SunGold Inverter

Hi,
I was wondering if anyone had any experience with this manufacturer, and if so how well do they work. I was also wondering if there might be a manual available somewhere as well. I am looking for a simple solution I can mount on the wall, and not have too much maintenance. Any thoughts or suggestions for something like this that is at least 10Kw would be appreciated.

SunGold is generally believed to be made by Yiyen or Sigineer. Sigineer is believed to make the AIMS line of inverters as well.

Both Yiyen and Sigineer are generally regarded as reasonable quality for the price.

I recommend you use the search function for "sungold" and read several of the posts to see if anything stands out.

I *KNOW* this unit is made by Sigineer:

Heh. Well, it's based on claims made by both Sigineer and ECPC, so if both of them are saying it's made by Sigineer, I have to accept it as fact...

not bad..I have the 6000w version. zero problems. good quality so far.

Hi,
Thanks for all the replies and information. In looking over the documents I found yesterday it seems to indicate that the PV panel input must be at least 60V. I plan on using 48V PV panels so I was wondering if anyone knew 48V panels would also work or if they had a work around. Just seems odd not to support a standard panel voltage. I tried to upload a manual I found. It was too big.

48v solar panel usually produce 60v or more so they should be okay. so 12v x4in series will work. but why you need 12kw inverter ? what are you powering ?

This is an MPPT controller, and it's just plain lame. 40A means it's only going to do about 2kW max PV.

Voc of your series panels must be < 105V and allow for cold weather voltage spikes. In the Resources tab, there is an entry for temperature vs. voltage factor. A suitable charge controller for this system is more likely to have a 150V max. If you properly feed this beast, you're probably going to need 2-3 more charge controllers anyway.

60 cell panels are likely your best option - 2 in series with as many as you can fit in parallel. 72 cell will likely be too high on Voc and allow for cold weather spikes.

You want your Vmp to be about 50% above nominal battery voltage if possible. That's going to be hard to do with this controller.

I suggest you take the advice of the manufacturer and "disable our solar controller, and connect with external solar controller."
