Ok , now I see it shows 64% ... Battery state of charge 63 -64 % Battery power 0 W Battery voltage 52.5 V Battery current 0.0 A Looking at the explanation you gave me , means I could try to cheat it to show correct values by changing the values of Flooded battery settings ... this UNLESS it calculates after the DEFAULT settings and not after the custom settings for the Flooded batteries. If it calculates after the custom settings of Flooded batteries then I can switch to flooded , modify the parameters of flooded , then switch back to USE and all should be good. For my flooded I set cut off at 46V if I remember correctly. This until I figure out why the BMS does not wanna talk RS485. Thanks for the information.

Hi guys. I'm struggling with communication between my stupid Easun MKS IV and the Pylontech and I am trying to understand how does the Inverter measures the Battery state of charge. So even if the Pylontech tells me SOC is 100% , the Inverter will always see Battery state of charge 67% even when Battery voltage is 52.5 V. Is it supid and looks at the Flooded bulk charge voltage or how does it see 67% ? So how does it calculate the SOC ? Thanks in advance.

I'll tell you in a few days when my adapter comes home Looks interesting

Looks like an MKS IV , feels like an MKS IV sold as an MKS IV , same specs .... could I be a lucky punk ? As I said, I am ready to pay for the service. Here's the manual : http://www.evosoft.dk/SM IV manual-20210323-2.pdf

Hi Coulomb Thanks for taking the time to read and reply. To be completely honest , I am very impulsive. I wanted an inverter NOW and at that time this was the only brand / model available ASAP. I guess I will have to keep it a bit more then and run with the raspberry pi until I will be able to buy a real AXPERT , MPPSolar or a Growatt... delivery time for them seems to be sometime in November Not even sure what to go with now .... Won't be possible to change the FW in it to "cheat" the clone ? Thanks again for the time.

Hello guys and thanks for accepting my registration. As most of you , I came across this forum because of some solar power inverter problems Don't hate. Long story short. I have a Axpert MKS IV 5600 under EaSunPower license for a few months now and I have been running with flooded batteries.. everything was PERFECT. Yesterday I received my 2 x Pylontech US3000C (Licensed under Upower https://www.upowerbatteries.com/) . that I run in Parallel. This batteries are 100% the same as Pylontech. Well, since yesterday at 2pm (24 hours ago to be exact) , with no sleep , I have been fighting with the communication between the inverter and the batteries. I set the Inverter to "PYL" , "Lic" or "Lib " and in a few minutes I see a short Error 04 ( Low Battery) followed very short after by the "Error 61". I checked and re checked the com cable and it is CORRECT. Made my own cable only with RS485 , then with both CAN and RS485. Rebooted batteries and inverter 1000 times... still same problem. When I set up the battery type USE then of course there is no BMS comm so no error. I can connect directly to the batteries on management port from PI and see charge state and everything just fine. Power -308 W Voltage 49.7 V Current -6.2 A Capacity 148.0 Ah Temperature 22.6 °C State of charge 99 % State of health 100 % Recommended charge voltage 53.3 V Recommended charge current 0.0 A Recommended discharge current -37.0 A Inverter Firmware : Main CPU Firmware : 00061.01 Secondary CPU : 00122.12 Just saw in a debugging log "Serial-QMN.log" that it announces itself as a VM III-5600 ? ANY help would be appreciated ! Willing to pay ! I am so tired and so frustrated... Any other information that is needed , please ask , I will try to answer to the best of my knowledge. Thanks in advance.
