Finally got around to swapping panels today and success! Not too bad on my 30A controller. Glad to be back up to full production.

Not getting started a few years earlier!

Pre-forum, I wired 3S 72 cell panels on a 150V MPPT. Fortunately, I learned BEFORE the winter temps pushed voltage > 150V, so this was...

In that case, just Voc of all panels should identify odd man out. I had 5 bad panels out of 18. 3 of those showed up by Voc or Isc. The...

I did voltage measurements on the 2S that was low. One measured 35Voc, the other 29-31Voc. I checked Isc on both and they were both...

And here is the second set. Me thinks we have a winner. So can I use a diode tester to get some readings off of these to see which is...

Here is the first set. The drop to zero was breaker off to make the change and reset the MPPT to track again.

Alright, here is what I am seeing. Started charging my car again. fullish sunlight. Batteries started at full. Here is the solar voltage...

Sun is setting now so I can try the separate string thing tomorrow.

No. It is a 2S2P setup as well FYI. These are BenQ panels. I need to find my picture of the data sheet.

I have a small 4 panel string that Voc is 66V. When a load happens (charging batteries, discharging to car) the panels voltage on the...

There is a small 2 CFM drop in what I want to replace it with. I plan to move the inverter to a better location this season as well.

I was doing maintenance on my setup and wanted to see if I could run with the higher output into my EV so I cranked the input of the EV...

For peace of mind, you might just want to get a second charge controller. Having two charge controllers gives you some redundancy. If...
