Good Day power forum folks.

I have an 8kw inverter, I always thought it was a DEYE but now I am not so sure. I want to purchase another inverter to add in parallel. the 8KW works amazingly well but I have noticed that sometimes during the day we draw maximum power from the inverter. I don't like running it at max power and therefore want to add another in order to reduce the load and ensure longevity.

I have attached pictures of my unit , it is a rebranded product. We bought the house with it installed. the company that sells them is in PE but they apparently only supply to farms and they are not interested in helping me. I also attached pictures of the label as well as the HMI and main version software that is loaded on it. HMI Ver339 Main Ver3870

There is a person who wants to sell their DEYE 8KW because they are upgrading but there software and Main version looks completely different to mine. (Picture attached) HMI Ver 0000-C35A Main Ver 0-6012-1724

My question is this, are these 2 inverters compatible? obviously one or both of them the firmware will need to be updated to do this.

Please help me with this. If they are not compatible please tell me which inverter will be compatible.

I don't want to go and replace the inverter if it is not necessary.

I know the cabling is a mess currently. I am busy prepping for the 2nd invertor

If the model numbers are the same, they should be compatible... Not sure how you will get them on the same firmware though.

Worst case scenario, just split the load circuits between the two inverters.
