Two inverters connected in parallel, one inverter gives the error code 19 - firmware inconsistent... I have looked around but as yet have been unable to find the firmware and update tool for this model of inverter. Easun after-sales services has been unavailable for the last days.

Thank you in advance for your assistance.
 
I bought a number replacement control boards instead about $50 each, that come with teh firmware pre-loaded, and swapped them out into each inverter. For this I went direct to Sorotech.
 
hi where can i buy a new display with new firmware for my easun smr II. i get no answer from sorrotec.
 
In order to parallel two inverters you need consistent firmware version of you control boards (not other firmwares in your inverter like display board, mppt board, ...). Maybe that's the reason why you didn't get any answer. It was confusing for them.
