Heinrich Eurich reports on his initial experiences with his PV storage system comprising the Sunny Boy Storage and Tesla Powerwall. As part of the field test for the Sunny Boy Storage, the SMA employee was one of the first to have the new storage system installed. <\/em><\/strong><\/p>\n

\u201cDarn it, back payments again!\u201d That\u2019s how I always reacted when the annual electricity bill from the public utility company dropped into the mailbox.\u00a0\u201cDad, we have enough power from the roof, why do we need to pay for more every year?\u201d asked my son.\u00a0\u201cBecause the sun doesn\u2019t shine at night, it\u2019s that simple,\u201d I explained.<\/p>\n

And somehow this very fact had always bugged me. Because my PV system actually generates too much electricity at 15.6 kW peak\u2014just not always at the right time, unfortunately.<\/p>\n

We need a lot of power in the evening especially, when our family of four comes back together after a working day: The TV, electric stove, electric kettle, computer, hot water heater and heating are our typical loads in the evening hours. Hot water? Heating? You got it. We don\u2019t need gas or oil, we generate our energy carrier ourselves and \u201cburn\u201d it with an air-to-water heat pump.<\/p>\n

So I was confronted with the issue of a \u201csuitable storage system\u201d since building our new home in 2011. Unfortunately, the implementation always fell at the hurdles of efficiency and space\u2014we did not build a basement.<\/p>\n

 <\/p>\n

Next electricity bill eagerly awaited<\/h5>\n

And then the little, white Sunny Boy Storage and the slim, pretty battery arrived together.<\/p>\n

The Tesla Powerwall was mounted flat on the wall, next to the little Sunny Boy Storage, with just a cable channel with the appropriate cables between, and the system was ready. A work of art for the garage. We have lost practically zero storage space in the garage, just as I always imagined it.<\/p>\n

 <\/p>\n

Conclusion after 40 days of operation from April to May:<\/h5>\n

Power purchased from the grid for about \u20ac 5\/month; we can surely improve here. However, when compared with before, \u20ac100\/month over the year, this is a great success.<\/p>\n

Of course, the result will get worse in fall and winter, but when you think that we will achieve good average yields from early March to the end of September, there is a good chance that our electricity costs will fall by at least half. We are already looking forward to the next electricity bill.<\/p>\n

\u201cNow we must be able to afford a PlayStation,\u201d said my boys. They\u2019re always quick when it comes to such \u201cinitiatives.\u201d I am more for a little family vacation, let\u2019s see who wins.<\/p>\n
