Good morning, I have an installation in operation with PV, MPPT, Batteries and a Multiplus 2 3000/48. Wishing to increase the wave power, I bought another new multiplus 2 3000/48. I would like to put them in parallel following the instructions you give (identical firmware etc.) Both models are type: PMP482305010 The one in service has the SN: 2025T6MVVP The one I bought has SN: 22389M4RF Are these two multiplus 2 3000/48 devices compatible for parallel operation? Sincerely, Philip
hi there should be HW revision sticker on them or on the box it came in
HW revision number should be the same, if not ask your supplier if they can check the serials if they can work in parallel
Inverters don't have revision numbers on them.
Those two are 2 years apart and a few years old already, some major changes were made some time around 2022.
Use the newer one as master, they should work ok, but systems that have been in use for so long often don't balance well.
It is usually not a great idea to pair systems if one is already 4 years old.
You have them already, so may as well try.
well my multiplus 2's do have revision number stickers on them...
