Thanks again for the firmware. But they are not the problem. It switches quickly from SBU mode, and from 1 minute to 20 on SBU. If you leave the SBU mode and turn off the network, and then turn it on, it remains in this mode. I still soldered the WiFi, I will see tomorrow if the data is transferred normally to Homeassistant. Without the module, the firmware runs at the same speed, with the module it always changes. Today again there was an error 32 during the firmware. Without WiFi module 2 firmware without errors. It is connected to Rx Tx +3.3 Gnd, it can affect the firmware process. But this is not accurate. A little disappointed with the purchase, after a similar PowMr, with which there were no problems at all, except that the MPPT started to work from 1A - 0.5A in the firmware + 0.5A measurement error. I will get used to it.

I see on the forum that many people have error 32 on the inverter after the firmware. Yesterday, when I started the firmware from the folder on disk D D:\Voltronic\dsp_374.04_patched_05, 3 different firmwares from this folder, the scale in the program always reached 99% and an error. The inverter also has error 32. For the fourth time, I unpacked the firmware to the root of the C drive C:\dsp_374.04_patched_05 and there were no more errors. Tried 2 more times, no errors. Maybe it's just me, I don't know.

Thank you, I will try to flash it in the evening. I use a full COM port. Why do I think that the firmware, because all data in homeassistant is transmitted at intervals of 5 seconds, except for solar energy, it can be updated once in 10 minutes, the display is normal. This was not the case before the firmware. I really liked your firmware, but I don't understand which firmware is better to replace. I will try.

Good day. I am writing through Google translator, so there may be mistakes. Please tell me what to do. I bought a Voltronic MKS IV 5600 inverter, the firmware was there U1 74.02 U2 122.12 Changed the firmware to dsp_374.04_patched_05. The inverter began to behave incorrectly when I want to change the SUB mode to SBU, the menu shows that the mode has changed, and the relay can switch after 1-2 minutes. You change the charge current from 30 to 40A, go to the menu, but it has not changed. It may change after a few tries. Is the U2 firmware not compatible with the U1? Need to revert to 74.02 but I can't find it, will U2 update?
