Firmware update issues leading to Victron MPPT reporting over voltage

Hi, I have 2 independent solar panel (180W each) connected to two victron 70/15 chargers. It worked fine for 6 years.

I have just replaced one Victron 70/15 with Victron 75/15. I still have second 70/15 in place until new 75/15 is working properly.

Installation went fine, and charger produced electricity, turned form bulk to absorption as day progressed.

I have in meantime done firmware update by Victronconnect. It worked up to a point and then stopped. Error message was that device is not ready. Have checked MPPT 75/15 and can see yellow and green light blinking which means over voltage. My guess is, that firmware update confused charger, as old 70/15 worked for 6 years without a blip.

I have done update by Android phone. It has run first update and completed after few attempts. Then I tried to run the app, and ask for another update to version 1.37. So I started again and stopped at around 15%. Then gor this error. It was sunny day but nothing extraordinary. 70/15 works fine in same conditions.

Can you please advise what the issue is or what I was doing wrong.

I have used iphone to upgrade and magic happened. Hardware fault was fixed !!!

I think vicron should prohibit use of androids for firmware updates. The way firmware update software behaved on my 2 brand new android phones is appalling. Or has never been tested or android operating system is totally unreliable. Yuk either way.

Could you imagine the outrage if we said iPhone only!

It’s a frustration that all android devices don’t work consistently, but the vast majority do.

We’ll just keep doing our best to support the very diverse platform as best as we can.
