    Pfeeeew! thank you so much. That would have been an expensive mistake.

    The SCC has an option to manually set the charging levels. I did so based on my batteries specs. I'll send pics of all of that in the morning.

    Sorry fellas. Pics and accurate stats coming to orrow morning. It was cloudy today and I had to run out a town.
  • Post in thread: Help me diagnose my system

    Yes.
  • Post in thread: Help me diagnose my system

    I'm using a 4 to 1 adapter. I'll do the tests tomorrow and post pictures of every aspect of my system. Thanks a ton for the help!
  • Post in thread: Help me diagnose my system

    Haha, yes indeed. I've been fooling with this for over a month and I am out of ideas. :P
  • Post in thread: Help me diagnose my system

    I'm also curious about the science behind over paneling. My SCC can accept 1300 W when on a 12 volt battery bank. My understanding is that if I go over that it simply limits it and only uses what it needs. As long as I stay under the 100 amp 150 volt SCC limit, there is not a problem. First...

    Yes. 12v The 80-100a is what the SCC is pushing to the batteries. I'm not sure what the inverter is pulling. I assumed it just does it's own thing with the 12v bank. I'm curious to see. I'll let you know what that reading is.

    Okay Fellas. Here are the accurate specs. I was a bit off. :( I apologize for the bad lighting in the pics. They system is in the basement of my off grid cabin. This is all run similarly to the system that was here when I bought the place. I have simply been upgrading components. Once I get the...

    We live off grid and run a portable AC unit, chest freezer, fridge, water pump, lights, computer, etc.
  • Post in thread: Help me diagnose my system

    Alright. I have confirmed that the panels are good. They are producing at about 70% I replaced the audio cable and another undersized wire I found. (In retrospect, I should have redone everything instead of keeping the old wiring) As of now, I have two more questions. 1. I have a 6 AWG wire...
  • Post in thread: Help me diagnose my system

    I need help diagnosing my system. It doesn't seem to be putting out the power it should. System is as follows: -2,600W solar array ( 8 panels each are 325w-10a-40v panels) -Renogy Rover 100A MPPT Charge controller - 12v 600ah lithium battery bank - renogy 2000W inverter Wiring is good...
  • Post in thread: Help me diagnose my system

    My batteries are at 40% Under full load, 800w ac unit, I only get 350w max output from the array. And yes. The inverter is a 2000w inverter.
  • Post in thread: Help me diagnose my system

    I have not noticed them getting warm. I'll check.
  • Post in thread: Calculate acceptable over paneling.

    Thank you everyone for your helpful replies. I'm seeing several places in this thread a mention to an ISC of 40a for the SCC. The SCC I am using is the Renogy 100a MPPT The specs are as follows: -Nominal Voltage: 12V/24V/36V/48V - Rated Charge Current:100A -Max. PV Input Power: 1300W/12V...
  • Post in thread: Help me diagnose my system

    Their volt reading is always fine, but the amps always seems low. Regarding the wiring, what would you suggest? For instance, on the PV run? There doesn't seem to be a safe way to size up from 10AWG. But sizing charts say I need larger that 10AWG if I want to stay under 3% loss. For example. My...
  • Post in thread: Help me diagnose my system

    Yes. I live in the UP of Michigan so I need to be over paneled to survive the darker winters. I would agree with you, however, even at peak sun and depleted bank, I never see 1400w.
  • Post in thread: Help me diagnose my system

    I have four sets of two panels. Each set is wired is series and the four sets are wired in parallel. That final positive and negative go through a fuse breaker and then directly into the charge controller.
  • Post in thread: Help me diagnose my system

    Panels are clean. No shading all day long :) Angle is 35 degree.
  • Post in thread: Calculate acceptable over paneling.

    My system: -1300W Trina solar array (4x325w panels) 40v/isc of 10 -Renogy Rover 100A MPPT, rated at 100A/150V max pv input. Also 1200w at 12v max pv input. -12v 300ah battery bank -Renogy 2000W inverter I am trying to increase my solar array. I can easily wire 8 x 325w panel in series...
  • Post in thread: Help me diagnose my system

    That's super confusing. Haha. In the SCC settings it has an option for Lithium. So, that's what Ive set it to. My battery have a 200a bms
  • Post in thread: Help me diagnose my system

    Sure. What do you mean by Core?
  • Post in thread: Help me diagnose my system

    I definitely understand how having the wrong charge controller may be affecting performance. But that wouldn't affect performance at the panels would it? When I take readings at the panels the amps still seem super low.
  • Post in thread: Help me diagnose my system

    Thanks for that advice! I will do those tests tomorrow. My understanding about over paneling from talking with other members on this forum is that as long as I do not exceed the Max amps and voltage allowed by the charge controller I am okay.(200a and 150v) I currently have the charge...
  • Post in thread: Help me diagnose my system

    Okay, I understand that. If I separated a single panel and unhooked it and tested it with a multimeter at peak sun, should I expect to see around 40 volts and 10 amps as the sticker says? I just did a test like that today and I am getting 40 volts and 2 amps. I have tested each of my eight...
  • Post in thread: Help me diagnose my system

    Okay. I will test the panels. Yes that is audio wire. I had forgotten about that. I have the correct stuff. I'll swap it out. By tapping, are you referring to my little clamp on the left positive terminal? That is from an AC charger that I am not running at the moment.
  • Post in thread: Help me diagnose my system

    I'll double check the sticker in the morning and send pics.
  • Post in thread: Help me diagnose my system

    Okay. Pics coming tomorrow evening. Thanks a ton!
  • Post in thread: Calculate acceptable over paneling.

    Thanks for the help. That clarifies a ton! When I upgraded the system, I was going to upgrade to a 24 volt battery bank. I am currently using 2 12v 300ah lithium batteries. My understanding was that wiring them in series for a 24 volt system would save me when it comes to cost on charge...
