I’ve just returned to the boat to find the Phoenix Smart Charger inoperative. Low, Bulk, and Abs lights flashing amber; all four Mode lights flashing blue. When I connect to it using the Victron Connect app it opens Firmware update page: Current version: none; New version: v3.61. But when I try to install the new version it fails at 93%.
From the service report we can see that the chargers stays in its firmware download state (the so called bootloader) after the update. This can be caused by a problem with the internal storage or can be caused by a “sticky” button. So when you are sure that the button is not continuously pressed, there seems to be a hardware problem with the charger that cannot be fixed. I would advice you to contact the seller to have it replaced under warranty.
