My Multiplus 24/3000/70-16 (Product ID=2616, firmware = 158) is connected via VE Bus to a Venus GX. The GX logs on to the Victron VRM via a permanently powered and internet connected router. There are occasions when I remotely turn off the Multiplus via the Remote Console on the VRM. Occasionaly (about 1 time out of 10) when I turn it back on remotely the Multiplus doesn't power up. I can hear a relay click in the multiplus so the "turn on" command is getting there but it doesn't start inverting. If I turn it off and on again this doesn't fix it. If I reboot the GX then turn on the Multi it then works ok. Any ideas?
I know that the firmware of the Multi isn't the latest (the GX is up to date). Would it be worth updating the Multi firmware? If so is it easy to do? The Victron web site suggests you shouldn't update if you don't know what you are doing. I have the means to connect directly to to Multi from a laptop.
