HowieI here in Hawaii, we are slow to approve new inverters and it takes a very
long time to get through permits so l can't say much about the SMA -40
Inverter. Regarding wifi vs hard line, maybe for one unit it would be easy but
we just installed 27 of the SMA 24K -22 at one location and hard wire is the
only solution with all the updates and programming we need to do. I do feel a
display would be a help as " in front of the inverter trouble shooting" is
better, there is talk about phone apps but just more crap to have to look at in
the bright light when a built in basic display would be a better solution.On
the topic of hard to read display lenses, use headlight lense cleaner, makes a
big difference.Jerry

In the Caribbean, the SMA displays all turn yellow and become opaque. I use the
bluetooth feature for programming them.I won't miss the useless displays.

Howie: I have not tried the Wi-Fi capabilities, so I cannot comment on that
aspect. What is relevant, however, is the news I received from a reliable
source that the 40 series inverter will be the last residential inverter
manufactured by SMA that will have an on-board display. As evidence of this,
look in the manual for a 40 series or even a 22 series inverter- there is no
description at all of the display functions. Odd and disappointing. SMA
should have a representative on this list. It may still be Steve Jefferson,
who is a stand-up guy. SMA, what say you about these communications and display
questions? Wrenches, if you think having an on-board display is important,
voice your opinion. If the Wi-Fi is problematic, this is not a good direction.
A lot of my clients are elderly and they are not as adept at computer or
device based operations. A display is essential in my opinion. SMA, please
don’t kill the display. William Miller

Subject: [RE-wrenches] SB -40 Wifi I am looking for comments on the viability
of the Wi-Fi option of the new SB -40 inverters. I noticed some concern here
about the poor performance of this option and am trying to decide whether to
use it in the case of a long distance between the inverters and the router.I
can place a repeater between the inverters and as well as purchase the external
antenna option from SMA for the inverters, but would like to have an idea ahead
of buying and installing the 2 antennas if this is likely to work. I do have
the option of running an Ethernet cable, but it is a long (500' +) and
difficult pull. Any comments or suggestions would be appreciated.Thanks,Howie
