Hi All,
I'm trying to verify what my outsourced system designer has sent for us to submit.
Project characteristics:
58.5Kw - (180) Hyundai 325W ground mounted
4 inverters - (3) 12.5kWW Fronius Primo 240V single phase and (1) 15.0Kw
12.5kW - (4) Strings of 11 Paralleled to 1 output for reduced wiring - These paralleled circuits (3) will travel in 300 ft of PVC, what size conductor?
15.0Kw - (4) Strings of 12 Paralleled to 1 output for reduced wiring - This paralleled circuit (1) will travel in 300 ft of PVC, what size conductor?
Inverters are 300 ft away from the Array and DC combiner. Combiner Rack Output = (4pos) + (4neg) + Ground. Same Conduit for DC PV to Inverter Run (300ft.)
How to calculate and verify?
Here's what my designer has so far:
Can you find any discrepancies? Any help/advice is humbly welcomed!
