one of the jobs I been talking about customer asked about control and the unit is a Westinghouse, I dont have the model but I can ask for tomorrow. As far as i know they asked someone at reps that there no way and dont want to have 3rd party controllers. But I saw a link that theres this Interface that can integrate those units, I dont have the info with me is in my desk. Anyway anyone controlling Inverters? or any particular brand?
