I also think this is the problem. The installer came and fiddled with the settings and reset the system a couple of times and seems all is working again. Or is it just a matter of time before the bad cell bombs out again?

Thank you hilt_ctn. It did charge back to 100% yesterday, but I'll leave them at 100% over night and see if it helps.

Hi everyone I have a 10kw Revov battery connected to a 5kw Deye inverter. Yesterday, the SOC dropped from 37% to zero instantly and the batteries shut down. Once it restarted, it charged up to 100%, but it is now discharging at a much faster rate than previously. Usually, a1 0% drop in SOC equaled 1kw discharge, now 10% equals about 0.6Kw discharge. I think the cells are out of balance, is there a setting on the Deye to force the BMS to balance the cells properly? Thank you for the help.

Problem solved. The guys who came to fix the other issue moved the CT Coil. All fixed again.

Hi everyone. I have a strange issue with my 5kw Deye inverter. The CT coil and "zero export to ct" was working perfectly until I had to do a firmware update to fix another issue. Now the the non-essential load no longer shows as part of the house consumption. Only the essential consumption shows and no matter what settings I change it shows only the essential consumption. Toggling between "zero export to ct" and "zero export to load" makes no difference to the house consumption reading. Any advice will be appreciated.

There is no comms between my battery and inverter, running on voltage mode, back when it was installed Revov could not communicate with Deye. I know they can now so maybe it's time to fix that. I'm letting it sit on 100% the whole day, so hopefully it will recalibrate itself. Thanks for the reply.

Good morning everyone, I need some help please. I have a 5kw Deye inverter and a 10Kw Revov battery. It's been working perfectly for 4 years, but recently the inverter has been drawing down the battery too much at night. My settings stayed the same with the time of use set to discharge the battery to 40% at night. The inverter still shows 40% in the morning, but the battery is below 20%. The inverter and battery percentages used to be spot-on and I did not change anything. Any advice would be appreciated.

I think your problem is with the time slots, it needs to run sequentially from 00:00 in the first block. Start your first block (top left) with 00:00 (12 at night) and end your last block (bottom right) at 00:00 again, so you cover 24hr from top to bottom. There are some threads on here that discuss how the inverter does weird things when not programmed this way.

Hi Duane, I had a similar problem. Turned out one of the fuses in the battery disconnect fuse holder burned. I replaced the fuse and all was ok again.

So it seems a blown fuse caused the problem. Not sure what would have caused this. I will replace and see how it goes.

Hi KBS, start your first block (top left) with 00:00 (12 at night) and end your last block (bottom right) at 00:00 again, so you cover 24hr from top to bottom. Might work, I know the Deye inverters are finnicky with the time slots.

Not yet, I'm back home tomorrow and will report back. Very difficult to try and figure out a problem remotely.😟 Thank you.

Here is another view with the battery voltage included:

Hi everyone Yesterday round about the time of the big storm in JHB, my SOC readings on my Deye inverter went haywire and since then it won't charge the batteries at all. The voltage reading on the inverter equals the float charge voltage, even though I can see on the batteries that they are 50% full. So it just sits at 100%. Any help please? Thanks

I did exactly this, but now my meter only connects if that specific aircon is switched on 😣.

Thanks guys. Seems I will need an electrician as I have no plugs on the grid side 😟

Hi everyone I've just converted to pre-paid electricity and have a small problem. The unit in my house does not connect to the outside meter when my inverter is working. If I bypass the inverter and draw straight from the grid everything is fine. Has anyone had this problem that can share a solution? Thank you

Can anyone recommend an ITS heat pump installer in the JHB, West Rand area?

Thank you

Yes I have the 2nd life version, but they are still supposed to give 4000+ cycles.

Hi everyone I have recently installed a 10kWh Revov battery, a Sunsynk inverter and 3.3kw solar panels. I am trying the get the most of the battery and solar during the day, while still having enough battery backup left for load shedding and power failures when they happened. I'm managing the power as follows (currently working on Voltage settings, so a bit tricky): From 4:00 to 9:00 the battery discharges to approximately 80%. From 9:00 to 15:00 the battery charges back up to 90% on holds at that % using solar only. From 15:00 to 17:00 the battery charges back to 100% using solar only. From 17:00 to about 4:00 the battery stays at 100% using grid power. So my questions are: While the battery holds at 90% during the day it is constantly charging from solar when excess solar is available and then feeding back into the load when the SoC goes over 90%, is this good for the battery? Can those small charge discharge cycles be maintained for hopefully 10 years? Any other advice will be appreciated. Thank you.

Thank you for the replies. I've got limited roof space so can fit max 10 panels. Will see how the system copes with the geyser and then take it from there. Seems the Goodwe is a good all rounder to install, slotting in nicely between the Axpert and the Victron in terms of cost and functionality.

Thanks Otto that helps. I will convert the Geyser to solar at a later stage and then I should be ok consumption wise. Probably changing the Axpert to a Goodwe. From what I read the Goodwe will manage the power sources better, ensuring solar is fully utilised before switching to battery and then grid. Can anybody confirm this?

Hi everyone. I'm new to the forum and need some advice on a solar set-up I'm considering. Been reading a lot but I'm more confused than ever. The specs are: 1 x Axpert 5kVA inverter 10 x 330w solar panels 1 x 10kWh Li-ion battery My daily consumption is about 30 KWh (geyser is on grid power). I want the setup to reduce my electricity bill as well as provide loadshedding backup. Ideally it should utilise PV for loads and charging the battery, then battery power and lastly grid. It should also bypass straight to grid if the load is high. My questions please: Is the setup the correct size? I'm not sure if the inverter is suitable, are there better options for not much more cost? What would a setup like this cost fully installed, ball park figure? Thank you for the help. It is much appreciated.
