Hi MdF, Thank you so much for the detailed information. I have made the changes, now just to monitor and see if it helps with my consumption, I am sure it, otherwise I will change the % like you said and see what differences it makes. We pretty much have the same setup, so I am sure I will be seeing the same savings. All the best and thanks again for the help and information. Jaco

Good day everyone, I was reading through allot of threads on here and also looking at You Tube videos, but they all seem very confusing to me. I was hoping to get some clarity and help please on running a Deye 5kw inverter to achieve the below. I also have Solar Assistant and 2 5.12kw Dyness batteries with 8 x 450 Panels. 1. I only want to change my batteries during the day using solar. I have set Grid Charge to off, seems to work fine. Problem is that only cloudy days when solar is not enough to power load, it uses the grid to supplement, I want the batteries to supplement and not the grid. 2. Then I want to use the batteries until about 8-9pm at night to run my heavy loads and then switch back to grid for the rest of the night until the next morning where Solar/Battery will kick in again and also start charging the batteries from solar again. The reason I want to do this, is try to use as little power from the grid as possible. From what I can gather is that I need to change the settings under Work Mode timer, but they only allow me to time start. Time end is greyed out, then is also ask power, voltage and Grid Charge, makes no sense to me. Please help.

Hi everyone, so we have found the problem. So the dip switches seems to have only sorted out the problem for a short while and the problem came back. The problem was BMS communication cable was plugged into the "Battery connector" after plugging it in the RS485 port all issues went away and we can now pull over 5kw without any errors or tripping. Thanks for everyone's help, I really appreciate it.

The other thing we have done just noe is set the dip switch on bat1 to 1 and on bat 2 and 3 al dips to off. Now it did not trip. Could that have been the problem or are we just making the issues worse?

Hi abd7, thanks for the reply. Inverter is set to 150amp discharge rate. No setting we change on the inverter serms to help. Do you also think it might be the battery cables? We are using the ones that came with the batteries.

Hi Frivan, Thank you so much. Please excuse me, I am a newbie, haha So do you think a busbar and the 50mm cable will sort the problem out even though you think the connectors on the batteries were not designed for the 300amp?

Good evening everyone, I am hoping someone could asssit me with this problem. Two weeks ago I help my brother in-law install a 16Kw single phase Deye inverter with 3 x 5.12kw Deyness batteries and 18 x 550w panels in 3 strings. Everything is running great, except when the power is out and he is trying to pull more rhan 3kw, the whole system trips and restarts and then gives a F56_DC_VoltLow Error. I have contacted Deye support and they have done a remote firmware uodate, but the problem persists. I have Googled to my wits end and the lots of people have the problem but no real solution.
