  • Post in thread: Testing grid tied inverters

    So yes, I was focused on the manager and still am so OCD for sure :). I still plan on getting up there but messing with the manager is something I can do from my desk. It turns out, they trashed the operating system somehow. There were entire directories removed, permissions messed up. I'm not...
  • Post in thread: Testing grid tied inverters

    I'm willing to mess with it because I have the time to so it's worth doing rather than jumping into yet another costly investment into something that has not paid off yet. I don't mind making the investment but I'd like to see where I can get with this. I have at least 20 spare inverters so if I...
  • Post in thread: Converting grid tied to DC

    Just wanted to acknowledge your great reply and will need a little time to absorb this :). The reason I don't have a set plan for what I'd like in terms of battery reserve is because I figure at least a 1000 watts overnight would be useful. A couple thousand watts overnight until the sun came...

    The sail has wind... just not enough :). I'm not sure what you mean by getting it running vs fixing it? I have to fix it to get it running and that's what I'm slowly working on as time permits. It's neither obsolete nor dead, it's generating 3KW now which is better than the 0KW it was doing...
  • Post in thread: Testing grid tied inverters

    I searched the net and read a number of posts but nothing gave me a clear ok to go ahead so I thought I'd sign up, say Hi and ask my first question. About three years into owning this system, it started having problems. The installer eventually left me hanging so now I'm wanting to learn what...
  • Post in thread: Testing grid tied inverters

    Hi, sorry for the delay, it's been a week and a half. I finally got out there yesterday but it was a wasted afternoon. The canopy is on a very steep hill, making it difficult to get much done. Likely why the installer left us hanging. Anyhow, as my image shows, there are four strings, 2x10 and...
  • Post in thread: Converting grid tied to DC

    I thought I did answer that and included lots of information about my setup. As for batteries, I don't know yet, it depends on what my options would be. Since it's mainly for emergencies, then I don't need to power the entire house, only critical things like freezer, refrigerator, lights, pretty...
  • Post in thread: Converting grid tied to DC

    The coldest recorded temperature for my area is -23°F (-30.5°C), which occurred on January 7, 1971. This is the lowest temperature ever recorded and extremely rare. The average during the winter months is typically around 20-30°F (-6 to -1°C). The point is being lost. I don't care what the...
  • Post in thread: Testing grid tied inverters

    Looks like you'd have 1 off on breaker 3 and 2 off on breaker 4. I'm not so much confused as I am new to it and is why I'm asking for input and help so I can learn more about the aspects I don't know yet. With everyone's help, it gets clearer all the time. Today, I'm thinking I should call...
  • Post in thread: Testing grid tied inverters

    At the time, the installer told me the panels (Mage) were no longer being manufactured and the company had filed for bankruptcy. The inverters were also no longer or hard to get until more would become available. When I started seeing the signs of the installer leaving me hanging, I started...
  • Post in thread: Testing grid tied inverters

    For 42, I think it'll be more than a few hundred bucks but I've not looked into that yet. Have not had much time to spend on this since I last posted. Also, because of the way the system is behaving, I have a feeling that the problem might be more about bad connections or something along those...
  • Post in thread: Testing grid tied inverters

    Yes, they have PLC communications, it's how I'm able to see what's going on using the manager which has been very helpful before I get up there. I do have a drawing in this post, it's much earlier on, the first page probably. I left some open areas where I'll enter information for each...
  • Post in thread: Testing grid tied inverters

    My overall consumption actually went down since I installed this. Initially, I was using almost 5000 watts of power 24/7 running a software development environment but over time moved most of that away and down to around 1000 watts now. I always had excess generation so was able to see that...
  • Post in thread: Testing grid tied inverters

    Let's see if I can answer everything. It's exactly as shown in the PDF I share but I have more panels of course. There is a small black box (#2) glued to the panel then that connects to the inverter (#1) which is mounted to the panel. Each panel is the same and each panel connects (#5 and #3)...
  • Post in thread: Testing grid tied inverters

    >What you're looking for in microinverters that produce different current/watts compared to others. >Then with swapping of wires, you can determine if PV panel or inverter is faulty. Ah yes, note down each, looking for variations on the output side. I think that was mentioned but a bit lost by...
  • Post in thread: Converting grid tied to DC

