after patiently waiting many months and having no results this email it not helpful..
we had multiple conversations this week regarding your experience with lithium after moving away from salt
water batteries yet now you are proposing nickel iron battery option..
lastly we are looking for you to make good on your warranty and are not looking for cost offsets vs a larger
number
i am embarrassed to send this email to mr epstein and advise that you send us a real proposal before this is
removed from me and turned over to our attorney...
thank you

Morning Richard,
I'm awaiting a vendor response concerning a Lithium Ion storage option but have received some preliminary
information I'd like to share.
There is a Nickel Iron battery option which has been the mainstay for the the NIssan Leaf and other electric
vehicles.
This has a 30+ year life expectancy (11,000 Cycles @ 80% depth of discharge) and is compatible with all of
the supporting infrastructure i.e. SMA inverters. chargers, etc.. Unfortunately there is a 4 month lead time for
delivery.
The initial "turn key" cost analysis for this system is $347,958.00. This is prior to any offsets.
I'll continue to pursue options but appreciate any feedback as we move forward.
