Yup, installer is also trying on their side. We play the waiting game for now😐

@PieterO, yup followed the manual, videos and every apk that they had, but it never connects

My problem is I can't get the batteries to connect to any of their Apps. I've been added to a WhatsApp group but the communication in that group sucks, very little feedback and absolutely no real drive to find a resolution 😭

@Franna99, unfortunately, still waiting on my Installer to try and sort this out 😔 @Murlin, @nam-hunt is correct, with PV it always charges to 100%, it never stops charging as long as there is enough power to charge the batteries

Nah, I thought this would've helped but it looks like it didn't. Still goes back and forth after being charged full. The CFE support guys said the Deye Inverter Firmware needs to be updated and this might solve the problem. So waiting for the update and will see if that solves the problem. Will keep you guys updated

In conversation with CFE Support, let's see what happens

The CFE support guys said the inverter needs a firmware update. Lets see if that solves the issue 😃

I for the life of me just cannot get the battery connected to the app. My Installer is trying to get assistance from CFE but we are getting nowhere to be honest 😞

I updated the voltages but still having that issue where the battery drops from 100% to 94% and then starts charging again. From the sounds of it, it's the BMS and it's not anything that we can configure on the inverter. With regards to the battery going to fault mode when reaching 100%, I had the same issue when I first got the batteries. I solved it by discharging the battery to very close to 10% and then recharging it back to 100%. Ever since then I've never experienced that again

Yup, my installer can't get that working. I think we all just gave up to be honest 😁

Interesting, I would like to know how will they update the firmware.🤔

It's very possible they done this to spread the load in the cables. If the load is too much for the thin cables, it can lead to overheating and burning cables. As long as the length of the output cables are the same, it should in theory be fine, from what I remember reading up on

I've set my inverter with the following voltages: Float: 53.6 V Absorption: 53.8 V Equalization charge: 53.8 V This seems to have stabilised that erratic discharge and charge process. Thanks @Rosh for the suggestions. Really appreciate it

Let me try these voltage numbers. Thanks

Hi @Paul.Ve, spot on what I'm experiencing. I've read some other forum that stated the BMS is what guides the inverter on what and how to handle the battery. So not really sure if there is a solution to be honest.

Hi, for those who have CFE 5100 batteries with a Deye/Sunsynk inverter, do your batteries charge to 100%, then forces the inverter to use battery instead of solar and then drop to +-95% before charging again and using solar again? My inverter is set to use the BMS and not voltages, but you can set the voltages in the background and they are set as follows: Battery float chargee: 53.6 V Battery absorption charge: 55.6 V Battery equalization charge: 55.6 V Is this normal? If not, what can I adjust to prevent this behaviour

Nah, my current voltage is on +-280V

Correct, if I add a panel or 2 more, that should increase the voltage and in turn would increase the power

Interesting @YellowTapemeasure, I noticed my Deye inverter maxes out at 9kw input, and although the inverter says maximum of 22A per MPPT, at 9kw, the current from the PV is +-20A. I actually thought maybe it's a setting that I need to change but what you are saying is making sense here. So I can't really hit the maximum 10400kw at all by the looks of it 🙁

Hi everyone, sorry for reviving a bit of an old thread but I need some clarification and advise. I'm pulling the plug on going solar and the plan is to go with 8k Deye Inverter, 19 x 545w panels with 4 x 5kw batteries. I was thinking of putting my geyser (3kw element) and oven (only oven because I got gas hob) on smart load. The rest of the entire house on essential load. Pretty much nothing on non essential load. I currently have my geyser connected to a geyser wise and I don't want to change that. So my questions are: 1. With the geyser on smart load, whether we have grid power or not, would the geyser wise always be on regardless of whether we have the element activated or not? 2. Would putting the oven on smart load be a good idea? I don't want to be in a scenario where the oven was switched on but it goes off because PV is not enough and battery SOC is lower than the 'off' setting but we still have eskom? 3. If you have "on grid always on". Is the order of preference PV -> battery -> grid or grid -> PV -> battery? Hope I've given as much information as possible to give everyone enough context.
