Friends!
We have been installing  the SMA-40 inverters lately. We like the physical
layout of the inverters.  They have built in wifi capabilities. On paper
this sounds good.  In practice this part of the inverters have been working
like crap.  We have multiple sites that are experiencing on going
connectivity issues even with excellent wifi signals.
We have upgraded to the latest firmware 3 times in the last 3 weeks for
inverters manufactured in late October.  Clearly they see they have issues,
due to the frequency of firmware updates.  Even the latest firmware is
proving useless.  Anyone else having trouble with these inverters?  We feel
like we are their experimentation lab and doing their R&D on our dime.
Their tech support is minimum an hour wait on hold.  We have spent more
time trying to resolve the communications issues than the actual
installation of the whole solar system took, not just the inverters.  In
fact I am typing this email as I am on hold.
Any one else having issues with this part of the inverters?  Advice on how
to deal with SMA or resolve the issues with out resorting to their useless
tech support?
Thanks!
