Does anyone have any manufacturers they’d recommend for a rooftop NEMA4 AC combiner panel? I have four 30A 480v branch circuits coming from Yotta DPI-480 micro inverters. I’d rather combine up on the roof than bring each circuit into the panel board at the meter.
I’ve used TerraSmart (Solar BOS) AC combiners before (https://www.terrasmart.com/wp-content/uploads/2021/10/SS08-SolarBOS-AC-Combiners.pdf).
Was wondering if anyone else had a better solution? This is relatively small at 100a of calc’d load.
A QO panel board with the smallest frame calc’d out at $10k with a 100a main breaker. I’m pretty confident we can do better.
