Subject: Re: [RE-wrenches] Blue Ion BMU issue request

Good Morning, Allan,

I'll share my limited insight in hopes it proves valuable to you.

Have you had any Blue Ion battery or BMU failures?  If so, how many systems 
have you installed, and how many failures have you had? What failed, and what 
did you do to resolve the issue? If you replaced a BMU, was the process 
straightforward, and were you given a complete set of documentation with the 
unit? Was the factory warranty process honored?

We have nine sites with Blue Ion installed.  These range in size from a single 
battery module up to 48 modules.  They are mated to a range of chargers and 
inverters from Outback, Magnum, Midnite, Schneider, and Sol-Ark.  We have only 
experienced an issue at a single site and that was a battery module.  Blue Ion 
was extremely attentive from a customer service perspective.  They mailed 
problem-specific testing equipment along with the RMA'ed parts, provided live 
customer-support during the testing, and provided return shipping.  All was 
covered by warranty (I do not know if there was a labor reimbursement).

On a related track, how have you responded to Blue Planet's offer? Does it come 
across as a valid solution? Have you bought one or more spare BMUs? How are you 
supporting your Blue Ion customers going forward? Have you received support of 
any kind from Blue Planet?

Our company took the same approach you did, sending an email to our customer 
base informing them to consider purchasing a back up BMU.  To the best of my 
knowledge only one of our customers has opted to purchase a back-up and they 
are an energy utility with two large, high-consequence systems that easily 
warrants the ROI.  We as a company are leaning toward not purchasing one to 
"have in stock".

Sincerely,
Sam
