tl;dr: a projectile hit one of the panels on the string and that was the cause of the observed power output behavior. Long version: So I forgot to update this thread. The installers switched the string from M1 to M3 and it didn't work 100% either. I mean, it did work 100% some days (including...

Update: I did the power cycle, it seemed to have improved, but for just under a week. Same thing happened last night: M1 suddenly shows 100V at 10:00pm, voltage stays high, and in the morning it started producing 3 hours after M2 did. I contacted the installer to help me for next steps. Our...

Well I guess that makes sense, don't know why I didn't think of that. Even washing machines need to be rebooted once in a while nowadays. I'll try that at night to not disturb the output (I might not be able tonight though, but will do soon and I'll report back). I've never had to reboot this...

Hello! I have a Sol-Ark 15K with two strings connected, one in M1 and the other in M2 (so I have an empty module). I have 4 rows of 6 panels each, 24 panels total, each with a Tigo module. IIUC (I didn't install this myself), the first two rows are connected in parallel into M1, and the second...

Got the answer! I had written an e-mail to Sol-Ark earlier, and got this response: When I asked "Can you clarify what will happen if I attempt to connect the 120V generator as shown in the diagram", the response was a bit better: So I decided to go ahead and try it out during the night. As...

Ah thanks, I didn't know that, and just saw in the manual that in a case like that, it'll produce error F26 - BusUnbalance_Fault. I think it shouldn't apply to me, because before attempting to connect the 120V generator, I would first disconnect all AC load from the Sol-Ark, so no AC would be...

Thanks! Yeah I think so too, but maybe someone has had a similar set up before and can let us know. There's a section near the end of my Sol-Ark's manual called "Troubleshooting Phasing Issues" and says that That makes me a bit nervous. But I'm also not sure if it would categorize the...

When I open the cover, I don't see any breaker for the grid input in my 15K model. I only have 2 battery breakers and a load breaker.

Here's my best try at ASCII art: ______ _______ Grid--|SW-1|-out------grid_in-| Sol | -| | | | Ark | Gen---|____| | |_____| | |load_out | | ______ |...

Well, I don't know much about power in general, so I'm not 100% sure about all this, but it seems to me that ahead the Sol-Ark, we only have: 1. Grid input via power meter 2. 100 amp main breaker 3. A transfer switch with a Ditek surge protector (which I can use to disconnect the Sol-Ark from...

I've experienced the built-in breakers in the Sol-Ark; it has disconnected before because of over-voltage on the grid (it was measuring more than 132V per leg for many continuous minutes). I can ask my installers to install a switch ahead of the Sol-Ark, but I'm wondering if it's necessary, or...

Hi all, I just got solar installed with a Sol-Ark 15K inverter and HomeGrid stack'd batteries. Before all this, I just used a little 3kW, 120V Honda inverter generator. During an outage, I'd simply connect it outside and switched via a transfer switch that's outside the house. Of course, no...
