Ordered a Skybox

Postby Ampster on Sun Nov 04, 2018 5:06 pm

I just ordered a Skybox from Northern Arizona Wind and Sun. As soon as they confirm a delivery date, I am going to cancel my order for a Tesla PowerWall. Several years ago I had installed a Radian and used it for load shifting. Over the past 3 years when I had power outages I was the only one in my neighborhood who had power. I ran the Radian using a pack from a Nissan Leaf. I configured them as a 6P14S pack running at a nominal 56 volts. When we bought our new home in Sonoma, California we rented that other house and I sold the Radian to some guy in Mexico who is running a restaurant near Cabo San Lucas.

I was never sure the Radian could be AC coupled so that is why I did not move it to Sonoma. I had been following the announcements for the Skybox but it wasn't ready last November when we wanted to get the Investment Tax Credit for 2017. Therefore we installed solar panels with a Solaredge Inverter and ordered a Tesla Powerwall. A year later and we have still not received a confirmation from the installer when the Powerwall might be delivered. Therefore when I saw that the Skybox was out I watched the Webinar and some other videos. I still have the Nissan Leaf pack and realized I could set up the Skybox for a lot less than what the Powerwall was going to cost installed. There are some California Self Generation Incentive Program subsidies but the installer community had jacked up the cost of the Powerwall to almost $12,000 and there were a lot of restrictions by the SGIP programs in terms of whether I could use the Powerwall for rate arbitrage as I had been using the Radian. In three years the Radian saved me $900 and I learned a lot about load shifting and programming the Radian. I loved all the data I got from Opticsre so I am looking forward to being in that environment again.

The other thing that I like about the Skybox is that I can incrementally add battery capacity to the Skybox at around $200 per kWh (in 3.5kWhr increments). As I become more familiar with my seasonal loads I can continue to add capacity. In this house I am on NEM 2.0 and it pisses me off that I have to pay Non Bypassable Charges even though they are only a couple cents per kWh. I am retired and this has become a hobby for me. I call it a hobby because I can rationalize some of the expenditure without having to explain the low ROI or long payback. We are in PG & E territory and could easily see some grid shutdowns because of high winds or just plain old grid reliability problems, which is another reason I don't want to wait for the Powerwall.

Let us know how it goes! A friend of mine just got a Skybox. I'm going to help him install it soon. It looks like a very simple/straightforward install.

Will do. My panel upgrade to 200 Amps is being worked on this week. The critical loads subpanel is up and fed through a gutter so looping through the Skybox will be easy. My 14kWhrs of batteries are ready to go so I am anxiously awaiting confirmation of a ship date.

I read this post and then did a bit of R&D on the skybox. If the model is half as good as as the specs it will be awesome.

Kurt I presume that the units are stackable in single phase and can also be run in three phase?

Well done outback

i just ordered a skybox inverter as well. however, i'm having difficulties getting a hold of outback's rapid shutdown solution or rsd-1 specifically designed for skybox. oddly, i was told the skybox units are available through most wholesale distributors but the the specific rsd-1 was not. anyone having similar issues here? thanks, andrew

My unit is being shipped in 10 days from Outback. As far as I know there are no units in inventory at wholesalers yet. Your mileage may vary.

anyone have any thoughts on the skybox rapid shutdown solution dilemma? i'm having issues finding a way around the 2014 nec code requirements on this. i can't seems to find the specific skybox combiner box (FWPV3-FH600-S2D); my distributors don't have a clue on this but the outback states they have them - not to public at least. am i missing something here? andrew

I am not sure what the dilemma is?

I have some Leaf batteries from another project. After I get a better sense for my loads, I can increase capacity for about $200 kWhr. My first goal is to get through the peak rate period not using the grid.

My Skybox arrived yesterday. I got the mounting plate situated and needed to adjust my lower wireway to accommodate the location of the knockouts on the bottom of the Skybox. Tomorrow more wiring and assembly of my pack. I also hope to mount the main unit if my friend is available to help tomorrow. I still have lots of work including assembling my pack of Nissan Leaf modules.

Initially I will configure the Leaf modules in parallel groups of six and put those sub packs in a series of 6 for a voltage range of 45 to 50 volts. That corresponds to cell voltages of 3.75 at the bottom and 4.16 at the top. I don't know the specifics of the charging parameters so if those numbers don't work I can add another parallel string to increase those ranges by 7.5 volts. Each Leaf module consists of two parallel cells in series with another two cells. There is a center tap so I can check voltage at the parallel cell level. :grin:

great. are you finished with the roof portion? as in, wiring the array for the pv input? did you go with outback rsd - 1 solution for the rapid shutdown?
i'm still waiting on two skybox unit the the matching rsd-1 for each. it sounds like they're still month out. cheers, andrew

Thanks, I was on the Webinar as Rick, and that answers my question there as well. I fortunately have a CAN enabled charger and will plan on using that to charge my pack. I can interface that with my BMS to control charging parameters. I can also set a timer on that charger to charge the pack at my super off peak rate. I am finalizing my set up and I will make room on my backboard for that independent charger.

In the long term I would be happy to work with support explore feasibility of supporting that functionality over CAN bus. Perhaps I need to reach out to Orion to find out if they would be interested in providing the protocols.

Optionally I can use outputs from the BMS to close a relay (contact closure or 12v) to tell the charging function on the Skybox to start or stop. Is there is an input on the Skybox for that functionality? Of course that assumes I can set the charging voltage on the Skybox even if the Skybox is not connected to solar. I am checking all my assumptions now. I expect to commision the Skybox in the next few days and some of these questions I can probably answer once I have access to the configuration menus.

I got the Skybox commissioned, first on just DC battery power. Then after everyone was out of the house I shut down the breaker for the critical loads panel and rewired the grid to the Skybox and the Skybox to the critical load panel. Did the tests in the commissioning diagram and turned on the Skybox. Lights came on and with my internet connection got on to Opticsre and did more configuration. More later. :grin:
