Sunsynk (DEYE) Hybrid Inverters

Looking at the Acrel on the Solis this is how it is wired up so should be a straight swap.

Great find by the way - mine worked out about €700 cheaper with the German seller vs next best I could find

I'll be terribly honest, was spooked by the some of the (albeit very few) bad reviews from that ebay seller so was going to wait to see how each of you fared. On seeing one of you getting the goods and others getting tracking #s, just pulled the trigger myself on an 8K Deye with 5th-10th Dec delivery. Lets see how it goes!

Very straightforward setup?

Looking back through the pages of this thread, it appears a few have had issues with noise, especially the 8K version, which is not what I want to hear (so to speak). Some saying a high pitch coil whine type sound. What kind of decibels are we talking here? Sound of a noisy bee or sound of a hand drill? Will likely be storing it in the shed anyway but still would rather not have a buzzing noise come from the shed.

Also, how does the inverter ramp up voltage from the battery without a transformer? Seems like witchcraft!

Yeah it's one of my reasons for moving the new inverter to my shed. I think noise is more from the fans and the electrical is not an issue. Maybe some younger people with very sensitive ears are the ones affected by the electrical noise. I think in the shed you would be totally fine though...

I assume there's a similar level of noise when charging the battery?

Got ours yesterday as well, a substantial lump of a thing.

Have a bit of work to do before I'll get a chance to get it installed so probably looking at the new year.

As I will have to split the strings I'll need to get and fit a new fireman's switch as well.

Not the most intuitive of instructions for the setup so if anybody has any pointers that would be great.

Thanks.

Just looking through the manual. The wiring looks reasonably straight forward and could probably do a lot of it myself. How much of it do people generally do themselves or does it depend on how much the electrician is willing to allow? Probably best to discuss it with the electrician first. Don't want to buy in all the wiring/fuses/safety switches only to have the electrician refuse to accept it.

That's a good shout, it did mention doing this for off-grid state but didn't mention it as needed for backup power (which is effectively the same I guess). Will have to get a relay.

Just one question relating to the CT clamp. I hope to connect the inverter to a fusebox in the shed which branches off of the main fusebox in the house (15-20m away) the wire is >6mm^2 so hoping it should cope. The one pain would be having to splice the CT clamp to a CAT6 and run it back through the underground pipe. From looking online, the primary use for the CT clamp appears to be for ensuring zero export in cases where this is compulsory for whatever reason. However, I want to prioritize for selling back to the grid so is the clamp absolutely necessary? Afraid the software would say no
