I have pick up 2 x 180 watts panels on pv volts of 45volt open for a price of 20 euro .

So i like to connect them on my boat using a epever with a 150volt pv input.
The controller do 20a .

So my old setup see attach files.

Now i use 2x renogy panels 100watt 22volt model.

So like to do this.
Renogy in series so i have 44volts.
The sun factory panel is parallel.
This way i have 3x almost the same volt in parallel.
This will be fine i think ?
I know the epever is only 20a but that will be soon replace for a bigger one.

I use a 12 volt battery pack

Was that a Question or a Statement?

More if it gone work to combine them with different brand.
Or that i set the renogy panels on a different mppt .and connecting it that way.
I can combine 2 epever .
By replace the one epever to a victron on the other battery pack (Victron is a spare)

The panels will replace the one on the roof .
And the renogy gone place on the side of the boat on the railing.
That will be more in the Shadow on those panels .

So i look for the best option .
Special in the winter time.
