I will not engage any further in this banter. we paid for a working system , that never worked. your liability
extends further than storage as you are well aware. . so I suggest you proposal gives us what we paid for. or
we will need to pursue options that will undoubtedly result in significant dollars damages to you . we would
hope to avoid this . Your liability is clear. Sending me the cost of a new turnkey system is bad faith.

It's been stated repeatedly that the storage portion is the issue and all other components are performing as
designed and intended.
My conversation with Mr. Epstein indicated as such and our continued efforts have shown this to be the case.
In fact, the recent exchanges are principally driven by the report in which we've found 30% of the Aquion
battery stacks have failed.
Our conversation the day before yesterday was also centered around storage composition.
Additionally the warranty you refer to is specific to the Aquion batteries, if we are using the final invoice as
the contract.

its very simple brian. we paid you for a working system. you have the obligation to replace fully at your
cost as it never worked properly from day one. the addtional money we paid for your attempts to fix will
be added to any litigation claims plus damages of course. So as to be crystal clear again: The total
expense to replace the system is yours and yours alone. If you want to send us a check for all money paid
to you to date including purchase and maintenance that could be an alternative.

Good Morning Richard,
Last night I received another response, this time using a Lithium Ion battery.
We are currently revising our contract and estimate template so please consider this a "turn key" quote for
the storage component of the generation and primary distribution system. If you decide that this is the
configuration you wish to move towards, a formal quote and contract will be finalized.
The lump sum cost to replace the Aquion salt water batteries with a 300+kwh Lithium Ion composition
storage system is $410,205.28. This includes all integration and communications for a "turn key" product
with a 3-4 month lead time. The Tesla PowerPack is an option that is considerably less per Kwh but the
lead time is unknown and has been discussed as a year or longer.
In an effort to ensure we are interpreting the warranty of the Aquion system to your satisfaction, please
share your thoughts. The invoice that was relayed used language copied from Aquion literature and states
5 years 3 years prorated. We want nothing more than to foster a good relationship and, without admission
of culpability, are attempting to stand by the manufacturers claim.

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.
