Hi. I bought an ''All in one'' MPP2024 in 2020, and never installed it until last week. The exact model is PIP 2024LV-MK. Unfortunately, when connecting it, I made a beginner's mistake. I shorted it . It was late and I couldn't wait to try it. So when plugging it, I made the stupidest mistake someone could make: I connected it in series: 1 cable + with -, and then I connected ... the other cable + with the other - without a fuse ... What a spark it made! (LOL)., and it melted the end of the wire. I changed the melted wire. The funny thing is that right after I corrected my mistake, a fault red light went on. I turned it on and off a few times, and it finally turned on!! :) Then I turned it off for the night. The next day, it never turned on again. The red fault light has been on since that time. For now I reconfigured my 2 batteries in parallel (12 volts) and I'm using my little 300 watts inverter... NB: I'm using it in my small pickup truck's bed camper LOL Anybody has an idea if there's a fuse or breaker inside that box that I could fix myself or I should look to get it fixed by a professional? Tks.

So, you haven't turned it on and looked up the fault code? Doesn't sound good but it may have protected itself and will tell you what happened after which you may be able to clear the code and put it to work.

Actually, the code's been 57 ( Fault code 57 : Internal components failed. Return to repair center.) all the time, but once, and that one time, the code was 51 ( Fault code 51: Over current or surge: Restart the unit, if the errorhappens again, please returnto repair center.)

if you needs parts the factory may be able to send replacement boards which you could install

I don't mind buying parts, but I want to be sure that the part(s) I would buy is the real faulty one(s). I'll wait a bit and look at the answers first. Tks.
 
I am wondering how you have this setup. You do not mention if you have solar or utility wired to it. Follow the manual for proper setup and if you still have fault chances are you will need a new AIO. Getting repairs or parts from MPP is unlikely.

Hi. First, I assure you that I read all the infos about that system a zilllion times before to be sure I wouldn't fuck it up... When I tried it, I fully charged and equalized my batteries first with the grid power before I connected it to the batteries. I've already had my solar pannels (3 x 225 watts), but just not installed yet. Since I bought it 3 years ago (many unplanned things happened since that time which postponed this project), I was kind of in a hurry to try it to see it working ... just like a kid with a new toy... LOL Anyway, it was late, and even if I've been working with car batteries/electricity (as a hobby) for years, I was tired and I did the stupidest beginner's mistake (MY FAULT!!)... So here I am with this problem. I don't mind buying parts to fix it but first I need to figure out what really needs to be fixed... That's why I'm here seeking out infos. Tks.

Hi. Tks for your answer. Qst: What is an ''AIO''?
 
An AIO = All In One
meaning it is a charge controller and DC to AC inverter and Automatic Transfer Switch "all in one unit"
I blew the communications board on one of my MPP units, sent them a pic of the blown board and the AIO serial number and they got back to me in a day or two, walked me through a few checks to be sure ONLY the comms board needed replacement, and for $40 bucks with shipping I got a new board in about 2-weeks.
I have seen a number of comments about "MPP have poor customer service" or "they will never get back to you" - my experience is not at all like that. They sorted out what I needed, quoted a price right away, figured out the shipping, set it up for me to pay electronically, and sent me what I needed in what I feel was pretty prompt service from half way around the globe. Maybe I got to them on a good day.

Edit: the contact email I used/was given: support2@mppsolar.com
be sure to send a pic of the S/N of your inverter and description of what lead to the failure.
In my case they sent me a list of things to double check (to confirm how far the damage had spread) before they zeroed in on just the comms board, and quoted a price and shipping. The board by the way was only $5, it was the shipping to Canada that cost $30-something. I got the new board delivered to my rural address in two weeks from the day I paid.

Hi. Thank you for telling me your expectience. When I bought it, I asked them a few qsts and they answered me right away. I loved my experience with them. I guess I'll have to take it apart... Your answer makes my day ($$$). I let you know guys what was the problem.

Hi. I was running and didn't really see your answer. I'm about to buy a new system so your answer is really interesting. How could I clear that code? Do you know how to do it? It would save me some good $$$ if I could clear it out. WAITING for your(an) answer. Tks.
 
So... how was your summer? lol Anyway the fault code will tell you what the problem was/is and knowing that where to look/repair. In your case, after reviewing this thread it sounds like there's no owner repairable issue that would clear the code. If it were something you could address the fault code would just go away.
Best of luck in the future.

If I remembered well, it was a ''Code52'', ''fault sensor''.... Does that mean something to you?

Also, I took it to an electronc repair shop. The guy (didn't know anything about inverter, at least not in that kind of stuff) looked at it, and told me that he didn't see anything wrong that he could spot in it...
