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

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 around 3A. I have 6 spares available. I think I will swap the lower voltage one out for another. Will verify the voltage on it before beginning to see how this goes..

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 the issue? The second voltage drop was me flipping the solar breaker a second time just to make sure the MPPT got the hint.

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 trend. Going out to seperate the 2S2P into 2S now.

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 SCC drops to 37V. The other SCC with similar panels only drops down to 55V which is closer to what it is supposed to be. I thought it was connections and changed...

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 to 12A at 120V to see how everything would work. While investigating the system for any hiccups and such, I noted it was really quiet. Both fans on my inverter...

What is the exact model number of the charge controller? Some of the BP cannot take the 77V input.

I have been up until it was in the 110 range then I had to drop the charge rate to 8 amps. I did that for about a week then only charge on 100 degree or less days. It seems to use 4kWh a day so I like it. I have 6 more panels to add so more capacity on the horizon.

So I am not moving this seasonally, I am moving it to be better protected from the elements. I used this to power a computer and some networking equipment as well as charge my electric car using L1 charging. This will move it closer to the source of where the power is being used, help protect it...

I am moving my setup at the end of the hot season from my back screened in porch to inside my garage. Beyond any cable adjustments and using backer board on the walls, what are other things to look out for? Also, since I am in the garage and the house grounding pole is there as well, is...

I did as requested and it was still loading the previous driver. It seems as though it was forced as the new driver wasn't fully installed. I believe I completed the install now, but it is giving the "not a modem" error. I think there was a command I needed to issue to make it fine. I can't...
