Currently, we are preparing an installation of a number of cabinets for deployment at remote mine sites, each containing a SmartSolar MPPT 75/15s. For remote access to the device, we are utilizing the VE.Direct port, to connect via a Serial to Ethernet bridge to the MS Windows VictronConnect application.
The issue that we have discovered is that during firmware update, the load output of the device switches off at about the 4% mark. The SmartSolar’s load output controls power to all of the down-stream network connectivity hardware, including the Serial-to-Ethernet converter, network switch and Ubuiti WiFi radio. This causes the update to be interrupted, with no possibility of it starting again without physical intervention at the Cabinet. The latter will not be possible as the mine site will eventually be inaccessible.
Any ideas are welcome. Alternative VE direct software, how to block VictronConnnect from checking latest firmware downloads, etc would be appreciated.
