Hi,
I purchaged a MPPT 75/15 smartsolar charger (replacement of a 14 years old PWS charger) for a original 50 Watts panel (also 14 years ago), just to boost a bit of the efficiency compensating for the panels age and charger technology.
Hardware version V01.
Many connectivity issues using bluetooth from Android 10 and MacOS (seemed impossible to get connected from the android 10 device - followed all instructions related to the bluetooth specifics as per victron).
Finally using MacOS I managed to get connected. And once I have got a charging display with voltage and power (values as expected). Second time I started the app on the Mac, it forced me to update the firmware, no way around. I hit the update button and from then onwards all misery (note less than one meter away from the charger all the time).
Somehow the update failed and now it gives me firmware version: none -> please update to 1.46
Green and yellow led flashing rapidly.
There is no longer any way to connect (unpowered for 30 min as well, multiple times).
Also error D26 comes in the app (MacOs):
Updating failed, communication lost. The product might be unusable. Check connection and power supply.
Try again and check the product settings once updated.
Again, all bluetooth reset / reconnect as per Victron have been followed.
So obviously the firmware is corrupt and I'm now looking for a *hardware* reset option which I asume would load the original firmware and resets all.
Any software / app option is not what I'm looking for.
Where is it?
Thx, Jan Jaap
