can you use optimizers with an MPPT 250/60 TR?

I have10 JA solar 410W (JAM72s10 390-410/mr) panels connectec to a MPPT RS 450/100-tr, of the panels are effected by shading during part ot the day which is reducing the efficency, would fitting optimizers cure this? and is it comapable with the MPPT?

The MPPT manuals clearly state optimisers are not supported and can cause conflicts with the MPPT Algo.

It is true for networked optimisers because they transmit their data ovet the DC cable and this can heavily disturb the MPPT.


Currently I know only 2 optimiser which are system independant and work as Stand-Alone, hence you connect the solarpanel to the optimiser and with the second pair of connectors into your solar string.


And it works...

...but with a price of around 56€, I am not sure, wheter it is realy optimal.

Any and all optimisers are unsupported with Victron MPPTs.

People still do it, but if you have issues you are on your own.
