SunGold SPH10K48SP 10KW 48V SPLIT PHASE SOLAR INVERTER

My 10Kw SPH10K48SP has been dead out of the box. Constant 05- alarm. Battery overcurrent hardware protection. Nothing connected except the battery. Smells a bit burnt. Sungold keeps pressuring me to take it apart and break open the sealed connections but I think that's a bit much to ask for a brand new unit. I can't get them to offer a replacement and my (new) unit is dead on arrival. Not a good experience so far.

@britguy59 Sungold did mail me a replacement, received today. I am up and running better than ever today. Hang in there I’m pretty happy they made me whole, I think they will you too 7D6D2BFF-F866-463E-BB82-21D59207506B.jpegDED7A253-BD2E-4C24-A9F8-BD6BCE30430A.jpeg

UPDATE.
The Second replacement inverter also had issues. I was sent, and replaced, the POWER board. Not too difficult, actually not as bad as I thought.
Fault continued, (different one) and they sent me the OTHER main board, the INVERTER board. I replaced that too.
It works!!
So both main boards have now been replaced. Looks more complicated than it is. Biggest concern was the white goop they like to seal the plugs in with. Comes off pretty easy.
Only a few small ancillary boards left of the original device.
All tests so far have been good.
The takeaway is this. It's been a nightmare, taking over 4 months to resolve. HOWEVER, I will say that Sungold responded within 24 hrs of every email I sent, and sent new boards within a few days. While support is odd, email only, they have at least stuck with it and were prompt. If you have issues with a Sungold inverter, don't waste time asking for a return and replace. They like to send you parts (cheaper) and its not that hard to repair. Take this experience as a lesson in the system they use. I did end up with a working inverter.

Glad you got things working, but damn, what a pita and certainly not customer-centric!
I doubt I'll buy additional Sungold products in the future just due to their poor customer support.

Keep us posted and what is your system configuration?

Very nice did you document or photo any of your board replacement work? The forum could really use that info.

Thank you for your update, glad you are up and running and more knowledgeable now than most of your machines internal workings

I have this unit and 6 100ah 48 v batteries. Can anyone tell me why the inverter cuts the output power when the batteries get low, even though they still have like 20-30% charge? This keeps happening and I’ve gone through all my inverter settings to see why it might be doing this and can’t figure it out. It seems like it’s a threshold issue but nothing is adding up. Getting fault code 63, which is under voltage alarm.

Well on mine its the battery undervolt setting that does it.
 
I started hooking up my second 10,000 W inverter in my kit, I have 20 440 W panels connected to it, but when I hooked the panels to the inverter, the inverter does not fire up like I would expect it too. Thoughts?

How are the panels wired?
Did you verify voltage and polarity were correct before connecting? What was the voltage if yes?
Do you have a battery connected?
Is this/these inverters linked?
And this.
 
My system came with 2 10k watt inverters, 6 batteries and 32 panels. I have 1 inverter with 12 panels and the batteries up and running while I build my shop which will house the full system when ready. The shop is now up, with the remaining panels on the roof, and I hooked up the second inverter to it, with the remaining 20 panels linked. I have since discovered that my volt meter I was using was rated to 300 v, so when I tested the wires from the panels (at the inverter) it read -001, which I assumed was no power. I found out that the panels actually were just fine and it was way over 300 v, so the meter wasn’t registering. I also learned that I had too much voltage hooked up to the inverter, which I think fried it. I had all 20 panels going to PV1 input. It seems I made a very expensive error..😩. I have since put 10 panels to PV1 and 10 panels to PV2, but I think it’s too late. The inverter is not coming on at all…

My panels are over 300v on the 10kw inverter in question which is fine since its rated at 500 volts max.

Were all 20 wired in series?
The first 12 panels, how are they wired?
If they are all in series I would strongly advise changing them up.

We need to know the VOC of your panels.

Did you try powering it up with a battery or grid connected?

Yes, all 20 of them were positive to negative etc, then to the inverter. This is exactly how the first 12 are set up with the first inverter and are working fine (I think)🧐 I am not connected to the grid, and I haven’t tried adding batteries yet, as they are all hooked up to the other system. We should be moving the rv under the cover today, so I’ll merge the systems, and put the batteries on the 20 panels…

Here are the panel stats... Yes was over on 20s. 10x2 would have worked with some clipping potential. OV bad, OA not so bad. 12s is too close for comfort on a perfect day.

I don’t think I can hook up my panels in series, the voltage is too high. I think I’ll have to connect them in parallel to stay under the 500v limit. That’s a lot of wires with 32 panels.

I took one of the batteries from the 6 that were on one inverter and 12 panels and connected it to the other inverter I have connected to the other panels. I hooked up two strings of 10, one to each PV input. The inverter actually worked, I couldn't believe it, I thought I’d ruined it. I thought the voltage limit of 500v was per PV input, but I don’t think so, I think it’s 500 total. So that means I’ll have to rewire all my panels in parallel to stay under 500v. Good to know, but a pain to do, the panels being up on the roof and all screwed down…

Good news!

It is, 500V and 22A.

I would reduce your 12S string sooner than later if I were you.

It's good to see SRNE has over voltage protection, actually impressive for the ~800V you were sending to it.

Currently I'm running ~350 VOC, ~20A on 1 MPPT; 280VOC on ~22A on another. I see frequent clipping at 5500W.
I'm working on a third string that will be ~400VOC, ~10A for another MPPT.

Are you sure it 500 per input? Where does it say that in the manual? I can’t find it. I would love it if you’re correct. What is “clipping”?

In the back of the manual in the datasheet it says
Number of MPP Trackers 2
and MPPT Voltage range 125-425 (with a max of 500)
