[RE-wrenches] Morningstar new battery backup , more comments and opinions

[Steve Bell]

Hello William,

I had not seen the video prior to your posting. I totally agree that a one
day install of a complete battery back-up retro-fit is completely
unrealistic. Perhaps 4 to 7 days, depending on the complexity and size of
the retro-fit. Yes, one day might suffice to install and wire just the
TS-MPPT-600-TR, but creating a sub-panel, installing and wiring the
battery-based inverter and the battery bank will require significantly more
time.

I have spoken with our marketing department, and they will be addressing
this misrepresentation.

I believe all our printed literature for the TS-MPPT-600 is accurate and
does not contain any misrepresentations.

I am sorry for the unrealistic expectation that the video currently
creates. Unrealistic expectations are never good for the industry.

Respectfully,

Steve Bell
