Hi guys,
I have an Axpert 5KVA which I purchased in 2013. It is obviously a few firmware upgrades behind as I do not have the settings on the inverter from option 30 upwards.
I managed to get hold of the 72.70 version of the firmware and would like to upgrade.
2 questions:
a) can I perform the upgrade whilst the inverter is in situ, i.e. still connected to panels, batteries, utility and providing power to the home?
b) i scratched around and found a cable supplied with the inverter at the time of purchase. It has a female serial plug on the one end (which I assume plugs into my PC serial port) and a RJ45 (male network connection) on the other end (which I assume plugs into the inverter. Can you please confirm whether this is the correct cable to use for the firmware upgrade?
Tx in advance.
