Are you saying that the blue and yellow lines are on different scales? 1500w vs 3000w even though they lines have the same vertical height?
No, but I know that at this time of day it is 3000w what do my solar panels produce.
An inverter produces the maximum that the solar panels can deliver, if...
@Sleeper85
It works perfectly.
The blue LED flashes, what does that mean?
Inverter shows message 04 "Low battery level" since I connected ESP32. What value in your program is used for comparison?
Hello. Can you help me?
This afternoon, I was like in the photo.
I did a test, I disconnected the RJ45 cable between the SPF5000ES and the battery. Immediately, the Growatt cut off all electricity in the house and indicated an error 04 and 20 (low battery voltage and no communication with the...
Hello, in the Solar Assistant interface I have this on a certain day. What does this mean exactly?
I have a Growatt SPF5000 in USB0 and a JKBMS in USB1.
Hello, I'm French, sorry for my bad English.
I would like to know if it is better to build a 12v / 100Ah battery or a 24v / 50Ah? For what reason? Thanks you
A fault may occur on the BMS. In this case we are in the dark???
A friend has SofarSolar inverter, when he unplugs the RJ45 cable, the inverter goes immediately to the grid !!
I ain't hybrid inverters. I just want to build a storage system parallel to my solar system.
Building a 24v battery costs more because it takes twice as many cells compared to a 12v one. Wire size is the only reason?
I have 10 solar panel of 395Wc and one inverter Hypontech HPS4000D.
I would like to be able to charge a battery with the solar surplus to cover my consumption for the night. So charger (AC -> DC) --> Battery --> Inverter (DC -> AC). In fact I want to make something like Ecoflow batteries.
Hello, I connected my battery but the Growatt only charges it for a short time. The battery voltage is 54v so not fully charged. I set program 19 and 20 to 56v, program 5 is to BATT USE because there is no connection between the BMS and the Growatt.
I currently produce around 2000w, the sky is...
When I go to plug in my battery, I wish the network could never charge the battery. Only solar, is this possible?
Another example, the solar produces 4000w and the house consumes 3000w, the remaining 1000w will go to charge the battery? Will the inverter send the excess solar to the battery?
Good evening, could you explain to me the use of program 12 and 13 in the settings?
I can't go lower than 50v, for what reason?
I can put 51 or 52v but impossible to put 49v for example.
I selected User mode in program 5
I received the Jkong rs485 adapter and the rs485/usb converter, everything worked perfectly for 4 days and today the battery screen freezes, all the data is frozen.
I unplugged and reconnected the USB but it worked fine for a few moments but then it freezes again, really very disappointed...
@mrconstantin
I am French and I use Google translate.
I would like to carry out the hardware part myself, do you think this diagram could work with your program?
How can I get your program?
This system will not be alone to supply the consumption of the night, the inverter used will be a grid tie with its output adjustable from 30 to 300w, the EDF network (in France) will complete what is missing.
The 5000ES is unable to export power to the grid.
I am advised to use SBU and not SUB.
What does "by pass" mean that we see at the top of the image?
At the moment I'm like this:
Where can I find the kernel log and dmesg?
In the solar assistant settings I have this in "Configuration > System USB devices - Cycle USB power :
And this : Kernel Log in Word format.

Hello, my SPF5000ES does not charge the battery completely, it stops for no reason.
It indicates a full battery while the voltage is 53.6v. I set #19 and #20 to 55.1v so why isn't it charging the battery?
The BMS indicates approximately 3.351v per cell while the Remain Battery is at...
Should the length of the red and black wires (+ and -) coming out of the cells and going to the mppt charger be the same length or is it not important?
There is no absorption time, programs #19 and #20 have the same values as indicated in the manual. It's not good?
I don't have link CAN or RS485 between inverter and bms.
