<div dir="ltr">Friends!
<div>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.
<div>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.
</div>
<div>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?</div>
<div>Thanks!</div>
