All is done !
Uploaded firmware by USB OTG. RS232 don't work with my laptop.
MCU upload by RS232 19200 bps.
After update firmware get error 32....was crying...:-)
With MCU updated and total restart of inverter (disconnect PV and batteries) all ok.
Thanks so much Coulomb !!!
Hi Coulomb,
last firmware published by Danilo is ok for my Voltronic Inverter ? (see pic in attachment)
Can I use original data cable that I've found with inverter or I must use 4 wires cable with resistor ?
Thanks.
Salvo.
