I have 3 multiplus 48/5000/70 inverters connected to a 15kw Fronius Symo solar inverter with 18kw of solar panels. The other night when the generator switched off, one of the multiplus overloaded & didn't recover until I turned them all off & back on again. There was no load apart from house light. Is there a fault with it?
You're running very old firmware on the inverters (209) please first update to the latest firmware on the Multi's
Also update the CCGX to the V2.32~2 release candidate just to be sure.
How do I update the firmware on the inverters? Don't they update automatically like the ccgx does? I checked the ccgx & it said that it had the latest version.
Hi @Daren Connor
You can read it here:

If your not familiar with this, it's usually best to ask someone with more experience (like an installer /dealer) to do this for you / together with you.
I just checked the multi's & they are running firmware version 209.
You can only update the firmware using a MK2 or MK3 unit.
note when you do update the firmware this will reset the Multi,s to there default settings and everything will have to be resetup
so I would sugest that whoever set these up maybe you should contact them to do the firmware upgrade for you
