Sorry to hear about the bad situation you've been put in. Any update after the firmware update? Although it doesn't sound promising based on Clint's response above. Likely unrelated, but it's worth mentioning. I believe likely have the same Sunpower 435W panels (SPR-E20-435-COM) and some of...

It should be perfectly fine, as long as it's grid tied as excess can be bled off to the grid. If off grid, there's nowhere for the excess energy to go (if the batteries are full), the LUX will not be able to shut down the AC coupling that quickly. You'd need a dump load if off grid and the...

If that's total cost with fees and shipped to your door, that's fantastic! In fact, I'll build another battery or two at that price! If not, then I guess you paid more than $105. :unsure:

Thanks Tim!

If running separate conduits for AC and DC conductors, how far should they be apart if in the same trench (recommended depths for each)?

I think I've seen someone post a link for reasonable raceways somewhere here, anybody have a link? I believe they were 10", but folks were shimming them out 1" with success with the 15k. Has anyone installed a SA w/o using a raceway?

I'd add excessive idle consumption to the list, although for everyone's sake I hope the reported numbers improve with updates or usage.

I just saw this after I posted. It would be interesting to see this verified with a clamp meter. If accurate this looks like it's less than half of what the SA 15k is using? If so, that's impressive!

Has anyone put a clamp on theirs yet to check idle consumption?

Use 6ga back to the existing grounding system? At some point I may add a small sub-panel at the detached dwelling. If so, can I just tap into that same ground conductor back to the main ground?

Congrats on the purchase! BTW, I believe the SA 15K has a max VOC of 500VDC @ 26A, IIRC.

Not to mention you'll likely not want to use 100% of the batteries on a regular basis. So using only 80% of the 10.24kWh batteries, the inverter idle consumption drawing about 2.76kWh/day, and your efficiency losses... You're looking at about 5kWh or less of actual usable batter capacity left...

Like (many?) others, I'm still a little fuzzy here regarding what's required and what's actually best practice. In my case, I have my main panel (with grounding rod nearby) at the house. I have a detached structure roughly 50'-75' away with my DC PV panels on top of it. In this case, does it...

Don't forget to include payment fees for your payment method of choice. This can add another 3%-5% or so (IIRC), I don't think I'd ever consider buying anything from China without some payment protection (via CC, PP, etc).

Keep in mind if you have a smart meter on your house, it will probably trigger some type a warning or tamper alert on the meter (which will likely be sent directly to the utility) if you back-feed the grid. If you still have an older analog meter, no real concern in that respect.
