Detailed info of Smartsolar Mppt routine and DC conversion efficiency

Good morning,

I would like to know if it is possible to get some information about the technical specifications of the victron smartsolar, from the victron staff.

In particular:

- the efficiency curves at various powers and mpp voltages.

- the working frequency of the processor

-adjustments per second of the MPPT routine.


I am evaluating a controller with an almost flat efficiency curve at any power at 99%.

And a double mppt routine with 6,000 changes per second.

And a 30mhz processor.


I noticed that the victron smartsolar in boost-mppt seems to vary the voltage up and down a little faster than once per second.


I also noticed that in case of partial shading of 33% of the panel longitudinally on purpose, the controller stays for 3 minutes on a false MPP losing 2/3 of power. (Negative fact).


Only after 3 minutes does it find the true mpp at about half voltage and recover all the power possible.


I also noticed a full swap of the voltage curve every 10 minutes lasting 10 seconds.


And I noticed that in case of sudden load increase from no-mppt phase to mppt phase the controller performs 4 complete swaps of the voltage curve (positive fact).


Thank you
