I went through almost exactly the same efforts/process as you but not changing from 240 to 230V. I did it this morning and hoping for the best ... Since my trips mostly happened when the batteries was at 100% SOC I tried to set the max charge voltage to 52.3V to prevent the batteries to get to 100% but limit to 99%. Maybe its my imagination but I think that did help to limit the frequency of trips. Hopefully the running on 230V will do the trick and no more trips ... 🙂 Edit: Can you please also make a noise about this at Lux-Power tech support. Although this a an effective work around, it can not be considered a permanent solution. The more of us complaining the better chance of getting it rectified, maybe with a firmware update or maybe with a product recall to fix it.

My Lux-Power SNA 5000 is still tripping when in EPS (mains off eg during load-shed) mode. The supplier did update the software but it still happen randomly sometimes. Weird thing is there is always very little load (less than 10%) when this happen. Any help please will be appreciated.

Thanks @QuintenRowland I got my Orange PI and its working 100%, communicating with the inverter wirelessly and no cable to the batteries. For now its read only since its a very new Beta release. Also there are some glitches that need fixing that I already pointed out to the SA team.

Unfortunately my batteries only have a "in" and "out" (RS 485 I assume), there is no RS232 port or any other ports on it .... 😒 See attached ...

Its on their website, according to them the PI (SA) communicate, real time, wirelessly via the dongle .... 🙈 https://solar-assistant.io/help/luxpower/configuration Not sure if and how well that is going to work ....

Thanks. They only added support on 22 Jan in a Beta release for Lux-Power, how are you able to use it for over 2 years? SolarAssistant do respond to my questions but very slowly and also dont answer all of my questions .... 🙈 This is what I sent last, maybe you have the answers: Since there is only one RS485 input on the master battery, do I remove the current LAN cable between the master battery and the inverter completely and connect this cable with USB (Orange PI) to the Input on the master battery? If yes, how does the communication work then: Battery BMS communicate with SA on the Orange PI SA then communicate (wirelessly) with the dongle (data logger) on the inverter? This then control the charge & discharge rates? What if the dongle (data logger) is inconsistent and not always connected? I’m having this issue with mine, waiting for a warranty replacement.

I see SolarAssistant recently added support for LuxPower. Anyone tried this yet? I'm keen, but first want to know all the ins & outs. @SolarAssistant I sent an email requesting info, can you please get someone to attend to this?

On the "Maintain" page, everything that is available on the inverter (like battery type) can be set and not limited as for a "end user" account. Also under maintain more tabs available: "Set Record", "Remote Update", "Update Record", "Autotest". All the rest is exactly the same as before.

After asking many times, the supplier created an admin account for me at last ...

Is there anyone that can assist me to create a "administrator" account for my Lux-Power 5kw SNA inverter ONLY? I asked the supplier multiple times but they are completely reluctant to oblige.

That is exactly how it is setup and there is communication between the two but it still tripped in EPS mode. However, after the last round of firmware updates and I replaced the LAN cable, it seems to be stable & working now. I'm still cautious to load it as little as possible during load-shed (EPS mode), and so far so good. Thanks for the interest.

I was wondering about that, in some places the wires are swapped and other not, now that make sense. After multiple firmware updates and a different cable, it seem to be working now. Almost through load-shed and its taking load for a change without tripping, so I'm hoping thats the end of my issues .

AGREE !!! I been begging my supplier to create an "Admin" account for me so I can do it myself, but so far they were very reluctant to comply Did you succeed? Please share.

It would seem that there is proper communication, get SOC feedback, correct charge/discharge currents, number of batteries, battery capacity etc all correct. I tried a number of different cables between the master bat and the inverter but it didn't resolve the issue. Also there is no error feedback from the batteries or inverter, how else can I check for proper communication?

I have the same issue, EPS keep tripping. I have communication between the inverter and batteries. Setup as follow: 1.) Lux-Power SNA 5000 2.) 3 x Mecer M3000 (Same as Dyness B3) 3.) 8 x 455W PV panels The supplier updated my firmware but the problem remain. EPS trip as low as 3% load sometimes with error 28 (EPS overload). When Eskom is on and the load is taken up by solar and/or batteries, it never trip! Also if the inverter is set to Lead-Acid it doesn't trip at all. Obviously I don't want to run like this indefinitely, much better to work with SOC and for the battery BMS to control the charging. Anyone with some advice/info? @Tommie6.5 did you mange to resolve your issue? If yes, how?
