Alternates of Sofar Solar ME3000SP

[atti]

Can someone please suggest alternative of Sofar Solar ME3000SP. This product is quite good but I want to something which can be chained together to higher current draw, I want to go upto 10kw use. Any suggestion is welcome.

I have been looking in the UK at whats available for AC coupled storage and really the choices are not great this was a list i made for myself

Solis AC 5G
Sofar (ME3000SP)
SMA Sunny Island (SMA SUNNY BOY STORAGE) - only seems to be compatible with handful of batteries
Luxpower - Doesnt seem to be widely available other than direct from installers but some interesting integrations for Octopus
Givenergy (Giv-AC 3.0) - Does not support third party batteries
Solax AC - Does not support third party batteries

Hi, I am looking at the same thing (high current draw for use. So far I have excluded many inverters as they cannot be stringed together easily (or at all).
Right now I am researching the SoFAR HYD 6000-EP which seems to be a good option according to the spec.
However, I have not found many reliable reviews yet....

If anybody has experience, please help

I have an idea to use ME3000SP in the parallel. If I can put two or three inverters in the parallel and set them all in the passive mode where they need external command coming over RS485 interface from a Raspberry PI (or a computer) running python code doing the calculation of the usage and either charge/discharge either in series or in parallel. Shouldn't be that difficult to achieve, has anyone attempted something like this before?

I am trying this exact thing. its a bloomin nightmare! I am tempted to get a seperate CT clamp monitor so I can 485 the passive one to do half the current. would be so easy for the sofar to have a passive mode so they can talk to eachother but theres not that option that i know off yet.

Very interested to hear if you have solved this!

I think we can't rely on the RS485 interface of the ME3000SP as in my setup running since past one year they tend to stop working atleast once in a month and I have to restart the inverter to pick it again.

We will be better off trying a product off the shelf for this purpose, something like Squirrel POD from LuxPower.

Hello Atti,
I have the same problem with my ME3000SP. After about a month it stops communicating over the Rs485 interface. It has done it twice now. And I also need to restart the device before the communications starts working again. I am very interested if you found a solution for this issue. And if not, I am also very interested in what you have tried and didn't work. Especially since the test cycle is at least a month before we know if it is the sollution

I upgraded the firmware to version 3.12 but that was mainly so my Pylontech US5000 batteries were available in the configuration and the batteries could discharge below 20%.

I hope you can help me.

Regards,
Hein Verhoeven.

It looks there is a technical solution for the RS485 problem. I am using it now for over a month and did not have this issue anymore. Here is the link:

I had it working and pulling in the data into home assistant, but after about 12 hours it stopped and now just shows the crc fault error with the 485 error popping up every so often? Any thoughts a...
