You cannot use the overkill app to reset the BMS parameters to factory, that's when the timer gets set to zero.

You just saved me some money (and time), thanks!

No issues today.... The battery is at ~57V and all the cells are at 3.57v or so. The MPPT stop charging at 57 and everything looks happy.

So bring 4X series strings down the side of the house, into a combiner box to make 2X SP strings?

Here's a photo I found of one I built years ago.

There's also DC combiners. If you have more than one series string of panels into one MPPT you'll need something to combine things together.

Excuse my ignorance, but I thought combiner boxes were used with Microinverters w/ AC?

Understood. The working range is much lower, 440v. At that voltage, it's ~11 panels per series string. If I series parallel array1...

You are 100% correct. THHN isnt rated for wet locations. I'll need THWN like you said. I will look into XHHW. From what i read in a...

Absolutely. That was quick back of a napkin math. I will confirm the calculations with my electrician before we install!

It worked! The full app has 3x the features of whats available on the play store. It is buggy though. Loading a screen sometimes ends in...

Yes, Yes, No. I checked the connector crimp and the screw tightness. A few minutes ago I swapped cells 7-9 for 10-12. When the sun...

Of course! Already eyeing the EG4 9K!

New issue. Cells 7-9 are over charging. When charging starts, the cells are in balance with only .02v delta. Today after lunch when i...

Indeed. I read how the fans were "louder" than most people anticipated. My inverter was going in the garage which is far enough away...
