I am sorry for your loss. Just to clarify for other readers and emphasize what others have said, the cause of the fire was the arcing...

RULE #1 ! NEVER BUY ANYTHING TILL YOU HAVE A PLAN !!! Sounds like everything you intend to run is 120V. I strongly suggest you get...

If you're trying to run all that I wouldn't even think of anything less than 48V. For your inverter size you really need to look at...

And the other options you mention are also possibilities. The OP has not mentioned his use case and how much energy he wants out of his...

If you have 2 panels now, you can make the system work with 2s to start. To add on, don't need same model, just similar Voc & Vmp. A...

Yes and you are not even getting close to your goal of 2100 Watts. I did not see the NOCT on those panel stated but making a wild ass...

That is what I did for both my GT installation and my battery installation.

In my case in the County they had a pre plan check reviewer who helped with a bunch of nitpicks so that my permit ulimately flew through...

+1 for hiring out the plans. I have a lot more fun buying stuff, outlining the approach, and putting it together than doing the detailed...

I should have remembered that. Fun fact: -40C = -40F (= 233K for completeness).

-0.35%/degreeC For quick conservative answer, I assume +16% in voltage, Voc x 1.16 That comes from -0.4%/degreeC and -15C (vs. +25C...

No doubt, and if I were a utility scale facility I could bring that cost down significantly as you pointed out in another post.. But I...

I like this test the best, you can drill and tap 1/8" or 1/4 NPT holes in the pipe and screw plugs into them to seal them off...

How quickly does it bounce around? Sounds like a bad connection in the wiring from that cell to the BMS.

There are a few possibilities at play here: 1) Runner cells which can "Race UP or Drop Fast" very fast once outside of the working...

My drive for solar started with just battery backup for wifes cpap machine. Then I thought how do I recharge them if something happens...

In my case with a SolArk, some DC coupled solar helps stabilize my performance when the grid is down. I have 9kW of AC coupled solar and...

I love your 2nd point. What price can you put on having some peace of mind? Your third point is also a very strong one. Most server...

THE most important factor.

Make sure the busbars are flat with no burrs. They are stamped and some aren't flat. Clean everything with acetone. Put a thin layer...
