Thanks for the reply. So many varying opinions. My temps range between around 65 and 70 which means that the fans inside the inverter are constantly running as the fan kicks in at around 65 degrees too. For me this doesn't feel fine. I am not sure if the fan inside the inverter is brushless, if not surely its going to eventually give up trying to cool the unit down. Friends of mine with the same inverter in a garage with similar ambient temps vary between 55 and 60 and on odd occasions more than 65 where the fan kicks in.

Yes, I did change the settings, and as you mentioned, I see that there is now a fixed charge regardless of state of charge. Even now the battery is charged but its charging. I dropped the max charge setting down further as this cant be right. Now charging at 500W which still feels high. I'm sure its suppose to be much lower than that. More like 40W to 50W. Yes the correct cable and proper comms will be the final solution, but not sure if I should drop the max charge down even further?

@Steve87 Thanks for all the information. Sorry but I have to admit, some of this is going over my head, being new to this game I have sent you a direct message, thanks again.

Yup DC side. Interesting is that SOC is available in the graph even though the BMS sections on the inverter are blank, batt temps -100 degrees etc. Yesterday when set to Lithium mode : Today since changing to "USE batt v" mode :

Hi, thanks for the reply. I will send a pic shortly. Regarding the battery comms, thats valuable information. I honestly am not sure if all of the correct processes were followed there. The installer tried using the cable that came with the inverter and the cable that came with the battery. It was plugged into the CANbus port on the inverter and on the CANBus on the battery and followed the instructions here : https://www.hubblelithium.co.za/deye, but all we see is : but as you mentioned there is much more to it. I will check with the installer. I am in the JHB area. I will DM you, thanks again.

Yes he said he did. No cloudlink setup. Thanks

Thanks for the information, My firmware version is : HMI : Ver 0000-C35A MAIN : Ver 0-3374-1515 So the inverter is set to Lithium mode. The inverter is also running in normal mode. Hope this is what you are looking for? Sorry I am a newbie in this space, so learning as I am going along. My install was last week and I have learnt quite a bit so far.

So these are the current settings. Seems to be aligned to whats on the hubble website for the am-5 : https://www.hubblelithium.co.za/deye Thanks for the suggestions. So will that be the Use Batt V setting in the screenshot above? Its currently set to Lithium. I did lower the A charge and A discharge over the weekend and the temps still were the same. However, to protect the battery and inverter I will put those charge and discharge settings back now. The installer did come out again this evening to inspect it and verify the installation and check why the Batt comms aren't working. He double checked that the Deye CANBus cable is attached to the Hubble battery CANBus port, but still no communication. We found this odd as based on https://www.hubblelithium.co.za/deye , the deye inverter and the Hubble AM-5 should have full communication and it is compatible. The installer is following up on this. It has a fan thats always spinning. Its not very loud but you can definitely hear it spinning away. So does this mean I might have an old version even though I just bought it last week? My model is SUN-5K-SG01LP1-EU 5KW DEYE. Either way, it seems like the newer version also has heating issues as you say. Thanks for the input everyone, as things stand I have an over heating inverter which has no comms to my battery. Will keep this thread posted to see where this goes.

Fully agree. The installer has been great, he has come out a few times to try and troubleshoot settings and double check the installation and from his inspection the installation seems to be fine. However the supplier/distributor is saying "it is normal" and even pointed me to this forum to see for myself that its normal. I dont think its normal for the inverter to be running this hot 24/7 (even with the little internal fan spinning away making little to no difference) I have been chatting to buddies that have the deye/sunsynk/fusion inverters, all of their inverters are running with lower temps with the fan hardly ever coming on as their inverters dont even reach 65 degrees.

Thanks for the help and input and that graph. I wasn't comfortable with the high temps so I am running extra fans until I find the actual cause of the high temps. So find a cure instead of addressing the symptom Regarding the BMS, yeah, need to address that too asap. Thanks for the reply. Yes, I fully agree, my temps are not good. Thats why I really want to fix it. Surely this fancy piece of hardware cant sustain such high temps? I checked the deye manual and the operating temp should be 25 degrees to 60 degrees. Regarding the battery comms, I have spoken to my installer and he said he will sort it out asap. Thank you. An inverter running blind cant be good

Hi Everyone, Hope that someone here can help or point me in the right direction. I have a SUN-5K-SG01LP1-EU 5KW DEYE hybrid inverter purchased and installed last week. I also have a single 5.1KW Hubble am5 lithium battery installed. It is working as a backup solution so no solar panels, however the unit is always running at very high temperature, even when not using the battery and using grid power. Most of the time the temps are running between 65 degrees celsius DC and 70 degrees celsius DC. And the internal fan is running 24/7 (always on) . The inverter is installed in my garage and the garage does get hot sometimes, however I have the same issue even at 3am in the morning when the garage is really cool. This is not correct right? These temps feel too high and the inverter gets quite hot to the touch. Any suggestions or help will be greatly appreciated. Could the unit be faulty? Could it be a setting? As the unit was installed just last week, I did raise it to the supplier but they said that this is normal. Surely this cant be normal? From the videos and articles I have seen online, it looks like the inverter fan was meant to only come on at 65 degrees and not always be spinning like crazy trying really hard to bring down temps. Some other people that I spoke to who have the exact same inverter as me says their fans only sometimes comes on when the battery is charging and then goes off again. I did see some of the other threads on this forum where some guys are running fans 24/7 but I rather fix the issue at hand rather than doing a counter measure. Another note, it seems like the Inverter and Battery are not communicating as I dont see any battery stats. Could this be a contributing factor? The Hubble website says that the AM5 battery is compatible with Deye : https://www.hubblelithium.co.za/deye Many thanks for the help.
