I didn't see this in the official documentation, so I figured I'd ask here. What is the best way to go about updating all the firmware in a complete GridBOSS+FlexBOSS system (including Dongles)? Is there a proper way to go about it so that all the individual components can be updated without ever interrupting the load? It is fine for the load to be run off-grid while inverters are being updated/etc - I just want to avoid having to power everything off while multiple devices are updated, and then having to restore internet for the next update just to have everything go down again.
The best way to update the inverter is by placing it in standby mode. However, in most cases, people perform the update while loads are still running. Once the firmware is downloaded to the inverter, it will reboot for about a minute or two to complete the installation.
