That’s a lot of Sunsync inverters getting repaired. Aren’t these supposed to be the rolls Royce if inverters?

 

[denmendez65]

It’s rebranded SJY afaik. SJY is a major lipo4 producer/supplier in China from what I had researched. Been around for a long time also so should be good.

Just the BMS I would worry about.

Looks like different inverters. Came up on my stories.

I think I saw a thing with the screens on the Sunsyncs packing up. I suspect that’s is what the volume of them is about.

What do you mean? The battery comes with a datasheet. It’s half Chinese and half English.

Are you talking about the battery?

It had multiple posts on the story/advert. I just shared the part of the advert with the Sunsyncs that stood out

You were talking about SJY out of nowhere.

Yeah I don't know hey. If I had bought a very expensive inverter like that and it broke I would be angry.

I see an installer on facebook complaining saying he won't recommend Sunsynk anymore because warranty claims take very long.

Oh that, thought you might be talking about the one with 6p cylinder cells with faulty cell 8. How do you know cheapig is SJY? You say it like its a bad thing?

10 year warranties are a nice sales pitch.

It’s a good thing. SJY seems to be a good brand.

How do you know its SJY.

 

[cavedog]

He actually recommends Deye now. If the inverter fails they give you a loan unit and take 2 weeks to repair or replace.

 

[denmendez65]

D

How do you know it’s SJY.

Datasheet they come with
