Thanks for all the input. These batteries do look impressive, and the project is somewhat absurd... Like I said, not my idea I just have to make it work.the utility and the authorities are cracking down out here. My company is looking for solutions... I get to be the one to make it happen, or well, take the blame I reckon.

Like most Americans my German is horrible, but I will look into the settings, I hope I can get some good info. Thanks guys! I'll keep you posted win or lose.

Hi again

You should  first of all read the Post  in this thread from Rogeriko and Knighty  here  
And supply more Info about house consumption PV orientation , PV gain  per day / month year (is it about 1400 kWh/KW PV ? per year)

Those batteries are intended to be cycled down to close to nil
Charging through the Grid during the day  while PV is charging with the Sunny boy , could be a  mismatching configuration  and somehow stupid  ,
or do you disallow the SI to charge during the day , while sun is out and noone at home .

A more efficient MPPT chargecontroller would have been the better match here and far more efficient  and cheaper ! Instead of the Sunny Boy 

Quote
The customers come home around 4:30 p.m. and turn on the air-conditioning and start the laundry, I set the The Sunny island to allow grid power to answer the load demand at about 7 Kw. I also set the grid charge start to charge the batteries when the Soh drops to 75% and stop at 90%

I read the German Thread  , but  i guess Paul was more  or less kidding , or ??

Not sure , if the Nissan leaf Lixxx battery  thread  with Sunny Island  and Sunny boys   on that German  PV forum (in english)  would be more interesting..... whistlie  to read more native Germans like me , speaking English  whistlie

It seems a really interesting forum Billi, wish I had a grasp of German, the 'Google translate' kinda works until it gets technical. Wish my 'Island was Sunny' right now, I'll get precious little sun on my panels until next year  Cry
