[RE-wrenches] SolarEdge 7600 and the Powerwall

[Chris Mason]

Howie,

The Sonnen Eco16 we installed is very nice equipment. I have previously
used the Radian 8048A inverter but the Sonnen adds a really nice battery
system, nice interface, and a Z-wave energy management system.
The battery system is by Sony and the stats are incredible. !0 year
warranty, 10,000 cycles, discharge to zero without damage, very good
battery management system.
The install was easy enough, connecting the mains cabling is a challenge as
there is very little room, I would definitely have a trough or some kind of
cable management device above the unit. It takes two people, one to guide
the cables into place and one to push them.
The batteries are so light it is surprising, one person can easily carry
them. This alone is enough reason to go Lithium.
I set the minimum battery reserve to 10%, this client wants to use as much
solar as possible.

Setting up the system is simple, there's a few parameters but they are
easily understood and the manual is very complete.
The client already had an 8KW PV system using a Sunny Boy 8000TL. That was
already connected to the load panel so we didn't have to do any solar
installation.
The Sonnen Eco uses frequency shift to turn off the inverter. This does not
work when it is grid tied, so it can't stop the inverter backfeeding the
grid, which is a problem for us. There's going to be a fix for that shortly
that will allow us to use a contactor to disable the inverter.

If you have clients looking for Lithium batteries, this is a very clean,
very easy to install and configure system.
I will post pictures after I finish the clean up, we are making a wooden
shroud to hide the conduits.
