Does Victron have a Dual input mppt?

I want a mppt capable of at least 2 separate strings with different voltage, combining and converting the two to battery. Fully utilizing both strings?

If the answer is you need 2 different mppts, one per string, then how can I merge the two mppt’s to provide stable output to battery?

Also can the victron mppts limit current to the battery. If yes, can I in the settings choose for the excess power to be added to the voltage? (Higher voltage).


I plan to feed power stations that can handle different voltages. (But not two different voltages)

For small systems, use VE.Smart Networking.

For larger systems, add a GX device.

There is also the RS MPPT option (for large systems).

Thanks. Seems VE.Smart Networking can solve it.

I still need answer to; if I limit the current to e.g. 12amps on each mppt, can I have the excess power convert to increased voltage instead? Let's say I set the mppt to 24v and limit the current to 12amps, what happens to the excess amps the PV produce/injects? Is there a setting where I can utilize excess power when setting an amp limit on the mppt bellow PV.
