Just a quick word of caution... If you are going to need backup power then just double check that the surge capabilities of these inverters will work for you. I know nothing about the Tesla, but I do know that most of the newer battery inverters like the SMA
Sunny Boy Storage, the Solar Edge StorEdge, Outback's Skybox, and others, often have pathetic surge capabilities. If Arbitrage and/or very small backup is your game then it's not a big deal, but for my projects, this instantly counts them out. Fronius was
going to bring in a battery inverter (I don't know if or when) but their product was going to have the same problem according to the techs at Fronius that I know.</div>

Now if you're comparing these against the SB "Secure Power Supply" then yeah, they can handle a lot of loads, but once you pay out all that money for the batteries, then most of my customers are going to expect a more substantial backup capacity.</div>

</div>
<div>Welcome back, Peter, to the Brave New World of grid-tie plus storage plus SGIP plus bulk services plus plus plus.
<div><br>
</div>
<div>From my perspective, Tesla and LGC/SolarEdge are the furthest along in this new journey beyond the dinosaur designs and strategies of the 1980s to the early 2000s. At least if you look at the installation data from the two cutting/bleeding edge states
of Hawaii and California. </div>
<div><br>
</div>
<div>SMA is somewhat late to this particular dance. That said, I find your comments below kinda shocking. </div>
<div><br>
</div>
<div>Blair Reynolds....are you out there? I've found him to be one of the most knowledgeable SMA guys on the Sunny Storage front. If he doesn't respond, let me know and I'll get you two together. </div>
<div><br>
</div>
<div>Aloha,</div>

<p class="x_MsoNormal">When I was a C-46 contractor in California from 2000 to 2012, I used to do about 1/3 of my business as grid-tied battery backup and off-grid. I came to focus on the Outback solutions in general, and later the Radian 8048 and 240 A-hr
AGM batteries. </p>
<p class="x_MsoNormal"><u></u> <u></u></p>
<p class="x_MsoNormal">That was obviously a while ago. I became an educator and a consultant helping California K-12 school districts become more energy efficient and energy conserving.
</p>
<p class="x_MsoNormal"><u></u> <u></u></p>
<p class="x_MsoNormal">Nonetheless, I had a left-over client that was working through a full-house gut and rebuild. I recommended the most efficient lighting, A/C, fridges. I helped him create dedicated branch circuits should he want to back-up critical loads.
I designed a SMA/LG 12.4 kW roof mount system together with a 400 A 240/120 V split phase service panel. We were ready for battery back up and also told him that there was a new program California SGIP. One-half of his service panel remains untouched.</p>
<p class="x_MsoNormal"><u></u> <u></u></p>
<p class="x_MsoNormal">So with the SGIP Program, I put in a reservation to Southern California Edison for a 8 kW / 16 kWh (Sonnen ECO-16 -- based) smart storage system. The guys at Sonnen made a number of faux pas, so we went looking elsewhere.</p>
<p class="x_MsoNormal"><u></u> <u></u></p>
<p class="x_MsoNormal">I really like the SMA SB inverters. The three MPP inputs, the secure power supply. So I thought since SMA claimed to have a Sunny Boy Storage system that was SGIP-compliant, and had taken this new product on a eight-city road show,
we were in like Flynn.</p>
<p class="x_MsoNormal"><u></u> <u></u></p>
<p class="x_MsoNormal">Fast forward: I have spoken to my sales rep at Wesco, and FIVE count them FIVE -- people at SMA Sales and presales Tech Support , and not one person claimes to have knowledge of the Sunny Boy Storage system. Have I gone blind, dum and
crazy?</p>
<p class="x_MsoNormal"><u></u> <u></u></p>
<p class="x_MsoNormal">I understand that StorEdge product has traction and I am ready to jump ship. What am I missing?</p>
