    SolarEdge Inverter Startup Error New Install

    As I understand it, there are multiple reasons why you might get high-voltage faults. Here's the summary of the issue that I had: we had high grid voltage issues-- meaning that the voltage of our utility/grid lines were about 10 volts too high, which was the root of the problem. Voltage...

    5 Powerwalls not working as expected in Maryland

    Very interesting, I wasn't aware of that feature. Seems like that would be a great way to keep solar production at optimal levels when grid is down and batteries are charging. Thanks!

    5 Powerwalls not working as expected in Maryland

    Alright, with some encouragement from gpez, I tested it out today, and everything worked as I had hoped and as gpez suspected. To summarize: What I was testing: To determine whether or not the gateway would shut the solar down in a grid-outage scenario, where battery SOC was less than ~95%, and...

    5 Powerwalls not working as expected in Maryland

    Oh man, I might just need to test it now-- for science! Monday or Tuesday should be sunny enough here to to reach over 5kw production per powerwall. I'll have to drain the powerwalls sufficiently the night before to ensure they have a low enough SOC by the time late morning brings high solar...

    5 Powerwalls not working as expected in Maryland

    Hmm, I see what your saying, and you may be right (although I hope you're wrong). My hope is that it would behave the same way as it does during a sudden grid outage (while solar production is cranking in combo with the batteries at 100%SOC), where it nearly instantaneously changes the frequency...

    5 Powerwalls not working as expected in Maryland

    Thanks for the feedback. All three of the solar inverters are together on the powerwall side. So, yes, it sounds like I'd run into an issue if the grid is down and the sun is up, and the charging powerwalls plus the consumption are less than the solar production. But, it sounds like it will be...

    5 Powerwalls not working as expected in Maryland

    Thanks nativewolf and jjrandorin. I'm really happy with the system overall. And, actually, we just had a grid outage about 10 minutes ago that only lasted a few minutes, and the powerwalls responded as designed. Very happy about that. So my guess is that the issue that I originally posted about...

    5 Powerwalls not working as expected in Maryland

    Fair point-- that certainly wasn't my intention. I just meant that the powerwalls failed to turn on during an actual outage. But the new title is perfectly fine. Thanks.

    5 Powerwalls not working as expected in Maryland

    Thank you for all your help gpez, much appreciated. It does appear that they've fixed the high line voltage from the grid, so fingers crossed that this will pave the way for smooth powerwall and solar operations down the road. If not, I have some good information to start troubleshooting, but at...

    5 Powerwalls not working as expected in Maryland

    Wow, thanks for all the great information. To answer your questions as best I can: a) Solar was producing 22.5 according to the Tesla app, and 23kw according to the SolarEdge app. b) The Powerwalls showed 100% charge, but as I understand it, it's not really 100%-- so I don't know the exact...

    5 Powerwalls not working as expected in Maryland

    Cirrus, solar production was around 21kw at the time the power went down. And, yes, my guess is that the solar panels did play a role in whatever went wrong. One possible clue I just discovered is that there were several error codes on the SolarEdge inverters, one of which is a "VL-1 Min1"...

    5 Powerwalls not working as expected in Maryland

    Well, not exactly. First, some background, and apologies in advance for the long post. Our five powerwalls were installed last week (after being ordered last March) in combination with our existing 38kw solar array, which was installed this past September. We use quite a bit of power here on...
