Pond Boss Forums AERATION Systems questions 8 acre pond at 10,000' - lots of aeration ?s

ABB Solar Drive (ACS355 Machinery Drive with the MPPT Solar Algorithm), for a 1HP drive is $342.30. It will work at 10,000 ft without a huge derate. When you get that high, the limitation is the dielectric insulation properties of the thin air on the I/O board, but I rarely use them, and would not in this app.

The PF525 drives I have will go to 20,000 ft.

I'm going to order the 1HP ABB drive because I need another one, and this will also run from 240VAC single phase.

Still searching for decent panels.
