I'm working on an older solar system and have taken it out of service to upgrade some components. I have an older FM80 with firmware version 002.000.000 on it and while it was down thought to flash the firmware to the current rev. However, from what I've read I can only field flash firmware versions 002.001.000 and newer and would have to ship my unit to the factory to have it updated.
Question: I'm not current with a lot of what's changed with updated firmware revs but I do know that the firmware for the FM80 is at least up to 003.001.000 which is what a second FM80 I recently purchased is currently at. With the older FM80 out of service at the moment, would it be advisable to send it in to update the firmware which may hopefully make life easier for me in the future depending on how I use it? I realize no firmware is perfect and sometimes you trade one problem for another and it maybe better to keep what you've got. However, my thought though is that if there are issues in the future that are fixed with firmware updates, if I at least get past the 002.001.000 version I can field update the unit at some future point without having to take it out of service at a much less opportune time than now.
That said, as I'm looking through the Outback website I don't actually see any firmware updates available for the FM80 so this may not even be an issue if they aren't providing them.
