Sunsynk (DEYE) Hybrid Inverters

Due to frustration with my solis charge/discharge rates have decided to upgrade to a sunsync/deye. Have just read the entire thread and got some great info, thanks all. Couple of questions before I try to buy one.

For those who swapped out a solis inverter how straight forward is the swap, i.e. does the sunsynk use the same circular connectors as the Solis? If not are all connectors included with the sunsynk?

The other thing that annoys me with the Solis is the constant small draw from the grid. I have a large battery and good FIT rate so would rather have a constant small export if possible. From reading the thread it looks like this is possible with the sunsynk? Is this an easy setting to adjust? Thanks again!

Thanks a million. Very useful info. Anyone have a good source to buy sunsynk/deye? Only sources I can find are UK based and I try to avoid that because I have been hit with tax a couple of times. Any EU sources? Or is there a way to buy from UK and have all taxes paid up front?

I contacted rexel/kellehers this week and they said they are not doing them anymore (Focusing on Huawei brands) So now I am going the GB/NI route.

Happy with my 5kw Deye, but I was wondering about my battery charging limit. According to the specs, it can charge at 120A. I've set max charge/discharge to 115A (DC breaker has a limit of 125A, so wanted it a little less). But in reality, I see it tap out at around 4950-5000w (~97A). It doesn't _look_ like my BMS is limiting the charge (5x 16s LiFePO4 batteries, 5kWh each). Anyone seen something similar? It's not a huge deal, but a couple of extra amps would be useful with the relatively short grid charging window I've got.

Hi All,

I’ve taken the leap and ordered a Deye 8.8kw inverter to replace my Solis. There are a few reasons for this. The primary one is that I want to be able to charge my 40kwh battery fully during my short night window.

While I wait for the inverter to arrive, I’d like to purchase/upgrade cables and accessories so that I’m not trying to do it afterwards.

 Here is what I’m thinking; I would like your thoughts.

1.    Replace my Projoy 125A disconnect with KETO 1 Battery Disconnector with 200A Fuses

2.    Upgrade my T-Fuse (between battery disconnect switch and LIVE) to 200A

3.    I have 35mm2 battery cable mostly, should I upgrade this to 70mm2?

a.    If so are lugs required for battery cable connect at the inverter end?

4.    My current RCB0 is 32A, should I upgrade this to 50A? (The inverter is connected to the board in my garage, which has a 63A main fuse in it). My consumer unit feeding this from the house is 80A.

5. The current cable from the inverter to the consumer unit (10-meter length) is 6mm2. Should I upgrade this?

6.    If upgrading the battery cable I’ll need lugs

7.    I can replace the existing CT with the one that comes with the Deye. The existing CT is wired into an Acrel ACR10R bidirectional energy meter. Should I change this?

8.    There is a Garo 45A meter (model GNM10) connected to the existing RCB0. Do I need to change this?

 Anything else I’m missing?

For those of you that have the 8Kw do you charge your battery at the full 180/190A?

Thanks

Thanks for the details. On the 10sq, if I go to the electrical factors tomorrow am I just asked for 10sq twin and earth?

Any good online sources for the battery cable other than Amazon?

I'll use the CT with Deye. Do I need a meter?

Where did you order the sunsynk from?

Thanks, might go down the Alibaba route myself as I'm not in a rush. Was it from lovesun company linked earlier in the thread?
