[QUOTE="Bob Smith, post: 553489, member: 35176"] I know, my bio does not say yet retired and loving it :) You are right all batteries are DC and you are referring to early stage. One of the reason I did not accept batteries in 2014 and 2016 when I got my first array installed. The tech has improved a lot and if my calculations are correct. My ROI that includes the cost of the batteries will be between 7 and 10 years. To me the batteries can provide good ROI if they are sized right (ie the right ratio storage vs charge/discharge capacity and not only how much you need at night) and not only used to store excess energy but if you trade too.
