The problem is that if I do it myself then the warranty is voided as far as I know. That would be my preferred route, but I don't want to risk the warranty, just now something happens where I really need the warranty in the little time it is still active.

@Sidewinder At this stage it is not critical for me to sort out. I am using Solar Assistant. The only reason why I wanted to get the Sunsynk comms up again was for Freedom Won to be able to access the site and verify settings etc. It has been non-operational since Apr 2025 and didn't worry me until now. But FW managed in any case to sort out the settings on the battery which seemed to do the trick. @Yellow Measure That is quite a good price!

Thanks. I tested between 9 and 5 and got no reading at all

Thanks all. At this point I am just thinking to live with it for now and then somewhere next year when the warranty expires to just get someone that can replace the board for me. I am not interested in removing the inverter to send it in to Sunsynk to replace the board which in all likelyhood will take some time and not same day. The risk and cost is too high to go that route.

In this case the actual dongle does not get power. Therefor I can't even connect directly with the dongle to do a setup.

I have the Sunsynk 8kW inverter that was installed end of 2022. In Apr last year the dongle stopped working and eventually this year I got a new dongle just to find that the new one also don't work. I investigated this and found that there are various reports of the comms board failing which is mostly to do with the C9 capacitor. Some people just cut it out and everything works again. However I am not comfortable with that. I contacted Sunsynk but they advised me to get an installer to test the voltage and then report back to them. My question then is, where can I find an installer around Roodepoort that can assist with something as small as this? I am happy also to just replace the board and get it done with.

Hi yes, the comment was meant more as a joke. I know it all depends on general usage and no of people in the house, etc. We run a few pc's (the kids draw extra power with the gaming) and then also use aircons at night in summer, etc.

Based on my experience, I would rather use Solar Assistant than the Sunsynk app, I have both and now and again look at the Sunsynk app, however SA is just much more user friendly for me. I don't know how you guys get through the night with less than 9kWh!! 😀

Solar Assistant was also affected by the constant time changing ito the TOU schedule. Data remained intact otherwise. The solution for the TOU schedule as mentioned was just not to sync the time.

Thanks. The CBI app does not have a "history" check box also no firmware update since I got the switches. However, last night at some stage all of a sudden the total usage was updated. Very strange.

It appears if both my switches has stopped recording usage data today and the first day on record of the devices are 31 Dec 2022. Does it only hold 12 months data or could something have gone wrong in it having to erase old data and replace with new data for the months/days? It still shows the actual usage real time, but not total usage for the day. Any ideas?

He managed to return the panels the next day for a full refund apart from additional shipping cost. In the end he managed to dodge that one.

For FW the BMS cycle count still has a calculation attached to it to get to their warranty count. You take the BMS cycle divided by 2 divided by 0.8 and that is what FW work with. In practice it comes down to a discharge from 100% to 20% SOC and charge to 100% counts as 1 cycle. Which also comes down to 160% of the battery capacity (in a combined charge/discharge view) is 1 cycle.

I have seen it at our local Leroy Merlin. They also have an inverter that looks like the Deye/Sunsunk

I did and it links to a model range with a max rating of 460W Edit: I have also seen in the solar world that these companies in general are not great at spec sheets with version control. If I for instance search for a specsheet on my battery, I will get three different ones and no indication on which one might be the right one. The dimensions of the same battery (15/12) is different on all three.
