[RE-wrenches] Enphase performance

[Randy]

Hi Marco,

We definitely experienced an overstatment. 

 

We have a client who installed 5kW on a string inverter and 5kW on enphase
and it is that side-by-side comparison that enabled us to positively
identify a problem. There was a significant overstatement of output. We
finally got a Enphase person who told us it was a software glitch. The
problem appears to be fixed.  They explained to us that our problem was
isolated without giving us a detailed explanation of what happened.  Since
that problem was fixed, we have seen no difference in output between a
string inverter and enphase.

My biz partner has an Enphase system with BP Solar mods.

 

He believes that the web-based monitoring system may be reporting on the
high side as far as kWH performance over time.

 

That is, he suspects that what he's seeing may not be accurate.

 

Anyone out there have a similar experience?

 

Thanks,

marco
