Victron Multiplus 2

Good day

I have the Victron Multiplus 2 - 48V/5KW and a 48V/5KW lithium battery.

I want to add 10 Jinko 470W panels on the roof.I want to connect the panels in 2 strings with a combiner box then to the mppt.

Can i connect the mppt directly on the battery and will it charge it correctly and will the excess power go the inverter and not use the grid?

Is there other components I need from Victron to charge my battery and use the excess power in my house without using the grid and to monitor the system?

I am new to Victron equipment and theres allot.

Hope someone can help thanks.

I've recently gone through the process of trying to get up-to-speed with all this. I found these useful starting points:

Serach google for 'On Grid Storage & Self Consumption' which returns a list of various suppliers - their parts lists for kits helps with identifying what components are needed.

@Jacob12

You will need a GX like the cerbo or something for monitoring.

What Mppt do you have? And have you used the victron online calculator to check your config.
