Wow! So much more than I could ask for! Thank you for the knowledge and your time for writing this up. I will do thing as per your suggestions and will set things up so I have the batteries almost fully charged, then I will set the inverter to manual mode and bypass grid power so battery is not...

I have 3 Coolithium 48V 200Ah (15S) batteries. I have BMS communication set up wit Growatt SPF5000ES. The charge voltage is set to 53.2V by default by the BMS (?) and I cannot change it in the inverter's interface. I guess it is controlled by the BMS. 53.2V is 3.546...V per cell. First...

That spike is due to switching over to grid power. My grid voltage is around ~240V while inverter output voltage is 230V. So I don't see anything out of the ordinary here and according to the manual it should cause no issues unless the grid voltage is above ~260V. Also I assume if over voltage...

An interesting find is that it seems like the switchover happened just as the sun was coming up and PV voltage reached around 100V.

Hi, thanks for your reply :) I don't see any error like that not in the mobile interface nor the web interface. Also It is highly unlikely as it was in the early morning. My load was around 100W so ~2%. and temperature is a steady 18 degree Celsius, so it shouldn't be an issue. Although even it...

This morning at around 6am my growatt 5000 SPF ES for no apparent reason transferred to grid power. Battery was at ~64%. Settings are: AC output: SBU mode Charging: Solar only Back to AC: 30% SOC Back to battery 40% SOC Undervoltage cut off point: 20% Battery Type: Li (protocol 55) 3x 48V...

Hi, I see this is an older post. Im in the same boat. I'm wondering what the resolution was in your case. Here is mine: https://diysolarforum.com/threads/lifepo4-battery-drops-from-22-to-0.64445/

Apprechiate your help, Charging to 100% atm.

That literally is what is happening. Once i connected the BMS communication successfully, all the voltage values on the inverter changed to % values and from then the battery controls the charging through the inverter and the inverter only shows %. I got the values from the interface though...

Controlled by the BMS. Does it matter in this case?

I have BMS setting 36 (CAN communication protocol) set to 55.

I got this from the logs.

It just got charged to 100% 1-2 days ago.

Funny enough... it got charged to 100% just yesterday or the day before that rather... I do have AC grid connected. System voltage is 48V Coolithium LiFePo4 battery s15 My setup with BMS is: Low voltage disconnect (setting 21) is 10%. Switch over to grid (setting 12) is 20% Switch back to...

I do have BMS. Connection is up between the battery and the inverter.

Error 52 according to the manual is "Bus Voltage is too low"

Sorry, didn't see the reply. Yes I got them from a local dealer, worked fine for weeks, First issue occured yesterday. Dont know if its battery or inverter related. See: https://diysolarforum.com/threads/lifepo4-battery-drops-from-22-to-0.64445/

I have a Coolithium LiFePo4 battery with a Growatt SPF 5000 ES inverter. I have been using it for a couple of weeks now. I have it set so the inverter dicharges until 20%. Yesterday night the SOC dropped from 22% to 0% inmediatelly And I woke up in the morning with no power and a 52 error code...

Hey awesome people of this forum, Could you please help me figure out, how am I suppose to connect the Epever BMS-Link converter to my battery pack based on the instructions attached? I am trying to create my own cable, but I cannot figure out what is wrong. The above manual is for the Battery...

I'm about to get one of these next week. Probably I will set it up by the weekend. Will come back and report.

So you are telling me, that not only do I have to struggle with your cloud service for the last 4-5 months (BTW it is down again), it will take an other half a year till you fix it and not only that I will have to buy another wifi module? Just so I get this right...

To be more precise, I would only like to drip charge (trickle charge) my 48V battery from the utility with 2A... so no more than ~100W. That should be possible with this setting right? I cant seem to get a lower charge rate than 550W from the utility. ~10-12A

Did you manage to figure this one out?

Hi friendly people of the forum, Here is my situation. I have the mentioned inverter. I am trying to set a new setup for it. I have Inverter priority as output. I have been using it with Solar Only input, meaning, the battery will only be charged by the PV. I want to change the settings to...

Yes. Support got back to me again, confirming it was an issue with the backend server. It is fixed now.

Yes, Thank you for the reply. I managed to figure it out. I don't know why it is not mentioned anywhere, but (at least on Android) not only you have to enable Bluetooth and GPS but you also have to enable nearby sharing only than the phone can communicate with the module to set up the wifi. I...

Hi all! I found this forum after days of trial and error. I read through the topic and although I got some steps cleared, I still cannot get my DB9 WiFi module to work with my UP-HI 5000 Charger/inverter. I managed to get a cloud account with the help of epever support. But It seems like my...
