Drake Let me explain, I have worked with the large inverter 4kW and Magnum 4024 AE extensivly, trying to get it right. The Magnum was starting a large motor reliably (in fact it never missed), but the Outback did not start the motor at all well. So I settled on the Magnum, and did little work on this install with the Outback.
Yes the Outback and the Magnum caused the DGI inverter to drop out, but I was not understanding what was happening, and I am not sure I got it correct. But with the magnum I was trying to make it work with a 4 kW DGI inverter and it would work fine as long as the solar was not to bright or all the panels were hooked up. I went through several tests with the Magnum (days)and every time it got over 50% the posibility of shutdown. I tried over and over again. I did not do this with the Outback as it turned out, but I have had unexplained bright sun cold modules when near 50% load DGI kickout, with the Outback. I would like to know if the Magnum 4024 PAE would be the same and if two magnums would handle the load, but we are all limited finacially. --- On Mon, 12/27/10, Drake <[email protected]> wrote: > From: Drake <[email protected]> > Subject: Re: [RE-wrenches] Component Choices for MY RV - Apollo Solar? > To: "RE-wrenches" <[email protected]> > Date: Monday, December 27, 2010, 9:10 AM > Have you found the 50% capacity true > for Outbacks?
