Multiplus2 serial number compatibility

Will a Multiplus2 S/N HQ 2236YTJF7 work in parallel with a Multiplus2 S/N HQ 23147UFMF when both updated to the same firmware version? Thanks.

Hi, yes since there not far apart it will work

Parallel can always be a bit tricky

Follow this guide and it should be ok

@MattFR

It's a matter of hit and miss. My 2 Quattros are 4 years apart but surprisingly, they work fine. My Victron agent looked at the chips of the 2 inverters and concluded that they would work. They are running the same firmware version. The imbalance is merely 3%-9% depending on the amount of loads. I was targeting 10% so I'm very happy without having to do anything. Some people here have problems even when their inverters were manufactured in the same week.

Thanks. It does sound like pot luck. I'll just have to try. Doesn't say much for Victron's products if there is so much variability and compatibility issues.

You are right but Victron recommends that inverters be of identical hardware and as close as possible regarding the time of manufacture. I guess I was just lucky.
