For anyone interested, I did get through to Bill Todd at Apollo in regards to the MPPT state flashing on the display.of the T80 controller. Turns out whenever MPPT is displayed, it will be flashing. Not clear on the reason for the choice to make it flash, but it doesn't mean anything except that it is putting out optimal power.

---------- Forwarded message ---------- From: Howie Michaelson <ho...@suncatchervt.com> Date: Mon, Nov 30, 2015 at 10:55 AM Subject: Apollo Charge Controller To: RE-wrenches <re-wrenches@lists.re-wrenches.org> Wrenches, Does anyone know whether a flashing state of "Bulk MPPT" on an Apollo T80 Charge controller means something other than the first stage of the absorb cycle? This is on a DC coupled Net Metered system installed by another company which is long since out of business. I've looked all through the manual and cannot find any reference to the State in flashing mode. In fact, it does not even list any State value having "MPPT" in the value...
