Hi Wrenches, Has anyone put to use the solar drives such as the ABB solar pump drive for other motor applications? I'd like to power a 2HP regenerative blower on solar direct if possible. I don't know why it wouldn't work but they are pretty specific when talking about pumps. Thanks! --

Howie, As far as I know, and I have not researched this, The El Sid drivers mate to the pump bodies used with March 809BR and 809BR-HS hydronic pumps. The March pumps use brush-type conventional 12 and 24V DC motors. I have heard, but can't confirm, that Dan Fieldman developed the El Sid (Sta
