I have this exact disconnect and have an anecdotal story about it... Electrician was landing some circuits in the main panel (also the same exact panel as you). He was working live and with a slip of a ground wire, POW! It touched a bolt of the bus bar. After a bit of troubleshooting, we found it blew one of the 200A(
) fuses in the disconnect. One heck of a short circuit. Of course, this was Friday at 3:15pm, before a long holiday weekend. No area supply houses had that fuse in stock. Closest I could get was 150A, which at least got us running again. Note, we were able to run off-grid from the 15k, just couldn't use the grid, due to one leg gone.
^ Moral for me - Order one or two of those big fuses for backup. This stuff shouldn't happen, but when it does, it could be at the worst time.
Also Ryushin, I have been researching (and have posted a couple other places) for how to solve my needs. I have 22 more panels I'd like to AC couple to the 15k. Another inverter would be great for several reasons, including having a "backup" to the 15k. I couldn't find suitable inverters until I came across this thread. Thanks very much!
Here is what I am deciding between:
- Growatt MIN11400TL-XH-US: About $1000 after tax credit.
- Solis S6-EH1P11.4K-H-US-RSS: About $1400 after tax credit.
- Sol-Ark 15k: About $4150 after tax credit.
Main thing I don't like about the Growatt and Solis is that they are HV battery, with Growatt only theirs. Solis can do others. I have 48v Homegrid batteries now, so those two inverters could not charge my batteries. Of course, the 15k checks all boxes, but is $3k more.
As you did, I will run this by the home boss. Perhaps she'll just say "what the heck, just get the 15k."