    The installer left me hanging with the system all messed up so I've decided to take it on myself. Can you expand on how it was the wrong decision? Do you mean by the installer or myself buying a grid tied system? At the time, I didn't know the difference and the seller never bothered to tell me...
  • Post in thread: Converting grid tied to DC

    Sorry, I thought my mention of 6KW inverter/s would define that. >In the he winter we have less than ten hours of useable sunshine so 100O Watts for 14: to 16:hours is 14-16 kiloWatt hours Perfect. So, the minimum I am after is 14-16KWhs. That said, I'd like to be able to add as I can afford.
  • Post in thread: Testing grid tied inverters

    The panel has a small box mounted/glued onto it. From that small box, two +/- MC4 or Helios connectors connect into the inverter which are 48V DC input. So the panel must be DC output Unless I'm missing something?
  • Post in thread: Testing grid tied inverters

    That's a good catch and worth chasing. All of the ones which are 112200 have 0 watts and 0 power output. There is no information what so ever on how to do all this from the command line and I see no options in the manager GUI/web interface either. Meaning, I'm not sure how to upgrade their...
  • Post in thread: Converting grid tied to DC

    The panels are Mage / Powetec Plus, 250 / 6 PL US AC. I think I posted a ton of details in my first post. I also mention again that I have shading issues. This is how my setup looks, two canopy's, not on the roof. Very hard to get at the higher panels. This would be as if looking from above...
  • Post in thread: Testing grid tied inverters

    I paid nearly $50K for this setup so the least I can do is invest time into it before pouring more money into it. Right now, I'm pretty convinced the main problem is a software one and not necessarily a hardware one. I simply don't agree with your thoughts of junking everything. That is a...
  • Post in thread: Testing grid tied inverters

    I've never seen lightning remove directories on an embedded system but I've seen plenty of lightning damaged hardware. The directories removed were the ones that the startup program needs to start all of the PLC code. Really not sure what's happened here but happy that I've now got a couple of...
  • Post in thread: Testing grid tied inverters

    What's wrong with these ones? People seem to know what they are talking about. I've had some luck regaining the system so I think I'm on the right path thanks to some of the help here too.
  • Post in thread: Converting grid tied to DC

    First, yes, I'd love to stop arguing about the power company. I've been run through the mill by both the installer/seller and the power company so am not going to be seeing either of them as lovely. I see the installer as a crummy crook for leaving us hanging after making their money and...
  • Post in thread: Converting grid tied to DC

    @TorC, thanks for all the information. I'll spend some time digesting that as soon as I can. @zanydroid, >Are you planning to do DC to code? EG comply with rapid shutdown, etc. Well, that's partly why I'd like to do something where it's not grid tied, so I don't have to think about or deal...
  • Post in thread: Converting grid tied to DC

    I've not found my notes but I think I was somewhere in the 20KW to 30KW area at the very top end IF I wanted to run as much stuff as possible. However, that was my thinking about running a 2kw/3kw hardware rack on batteries overnight. My thought was that I'm making such a little return on what...
  • Post in thread: Testing grid tied inverters

    Anyhow, in the end, no one really responded to what I was asking which is how to actually bench test each inverter individually.
  • Post in thread: Converting grid tied to DC

    BTW, I also posted many times hoping to find someone who knew the manager software and more specifically the Pantheon inverters. I think their problem wasn't hardware but software related. I hoped to find someone that could help me but even reaching out to old employees, no one would talk about it.
  • Post in thread: Testing grid tied inverters

    I ordered that because I thought the panels are 48V DC output into it's own. The various cells I thought are connected into the little box glued onto the main unit. That should output DC I thought. That smaller box goes into into the inverter which outputs AV. It seems the doc I have is...
  • Post in thread: Testing grid tied inverters

    Yes, I bought a current meter and cables to tap between the panel and the inverters (H4). Each of the inverters has a Y cable that is connected to the next inverter so there are no free plugs. However, I made up a connector so that I can tap into the output so could clamp on those wires. I'll...
