. Watts always add, so
100W x 4 = 400W.
Cable sizing chart
Since the SQFlex motor operates at peak efficiency
with 120V or greater applied, we strongly recommend
configuring panels to achieve 120V or greater.
Lower voltages result in greater losses in the drop
cable, and it is important to the customer to make
efficient use of every watt generated. Additionally,
significant savings in drop cable costs can be realized
by configuring for higher voltages.
Notes:
Max. cable length in ft; uses a max. 3 % voltage drop.
Based on the Grundfos GF100 panel.
Max. cable length between CU200 and SQFlex = 650 ft (198 m).
