Id be amazed if you ever see an SMA fail  Im yet to even hear of it!! Yeah i figured it must be some sort of requirement, although in your case a very redundant one, i dont think ive ever seen an inverter that doesnt display total production. How close is the total reading between the inverters and the meter? |

I need to get the shade off the panels in the early morning. here is a graph of a few fellow SMA owners in NY State on Sunnyplaces.com You can see they start production much earlier than my system. I bet I can get another 3-5 kwh's a day in peak season. I am the Green curve  |

Yeah mate this is what gets mine too, both morning and afternoon. I can fix the morning issue, but not the afternoon.

Due to my near 270% arrangement mine hits full output as soon as the shade is out of the way.

2015 production. not bad , January and February sucked due to snow covered panels and an 11 degree temperature average in February.  |

You definitely do better in your winter months. I just cant get to the panels to clear the snow. But this year is much better so far. I got over 300kwh in feb compared to .077 last year Nashou |

Yeah mine holds quite evenly through the year, the biggest factor is reduced daylight hours in winter.
The 3 seperate arrays facing east, north and west give the ability to hold full output through almost the whole day regardless of the time of year.

OK solar meatheads If for only a small portion of the day, I'm looking to net 4500 watts to power a electric water heater. I have calculated the available roof space and a quick search at available panels tells me that I can gross out at over 9000 watts. Not sure how to calculate the conversion loss. I don't want hydronic solar panels because I want to collect any unused watts to charge backup batteries.
The electric water heater is not stand alone. It is currently connected as a booster tank (storage tank) off a conventional heating system and the elements are unused.
