Hi all,
Yes the history of SMA
missing the boat with supporting off-grid in the U.S. goes way back to
the John B. and Sam V. days - they really tried going way back to the
90s. Germany would just not prioritize it.
I was one of the
early beta testers of the SI - it's by far the best system out there -
if only they would offer a split-phase.
Now the game is to see
who gets to really supporting high-voltage Li WITH off-grid support of
generators as well as grid-tie sell-back. Outback and Pika - game on!
I
sure wish SMA were in the running! - we'll see with the SBS but
probably no generator support right Mike?
What can we do to get
the message through Mike? Okay I'm probably dreaming.
For what
it's worth,
Jeff

That being said, SMA is loosing a lot of sales by not having a split
phase Sunny Island on the market. It would be my unit of choice for many
application that I have gone with other brands. The price of a pair of
SIs is often just not competitive.

Tump - You are right about the large number of times that has been
asked,
and I wish I had a happy answer.
However, with all the work on Sunny Boy Storage and Sunny Central
Storage
(and even a Tripower storage), resources to develop and test a split
phase Sunny Island are not available. There is active work on
updating the communications to support SMA’s Ethernet based
communications. Still, this may be months out.
With the Smartformer being discontinued, the MidNite MNX-240 is the
recommended part to create 240 split phase from one Sunny Island.

Mike

Once those units have all required listings/certifications and are
available in US, they should be ready to use with SBS. The CANBUS
comms to the BMS has already been vetted, and they are on the SMA
Approved battery list already. But I will get confirmation on the
immediate usability.

- Marco and all – yes that is the correct spec ssheet for the BYD
batteries that will work with Sunny Boy Storage.
-
- SMA strongly would recommend the Sunny Island for off-grid in
general
and certainly whole home backup. See the attached from Home Power
April/May 2011; quad stack of SIs acting as UPS for the home – just
charging batteries when grid is prresent, powering home with
batteries/PV
when grid is gone. A dual split phase cluster is almost 24,000 W
continuous (!) capability and can handle crazy power factor loads with
no
issues. Built in generator functions and two relay positions per
Sunny Island allow for lots of redundancy and fail-safe load shedding to
be built in.
-
- The Sunny Boy Storage (SBS) is designed to be a grid-tied
inverter to
allow higher self consumption of local PV power. Even with the ABU
to allow off grid operation (grid forming on its AC outputs rather than
just on the dedicated 120VAC Secure Power Supply outlet), there can be a
several second delay in the switch from grid power to microgrid as the
ABU must signal the Sunny Boy Storage that it has disconnected from the
grid and that it is safe for the SBS to form a grid on its output
terminals. Also be aware that there is no master-slave
configuration ability with the SBS – they will always assume they are
acting independently on their energy meter input information.

- Attached is the spec sheet on the BYD battery in question.
-
- I’ve confirmed with SMA directly that there’s no capability
for
the Sunny Storage design (S.S., ABU and battery) to use a generator
input. My apologies for mis-stating earlier that it could
accommodate a generator.
-
- As far as grid-tie with batteries, the Holy Grail as far as
I’m
concerned is being able to provide whole house back-up and not have to
do
the old fashioned and pain in the arse critical load sub-panel. The
more choices that we’re provided, the more better. So I’m
pleased that companies like SMA, Ensync, SolarEdge and others are
bringing new equipment and designs to market to allow for whole house
back-up.

- HI Harry,

- The battery is charged from the AC side correct?
- And is the charging algorithm inside the ABU.

The SMA Sunny Storage looks
promising.
It will be able to work with the LGC RESU10 HV battery and,
sooner rather
than later I hope, BYD package as
well.
And it will allow for a backup generator tie
in.
Ta-dah!
