I think it's cheap version
also serial try to detect inverter protocol at boot and fails 3 times.
from solar2mqtt.
you say sometimes it works, so the autodetect have a try limit.
try reboot until it find the right protocol or get a answer from the device, typical it sounds a communication problem between the in verter and esp.
take a look at the chip on your pcb, the text marking tell you what it realy is
from solar2mqtt.
After some reboot tries it detects the inverter and protocol is PI30.
from solar2mqtt.
when it found the protocol the esp run normal, then you can check the serial/webserial for error log?
from solar2mqtt.
When it finds the protocol it starts getting data and working fine.. everything works perfectly. The problem is when I restart or power off the nodemcu the communication is lost. After some reboot tries it again gets connected. Like there is no reliability of the connection.
from solar2mqtt.
strange, normaly the autodetect works fine.
can you show up your wireing / setup ?
the most inverters have a power line on the rj, make sure there is nore shorting that the voltage drops
